Transporting goods between two points often involves tradeoffs. As an example, the cost of transport and the speed with which an item is transported are frequently inversely proportional—faster transportation costs more and less expensive transportation can be slower. In some applications, it is very important that one of these aspects is optimized. For instance, an organ for transplant might need to reach its destination as fast as possible no matter the cost. Conversely, for other items, minimization of the transportation cost might be the most important criterion.
Historically, such optimizations were accomplished largely on an ad hoc basis requiring significant user input and time to accomplish. Additionally, the historical methods were often based on incomplete information, so sub-optimal solutions were reached. In view of the increasing demand for logistical optimization, better solutions are needed.
Systems and methods of performing logistical management are provided. According to embodiments, a management system may include an interface coupled to an electronic data store and one or more processors coupled to the interface. The one or more processors can be configured to receive a request to ship a package from an electronic device associated with a user. The request can include an initial location and information relating to one or more characteristics of the package. In response to receiving the request, the one or more processors may query the electronic data store to determine a set of possible itineraries for the package. The set of possible itineraries can then be validated against a set of pre-determined rules to produce a subset of itineraries. One of the subset of itineraries can then be chosen.
According to embodiments, the one or more processors may select the itinerary by first sorting the subset of possible itineraries according to a criterion, and then selecting the itinerary that is the highest ranking according to the criterion. The criterion my include one or more of a cost, a distance, a duration of the itinerary, a total number of segments, and a risk associated with the itinerary. Additionally, in some embodiments, the one or more processors may select the itinerary by presenting a subset of itineraries to a user device and receiving a response indicating a selection from among the subset of itineraries.
In some embodiments, the one or more processors are further configured to consider one or more characteristics of the package. For instance, the characteristics of the package may comprise a weight, a volume, a hazard level, a content, a durability, a shape, dimension measurements, a fragility of the package, and a density. In some embodiments, itineraries that are incompatible with one of the characteristics can be also be eliminated from the set of itineraries. Additionally, itineraries that are temporally infeasible can be eliminated.
In some embodiments, each of the itineraries comprises a plurality of itinerary segments. In such embodiments, the one or more processors may be configured to receive a plurality of itinerary segments from the electronic data store and to construct the set of possible itineraries from the plurality of itinerary segments. Additionally, the one or more processors can be configured to eliminate itinerary segments from the plurality of itinerary segments based on a compatibility of that segment with a characteristic of the package. Additionally the various segments may rely on different modes of transportation (e.g., ground, air, rail, etc.)
Additional systems and methods relating to logistical computer systems are provided. According to one such embodiment, a logistical computer system may comprise a network interface coupled to an electronic network and one or more processors coupled to the network interface. The one or more processors may be configured to initiate a trip for a package between a first location and a second location. The user associated with a mobile device may be selected to transport the package between the first location and the second location. Scan information relating to the package at the first location may be received from the mobile device via the electronic network. Additionally, scan information relating to the package the second location may be received from the mobile device via the electronic network.
According to some embodiments, the user associated with the electronic device may be selected based on a certification associated with the user. Furthermore, the one or more processors can be configured to select the user by transmitting a notification indicating that the trip is available to a plurality of electronic devices that are each associated with a user and receiving an acceptance from one of the plurality of electronic devices.
In some embodiments, the one or more processors may generate a transit document based on information associated with the package and transmit an electronic representation of the transit document to the electronic device associated with the user. Additionally and/or alternatively, the one or more processors may optionally transmit the transit document to a transit provider (e.g., a cargo air carrier). According to some embodiments, the representation of the transit document may comprise a graphical representation of, for instance, an airway bill for a particular transit provider (e.g., an airline company).
According to some embodiments, the one or more processors may be configured to detect an error in the first scan information. If or when this occurs, the one or more processors may be configured to assign new scan information to the package.
According to various embodiments, the one or more processors may be configured to generate route information for a trip associated with transporting the package. This route information may be transmitted to the electronic device via the electronic network. Additionally, if a change in the itinerary is received, the one or more processors are optionally further configured to receive, generate, and transmit updated route information to the electronic device based on the received change in the itinerary. Additionally, a graphical representation of the trip progress (e.g., a map) can be generated and transmitted to one or more electronic devices associated with a customer.

The boundaries of these functional building blocks have been arbitrarily defined herein for the convenience of the description. Alternate boundaries can be defined so long as the specified functions and relationships thereof are appropriately performed.
This section will give a brief overview of the various functionality of a logistical management system with reference to
The logistical management system 100 may also include a plurality of user devices 1041, 1042, . . . and 104N (collectively and generically referred to as “user device 104”). According to embodiments, the user devices may comprise mobile electronic devices (e.g., cell phones, tablet computers, laptop computers), personal computers, or the like and may also be configured to connect to the communication network 110.
The logistical management system 100 may also include a control system 106 connected to communication network 110. The control system may comprise one or more computer systems (e.g., a computer system such as the one described with reference to
In some embodiments, the data store element 108 may contain segment information to be used to generate itineraries or routes between a first location and a second location. For instance, data store 108 may contain flight data segments for a plurality of air transportation providers, train schedules, shipping schedules, and the like.
The communication network 110 may comprise any suitable communication network. For instance, according to some embodiments, the communication network may comprise an Internet, WiFi, LAN, WLAN, WAN, PAN, etc.
Using the various components of the logistical management system 100, logistics for the physical transport of various items can be arranged.
As shown in the sequence diagram 200, a customer device 102 may send a request 202 to the control system 106 via communication network 110. The request 202 may include information relating to a particular item or package that needs to be transported as well as a GPS location of the current location of the package. Optionally, the control system 106 may return to the customer device 102 a quote 204 relating to a feasibility, timeline, or cost of transporting the item or package from the request. If the quote 204 is acceptable to user device 102, then it can transmit a confirmation 206 to control system 106 via communication network 110. Alternatively, communications 204 and 206 may be omitted in some embodiments and sequence can proceed directly to message 208 upon receipt of request 202.
After receiving the confirmation 206, the control system 106 may send a request message 208 to a number of user devices 104. The request message 208 may contain information relating to the specifics of the package to be transported as well as a location of the package and a destination. When a user device 104 determines to accept the request, it sends a confirmation message 210 to the control system 106. At this point, the sequence may optionally end. However, some embodiments of the sequence 200 allow for real-time changes to the transportation request 202.
When such a change is desired, a customer device 102 can transmit a change request message 212 to control system 106. The control system 106 may then generate and transmit a change request message 214 formatted for the user device 104. Upon receipt of the change request message 214, the user device 104 may send a confirmation message 216 to control system 106 and the control system 106 may then transmit a confirmation message 218 to the customer device 102.
One important aspect of transporting items or packages from one location to another is creating an itinerary or route for a user to take from the first location to the destination.
Each of the trip segments may be performed by different means of transportation. For instance, some may comprise ground transport and some may comprise air transport. Consider, for example, two trips between location A 302 and location C 306 that could be represented by routing diagram 300. The first trip may comprise segments 310 and 312. In this example a driver with, e.g., a user device 104 could start a location A 302 and proceed to location B 302 to pick up a package based on a received request 208. From location B 302 to location C 306, the package could proceed along segment 312, another ground route.
However,
A challenging aspect to transporting a package between two locations is determining an optimal path for that package. For instance, a package weighing 5,000 lbs. may have many fewer options than a package weighing 5 lbs. In the case of the 5,000 lb. package, freight transportation must be arranged, heavier trucks used, and lifts must be arranged at the pickup and destination. On the other hand, the 5 lb. package can easily fit in a common deliver van and placed on virtually any commercial flight or other means of transportation. Accordingly, an important aspect to determining the routing for a package involves considering the characteristics of a package. For instance, if a package requires heavy trucks, it could be that segment 312 is unavailable because that segment is a residential street that prohibits heavy trucks. Accordingly, in that case, to get to the heavy package to location C 306, routing might have to occur via segments 314 and 316, which may allow the passage of heavy trucks.
Thus, an important first step in routing a package from a first location to a second location will be to consider the various physical characteristics of the package. Consider a sample order that is to be flown from a pickup location to a destination. In this case, as part of the request 202, the control system 106 may receive a total volume of the package and an associated weight of that package from the customer device 102. The control system 106 can then determine the correct vehicles and/or trip segments that are available for transportation of the package.
After determining, for instance, the correct vehicle types for transporting the package, the control system 106 can calculate an optimum path for those vehicles. This can begin by verifying the addresses contained in the request message 202 for the pickup and destination locations and geocoding them according to some embodiments. If the package is to travel via air, the control system can also determine the closest airports and query a database (e.g., data store 108) of flight segments connecting the two airports. The search may be constrained by, for instance the correct vehicle type that was determined previously. For instance if the package is big and/or heavy, the query may be constrained to return only freight lights. If the package is small and/or light, on the other hand, the search might not be so constrained.
The control system 106 may calculate a drive distance between the pickup location and the pickup airport and the destination airport and the ultimate destination. After calculating the drive distance, the control system 106 may further exclude flights that will be temporally unavailable because of the required drive times. Additionally, the control system 106 may consider factors such as congestion at an airport and traffic when making this determination.
At step 504, the control system 106 can query a data store 108 to retrieve a number of itineraries each comprising, for instance, a number of trip segments. The control system 106 can eliminate impossible or impractical itineraries and generate a set of possible itineraries at step 506. This set of possible itineraries can be validated against a set of pre-determined rules at step 508 to determine a subset of valid itineraries. From the subset, an itinerary can be selected at step 510. According to some embodiments, the itinerary may be selected by sorting the subset according to various criteria (e.g., cost, speed, etc.) and choosing the highest ranked itinerary. Alternatively, the subset could be presented to a customer and the customer allowed to select the itinerary.
As shown in
After the incompatible segments are eliminated at step 604, the control system 106 may construct a set of possible itineraries or routes using the compatible segments at step 606.
After transportation for a package has been routed, a user 104 needs to be dispatched to pick up the package. In some embodiments, the control system 106 can offer the route to the closest driver 104 and, if they do not respond in time, offer the job to the next driver. This can greatly reduce the time to dispatch a driver. Alternatively, the control system 106 can offer the route by sending a request 208 to a plurality of user devices 104 at the same time and give the job to the first user device 104 that sends a confirmation message 210 to the control device 106.
When a user/driver accepts a route via a mobile device 104, the control system 106 can automatically send route information to the mobile device 104 to the pickup location. When the driver arrives at the pickup location, a package label is scanned and a client signature may be captured. The scan information and the captured signature may then be uploaded to the control system 106. At this point the control system 106 may verify that the scan information is valid. Additionally, each time the package label is scanned, the scan information may be geotagged.
In order to confirm that the package is correct, the control system 106 must verify the scan information against order information stored by the control system 106 and/or a unique global identifier associated with the package. If there is a problem with the scan information, then the control system 106 may prompt the driver 104 to replace the package label with a new one and the package can be associated with a new identifier at the control system 106.
Upon arrival at the destination, the driver can again scan the package label and the scan information can be geotagged and sent to control system 106 where it can be verified. If the destination is the starting point of a subsequent trip segment the control system 106 can provide additional information to the user device 104. For instance certain air carriers require an airway bill to accept a package for transport. These airway bills contain information relating to the package (e.g., names of the sender and recipient, destination address, etc.). Frequently each carrier requires the airway bill in a different format with slightly different information. Accordingly, based on the carrier, the control system 106 can generate a representation of the appropriate airway bill and send that data to the user device 104.
An example of the generated airway bill is shown in
At step 706, the control system 106 may transmit route information to the selected user device 104. The route information may include information detailing a route that the user should take from a first location to a second location. When the user 104 reaches the pickup location and scans the package information, the package information can be transmitted to and received by the control system 106. The package scan information can then be processed to verify that the scan information is valid against saved information associated with the package such as a unique global identification number, at step 710. At step 712 the control system 106 can receive second scan information from the selected user device 104 when it reaches its destination location.
When the user device 104 reaches the pickup location, package label information can be scanned. The scanned package information can then be transmitted to the control system 106 at step 808. The scanned package information may also include an image of a signature from the sender. When the user device 104 reaches its destination, the package label can be scanned a second time and the second scan information can be transmitted to control system 106. In response to receiving the transmitted second scan information, the control system can send transit document information to user device 104. The transit document information may comprise a graphical representation 406 of a transit document associated with a carrier according to some embodiments.
The following example describes a possible use case according to embodiments of the disclosure. For convenience, this example will be described with reference to
Consider a situation where a user, Client A, wants to ship two packages containing ocular tissue from an eye bank to a hospital. Because the ocular tissue can expire in a matter of just a few hours, Client A is unable to ship with any next day provider. Instead, Client A needs the shipments to be completed on time and as fast as possible because the recipient is likely scheduled for a major surgery upon arrival of the shipment.
To initiate a shipment, Client A enters relevant origin information (e.g., pickup address, pickup time, etc.) into device 102. The device may then display information validating the origin information entered into device 102 by Client A. According to some embodiments, this validation information can take the form of a graphical map representation of the pickup information. Client A may also enter a second address (e.g., a destination address) into device 102. This second address may be validated in a similar fashion to the origin information entered by client A into device 102.
The device 102, according to some embodiments, may also be configured to prompt Client A to enter relevant characteristic information about the package or packages to be delivered (e.g., he dimensions, weights, etc.) In this example, let us assume that one of the two packages to be shipped happens to be light and oddly shaped while the other is quite heavy due to the required refrigeration. Device 102 may be configured to then prompt Client A to enter relevant billing and/or reference number and finally the recipient surgeon's email address for notification of the status of the shipment.
After any relevant information is entered into device 102, a request 202 is generated and sent to a remote server 106 via an appropriate network 110. The server 106 may then determine the closest airports to the origin address and destination address and then searches a database (e.g., memory store 108) containing available flights. Based on the available flights, the server 106 may determine the possible routes. However, the soonest flight is not always valid. A driver needs time to pickup the package and drive to the airport. Airlines have different cut off times and airports have different levels of congestion. Server 106 may maintain a database of every airport, airline cut off times, average time to tender a package to the airline as well as cargo hours. This ensures that the final route takes in all possible temporal variables associated with tendering a package. For instance, in this example, assume that Client A anticipates a route from San Diego Airport to JFK. However, the San Diego cargo areas open later so, although the flight leaves sooner, server 106 may be configured to choose the longer drive to LAX because the cargo at LAX does not close. It also chooses Airline #1 instead of Airline #2 based on a cut off time for delivery for Airline #1 is only 60 minutes instead of 90. This gives the driver time to get to LAX in time to tender the package to get it on the optimal flight. The sever 106 may also be configured to add the drive time, airline cut off time, airport delay time and drive to destination time to the airline departure to calculate the fastest possible route that is achievable for that shipment.
An additional factor that server 106 may be configured to consider when determining the appropriate route is the certifications of the available drivers. For instance, in this example, it is possible that not every driver is certified to carry human tissue. Accordingly, the server 106 can be configured to only select drivers that have the appropriate certifications to carry that commodity type. For instance, only drivers that have dangerous goods training are dispatched for dangerous goods shipments. In some embodiments, each driver's profile when he or she logs in with device 104 is linked a corresponding driver profile maintained by the server 106. According to some embodiments, the driver profile maintained by server may contain additional data including certifications, vehicle information, vehicle capacity, driver history, etc.
In this example, the delivery requires a driver that is certified to carry human tissue. If there happen to be four drivers in the area near the pickup location, the server 106 can chose among them. If, of the four drivers in the area, three have the certifications needed to carry human tissue, then the server 106 can be configured to choose among them based on additional criteria. For instance, if only two of the certified drivers have a van large enough to accommodate the shipment, then the server 106 can be configured to choose one of those drivers either randomly or according to some other criteria (e.g., seniority, performance, etc.). According to some embodiments, the server 106 may sends a push notification (e.g., request 208) to the closest driver's device 104 via network 110. If that first driver is unable to take the shipment at this time do he can reject the order by providing an appropriate input to device 104. The rejection is then transmitted to the server 106 via network 110. Server 106 may then be configured to automatically sends a push request (e.g., request 208) to the next closest driver's device 104 that meets the criteria. When the second driver accepts (e.g., confirmation 210) she can automatically be routed to the pickup location by device 104.
While the driver is en route to the pickup location, server 106 may provide client device 102 information confirming that the driver is en route. In some embodiments, client device 102 may be configured to display information indicating a specific location along the route (e.g., segment 310) at which the driver is currently located.
In some embodiments, the client device 102 may be configured to receive labels for each package to be printed (by, e.g., Client A) and placed on each of the packages to be shipped. When the driver arrives to receive the packages, she can use device 104 to scan the label on each piece of the order to ensure that every piece and only the pieces associated with that order are collected. If it device 104 determines that there is an error associated with one of the labels (e.g., Client A put a wrong label on a piece), then device 104 can be configured to associate a new label with the order. Additionally, if no label is present on a package, device 104 can be configured to associate a new or blank label with the order and to communicate that information to server 106
After scanning each piece with device 104, the driver may be prompted to collect a signature on, for instance, a graphical user interface associated with device 104. Client A inputs a signature into device 104 and can also be prompted to enter additional information (e.g., a name, company, department, etc.) In some embodiments this information is transmitted to server 106 where it can be subsequently transmitted to client device 102 for viewing or, additionally and/or alternatively, for viewing on a client web interface.
Once the driver has successfully received the packages, device 104 can be configured to automatically route the driver to the destination, which in this example is LAX. When the driver arrives at LAX, the driver input a confirmation to that effect into device 104 and be, again, prompted to scan each package. After scanning, the scan information is transmitted to server 106 and, in some embodiments, an indication of the driver's successful arrival can be transmitted to a client device 102. In some embodiments, each scan may also be geotagged on a map, which can be viewed by clients using device 102.
Depositing the packages with the airline may require an air way bill (AWB). In some embodiments, the server 106 may be configured to transmit an electronic version (e.g., 404) of an AWB to the driver's device 104 with relevant fields filled in. The driver may then use the electronic version of the AWB 404 to fill out a paper AWB for the airline by simply copying the information from the received electronic version. The driver can then be prompted by device 104 to photograph the completed paper AWB and the photograph can be transmitted to server 106, where it can be associated with the order. Alternatively, in some embodiments, the electronic AWB can be transmitted directly to the airline by either sever 106 or by the driver's device 104.
If, in this example, a problem were to arise such that the chosen flight could not depart that day, then server 106 can be configured to make adjustments. In some embodiments, information indicating problems (e.g., an “unable do deliver” message) can be input to device 104 and transmitted to sever 106. The sever 106 can be configured to determine an alternative flight for the package and this change can be transmitted to the driver's device and, if necessary, a new electronic AWB 404 generated. Upon successful delivery of the packages, the driver can input information to device 102 indicating that the packages have been successfully delivered to the airline and this information can be subsequently transmitted to server 106. The driver can then receive an indication on device 104 releasing the driver from the order and indicating availability to be selected for additional orders.
In some embodiments, the sever system 106 may monitor the information from the airline to “listen” for the takeoff of the flight on which the packages are scheduled. In some embodiments, when the plane takes off, the server 106 may receive information notifying it of the takeoff and may update a workflow. Additional background tasks may also be initiated at this point to “listen” for the arrival of the plane at its destination. When the plan arrives, the server 106 system may receive information to that effect and may, subsequently, being the process (e.g., process 700) of selecting qualified drivers near the destination airport. And the process for transporting the packages from the destination airport to the final destination can be repeated essentially as discussed above.
Various embodiments can be implemented, for example, using one or more well-known computer systems, such as computer system 1000 shown in
