This application claims priority of Chinese Application No. 201410168588.1 filed on Apr. 24, 2014, Chinese Application No. 201410366721.4 filed on Jul. 29, 2014, and Chinese Application No. 201510037388.7 filed on Jan. 23, 2015, the entire contents of each of which are incorporated herein by reference.
This application relates generally to management of supply of service, and in particular, management of supply of service using a network-based, e.g., Internet-based, system and method.
On-demand services, such as fleet management systems employed for taxi and limousine fleets, typically use onboard metering devices, radios, and cell phones to dispatch drivers. Such a system typically is not communicative to or does not monitor the distribution of customers that are waiting for pickup.
This application relates generally to management of supply of service, and in particular, management of supply of service using a network-based, e.g., Internet-based, system and method. A system disclosed herein may identify areas that are under-served or over-served based on the distribution of service requesters, service providers, or the like, or a combination thereof.
In one example, a system having at least one processor, storage, and a communication platform is provided for managing supply of service. The system includes a collection module configured to receive a plurality of orders for a service, an identification module configured to mark a locus based on the plurality of orders, and a determination module configured to identify at least one provider of the service to whom information relating to the marked locus is to be delivered. The marked locus relates to a first number of orders of the plurality of orders, the first number of orders sharing a first characteristic. The marked locus relates to a first location. The first characteristic may be that a distance between the first location and a location relating to an order of the marked locus is less than a first threshold. The collection module may be configured to receive at least one piece of information selected from the group consisting of, e.g., an order location relating to an order of the plurality of orders, a provider location relating to a provider, an order acceptance rate relating to the plurality of orders, an order acceptance rate relating to the marked locus, a traffic condition relating to the marked locus, a road condition relating to the marked locus, a weather condition relating to the marked locus, and historical information relating to the marked locus.
The collection module may further include a location information collector configured to identify the order location relating to an order of the plurality of orders. The location information collector may include a receiver configured to communicate with a positioning device relating to the order. In one embodiment, at least one order of the plurality of orders includes location information of a user. The location information may be determined based on a positioning signal from a device associated with the user. At least one order of the plurality of orders may be received through a network, e.g., the Internet.
The identification module may be configured to identify a locus. The locus may be identified based on one or more cluster algorithm. The identification module may include at least one unit selected from e.g., a historic information processor, and an order information processor, a provider information processor, a contingent information processor, or the like, or a combination thereof. The order information processor or the provider information processor may include at least one unit selected from e.g., a location information processor, a distance calculator, a time calculator, a miscellaneous information unit, or the like, or a combination thereof. The information processor may include at least one unit selected from, e.g., a location information processor, a distance calculator, a time calculator, a miscellaneous information unit, or the like, or a combination thereof. The cluster algorithm may include CLARANS, PAM, CLATIN, CLARA, DBSCAN, BIRCH, OPTICS, WaveCluster, CURE, CLIQUE, K-means algorithm, hierarchical algorithm, or the like, or a combination thereof. The identification module may be further configured to identify a second number of providers relating to the marked locus. The second number of providers share a second characteristic. The second characteristic may be that a distance between the first location and a location relating to a provider of the second number of providers is less than a second threshold. In one embodiment, the first characteristic (that the distance between the first location and a location relating to an order of the first number of orders is less than a first threshold) and the second characteristic may be the same, and the first threshold and the second threshold may be the same. The first number of orders and the second number of providers may be located in the same locus or region. The identification module may be configured to mark the locus based on a determination based on the ratio of the first number to the second number. For instance, the identification module may be configured to mark the locus based on the determination that the ratio of the first number to the second number exceeds a third threshold. In another embodiment, the identification module is further configured to identify an area. The identification module may be configured to mark locus based on one or more orders relate to the area. In another embodiment, the identification module may be configured to identify or mark the locus based on a determination that the first number or the second number exceeds a fourth threshold. In an embodiment, an area may be identified as a locus, and be marked such that the information relating to the marked locus is delivered to one or more requesters, one or more providers, or the like, or a combination thereof. The criteria for identifying a locus may be the same as the criteria for marking a locus. Merely by way of example, an area is identified as a locus if the number of orders with the area reaches or exceeds a threshold. The identified locus is marked such that the information relating to the marked locus is delivered to one or more requesters, one or more providers, or the like, or a combination thereof. In another embodiment, an area may be identified based on a first criterion (or criteria), and the identified locus that satisfies a second criterion (or criteria) is marked such that the information relating to the marked locus is delivered to one or more requesters, one or more providers, or the like, or a combination thereof. The first criterion (or criteria) may be different from the second criterion (or criteria). Merely by way of example, an area is identified as a locus if the number of orders with the area reaches or exceeds a threshold. The identified locus is marked if the ratio of the number of orders within the area to the number of providers within the same area exceeds another threshold. The information relating to the marked locus is delivered to one or more requesters, one or more providers, or the like, or a combination thereof.
The determination module may be configured to determine to whom the information relating to a marked locus is delivered. The determination module may include at least one unit selected from e.g., a historic information processor, and an order information processor, a provider information processor, a contingent information processor, or the like, or a combination thereof. In still another embodiment, the system further comprises a delivery module configured to deliver the information relating to the marked locus to a requester relating to an order of the marked locus, or to the at least one provider.
In another example, a system having at least one processor is provided. The at least one processor performs the operations including, e.g., receiving a plurality of orders for a service; marking a locus based on the plurality of orders, the marked locus relating to a first number of orders of the plurality of orders, the first number of orders sharing a first characteristic, and the marked locus relating to a first location; and identifying at least one provider of the service to whom information relating to the marked locus is to be delivered. The system is adapted for managing supply of the service. The first characteristic may be that a distance between the first location and a location relating to an order of the marked locus is less than a first threshold. In one embodiment, the system may perform the operations of communicating with a positioning device relating to an order of the plurality of orders; and identifying the order location relating to the order. In another embodiment, the system may perform, by or on the at least one processor, the operations of receiving at least one order from a network. In a further embodiment, the system may perform, by or on the at least one processor, the operation of identifying the marked locus based on at least one cluster algorithm. Exemplary cluster algorithm is described elsewhere in the present teachings. In still another embodiment, the system may perform, by or on the at least one processor, identifying a second number of providers relating to the marked locus. The second number of providers may share a second characteristic. The second characteristic may be that a distance between the first location and a location relating to a provider of the second number of providers is less than a second threshold. In one embodiment, the first characteristic (that the distance between the first location and a location relating to an order of the first number of orders is less than a first threshold) and the second characteristic may be the same, and the first threshold and the second threshold may be the same. The first number of orders and the second number of providers may be located in the same locus or region. The marking the locus may including determining the ratio of the first number to that second number. For instance, the locus is marked when the ratio of the first number to the second number exceeds a third threshold. In an embodiment, the marking the locus includes determining that the first number, or the second number exceeds a fourth threshold. In an embodiment, the marking the locus includes determining that the first number, or the second number exceeds a fourth threshold. In an embodiment, the system may perform, by or on the at least one processor, the operations of identifying an area as a locus, and/or marking the locus such that the information relating to the marked locus is delivered to one or more requesters, one or more providers, or the like, or a combination thereof. The criteria for identifying a locus may be the same as the criteria for marking a locus. In another embodiment, an area may be identified based on a first criterion (or criteria), and the identified locus that satisfies a second criterion (or criteria) is marked such that the information relating to the marked locus is delivered to one or more requesters, one or more providers, or the like, or a combination thereof. The first criterion (or criteria) may be different from the second criterion (or criteria). The system may perform, by or on the at least one processor, the operation of delivering the information relating to the marked locus to a requester relating to an order of the marked locus, or to the at least one provider. The delivering may be performed by a device outside of, or independent from the system.
In a further example, a method implemented on at least one processor is provided. The method includes receiving, by or on the at least one processor, a plurality of orders for a service; marking, by or on the at least one processor, a locus based on the plurality of orders, the marked locus relating to a first number of orders of the plurality of orders, the first number of orders sharing a first characteristic, and the marked locus relating to a first location; and identifying, by the at least one processor, at least one provider of the service to whom information relating to the marked locus is to be delivered. The method may include identifying an area as a locus, and/or marking the locus such that the information relating to the marked locus is delivered to one or more requesters, one or more providers, or the like, or a combination thereof. The criteria for identifying a locus may be the same as the criteria for marking a locus. In another embodiment, an area may be identified based on a first criterion (or criteria), and the identified locus that satisfies a second criterion (or criteria) is marked such that the information relating to the marked locus is delivered to one or more requesters, one or more providers, or the like, or a combination thereof. The first criterion (or criteria) may be different from the second criterion (or criteria). The method may include delivering the information relating to the marked locus to a requester relating to an order of the marked locus, or to the at least one provider, or the like, or a combination. The method is adapted for managing supply of the service.
In still a further example, a method implemented on at least one processor is provided. The method includes receiving a first order and a second order, the first order comprising a first order time, a first origin, and a destination, the second order comprising a second order time and a second origin; calculating a first time to reach the destination based on the first order time, the first origin, and the destination; determining a first difference between the destination and the second origin; determining a second difference between the first time and the second order time; and marking, if the first difference is less than a first threshold and the second difference is less than a second threshold, the first order and the second order. The method is adapted for managing the first order and the second order.
Any one of the thresholds described above may be a constant, or a variable. Merely by way of example, a threshold may vary based on, e.g., the time of the day, the day of the week, the road condition, the traffic condition, a specific condition specified by a requester or a provider, or the like, or a combination thereof. A threshold may be a predetermined constant or a predetermined variable. For instance, the threshold may be a variable as a function of time, a function of a contingent condition, or a function of two or more parameters, or the like. The function may be derived from, e.g., historical information using a machine-learning algorithm. An exemplary machine learning algorithm may be one of supervised learning, unsupervised learning, semi-supervised learning, reinforcement learning, or the like, or a combination thereof. An exemplary machine learning algorithm may be c4.5, k-Means, Support Vector Machines (SVM), Apriori, Expectation Maximization (EM), PageRank, AdaBoost, k-Nearest Neighbors (kNN), Naive Bayes, Classification and Regression Tree (CART), or the like, or a combination thereof.

The features of the present teachings may be realized and attained by practice or use of various aspects of the methodologies, instrumentalities and combinations set forth in the detailed examples discussed below.
The methods, systems, and/or programming described herein are further described in terms of exemplary embodiments. These exemplary embodiments are described in detail with reference to the drawings. These embodiments are non-limiting exemplary embodiments, in which like reference numerals represent similar structures throughout the several views of the drawings, and wherein:
In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. However, it should be apparent to those skilled in the art that the present teachings may be practiced without such details. In other instances, well known methods, procedures, systems, components, and/or circuitry have been described at a relatively high level, without detail, in order to avoid unnecessarily obscuring aspects of the present teachings.
The present teachings describe method, system, and programming aspects of a service system to provide service information which identifies areas that are under-served or over-served by service providers. The method and system as disclosed herein aim at identifying the distribution pattern of, e.g., orders, service providers, or the like, or a combination thereof, and mark an area or region where there is a mismatch between the demand and supply of a service, and provide such information to service requesters, service providers, or the like, or a combination thereof. The regions of interest may be identified based on various algorithms or other criteria in different situations with real time and/or historic information, or other information. The efficiency of the service may be improved as service providers or requesters may make adjustments, e.g., moving to different regions or areas to get or provide service, based on this information.
The system and method for managing supply of service may be used in different transportation system (transportation includes but is not limited to land transportation, sea transportation and air transportation, or the like, or a combination there of) including, such as fleet management system employed for taxi and limousine fleets, intra-city express delivery system, or the like. It is understood that these exemplary applications of the system and method disclosed herein are provided for illustration purposes, and not intended to limit the scope of the present teachings. The disclosed system and method may be applied in other contexts, e.g., other on-demand services.
In the present teachings, a “user,” a “passenger,” a “requester,” a “service requester,” and a “customer” are used interchangeably to refer to individuals that are requesting or ordering a service. Also, a “provider,” a “service provider,” and a “supplier” are used interchangeably to refer to an individual, an entity or a tool that may provide a service or facilitate the providing of the service. Also, a “locus,” a “cluster,” and a “group” are used interchangeably to refer to a group of similar objects sharing a certain characteristic. In some embodiment, a “locus” or a “cluster” may relate to a certain region. Merely by way of example, a locus may refer to a plurality of orders in a region, and may also refer to the region. In some embodiment, a region may relate to a plurality of objects that may be seen as a locus or a cluster.
The users 104 from whom orders for services may be placed may be of different types, such as users connected to the network 114 via a desktop computer 104-1, a laptop computer 104-2, a built-in device in a motor vehicle 104-3, or a mobile device 104-4. A user or requester may send a request and receive results or suggestions via the network 114. The scheduling system (or referred to as system) 102 may access information stored in the User Log DB (Database) 106 or directly via the network 114.
The User Log DB 106 may be generated by one or more different applications (not shown), which may be running at the backend of the scheduling system, or as a completely standalone system capable of connecting to the network 114, accessing information from different sources, analyzing the information, generating structured information, and storing such generated information. As illustrated in
It should be noted that it is possible to implement a different system 102 having more or fewer constituent modules than those of
In some embodiments, the information relating to an identified or marked locus may be delivered to one or more service providers, and/or one or more service requesters, or one or more third party, as illustrated in
While the foregoing has described what are considered to constitute the present teachings and/or other examples, it is understood that various modifications may be made thereto and that the subject matter disclosed herein may be implemented in various forms and examples, and that the teachings may be applied in numerous applications, only some of which have been described herein. Those skilled in the art will recognize that present teachings are amenable to a variety of modifications and/or enhancements.
The historical information unit 410 may be configured to receive historical information from, e.g., the user log DB 106 and/or from at least one third party (e.g., service center, etc.). In an embodiment, the historical information unit 410 further includes a historical information DB 250 used for storing and/or processing historical information. As described, historical (or historic) information may include past information relating to, e.g., the demand or supply of a service (including same or similar services) in an area or region and/or over a period of time. The historical information may include, but is not limited to, past and/or recent information, such as the number of requesters in an area or region at a certain time or over a period of time, the time an order was placed, the number of orders, the locations and/or times for pickup by taxis, the extra expense or tip a service requester was willing to pay, special conditions requested in an order (e.g., a lot of luggage, a lot of passengers, a specific type of vehicle, etc.), the requesters' information stored in the user log DB 106 and/or historical information DB 250, the gender, age, driving years or experience of a provider, vehicle age, vehicle type, license plate number, the extra service capacity (e.g., extra features of the vehicle), order number, number of accepted orders, order acceptance rate, requesters' habits, the taxis' location and so on. The historical information may be collected and stored in one or more databases, such as through cloud data storage or locally on a server or computer. The historical information may also come from at least one entity or organization which is, but is not limited to, a commission by government and/or enterprises.
The order information unit 420 may be configured to receive one or more orders from, e.g., requesters and/or from a third party via, e.g., an application or a portal (e.g., a terminal that is configured to communicate with, by way of sending information to and/or receiving information from, the scheduling system via a network). Such an application or portal may be installed on a device, e.g., a smart phone, a desktop, a laptop, or a device described elsewhere in the present teachings or known to those of ordinary skill in the art. Merely by way of example, a third party may make an order for a service on behalf of a passenger or a group of passengers using such an application. The order may include information regarding, e.g., the time an order is placed, the number of taxis, the location for pickup (or origin), the destination, the time for pickup, the contact information, the number of passengers, the number of luggage pieces, the tip that requesters are willing to pay, additional conditions requested relating to the order, whether a driver is needed or not (e.g., the service requester will drive himself or has a driver), or the like, or a combination thereof.
The provider information unit 430 may be configured to receive provider information from, e.g., providers and/or from a third party via, e.g., an application or a portal as described above. The provider information may include, but is not limited to, information specific to a provider and/or a taxi, such as gender, age, driving years or experience of a provider, the number of accepted orders, the order acceptance rate at specific times or over periods of time, the vehicle age, the vehicle type, the capacity of the vehicle, the license plate number, the taxi's location, extra service capacity (e.g., extra features of the vehicle), whether the vehicle is available for use without providing a driver (e.g., the service requester himself will have to drive the vehicle or arrange a driver), or the like, or a combination thereof.
The contingent information unit 440 may be configured to receive contingent information from one or more sources, including, e.g., official news systems (e.g., a weather report system, a real time road conditions system, a broadcast station, etc.) and/or from at least one third party via, e.g., an interface, a portal, an application (e.g., 3D realistic scene by Google map, etc.), or the like, or a combination thereof. In an embodiment, the contingent information includes a contingent information source 260. The contingent information includes, but is not limited to, the information from the contingent information source 260, such as a traffic condition relating to an order or an order locus, the road condition relating to an order or an order locus, the weather condition relating to an order or an order locus, or the like, or a combination thereof. For example, when the weather is rainy, the contingent information unit 440 may receive the “Rainy” information from the contingent information source 260 that may be connected to, e.g., a real time weather forecast system, then the information may be processed or forwarded to another portion of the scheduling system 102, e.g., to the identification module 220.
The location information collector 510 may be configured to collect location information from, e.g., a requester or a device associated with the requester, a provider or a device associated with the provider, a third party or a device associated with the third party, or the like. For example, the location information may include the location for pickup, the destination to go, etc.
The miscellaneous information collector 520 may be configured to collect information from requesters and/or from at least one third party accessible application. Miscellaneous information may include information relating to an order (e.g., the time constraint, the number of passengers, the number of luggage pieces, the size of luggage, the location and/or the time of the pickup, the destination, the amount of tip the requester is willing to pay, a passenger's habits or preferences, or the like, or a combination thereof), information relating to a provider (e.g., gender, age, driving years or experience, the vehicle age, the vehicle type, the license plate number, extra service capacity (e.g., extra features of the vehicle), the order number, the number of accepted orders, the order acceptance rate at specific times or over periods of time, the taxis' locations, whether the vehicle is available for self-driving), other input information from a passenger, a provider, or a third party, or the like, or a combination thereof. Miscellaneous information may also include contingent information relating to an order or a locus.
In an embodiment, the receiver 610 may be configured to communicate with one or more positioning devices for receiving location information or location signal. A position device may be, e.g., a smart phone, a global positioning system, a desktop, a laptop, a tablet computer, an in-vehicle computing platform, a cloud computing based portable user platform with location determined services, a personal digital assistant (PDA), a netbook, an ultrabook, a digital photo frame, a media player, a handled gaming console, an ebook reader (e.g., Amazon kindle voyage, etc.), a global navigation satellite system (GLONASS), a Beidou navigation system (BDNS), a Galilio positioning system, a quasi-zenith satellite system (QZSS), a base station (BS), a wearable computing device (e.g., eyeglasses, wrist watch, etc.), a virtual display device, a display enhanced device, a car PC, a car navigation, a radar chronograph, a laser velocimeter, or the like, or a combination thereof. A positioning device may emit or receive a positioning signal that may be used to determine the location of the positioning device or a user of the device. The location information processor 620 may be configured to receive the input regarding location information or identify the location of the received information, such that the geographic or location information (e.g., longitude, latitude, altitude, address, or the like, or a combination thereof) of a requester, a provider, or the like, may be determined. The input regarding location information includes, but is not limited to, location information from a requester, a provider, and/or at least one third party. For example, a requester inputs a location where his/her friend, a passenger, needs to be picked up for a taxi ride, when the passenger doesn't have a device with the positioning function. It is understood that various modifications may be made thereto and that the subject matter disclosed herein may be implemented in various forms and examples, and that the teachings may be applied in numerous applications, only some of which have been described herein. Those skilled in the art will recognize that present teachings are amenable to a variety of modifications and/or enhancements. As used herein, a “taxi” is intended to refer to any means of transportation used to convey passengers or items in return for payment or fare, including but not limited to street taxis that pick up passengers on the street, livery vehicles that respond to prearranged trips, limousines, and delivery services.
In one embodiment, the identification module 220 may be configured to receive information from the collection module 210 and output calculation results. The information from the collection module 220 may include but without limiting to historical information, order information, provider information, contingent information, or the like, or a combination thereof. As shown in
The module calculation control unit 802 may be configured to communicate with the module calculation configurations 804, to receive information from, e.g., the collection module 210, and send the received information for further process in one or more of the historical information processor 806, the order information processor 808, the provider information processor 810, and the contingent information processor 812, or the like, or a combination thereof. The module calculation control unit 802 may control the mode of calculation to be performed, according to instructions retrieved from the module calculation configurations 804. The module calculation configurations 804 may include the instructions regarding calculation to be performed in module calculation control unit 802, historical information processor 806, order information processor 808, provider information processor 810, contingent information processor 812, and module integration controller 814. Merely by way of example, instructions retrieved from the module calculation configurations 804 may determine whether any one of the historical information processor 806, the order information processor 808, the provider information processor 810, and the contingent information processor 812 is involved in a calculation; the calculation sequence between the historical information processor 806, order information processor 808, and provider information processor 810;an algorithm in any one of the historical information processor 806, order information processor 808, provider information processor 810, and contingent information processor 812 to be used; the algorithm-related parameters in any one of the historical information processor 806, order information processor 808, provider information processor 810, and contingent information processor 812; how the intermediate results from any one of the historical information processor 806, the order information processor 808, the provider information processor 810, and the contingent information processor 812 are to be integrated, or the like, or a combination thereof. The instructions may be retrieved from the module calculation configurations 804 by the module calculation control unit 802 based on, e.g., the information received by the collection module 210, including information regarding an order or locus, a provider, a contingent condition, historical information, an instruction regarding the calculation to be performed or algorithm to be used provided by a requester, a provider, a third party, or automatically selected by the system. Merely by way of example, if no historical information is received in connection with a locus, the historical information processor is bypassed in the calculation. As another example, if a requester specifies that a criterion in connection with an order (e.g., a time constraint, a tip to be provided, etc.), a specific algorithm may be retrieved from the module calculation configurations 804 by the module calculation control unit 802 and used to process relevant information. As another example, if a demand/supply is determined based on a historic number of orders in a certain region over a period of time and real time information of the number of providers in the region, the historical information processor and provider information processor both may be involved in processing the information.
The historical information processor 806 may be configured to process historical information. The order information processor 808 may be configured to process order information relating to an order or a locus. The provider information processor 810 may be configured to process information relating to a provider. The contingent information processor 812 may be configured to process contingent information relating to an order or a locus. The historical information processor 806, the order information processor 808, the provider information processor 810, and the contingent information processor 812 each may be an independent computing unit. In another example, at least two of the historical information processor 806, the order information processor 808, the provider information processor 810, and the contingent information processor 812 may share a computing unit with another.
Returning to
The module integration controller 814 may be configured to integrate the received or processed data (or intermediate results) and calculate a result based on, the instructions retrieved from the module calculation configurations 804 by the module calculation control unit 802. The module integration controller 814 may be an independent computing unit or a shared computing unit with historical information processor 806, order information processor 808, provider information processor 810, and contingent information processor 812.
The connection type between module calculation control unit 802, module calculation configurations 804, historical information processor 806, order information processor 808, provider information processor 810, contingent information processor 812, and module integration controller 814 may be wired or wireless, all integrated in a circuit or partially integrated in a circuit or distributed in different places.
The identification module 220 may process a plurality of orders, and may identify or mark at least one locus based on various information. The various information may include information relating to orders, requesters, passengers, providers, contingent information, historical information, a certain region or area, or geographic information of a certain region or area, or the like, or a combination thereof. For example, the identification of a locus or region may be based on order distribution by clustering algorithms, or based on region conditions. A locus may include an order set including one or more orders. The orders in the locus are more similar to each other than to those outside of the locus. The orders in the locus share at least one characteristic. Merely by way of example, a shared characteristic may be that a distance between a location relating to the locus (e.g., a reference point or a location within the locus) and a location relating to an order of is less than a threshold. The threshold may be a constant, or a variable. Merely by way of example, the threshold may vary based on, e.g., the time of the day, the day of the week, the road condition, the traffic condition, a specific condition specified by a requester or a provider, or the like, or a combination thereof. The threshold may be a predetermined constant or a predetermined variable. For instance, the threshold may be a variable as a function of time, a function of a contingent condition, or a function of two or more parameters, or the like. The function may be derived from, e.g., historical information using a machine-learning algorithm. Exemplary machine learning algorithm is described elsewhere in the present teachings.

gridCy=(int)((latitude−leftLatitude)/width)
It shall be noted that the identification of loci or regions shall not be restricted by the examples described above since they are simply specific embodiments of the present teachings. Those having ordinary skills in the art will recognize that the present teachings are amendable to a variety of modifications and/or enhancements. For example, the division of regions in
Information used in the identification module 220 may be stored in one or more storage devices (not shown in figures) inside the scheduling system 102 or outside of the scheduling system 102 (e.g., in a storage provided by a vendor). In some embodiments, the identification module 220 may be configured to receive, e.g., historical information, order information, provider information, contingent information, or the like, or a combination thereof. Such information may be from the collection module 210. The identification module 220 may be configured to identify at least one locus based on the received information and an algorithm. In an embodiment, the region partition algorithm may partition an area (e.g., a city, a district, etc.) into at least one region according to, but not limited to, longitude and latitude, coordinate, position, size of the area, density, and/or grid, as illustrated in
Merely by way of example, the Dbscan clustering algorithm includes the following steps:
Step 1, at block 1301, detecting order p in order set D; at decision block 1302, determining whether the order p in order set D is processed. If order p is grouped under one certain locus or is marked as noise, which means p is processed, then returning to block 1301, detecting the next order in D. If order p is not processed, then proceeding to block 1303, adding all the orders in order p's r region (if the distance between the latitude and longitude of starting location of one certain order and the latitude and longitude of starting location of order p is less than radius r, the order is considered as an order in order p's r region) to candidate set N.
Step 2, at block 1304, detecting the number of orders in candidate set N, at decision block 1305, determining whether the number of orders of order set N is less than e. If the number of orders in order set N is less than e, proceeding to block 1306, marking order p as noise, then returning to block 1301, and detecting the next order in D. If the number of orders in order set N is equal to or more than e, then proceeding to block 1307, creating a new locus C and adding order p to locus C.
Step 3, at block 1308, detecting order p′ in candidate set N, at decision block 1309, determining whether the order p′ in N is processed. If order p′ is grouped under one certain locus or is marked as noise, which means p′ is processed, then returning to block 1308, detecting the next order in N. If order p′ is not processed, then proceeding to block 1310, adding all the orders in order p's r region to candidate set N′. At block 1311, detecting the number of orders of order set N′; at decision block 1312, determining whether the number of orders of order set N′ is less than e. If the number of orders of order set N′ is equal to or more than e, then proceeding to block 1313, adding orders N′ to N; at decision block 1314, determining whether p is grouped under any locus. If order p′ is not grouped under any locus, then proceeding to block 1315, adding order p′ to locus C.
Step 4, at decision block 1316, determining whether order set N is all detected. If N is not all detected, then returning to block 1308, detecting next order in N, repeating step 3, until order set N is all detected. If N is all detected, then proceeding to decision block 1317.
Step 5, at decision block 1318, determining whether order set D is all detected. If D is not all detected, then returning to block 1301, detecting next order in D, repeating step 1-3, until order set D is all detected. If D is all detected, then proceeding to END.
Thus, after Dbscan algorithm clustering, outputting a plurality of loci, each of which may include orders relating to a certain location.
Dbscan clustering algorithm pseudo-code may be described as follows:
The ExpandCluster algorithm pseudo-code may be described as follows:
Furthermore, based on the orders in a locus, parameters including, e.g., the locus center, the radius, the number of providers, the number of orders in the locus, or the like, or a combination thereof, may be calculated.
Merely by way of example, based on the latitude and longitude of all the orders in the locus, the latitude and longitude of the locus center may be calculated using mean value. After obtaining latitude and longitude of the locus center, the distance between the latitude and longitude of the locus center and latitude and longitude of each order in the locus may be calculated, and the maximum value of the distance maybe taken as the radius of the region. The number of orders in the region is the total number of all the orders in the locus. Number of providers in the region is determined as: calculating the distance between latitude and longitude of the locus center and each providers, and counting the number of the providers whose distance are less than the radius of the region.
Thus, one or more order loci may be identified in a certain area (e.g., in a certain city), for example, locus 1 is described with center coordinate xy (latitude and longitude of the locus center), radius r, number of orders n, number of providers m; locus 2 is described by center coordinate xy′, radius r′, number of orders n′, number of providers m′, etc.
Based on the order information in one certain order locus, the identification module 220 may be configured to calculate, e.g., the number of orders in the order locus, the location (by way of, e.g., latitude and longitude) of the locus center, radius of the locus, or the like, or a combination thereof. As used herein, the number of orders in the locus is the total number of orders in the order locus; the latitude and longitude of the locus center is the average value of all the latitude and longitude of the locus; and the radius of the locus is the maximum value of the distance between the latitude and longitude of the locus center and latitude and longitude of starting location of each order in the order locus. There are other ways to define the location of the locus center. The description provided above is for illustration purposes, and is not intended to limit the scope of the present teachings. The orders in the locus may be closer to each other than orders outside of the locus. A locus so identified may have a concentration of orders for a service (or the same or similar services).
In one embodiment, the identification module 220 may be configured to further mark an identified locus if the locus meets a certain criterion indicating a mismatch of the demand for service within the identified locus and the supply of the service within the identified locus. The determination may be made based on, e.g., the information received from the collection module 210, or information processed by the historical information processor 806, the order information processor 808, provider information processor 810, and/or contingent information processor 812. The information may include historical information, order information, provider information, or contingent information, or the like, or a combination thereof. For example, the information may include that relating to the identified locus, including e.g., an order location, a provider location, an order acceptance rate, an order acceptance rate, a traffic condition, a road condition, a weather condition, and historical information, or the like, or a combination thereof. In an embodiment, a provider-requester ratio and the order acceptance rate relating to the identified locus are calculated. In one example, an identified locus that meets a certain criterion is further marked as an “under-served” locus, where more service providers are needed. In another example, a provider-requester ratio, a factor relating to the road condition, a factor relating to the traffic condition are calculated. Based on the calculated parameter(s), an identified locus that meets a criterion is further marked as “under-served” locus.
Those having ordinary skills in the art will recognize that the present teachings are amendable to a variety of modifications and/or enhancements. For example, at least one parameter is necessary in the module to determine whether a locus shall be further marked. In some embodiments, more than two parameters shall also be implementable to further mark a locus.
The determination module 230 may be configured to determine to whom the information relating to a marked locus is to be delivered. As illustrated in
In one embodiment, the delivery module may be configured to deliver the information relating to the marked locus to various recipients including, e.g., providers around marked loci. At block 1504, information relating to the marked locus (e.g., in the form of advertisement or notification) is delivered to the providers that satisfy the first condition. According to an embodiment of the present teachings, the advertisement to schedule or encourage providers from an outside region to the marked locus may be realized by several methods or any combination of them. For example, information delivered to one or more providers from a region outside of a locus may include at least one piece of information selected from, e.g., the number of shortage in providers in a locus in a period of time, a locus marked as over-served or under-served, the distance between the provider's position and a marked locus, an estimated time for the provider to reach the marked locus or an order within the locus, a route (e.g., a faster route, a route without toll, etc.) that the provider may use to reach the marked locus or an order within the locus, a suggested route, or the like, or a combination thereof. For inconvenient traffic area, traffic information may be delivered to the providers. Alternative information, such as road administration reconstructive area, may also be delivered to the providers to indicate the road condition. In another example, the advertisement may be a distribution diagram showing the density distribution of providers/passengers with different colors or whatever distinguishable patterns. In another example, the advertisement may be accompanied by changing the pricing standard for service in the marked locus, and the pricing standard may also be sent to requesters so that requesters and providers may reach an agreement in advance. In one embodiment, some information relating to the marked locus is delivered to a requester within the locus. Merely by way of example, if an adjacent region has more providers than where the requester is, this information may be delivered to the requester. The requester may also receive information regarding a fast route to get to the adjacent area, the distance that the requester needs to travel, the road condition, the traffic condition, or the like, or a combination thereof. Information delivered to one or more providers, one or more requesters, etc., may be delivered in the format of, e.g., a text message, a voice message, graphic information that may be displayed on a screen, an animation, or the like, or a combination thereof. The recipient of the information, e.g., a provider, a requester, etc., may specify the content of the information to be delivered, the format the information may be presented, the device to which such information is to be delivered, or the like, or a combination thereof.
Those skilled in the art will recognize that present teachings are amenable to a variety of modifications and/or enhancements. For example, the information of a service provider maybe received before the information relating to a marked locus being received, or the two set of information maybe received simultaneously or essentially simultaneously. In another example, the information relating to a marked locus may be delivered if two or more conditions are met. For example, a first condition may be if the distance between the provider and any locus region center (or locus center) is more than the radius of the locus (indicating that the provider is not in any of the loci). A second condition may be if the distance between the provider and the nearest locus is on the interval (R, R+D) (which means the distance is equal to or more than R, while equal to or less than R+D), wherein R is a parameter based on the radius of the loci, D is an variable or invariable determined by the system.
In another embodiment according to the present teachings, the delivery module may deliver advertisement to service requesters. For example, provided that loci are marked to be advertised, in case of a contingent happens, such as a traffic jam in a locus, a change in weather condition, or an end of an activity in a locus, the system may deliver advertisement or guidance information to requesters to conduct requesters in the specific locus to a different region that may be easier to get a vehicle service. According to the embodiment of the present teachings, the traffic jam condition may be determined by satellite views or vehicle density of the road monitor. Moreover, in the case of a road closing for maintenance, advertisement or guidance information may be delivered to requesters.
To implement various modules, units, and their functionalities described in the present disclosure, computer hardware platforms may be used as the hardware platform(s) for one or more of the elements described herein (e.g., the scheduling system 102, and/or other components of the system 100 described with respect to
The computer 1800, for example, includes COM ports 1850 connected to and from a network connected thereto to facilitate data communications. The computer 1800 also includes a central processing unit (CPU) 1820, in the form of one or more processors, for executing program instructions. The exemplary computer platform includes an internal communication bus 1810, program storage and data storage of different forms, e.g., disk 1870, read only memory (ROM) 1830, or random access memory (RAM) 1840, for various data files to be processed and/or communicated by the computer, as well as possibly program instructions to be executed by the CPU. The computer 1800 also includes an I/O component 1860, supporting input/output flows between the computer and other components therein such as user interface elements 1880. The computer 1800 may also receive programming and data via network communications.
Hence, aspects of the methods of the management of supply of service and/or other processes, as outlined above, may be embodied in programming. Program aspects of the technology may be thought of as “products” or “articles of manufacture” typically in the form of executable code and/or associated data that is carried on or embodied in a type of machine readable medium. Tangible non-transitory “storage” type media include any or all of the memory or other storage for the computers, processors, or the like, or associated modules thereof, such as various semiconductor memories, tape drives, disk drives and the like, which may provide storage at any time for the software programming.
All or portions of the software may at times be communicated through a network such as the Internet or various other telecommunication networks. Such communications, for example, may enable loading of the software from one computer or processor into another, for example, from a management server or host computer of a scheduling system into the hardware platform(s) of a computing environment or other system implementing a computing environment or similar functionalities in connection with the management of supply of service. Thus, another type of media that may bear the software elements includes optical, electrical and electromagnetic waves, such as used across physical interfaces between local devices, through wired and optical landline networks and over various air-links. The physical elements that carry such waves, such as wired or wireless links, optical links or the like, also may be considered as media bearing the software. As used herein, unless restricted to tangible “storage” media, terms such as computer or machine “readable medium” refer to any medium that participates in providing instructions to a processor for execution.
Hence, a machine-readable medium may take many forms, including but not limited to, a tangible storage medium, a carrier wave medium or physical transmission medium. Non-volatile storage media include, for example, optical or magnetic disks, such as any of the storage devices in any computer(s) or the like, which may be used to implement the system or any of its components as shown in the drawings. Volatile storage media include dynamic memory, such as a main memory of such a computer platform. Tangible transmission media include coaxial cables; copper wire and fiber optics, including the wires that form a bus within a computer system. Carrier-wave transmission media may take the form of electric or electromagnetic signals, or acoustic or light waves such as those generated during radio frequency (RF) and infrared (IR) data communications. Common forms of computer-readable media therefore include for example: a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, DVD or DVD-ROM, any other optical medium, punch cards paper tape, any other physical storage medium with patterns of holes, a RAM, a PROM and EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave transporting data or instructions, cables or links transporting such a carrier wave, or any other medium from which a computer may read programming code and/or data. Many of these forms of computer readable media may be involved in carrying one or more sequences of one or more instructions to a physical processor for execution.
Those skilled in the art will recognize that the present teachings are amenable to a variety of modifications and/or enhancements. For example, although the implementation of various components described above may be embodied in a hardware device, it may also be implemented as a software only solution—e.g., an installation on an existing server. In addition, the scheduling system for management of supply of service as disclosed herein may be implemented as a firmware, firmware/software combination, firmware/hardware combination, or a hardware/firmware/software combination.
The following examples are provided for illustration purposes, and are not intended to limit the scope of the present teachings.
Using Beijing as an example, vehicle demands from a suburban area during the morning rush-hours are much more than those from an area around the city center. For example, there is a great demand for taxi services in the Huilongguan area from 8:00 am to 9:00 am; during the evening rush-hour, for example from 18:00 pm to 19:00 pm, there is a great demand for taxi services in the Zhongguancun area.
At the server (or a scheduling system) of taxi booking software or call center, a great number of booking orders collected from passengers are stored. In general, the format of the booking orders collected from passengers is as follows in Table 1:
Normally, once a passenger makes an order for a taxi, an order information in an entry in Table 1 may be sent to the server.
The server (or a scheduling system), according to the starting location of the orders, performs a statistical analysis (e.g., using the Dbscan clustering algorithm) on the orders in a certain area (e.g., Beijing) during a certain time period (from 18:00 pm to 18:05 pm in the same day), and identifies a plurality of loci(region1: around Zhongguancun area, 2.5 km radius, number of passengers: 200; region2: around Shangdi, 3.4 km radius, number of passengers: 300; . . . ).
Each taxi reports its latitude and longitude information every 10 seconds by an application the taxi driver uses. An exemplary format of the information is as follows in Table 2:
After selecting appropriate locus, the server (or the scheduling system) may deliver information “Hello Mr., X km from you, a great number of passengers demand vehicle in XXX” to one or more taxi drivers (providers).
A scheduling system identifies a plurality of loci utilizing Dbscan clustering algorithm based on the vehicle demands distribution of Shanghai. The scheduling system also calculates the number of orders, the location (by way of, e.g., the latitude and longitude) of the locus center, the locus radius, the number of providers, and the number of orders accepted, the order acceptance rate, the provider-requester ratio in a locus, based on, e.g., the order information and the provider information in the locus.
The order information may include: order numbers, starting locations (by way of, e.g., the latitude and longitude), starting times, whether an order has been accepted, or the like, or a combination thereof; the taxi information may include: driver numbers (IDs), report times, the location (by way of, e.g., longitude and latitude) of providers. The number of orders in the locus may be the total number of orders in the locus. The latitude and longitude of the locus center may be the average value of the latitude and longitude of all the orders in the locus. The radius of the locus may be the maximum distance between the locus center and of the location relating to an order in the locus. The number of providers in the locus may be the total number of the providers whose distance between the locus center and the location of their taxi is less than the radius of the locus. The number of orders accepted may be the total number of orders accepted in the locus. The order acceptance rate may be the ratio of the number of orders accepted and the number of all the orders in the locus. The provider-requester ratio may be the ratio of the number of providers to the number of the orders in the locus.
In an exemplary scenario, the number of providers, the number of orders, order acceptance rate, provider-requester ratio are listed as follows in Table 3:
From the data, it may be concluded that as the increasing of provider-requester ratio, the order acceptance rate significantly increases. Referring to
A mismatch of the supply-demand in the locus may be indicated by the order acceptance rate and the provider-requester ratio.
In some embodiments, if the order acceptance rate in one certain locus is above 80%, the locus may be considered healthy (i.e. the demand-supply relationship may be considered healthy in the locus); if the order acceptance rate in one certain locus is under 80%, the locus may be considered unhealthy (i.e. the demand-supply relationship may be considered unhealthy in the locus). As to a locus whose order acceptance rate is under 80%, if the provider-requester ratio (divide the number of providers by the number of orders) is under 10, the provider-requester ratio may be considered low. One reason for the low order acceptance rate may be that the number of providers are insufficient to satisfy orders for service in the locus. It may be beneficial to encourage providers from adjacent regions to enter and service the locus. This may be facilitated by delivering information relating to the locus to providers in the adjacent regions. As to a locus whose order acceptance rate is under 80%, if the provider-requester ratio is above 10, the reason for the low order acceptance rate may be something other than a low provider-requester ratio, and it may be unbeneficial to encourage providers from adjacent regions to enter and service the locus.
In summary, a locus with low order acceptance rate and low provider-requester ratio may have a mismatch between the supply and demand. It is presented in Table 4:
These 3 vehicle demand dense loci illustrated in Table 4 may be considered as critically unhealthy (imbalanced of supply and demands), and providers may be encouraged to enter and service the loci. This may be facilitated by delivering information relating to the loci to providers, e.g., those in the adjacent regions.
