Description

[Technical Field]

[0001] The present disclosure relates to a destination suggestion device, a destination suggestion system, and a destination suggestion method. [Background technology]

[0002] Patent Document 1 discloses a parking lot management system in which a management terminal that manages the usage status of a parking lot and an image processing terminal that analyzes and processes image data captured by a surveillance camera located in a position where it can capture images of vehicles entering and exiting the parking lot and vehicles parked in the parking lot's spaces are connected to each other so that they can communicate with each other via a public communication line network.In the parking lot management system, the image processing terminal sets a virtual measurement line and measurement area at the vehicle entrance and exit of the parking lot based on image data of the parking lot captured by the surveillance camera, and when it detects that a vehicle has passed through this virtual measurement line and measurement area, it detects the vehicle's entry and exit to the parking lot and sends this to the management terminal.When the management terminal receives the vehicle's entry and exit to the parking lot sent from the image processing terminal, it calculates the usage status of the parking lot and displays the usage status on a display device located near the vehicle entrance and exit of the parking lot.

[0003] Patent Document 2 discloses a parking guidance system that guides vehicles in a parking lot for a commercial facility that has multiple usage areas. The parking guidance system includes a vehicle identification information acquisition unit that acquires vehicle identification information for identifying entering vehicles that have entered the parking lot, a visit frequency storage unit that stores the visit frequency of entering vehicles associated with the vehicle identification information, a recommended parking position determination unit that determines a parking space or group of parking spaces that should be used by the entering vehicle based on the visit frequency, and a guidance information output unit that generates parking guidance information for guiding entering vehicles to a parking space or group of parking spaces and outputs the parking guidance information on a predetermined display device.

[0004] Patent Document 3 discloses a parking lot guidance system consisting of a parking space designation means and a monitoring means. The parking space designation means uses an entrance television camera to capture images of vehicles entering the parking lot, processes the video signal from the entrance television camera to determine the size of the entering vehicle, detects and stores vacant parking spaces in the parking lot, and displays the information based on the signal that identifies the parking space. The monitoring means also uses multiple on-site television cameras to capture images of the parking lot, processes the video signals, identifies vehicles corresponding to data read from an entering vehicle data memory, and compares the data with a map of the parking lot to determine the vehicle's location.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2023-146976 [Patent Document 2] Japanese Patent Application Laid-Open No. 2017-157036 [Patent Document 3] Japanese Patent Application Publication No. 9-91591 Summary of the Invention [Problem to be solved by the invention]

[0006] In recent years, there has been a demand for more efficient unloading and loading operations at large offices (hereinafter sometimes referred to as "yards") of transportation companies and other businesses, where tractors (so-called transport trucks) pulling trailers (an example of a vehicle) loaded with many loads are concentrated. Furthermore, because the cargo transported by trailers is packed with a wide variety of items (e.g., food, refrigerated or frozen foods, electronic components, etc.), there is a challenge in that the priority of unloading and loading operations varies for each type of cargo. Therefore, there has been a demand for technology that can improve the efficiency of unloading and loading operations at yards by managing trailer parking positions in accordance with the schedule for unloading and loading operations.

[0007] The above-mentioned Patent Documents 1 to 3 disclose technologies for guiding vehicles based on the parking lot usage status or the frequency of vehicle visits. However, when determining parking positions based solely on the convenience of the parking lot, the efficiency of unloading and loading cargo at the yard can be improved by reducing the efficiency of trailer movement between the parking lot and the work site where the cargo is unloaded and loaded, which can reduce the efficiency of unloading and loading cargo at the yard.

[0008] The present disclosure has been devised in consideration of the above-mentioned conventional circumstances, and aims to provide a destination suggestion device, a destination suggestion system, and a destination suggestion method that suggest trailer parking positions and make loading or unloading operations more efficient. [Means for solving the problem]

[0009] The present disclosure provides a destination suggestion device including: an acquisition unit that acquires an estimated arrival time of an object at a base including a plurality of parking spaces where the object will be parked and a plurality of task areas where a task corresponding to the object will be performed, information about the task corresponding to the object, and scheduled information about the task scheduled in each of the plurality of task areas; a first determination unit that determines the task area where the task corresponding to the object will be performed based on the estimated arrival time, the information about the task, and the scheduled information about the task; a second determination unit that determines one of the plurality of parking spaces as a stopping space where the object will be parked; and an output unit that outputs information about the stopping space.

[0010] The present disclosure also provides a destination suggestion system that includes an object management system that manages information regarding an object moving between multiple bases, a task management system that manages tasks corresponding to the object at a predetermined base among the multiple bases, and an area management system that manages, at the predetermined base, multiple task areas where the tasks are performed and multiple parking spaces where the object is parked, wherein the object management system transmits to the area management system an estimated arrival time at which the object moving to the predetermined base will arrive at the predetermined base and information about the task corresponding to the object, and the task management system transmits to the area management system schedule information for tasks scheduled at the predetermined base in each of the multiple task areas where the tasks are performed, and the area management system determines, based on the estimated arrival time, the task information, and the task schedule information, a task area where the task corresponding to the object that has not yet arrived at the predetermined base will be performed, determines one of the multiple parking spaces as a parking space where the object will be parked, and outputs information about the parking space.

[0011] The present disclosure also provides a method for suggesting a destination, performed by at least one processor, which acquires an estimated arrival time for an object to arrive at a base including a plurality of parking spaces where the object will be parked and a plurality of task areas where tasks corresponding to the object will be executed, information about the task corresponding to the object, and scheduled information about the tasks scheduled in each of the plurality of task areas, determines the task area where the task corresponding to the object will be executed based on the estimated arrival time, the information about the task, and the scheduled information about the task, determines one of the plurality of parking spaces as a stopping space where the object will be parked, and outputs information about the stopping space.

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, with reference to the drawings as appropriate, detailed embodiments of a destination suggestion device, a destination suggestion system, and a destination suggestion method according to the present disclosure that suggest trailer parking positions and improve the efficiency of loading and unloading operations will be described in detail. However, more detailed explanations than necessary may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following explanation and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following explanation are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter recited in the claims.

[0015] First, terms used in the following embodiments will be defined. (1) Trailer: A container-like object with a rectangular parallelepiped casing that can carry one or more cargo items and is towed by a tractor. (2) Tractor: A vehicle part of a transport truck that can dock (connect) with a trailer or detach the trailer. (3) Yard: A large office or site of a transport company or the like where tractors (so-called transport trucks) pulling trailers are gathered.

[0016] First, a yard YRD in which a yard management system MS1 of a logistics management system 100 (see FIG. 2) according to an embodiment is introduced will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of a yard YRD.

[0017] The yard YRD is a vast site owned by a business such as a transportation company. Specifically, the yard YRD includes within its site a gate GT for carrying out procedures for checking in (entering) and checking out (exiting) trailers TR into the yard YRD, at least one parking area PAR1, PAR2, PAR3, PAR4, PAR5 having a plurality of parking spaces, and a warehouse WH where trailers TR are loaded or unloaded. It goes without saying that the yard YRD shown in FIG. 1 is merely an example and is not limited to this.

[0018] The gate GT is passed by both trailers TR entering the yard YRD and trailers TR leaving the yard YRD. At least one camera CM1 is installed at the gate GT to capture images of trailers TR entering and leaving the yard YRD.

[0019] The camera CM1 is disposed at the gate GT and captures identification information, such as a license plate or trailer ID, that can identify a trailer TR entering or exiting the premises. The camera CM1 transmits the captured image to the character recognition unit 111 of the terminal device P1. Note that, although the present disclosure illustrates an example in which an image of a license plate or trailer ID is captured as identification information of a trailer TR, the method of acquiring the identification information is not limited to capturing an image using a camera. For example, the identification information may be acquired by a reader capable of reading information such as an IC card that stores the identification information of the trailer TR or a driver's license, or by visual inspection by an administrator at the gate GT who manages the entry and exit of trailers TR.

[0020] Each of the plurality of parking areas PAR1 to PAR5 has parking spaces for parking one or more trailers TR. Each of the plurality of parking spaces is assigned an identification number that allows each parking space to be identified.

[0021] The warehouse WH stores cargo unloaded from the trailer TR or cargo to be loaded onto the trailer TR. The warehouse WH includes at least one dock DCK1, DCK2, DCK3, DCK4, DCK5, DCK6, DCK7, and DCK8 having multiple dock ports for loading or unloading cargo from or to the trailer TR. Each of the multiple dock ports is assigned an identification number that allows identification of the dock port.

[0022] Next, the logistics management system 100 will be described with reference to Fig. 2. Fig. 2 is a block diagram showing an example of the overall configuration of the logistics management system 100 according to an embodiment and an example of the internal configuration of a yard management system MS1. Note that the logistics management system 100 shown in Fig. 2 shows an example including one yard management system MS1, one transportation and delivery management system MS2, and one warehouse management system MS3, but there may be multiple yard management systems MS1, multiple transportation and delivery management systems MS2, and multiple warehouse management systems MS3 managed by the logistics management system 100.

[0023] The logistics management system 100 includes at least one yard management system MS1 that manages the yard YRD, at least one transportation and delivery management system MS2 that manages the process of transporting and delivering cargo by trailer TR, and at least one warehouse management system MS3 that manages inventory in the warehouse WH.

[0024] The yard management system MS1 includes a terminal device P1, a camera CM1, and a monitor MN.

[0025] The terminal device P1 includes a communication unit (not shown), a processor 11, and a memory 12. The terminal device P1 may be realized by, for example, a personal computer (hereinafter referred to as "PC"), a notebook PC, a tablet terminal, or the like.

[0026] Although the communication unit is not shown in Figure 2, the processor 11 is connected to external devices of the terminal device P1 (for example, a transportation and delivery management system MS2, a warehouse management system MS3, a camera CM1, and a monitor MN, etc.) so that data communication is possible.

[0027] The terminal device P1, the transportation and delivery management system MS2, and the warehouse management system MS3 may be connected via one or more networks, which may be a wired network, a wireless network, or a combination of a wired network and a wireless network. The wired network may be, for example, at least one of a wired local area network (hereinafter referred to as "LAN"), a wired wide area network (hereinafter referred to as "WAN"), and a power line communication (PLC), or may be another network configuration capable of wired communication. On the other hand, the wireless network may be at least one of a wireless LAN such as Wi-Fi (registered trademark), a wireless WAN, and a mobile communication network such as 4G or 5G, or may be another network configuration capable of wireless communication.

[0028] The processor 11 is configured using, for example, a central processing unit (hereinafter referred to as "CPU"), a digital signal processor (hereinafter referred to as "DSP"), or a field programmable gate array (hereinafter referred to as "FPGA") etc. The processor 11 performs various processes and controls in cooperation with the memory 12. Specifically, the processor 11 references the programs and data stored in the memory 12 and executes the programs to realize various functions such as a character recognition unit 111, a trailer arrival time management unit 112, a dock schedule management unit 113, and a stop position schedule unit 114.

[0029] The character recognition unit 111 detects the license plate appearing in the captured image transmitted from the camera CM1, performs character recognition processing, and recognizes the license plate of the trailer TR. The character recognition unit 111 associates the information on the recognized license plate of the trailer TR with information on the time the captured image was taken, and outputs the information to the trailer arrival time management unit 112. Note that the arrival time information associated with the license plate information may be the time when the trailer TR completed the entry procedure at the gate GT.

[0030] The trailer arrival time management unit 112 acquires information about trailers TR scheduled to enter the yard YRD, which is transmitted from the transportation and delivery management system MS2. The information about the trailer TR here includes the identification information of the trailer TR (in this disclosure, license plate information), the starting point of the trailer TR (departure base or departure point, etc.), the type of cargo the trailer TR is transporting (e.g., ice cream, electronic parts, or food, etc.), the arrival time at the yard YRD, the work content for the cargo that is the purpose of entering the yard YRD (loading or unloading), etc. The trailer arrival time management unit 112 stores the information about the trailer TR in a trailer arrival time management table Dt11 and manages it for each trailer TR.

[0031] Here, the trailer arrival time management table Dt11 will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of the trailer arrival time management table Dt11. The information managed by the trailer arrival time management table Dt11 shown in Fig. 3 is an example and is not limited to this. Furthermore, the trailer ID shown in Fig. 3 may be transmitted in advance from the transportation and delivery management system MS2, or may be assigned by the terminal device P1 for identifying and managing trailers TR entering the yard YRD. In the present disclosure, an example in which the trailer ID is assigned by the terminal device P1 will be described.

[0032] When the trailer arrival time management unit 112 acquires information about trailers TR transmitted from the transportation and delivery management system MS2, it generates a trailer ID for each trailer TR to identify the trailer. The trailer arrival time management unit 112 stores the information about the trailer TR and the trailer ID for each trailer TR in the trailer arrival time management table Dt11. For example, the trailer arrival time management table Dt11 stores, as information about the trailer TR with the license plate "QK-456-37", the departure point "Costco Hampton", the type of cargo "groceries", the predicted arrival time of the trailer TR "12:00", and the purpose "Pick_up (loading)", in association with the trailer ID "101" of this trailer TR in the trailer arrival time management table Dt11.

[0033] The trailer arrival time management unit 112 refers to the entry and exit times of trailers TR recorded for each combination of trailer TR type and purpose collected in advance at this yard YRD. The entry and exit times of trailers TR for each combination of trailer TR type and purpose may be stored in memory 12 or the like. The trailer arrival time management unit 112 calculates the average of the entry and exit times of the trailers TR referenced, and calculates the work time required at the dock when the cargo type is "groceries" and the purpose is "Pick-up (loading)." In the example shown in FIG. 3, the work time required when the cargo type is "groceries" and the purpose is "Pick-up (loading)" is predicted to be "60 minutes."

[0034] Furthermore, the trailer arrival time management unit 112 stores the work time "60 minutes" in the trailer arrival time management table Dt11, and then predicts (calculates) the exit time at which this trailer TR will exit the yard YRD based on the cargo type "groceries" and the work time "60 minutes." In the example shown in FIG. 3, the exit time is predicted to be "11:30." The trailer arrival time management unit 112 stores the calculated exit time "11:30" in the trailer arrival time management table Dt11.

[0035] As described above, the arrival time acquired from the transportation and delivery management system MS2 is time information that predicts the arrival time of the trailer TR. Therefore, the trailer arrival time management unit 112 may acquire, via the Internet, environmental information such as traffic information and weather information on the travel route between the starting point and the position of the yard YRD, or information on the current location of the trailer TR from a Global Positioning System (GPS) mounted on the trailer TR or the truck towing the trailer TR, until the trailer TR arrives at the gate GT of the yard YRD. In such a case, the trailer arrival time management unit 112 may update the arrival time information stored in the trailer arrival time management table Dt11 by re-predicting the arrival time of the trailer TR based on the various acquired information.

[0036] Furthermore, when the trailer arrival time management unit 112 acquires the license plate information of the trailer TR acquired from the character recognition unit 111, it determines whether or not the trailer arrival time management table Dt11 stores information on the same license plate as the acquired license plate. If the trailer arrival time management unit 112 determines that information on the same license plate is stored, it updates and confirms the information on the arrival time of the trailer TR corresponding to the same license plate to the time the license plate was detected (i.e., the time the trailer TR entered the gate GT).

[0037] For example, in the example shown in Fig. 3, the trailer arrival time management unit 112 determines the arrival time corresponding to license plate "AB-123-44" to be "10:30" and the arrival time corresponding to license plate "YB-788-11" to be "10:00." Note that in Fig. 3, for ease of explanation, predicted arrival times that have not yet been confirmed are written in thin type, while confirmed arrival times are written in bold type.

[0038] If the trailer arrival time management unit 112 determines that information of the same license plate is not stored, it may generate a notification to the administrator that the trailer TR is not scheduled to enter the yard YRD, or may accept manual input of information about the trailer TR by the administrator. This allows the trailer arrival time management unit 112 to automatically determine the dock (dock port) usage schedule (described later), the parking position of the trailer TR, or the route to the parking position, even in the case of an unexpected entry of a trailer TR.

[0039] When the trailer arrival time management unit 112 obtains the arrival time (predicted) of the trailer TR from the transportation and delivery management system MS2, it outputs information about the trailer TR, including information about the predicted arrival time of the trailer TR, to each of the dock schedule management unit 113 and the stop position schedule unit 114.

[0040] The dock schedule management unit 113 manages the usage schedule of each of the multiple dock ports that docks DCK1 to DCK8 have. The dock schedule management unit 113 obtains availability information for the docks (i.e., each of the multiple dock ports that docks have) from the warehouse management system MS3 that manages the warehouse WH. The dock availability information here refers to identification information for each dock and information such as time periods when there are no plans to use each dock (i.e., no plans to load or unload cargo). In addition, the dock schedule management unit 113 obtains information about trailers TR that have arrived (entered) the yard YRD from the trailer arrival time management unit 112 (e.g., information such as arrival time, product type, working time, or departure time).

[0041] The dock schedule management unit 113 calculates weights f(a, g, d, t) for determining the dock (dock port) where cargo from the trailer TR is to be loaded or unloaded, based on the acquired information about the trailer TR and the available dock information. The weights f(a, g, d, t) are calculated, for example, based on the arrival time a of the trailer TR, the type of cargo g, the available dock information d, and the work time t.

[0042] Based on the calculated weights f(a, g, d, t), the dock schedule management unit 113 determines which dock (dock port) should be used by each trailer TR scheduled to enter the yard YRD in order to improve the overall profit of the yard YRD, i.e., the efficiency of loading or unloading cargo from the trailer TR. The dock schedule management unit 113 determines a dock usage schedule based on the weights f(a, g, d, t). The method for determining the dock will be described in detail with reference to FIGS. 4 and 5. Based on the determined schedule, the dock schedule management unit 113 generates a dock usage schedule table and outputs it to the stop position schedule unit 114 and the warehouse management system MS3.

[0043] The dock usage schedule determination method in the present disclosure is, as an example, a method in which a scheduling algorithm (Earliest Due Date, EDD) is applied to determine the priority of trailers TR for loading or unloading based on the delivery date (deadline) of cargo, and is useful when the delivery date of goods is tight. Therefore, the calculation example of the weight used to determine the dock usage schedule is just an example and is not limited to this. The weight f may be calculated using one or more arbitrary parameters based on the matters (scheduling algorithm) that the manager wants to prioritize.

[0044] Examples of scheduling algorithms include First-Come, First-Served (FCFS), which determines the priority of trailers based on the order in which they arrive and minimizes the waiting time of trailers in parking areas; Priority Scheduling, which assigns priorities based on the type of cargo on trailers and is useful when there are large differences in the importance or urgency of the goods; Shortest Processing Time (SPT), which minimizes the time trailers spend at the dock based on the shortest working time required to load or unload cargo and is useful when the length of working time varies greatly; Round Robin, which divides daytime operating hours into slots or rounds and loads or unloads one trailer in one round to fairly distribute work for trailers; and Multi-Level Feedback, which uses a multi-level feedback queue system to change the priority queue based on waiting time and flexibly load or unload cargo from trailers with different working times or different priorities. Queue (MLFQ), or if more complex cargo scenarios, schedule optimization, etc. are required, metaheuristic algorithms such as simulated annealing or genetic algorithms that explore the search space of dock usage schedules to find a solution (scheduling) may be used as desired.

[0045] The stop position schedule unit 114 acquires information about the trailers TR output from the trailer arrival time management unit 112 and the dock usage schedule table output from the dock schedule management unit 113. The stop position schedule unit 114 determines the stop positions of each trailer TR whose dock usage schedule has been completed, and information about the travel route from the gate GT to the stop position, in order of earliest arrival time (predicted) at the yard YRD. The method for determining the stop positions of the trailers TR will be described with reference to Figures 8 and 9.

[0046] The stopping position scheduler 114 stores information about the determined stopping position and travel route of the trailer TR in the trailer stopping position management data Dt12. The stopping position scheduler 114 also outputs a guidance screen SC (see FIG. 10) including information about the determined stopping position and travel route of the trailer TR to a monitor MN viewed by the manager. The guidance screen SC may be loaded on a tractor and transmitted to a car navigation system that can be viewed by the driver.

[0047] The trailer parking position management data Dt12 stores, in association with each other, map data of the yard YRD, information on each parking area PAR1 to PAR5 within the yard YRD, information on the multiple parking spaces included in each parking area PAR1 to PAR5 (e.g., the location of the parking space, an identification number that identifies the parking space, etc.), and information on the parking position and movement route for each trailer TR determined by the parking position schedule unit 114.

[0048] In addition, if the stopping position schedule unit 114 determines that the trailer TR has exited the yard YRD based on the captured image taken by the camera CM1, it may delete information about the stopping position and movement route of the exiting trailer TR from the trailer stopping position management data Dt12.

[0049] The memory 12 includes a read-only memory (hereinafter referred to as "ROM") and a random access memory (hereinafter referred to as "RAM"). The ROM stores programs that define the processing (operations) of the processor 11, and data that is referenced when the programs are executed. The RAM is a work memory used when the processor 11 executes the processing (operations), and temporarily stores data or information generated or acquired in each process. The memory 12 also stores map data within the yard YRD, a trailer arrival time management table Dt11, trailer parking position management data Dt12, etc.

[0050] The monitor MN is configured using, for example, a Liquid Crystal Display (LCD) or an organic electroluminescence (EL). The monitor MN displays a screen that visualizes the dock usage schedule table output from the dock schedule management unit 113. The monitor MN also outputs a guide screen SC (see FIG. 10) that visualizes information on stop positions and travel routes output from the stop position schedule unit 114.

[0051] Next, a method for calculating the exit time of each trailer TR and a method for managing the usage schedule of each dock will be described with reference to Fig. 4 and Fig. 5. Fig. 4 is a diagram for explaining a method for calculating the exit time of each trailer TR. Fig. 5 is a diagram for explaining a method for managing the usage schedule of each dock. Note that, for ease of understanding, Fig. 5 describes an example in which the number of dock ports is two, but the present invention is not limited to this.

[0052] The memory 12 stores information on the maximum waiting time that the trailer TR will stay in the yard YRD, which is set for each type of cargo. The maximum waiting time is set in advance based on the deadline (priority) corresponding to the type of cargo, and is set, for example, as 1 hour for ice cream, 1.5 hours for groceries, or 2 hours for electronic components.

[0053] The dock schedule management unit 113 calculates and sets the exit deadline time for the trailer TR to exit the yard YRD based on the predicted arrival time of the trailer TR (i.e., the predicted entry time for entry into the yard YRD) and the type of cargo on the trailer TR. The dock schedule management unit 113 sets the arrival time (entry time) as the start time and calculates the exit deadline time as the time obtained by adding the work time required for loading or unloading and the longest waiting time.

[0054] In this way, the terminal device P1 effectively prevents trailers TR with long deadlines for loading or unloading cargo from being left in a waiting state within the yard YRD. Based on the calculated exit deadlines for each trailer TR, the dock schedule management unit 113 determines the priority of the trailers TR so that loading or unloading is performed in order of the earliest exit deadline.

[0055] For example, in the example shown in FIG. 4, the dock schedule management unit 113 acquires information on the arrival time (prediction) of each of trailers ID1 to ID6 output from the trailer arrival time management unit 112. The exit deadline time TL1 is the exit deadline time of the trailer TR having the trailer ID "ID1". The exit deadline time TL2 is the exit deadline time of the trailer TR having the trailer ID "ID2". The exit deadline time TL3 is the exit deadline time of the trailer TR having the trailer ID "ID3". The exit deadline time TL4 is the exit deadline time of the trailer TR having the trailer ID "ID4". The exit deadline time TL5 is the exit deadline time of the trailer TR having the trailer ID "ID5". The exit deadline time TL6 is the exit deadline time of the trailer TR having the trailer ID "ID6". Furthermore, each of the horizontal bar graphs TM11, TM12, TM13, TM14, TM15, and TM16 shown in FIG. 4 indicates the luggage handling time relative to the total time length (stay time) between the entry time (prediction) and the exit deadline time of the trailer TR corresponding to the trailer ID.

[0056] The dock schedule management unit 113 determines the priority of the trailers TR in the order of "ID1," "ID2," "ID3," "ID4," "ID5," and "ID6," in order of earliest exit deadline times TL1 to TL6, and queues the loading or unloading work (i.e., tasks) for the trailers TR in order of highest priority.

[0057] The dock schedule management unit 113 allocates the loading or unloading work of the queued trailers TR to each dock based on the availability information of the docks transmitted from the warehouse management system MS3.

[0058] 5, the dock schedule management unit 113 generates a dock usage schedule management table in which cargo with trailer IDs "ID1," "ID3," and "ID5" are loaded or unloaded at the dock port corresponding to "Dock 1," and cargo with trailer IDs "ID2," "ID4," and "ID6" are loaded or unloaded at the dock port corresponding to "Dock 2." Bar graph TM21 indicates the work time for each trailer TR performed at "Dock 1." Bar graph TM22 indicates the work time for each trailer TR performed at "Dock 2."

[0059] Here, the work time TM221 for trailer ID "ID6" shown in FIG. 5 exceeds the exit deadline TL6 for trailer ID "ID6." However, the exit deadline in the present disclosure is a provisional deadline to prevent the waiting time of trailer TR from becoming redundant, and is a deadline different from the actual exit deadline for trailer TR. Therefore, even if the dock schedule management unit 113 in the present disclosure determines a dock usage schedule by prioritizing the efficiency of loading or unloading all cargoes that are carried out in the entire yard YRD, it can determine a dock usage schedule that does not miss the deadline for the cargoes or the true exit deadline for trailer TR.

[0060] Next, a method for determining the stopping position and movement route of a trailer TR will be described with reference to Fig. 6 to Fig. 9. Fig. 6 is a flowchart showing an example of an operation procedure of the terminal device P1 according to the embodiment. Fig. 7 is a flowchart showing an example of a procedure for determining the stopping position of the terminal device P1 according to the embodiment. Fig. 8 is a diagram explaining a first calculation example of the weights of the divided blocks DV1, DV2, DV3, DV4, DV5, DV6, DV7, and DV8. Fig. 9 is a diagram explaining a second calculation example of the weights of the divided blocks DV1 to DV9.

[0061] The character recognition unit 111 acquires a captured image captured by the camera CM1. The character recognition unit 111 detects the license plate of the trailer TR from the captured image and performs character recognition to acquire the license plate (NP) of the trailer TR and information on the trailer ID of the trailer TR identified by the license plate information (St11). The trailer ID may be identification information of the trailer TR shared throughout the logistics management system 100, or may be identification information of the trailer TR shared only within each base (yard). Furthermore, if the trailer ID is identification information shared throughout the logistics management system 100, the trailer ID may be information obtained by reading a two-dimensional code attached to the trailer TR itself or by analyzing characters (symbols), etc.

[0062] The character recognition unit 111 compares the license plate acquired by character recognition by the camera CM1 with the license plate that was previously transmitted from the transportation and delivery management system MS2 and stored in the trailer arrival time management table Dt11, and links the acquired trailer ID information to the matched license plate (St12). Note that if the information on the license plate to be linked is not stored in the trailer arrival time management table Dt11, the information on the trailer TR may be stored manually by the manager who manages the entry and exit of trailers TR at gate GT.

[0063] The dock schedule management unit 113 acquires availability information for docks DCK1 to DCK8 of warehouse WH in yard YRD transmitted from the warehouse management system MS3. The dock schedule management unit 113 generates a dock usage schedule table for trailers TR that are stored in the trailer arrival time management table Dt11 and for which the scheduling of loading or unloading work of cargo has not been completed, based on the availability information for docks DCK1 to DCK8, the arrival time (predicted), the type of cargo, and the longest waiting time of the trailer TR.

[0064] The stop position schedule unit 114 acquires the dock usage schedule table generated by the dock schedule management unit 113 (St13).

[0065] The stopping position schedule unit 114 acquires the position of the dock port to be used by the trailer TR based on the dock usage schedule. The stopping position schedule unit 114 refers to the trailer stopping position management data Dt12 and acquires information on the stopping positions of all trailers TR currently entering the yard YRD (St14).

[0066] The stopping position schedule unit 114 executes a process to determine the stopping position of the trailer TR based on the acquired position of the dock port used by the trailer TR and the stopping positions of all trailers TR currently entering the yard YRD (St15).

[0067] The stopping position scheduler 114 searches for N consecutive vacant parking spaces based on parking spaces not being used as stopping positions for the trailer TR (hereinafter referred to as "vacant parking spaces") and the size of the current division block (= N (N: an integer equal to or greater than 1)), and divides the N consecutive vacant parking spaces into one division block (St151). Note that the division block here is a candidate for a stopping position for the trailer TR. In the present disclosure, the maximum value of the size N of the division block may be set to any value. In order to facilitate the stopping operation of the trailer TR, it is desirable for the size N of the division block to be N=8, which is close to the length of one trailer TR in the forward / reverse direction (≈24 m), but is not limited to this.

[0068] For example, when N=4, the stopping position scheduler 114 searches for a parking space with four consecutive vacant spaces and divides the four consecutive vacant spaces into one divided block. In the example shown in Fig. 8, the stopping position scheduler 114 divides the parking space into eight divided blocks DV1 to DV8.

[0069] The stop position scheduler 114 determines whether the number of divided blocks generated by the division is one or more (St152).

[0070] If the stop position schedule unit 114 determines in step St152 that the number of divided blocks is one or more (St152, YES), it calculates the shortest distance between each divided block and the dock used by the trailer TR (the location of dock port DCK21) and the travel time r (St153).

[0071] The shortest distance here refers to the distance (length) along the travel routes RT11, RT12, RT13, and RT14 along which the trailer TR travels, connecting the center position DV11 of one of the four sides of the rectangular divided block that faces the road along which the trailer TR travels and the dock used by the trailer TR (the position of the dock port DCK21). Furthermore, the travel time r is the time required for the trailer TR to travel along the travel routes RT11 to RT14. Note that in FIG. 8, only the center position of the divided block DV1 is shown.

[0072] On the other hand, if it is determined in step St152 that the number of divided blocks is not 1 or more (St152, NO), the stop position schedule unit 114 decrements the current value of N by N=N-1 (St154) and returns to step St151.

[0073] The stopping position scheduler 114 determines whether there is a collision (intersection) with the movement path (flow line) of another trailer TR11 on the movement path RT11-RT14 between each of the divided blocks DV1-DV8 and the dock (location of dock port DCK21) used by the trailer TR. Specifically, the stopping position scheduler 114 determines whether there is a movement path (flow line) of another trailer TR11 within M (M: integer) minutes (e.g., any time before, such as 20 minutes or 30 minutes) immediately before the time when the trailer TR uses the dock (dock port DCK21). If the stopping position scheduler 114 determines that there is a movement path (flow line) of another trailer TR11 within M minutes immediately before the time when the trailer TR uses the dock, it further calculates a waiting time c for waiting at the divided block to avoid a collision with the movement path (flow line) of the other trailer TR11 (St155).

[0074] 9, the movement routes RT12-RT13 of the divided blocks DV2-DV3 collide (intersect) with the movement route RT10 (traffic line) along which another trailer TR11 moves to the dock (dock port DCK22). In such a case, the stop position scheduler 114 calculates the waiting time c for waiting in each of the divided blocks DV2 and DV3 so that the movement routes RT12-RT13 do not collide with the movement route RT10 during the M minutes immediately before the trailer TR uses the dock.

[0075] The stop position scheduler 114 calculates a weight w for determining the stop position of the trailer TR using the dock (dock port DCK21) in one of the divided blocks based on the travel time r and waiting time c of each of the divided blocks DV1 to DV8. i =gx(r,c) is calculated for each divided block (Step 156).

[0076] The stop position scheduler 114 calculates the weights w of the divided blocks DV1 to DV8. i The divided block with the smallest value is determined as the divided block where the trailer TR will stop (St157).

[0077] 8 and 9, the stop position scheduler 114 calculates a weight w1 for divided block DV1, a weight w2 for divided block DV2, a weight w3 for divided block DV3, and a weight w4 for divided block DV4. In the example shown in FIG. 8, the magnitude relationship between the weights is w1>w3>w4>w2. In such a case, the stop position scheduler 114 determines the divided block DV2 corresponding to the weight w2, which is the smallest value among the calculated weights w1 to w4, as the divided block where the trailer TR will stop. Also, in the example shown in FIG. 9, the magnitude relationship between the weights is w3>w2>w1>w4. In such a case, the stop position scheduler 114 determines the divided block DV4 corresponding to the weight w4, which is the smallest value among the calculated weights w1 to w4, as the divided block where the trailer TR will stop.

[0078] The stopping position schedule unit 114 determines whether the travel time (= travel time r + waiting time c) of the trailer TR between the division block determined as the stopping position of the trailer TR and the dock (dock port DCK21) is less than the upper limit time allowed for the travel time of the trailer TR (St158).

[0079] If the stopping position schedule unit 114 determines in step St158 that the travel time of the trailer TR is equal to or less than the upper limit time allowed for the travel time of the trailer TR (St158, YES), it terminates the process of determining the stopping position of the trailer TR (step St15).

[0080] On the other hand, when the stopping position scheduler 114 determines in step St158 that the travel time of the trailer TR is not equal to or less than the upper limit time allowed for the travel time of the trailer TR (St158, NO), the process returns to step St151.

[0081] The stop position scheduler 114 determines the movement route of the trailer TR from the gate GT to the divided block based on the determined stop position (divided block).

[0082] Specifically, the stop position schedule unit 114 generates candidates for movement routes from the gate GT to the stop position (division block). The stop position schedule unit 114 determines one of the movement routes (for example, movement route RT32 shown in FIG. 10) that will take the shortest time for the trailer TR to move to the stop position, based on the movement route from the gate GT to the stop position (division block) and the movement routes (flow lines) of other trailers within K (K: integer) minutes (for example, any time such as 20 minutes or 30 minutes before) before and after the arrival time (prediction) of the trailer TR.

[0083] The stop position scheduler 114 generates a guide screen SC (see FIG. 10) including information on the determined stop positions (divided blocks) of the trailer TR and the travel route, and outputs it to the monitor MN (St16).

[0084] If there are multiple candidate parking spaces for the trailer TR to park based on the parking position (divided block) of the trailer TR shown on the guidance screen SC, that is, if the size of the divided block is N≧2 or more, the administrator designates any one of the parking spaces included in the divided block as the parking position of the trailer TR.

[0085] The stop position schedule unit 114 associates the stop position of the trailer TR designated by the administrator, information on the travel route between the stop position and the dock (dock port), the travel route from the gate GT to the stop position, and the identification information of this trailer TR (trailer ID, license plate, etc.) in the trailer stop position management data Dt12. Note that when the arrival time (prediction) of the trailer TR is updated based on traffic information, weather information, etc., the travel route may be changed based on the updated arrival time (prediction) of the trailer TR.

[0086] Furthermore, in step St155 described above, if the stop position schedule unit 114 determines that no other trailers are scheduled to use the dock (dock port) used by the trailer TR at the (predicted) arrival time of the trailer TR and that the dock (dock port) is available at the (predicted) arrival time of the trailer TR, the stop position schedule unit 114 may set the stop position after entering the gate GT to the position of the dock (dock port) that is scheduled to be used. In such a case, the stop position schedule unit 114 determines the movement route of the trailer TR moving between the gate GT and the position of the dock (dock port). The stop position schedule unit 114 generates a guide screen SC including the position of the dock (dock port) as the determined stop position and information on the movement route from the gate GT to the dock (dock port), and outputs the screen to the monitor MN.

[0087] As described above, the terminal device P1 in the embodiment can schedule the trailer TR to use the dock (dock port), i.e., can streamline the loading or unloading of cargo on each trailer TR, based on the type of cargo on the trailer TR, the working time based on the type of cargo, or the deadline for exit, etc.

[0088] Furthermore, the terminal device P1 can improve the efficiency of movement of the trailer TR between the stopping position and the dock (dock port) based on the dock (dock port) used by the trailer TR, the available space in the parking area during the dock usage time, and the movement routes of other trailers during the M minutes immediately prior to the dock usage time. Similarly, the terminal device P1 can improve the efficiency of the movement route of the trailer TR from the gate GT to the stopping position based on the determined stopping position and the (predicted) arrival time of the trailer TR.

[0089] As a result, the terminal device P1 in the embodiment can suggest a stopping position for the trailer TR, and can make loading or unloading work more efficient.

[0090] Next, a guide screen SC that notifies the manager or driver of the trailer TR's stopping position and travel route will be described with reference to Fig. 10. Fig. 10 is a diagram showing an example of the guide screen SC. Note that the guide screen SC shown in Fig. 10 is just an example and is not limited to this. Also, in Fig. 10, in order to make the explanation easier to understand, a guide screen SC that has been generated by cutting out a portion of the map data of the yard YRD is shown.

[0091] The guidance screen SC is generated by the stop position schedule unit 114 and is output to and displayed on the monitor MN. The guidance screen SC may be transmitted to and displayed on a car navigation system or a tablet terminal mounted on the tractor that tows the trailer TR.

[0092] The guidance screen SC includes, on the map data of the yard YRD, the position of the gate GT, the stopping position DV31, and the movement route RT32 from the gate GT to the stopping position DV31.

[0093] When the stopping position DV31 is determined as the stopping position of the trailer TR based on the administrator's operation, the stopping position schedule unit 114 generates movement routes RT31, RT32 from the gate GT to the stopping position (divided block). The stopping position schedule unit 114 determines whether the generated movement routes RT31, RT32 collide (intersect) with the movement route (traffic line) of another trailer within K minutes (for example, any time such as 20 minutes or 30 minutes before) before or after the arrival time (prediction) of the trailer TR.

[0094] 10, the stop position schedule unit 114 determines that when a trailer TR moves along movement route RT31, its movement route (traffic line) will collide (intersect) with another trailer at waiting position Pt31. The stop position schedule unit 114 calculates the waiting time for waiting for the other trailer to pass, and calculates the travel time when the trailer moves to stop position DV31 along movement route RT31 and the travel time when the trailer moves to stop position DV31 along movement route RT32, including the calculated waiting time.

[0095] In the example shown in FIG. 10, if the stop position scheduler 114 determines that the travel time of the movement route RT31 is shorter than that of the movement route RT32, the guide screen SC is generated on the map data of the yard YRD, superimposing the position of the gate GT, the stop position DV31, the movement route RT31 from the gate GT to the stop position DV31, and the waiting position Pt31, which is a position where the trailer TR collides (intersects) with the movement route of another trailer and where the trailer TR waits for the other trailer to pass. Note that in the example shown in FIG. 10, because the waiting position Pt31 is located near the stopping position DV31, the destination position indicated by the tip of the arrow of the movement route RT31 is not illustrated up to the stopping position DV31. However, for example, if the stopping position DV31 is not near the waiting position Pt31, an arrow indicating the movement route from the waiting position Pt31 to the stopping position DV31 may also be illustrated. In such a case, the information on the movement route RT32 is omitted from the guide screen SC.

[0096] 10, if the stop position scheduler 114 determines that the travel time for the movement route RT32 is shorter than that for the movement route RT31, it generates a guidance screen SC in which the position of the gate GT, the stop position DV31, and the movement route RT32 from the gate GT to the stop position DV31 are superimposed on the map data of the yard YRD. In this case, information on the movement route RT31 and the waiting position Pt31 is omitted from the guidance screen SC.

[0097] 10, the guide screen SC may include character information indicating the location information of the parking position DV31 or the dock (dock port DCK31), although this is not shown. The character information here is, for example, the name and number of the parking area corresponding to the parking position DV31 (parking space), the name and number of the parking space, or the name and number of the dock corresponding to the dock port DCK31, the name and number of the dock port DCK31, etc.

[0098] This allows the terminal device P1 to assist the manager in instructing the driver on the stopping position of the trailer TR and the route of the trailer TR from the gate GT to the stopping position.
