1. Technical Field
Embodiments of the subject matter disclosed herein relate to a transport management system for an asset in a distribution center or other area.
2. Discussion of Art
Distribution center activity may include transports of assets from one location to another location. Based on the volume of transports and limited amount of equipment (e.g., controlled or operated by workers) to transport the assets within the distribution center, order fulfillment time may not be as fast as desired. A work order may be assigned for each transport based on worker/equipment availability to collect such work order from a centralized location in the distribution center.
It may be desirable to have a system and method for managing transport systems that differ from those that are currently available.
In one embodiment, a method is provided. The method includes at least the following steps: identifying two or more transports from a work order, wherein the transports comprise respective movements of assets from respective first locations to respective second locations; prioritizing the two or more transports based on a geographic proximity between the movements of the two or more transports; and communicating information of the two or more transports as prioritized to equipment to complete the movements.
In an embodiment, a system is provided that includes a transport manager configured to store a work order and to identify two or more transports from the work order, wherein the transports comprise respective movements of assets from respective first locations to respective second locations; wherein the transport manager is configured to prioritize the two or more transports based on a geographic proximity between the movements of the two or more transports, and to communicate information of the two or more transports as prioritized to equipment to complete the movements.
In an embodiment, a system is provided that includes at least the following: a work order that defines two or more transports, wherein the transports comprise respective movements of assets from respective first locations in a distribution center to respective second locations in the distribution center; and a transport manager configured to receive a geographic location of at least one of a worker or equipment from a device, and to create a transport itinerary that combines at least two of the two or more transports based on an amount of distance traveled for each asset of each transport from the geographic location of the worker or the equipment; wherein the transport manager is further configured to communicate the transport itinerary to the device.
In an embodiment, a system is provided that includes at least the following: means for defining two or more transports, wherein the transports comprise respective movements of assets from respective first locations in a distribution center to respective second locations in the distribution center; means for receiving a geographic location of at least one of a worker or equipment from a device, and to create a transport itinerary that combines at least two of the two or more transports based on an amount of distance traveled for each asset of each transport from the geographic location of the worker or the equipment; and means for communicating the transport itinerary to the device.
Reference is made to the accompanying drawings in which particular embodiments and further benefits of the invention are illustrated as described in more detail in the description below, in which:
Embodiments of the invention relate to methods and systems for transport management. Such systems may reduce travel time and/or travel distance for the movement of assets within a distribution center. In particular, equipment and/or an worker can receive real time transport itineraries that assign transport(s) based on a set of factors. Suitable factors may include proximity of the worker or the equipment and a start location of the transport; types of equipment, health of equipment, remaining time left on an worker's shift, type of asset to be moved, type of vehicle the asset will be loaded onto, and other prioritization factors. A geographic location of the equipment and/or the worker can be utilized to assign transports in order to reduce a distance traveled for a transport or reduce a travel time for a transport. The transports and/or the transport itinerary can be communicated for dynamic management of asset transport and movement within a distribution center or other area.
The term “client asset” as used herein means a fixed asset or a mobile asset that is owned and/or operated by a client entity such as, for example, a railroad, a power generation company, a shipping company (e.g., land, sea, air, and/or a combination thereof), a mining equipment company, an airline, or another asset-owning and/or asset-operating entity. The terms “container” and “trailer” may be used interchangeably herein and refer to a storage medium configured to hold products, goods, or other shippable materials.
The term “vehicle” as used herein can be defined as an asset that is a mobile machine that transports at least one of a person, people, or a cargo. For instance, a vehicle can be, but is not limited to being, a truck, a rail car, an intermodal container, a locomotive, a marine vessel, a mining equipment, a stationary power generation equipment, an industrial equipment, a construction equipment, and the like. The term “hostler” as used herein can be defined as a person or machine that operates a vehicle to perform the transport of a container or trailer from a first location to a second location. The terms “terminal”, “yard”, or “distribution center” may be used interchangeably herein and refer to a location and/or facility where products, goods, or other shippable materials are shipped into and subsequently shipped out of by drivers of shipping vehicles.
“Software” or “computer program” as used herein includes, but is not limited to, one or more computer readable and/or executable instructions that cause a computer or other electronic device to perform functions, actions, and/or behave in a desired manner. For example, a component can be a portion of hardware, a portion of software, and/or a combination thereof. The instructions may be embodied in various forms such as routines, algorithms, modules or programs including separate applications or code from dynamically linked libraries. Software may also be implemented in various forms such as a stand-alone program, a function call, a servlet, an applet, an application, instructions stored in a memory, part of an operating system or other type of executable instructions. The form of software may depend on, for example, requirements of a desired application, the environment it runs on, and/or the desires of a designer/programmer or the like. “Computer” or “processing element” or “computer device” as used herein includes a programmed or programmable electronic device that can store, retrieve, and process data. “Non-transitory computer-readable media” include, but are not limited to, a CD-ROM, a removable flash memory card, a hard disk drive, a magnetic tape, and a floppy disk. “Computer memory”, as used herein, refers to a storage device configured to store digital data or information which can be retrieved by a computer or processing element. “Controller”, as used herein, refers to the logic circuitry and/or processing elements and associated software or program involved in controlling an energy storage system. The terms “signal”, “data”, and “information” may be used interchangeably herein and may refer to digital or analog forms.
The work order can be an instruction (e.g., written, digital, verbal, among others) in which an asset in the distribution center is to be transported from a first location to a second location. Moreover, the work order can include one or more transports in which a transport is a movement from a first location to a second location within the distribution center. (That is, the transports are respective movements of assets from respective first locations to respective second locations, e.g., the assets may be moved from the same first location to the same second location, or moved between different first and second locations.) Additionally, the work order can include a pickup, a drop off, and/or a suitable combination thereof. Moreover, the transport that includes a movement from a first location to a second location can be a pickup of an asset, a drop off of an asset, and/or a suitable combination thereof. For instance, a movement from a first location to a second location can be a pickup (e.g., pickup at first location and drop off at second location), a drop off (e.g., drop off of an asset at second location from first location being present location) of an asset, or a combination of a pickup and drop off (e.g., drop off at first location and pickup at second location) of an asset. The work order can also include a suitable number of movements (e.g., pickups, drop offs, or a combination thereof).
In one embodiment, hostlers are shown what containers need to be extracted from the yard (e.g., distribution center) for dispatch (e.g., transport from a first location to a second location). The hostlers self-prioritize by working in teams and “own” rows or sections of the yard such that owning a row or section indicates responsibility for transport therein. Using an algorithm, tools, and/or screens, an embodiment may affect the efficiency of assigning transfer of assets. Some embodiments of the invention can bring containers from the distribution center to an outbound vehicle, location, train, on-road driver, among others. The transport manager can assign a sequence of work orders (that include transports of assets) through a device (e.g., handheld, in-dash console, among others) to decrease the travel time for each transport and/or decrease a distance traveled for the asset being transferred (e.g., thereby improving the retrieval and/or load up process). The transport manager further allows for re-sequencing (e.g., adjusting a prioritization, re-prioritizing, among others) in the case of a trigger event. Such triggers can include a task taking longer than an expected time, a change in customer prioritization, new hostler resources (e.g., equipment, tools, among others) being added/subtracted from availability, new work orders being added to the queue, an area specific event (discussed in more detail below), an amount of traffic, among others. Additionally, events may include one or more of rail network effects, weather, incoming container/trailer information, pricing events, value of assets, among others.
The distribution center can be a shipping terminal, a railroad intermodal terminal, a yard, a loading/unloading dock, or a location and/or facility where products, goods, or other shippable materials are shipped into and subsequently shipped out of by drivers of shipping vehicles. The containers or trailers containing the products, goods, or materials are processed in and out of the distribution center. Furthermore, the equipment can be a suitable mobile asset or vehicle that transfers assets from one location to another, wherein the equipment can include a load capacity. By way of example and not limitation, the transfer of an asset for a transport (e.g., a movement from a first location to a second location) can be handled or completed by a worker (e.g., employee, human, user, two or more workers, among others) or by a equipment (e.g., vehicle, mobile machine, crane, machine, forklift, employee controlling the equipment, machine-controlled equipment, among others).
As an option, the system may include a wireless communication (COMM) device (not shown) operably interfacing to the transport manager 120 and configured to communicate with other devices (e.g., via radio frequency communication, cellular, Radio Frequency (RF), among others) operating within the distribution center. Such other devices may be hand-held devices, in-console devices, devices used by inspectors, devices located in cranes or devices located on-site transportation vehicles within the distribution center, and are configured to communicate with the transport manager. By way of example and not limitation, the transport manager can communicate the transport itinerary via the wireless communication. As discussed, the transport itinerary can include instructions to complete two or more transports. Additionally, the transport itinerary can include directions associated with the assigned two or more transports.
The transport itinerary can be communicated to a device 140 in via suitable medium. Suitable mediums can include wired, air, wireless, and/or a combination thereof. By way of example and not limitation, the device can receive the transport itinerary with two or more prioritized transports for assignment, wherein the assignment can be indicated by a receipt by a particular device (e.g., a device for a worker, a device for equipment, among others). In another example, the assignment of the transport itinerary can be designated by at least one of a name of a worker or a identification of equipment. A suitable device can be a scanner, a barcode reader, a wireless device, a touchscreen, a camera, a smartphone, a laptop, a computer, a portable computing device, portable scanner, a mobile device, a portable digital assistant (PDA), a tablet, a web camera, a device incorporated into equipment, a device incorporated into a two-way communication device, hand-held device, in-console devices, devices used by inspectors, devices located in cranes or devices located on-site transportation vehicles within the distribution center, among others.
The transport manager can further include an evaluation component 210 that analyzes the one or more work orders. For instance, the evaluation component can identify information from the work order, such as an asset, an asset destination (e.g., a location to drop off an asset, among others), an asset location (e.g., a location to pickup an asset, among others), a definition of the asset (e.g., contents, cost, vendor, manufacturer, customer, among others), an asset size, and an asset weight, among others.
The transport manager further can include a distribution center data collector 220 that can aggregate data associated with at least one of the distribution center, the equipment, and/or at least one worker. For instance, the distribution center data collector can aggregate geographic location data (e.g., worker geographic location, equipment geographic location, locations for pickups, locations for drop offs, destinations for movements of a transport, among others), distribution information (e.g., distribution center layout, landmark locations, routes, directions between locations, names of locations, identifications of landmarks, among others), worker information (e.g., worker schedule, worker name, worker identification, worker experience with equipment, worker real time geographic location, among others), equipment information (e.g., equipment type, equipment load capacity, equipment status, among others), and the like. In an embodiment, a real time geographic location can be defined as a geographic location of an entity (e.g., person, item, equipment, vehicle, etc.) based on an electronic device that communicates such geographic data, wherein the delay of electronic signals is taken into account to determine a real time location based on the device.
The transport manager can further include a match component 230 that prioritizes two or more transports to package into the transport itinerary. For instance, the match component can combine two or transports into the transport itinerary for assignment to equipment or a worker for transfer (e.g., completion of the movement(s) of each transport). The combination can be such that the transports from the work orders are prioritized rather than handled in a sequential manner. For example, the match component can prioritize transports based upon a distance traveled for each movement such that a transfer will use the least amount of distance traveled. In another example, the match component can prioritize transports based upon a time for travel for each movement that a transfer of an asset uses. In still another example, the match component can prioritize transports of assets based upon the distance of the included movement(s) and a geographic location of a worker or equipment. The match component identifies efficient match making for two or more transports and at least one of a worker or equipment based on reducing distance traveled for the asset, reducing time traveled for the asset, among others. The match component can further utilize suitable factors to prioritize transports, wherein the factors can be, for instance, proximity of the worker or the equipment and a start location of the transport; types of equipment, health of equipment, remaining time left on an worker's shift, type of asset to be moved, type of vehicle the asset will be loaded onto, and other prioritization factors.
In another example, the match component can prioritize the two or more transports based on factors, such as traffic, an area specific event, an event trigger, and the like. For example, the match component can receive data related to an area specific event and include such condition in the prioritization and, in turn, assignment of transfer of an asset. An area specific event is an event occurring in an area or otherwise directly affecting operations in the area. For instance, the area specific event can be inoperable equipment, an unavailable worker, a construction of an area, a repair to an area, a power outage for the area, a repair to equipment, an emergency event in the area, a hazardous condition, and the like. In another example, the system can dynamically adjust prioritization of two or more transports based on traffic within the distribution center. Thus, if the assignment of transports is such that the location of workers and/or equipment is within a proximate geographic area of the distribution center, the match component can re-adjust accordingly in order to update upcoming work orders as well as, or in the alternative, re-assign work orders to alleviate the traffic.
In one embodiment, the transport manager stores information related to the system in a data store 240. The data store can include relationship information such as work order, distribution center information, worker information, transport information, asset data, transfer status, completed work orders, assignment data, prioritization data, time/date information, duration of transport, distance of transport, geographic locations, equipment information, equipment associated with the distribution center, and/or a suitable combination thereof.
The data store can be, for example, either volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory. The data store of the subject systems and methods is intended to comprise these and/or other types of memory. The data store can be a server, a database, a hard drive, a solid state drive, a pen drive, an external hard drive, a portable hard drive, a cloud-based storage, and the like.
The flow chart 350 illustrates a transport prioritization technique as provided by the systems 100, 200, 400, and 800 utilizing at least the transport manager 120. The order source 320 can broadcast and/or communicate the work orders to the worker(s) based upon prioritization provided by the transport manager (not shown). At reference numeral 311, the worker enters the entrance/exit 310 and receives two or more transports that are assigned for transfer based on at least the movements of such transports as the worker is traveling. Once the transport itinerary depicting the transports is received, the worker travels to drop off the asset or pickup an asset (e.g., DROP/PICKUP 330) at reference numeral 311. At reference numeral 312, the worker travels to pick up an asset or drop off the asset (e.g., PICKUP/DROP 340). At reference numeral 313, the worker travels to the entrance/exit 310 completing the transport itinerary. Thus, the distance traveled for the asset(s) and/or the travel time for the asset(s) is reduced in flow 350 versus the flow in 300.
By way of example and not limitation, the model component can employ the following techniques. The model component can utilize data from, for instance, a client, customer, a distribution center, among others (See
Turning briefly to
The model component can provide a solution such as damped least squares (e.g., regularization). The model component indicates values can be distributed around an average, and may affect or improve conditioning of A and ATA. This can solve the normal equations using conjugate gradient method: ATAx=ATb. However, if values are outside of expected range, one embodiment of the system may increase the damping on those variables and re-solve. A complete travel matrix can be utilized. In another embodiment, an amount of trips can be regulated, and waypoints or locations can be restructured to increase system performance.
The aforementioned systems, components, (e.g., transport manager, transport itinerary, work orders, among others), and the like have been described with respect to interaction between several components and/or elements. Such devices and elements can include those elements or sub-elements specified therein, some of the specified elements or sub-elements, and/or additional elements. Further yet, one or more elements and/or sub-elements may be combined into a single component to provide aggregate functionality. The elements may also interact with one or more other elements not specifically described herein.

The method further includes assigning a transfer of the prioritized two or more transports to equipment or an worker based on a location of each, wherein the distribution is based on a lowest total distance traveled. The method further includes identifying a real time geographic location for at least one of the equipment or the worker. The method further includes communicating an additional transport to the equipment or the worker while the equipment or the worker location is between the first location and the second location. The method further includes clearing the work order based on completion of the movement for the two or more transports. The method further includes prioritizing the two or more transports based on at least one of an amount of traffic in a location or a load capacity of the equipment. The method further includes prioritizing the two or more transports based on an area specific event. The area specific event can be at least one of an inoperable equipment, an unavailable worker, a construction of an area, a repair to an area, a power outage for the area, a repair to equipment, an emergency event in the area, or a hazardous condition. The method further includes prioritizing one or more of the transports into a hold itinerary based on the movement of the transport being proximate to the area specific event.
In one embodiment, the prioritizing is based on geographic proximity.
In an embodiment, a device, component, a portion of hardware, a portion of software, a processor, or a combination thereof, can provide at least the following steps: identifying two or more transports from a work order, wherein the transports comprise respective movements of assets from respective first locations to respective second locations; prioritizing the two or more transports based on a geographic proximity between the movements of the two or more transports; and communicating information of the two or more transports as prioritized to equipment to complete the movements.
