Description

[Technical field]

[0001] The present invention relates to a technique for transporting luggage using a moving object. [Background technology]

[0002] According to the Automobile Transportation Business Law issued by the Ministry of Health, Labor and Welfare's Labor Standards Bureau, a driver's driving time per day must not exceed 9 hours, and a driver's working hours per day must not exceed 13 hours.

[0003] Moreover, in recent years, the transportation industry has been facing a serious shortage of drivers, and in order to alleviate this, there is a demand to reduce the driving distances of individual drivers and improve working conditions.

[0004] Taking these circumstances into consideration, Patent Document 1 discloses a transportation system that includes a first truck vehicle that travels between a first area and a transshipment / relay point, and a second truck vehicle that travels between a second area and the transshipment / relay point, in which the first truck vehicle and the second truck vehicle transfer cargo to each other at the transshipment / relay point, and after that, the first truck vehicle returns to the first area and the second truck vehicle returns to the second area.

[0005] [Patent Document 1] Patent No. 6279631 Summary of the Invention [Problem to be solved by the invention]

[0006] However, since the above-mentioned transportation system has only one transshipment / relay point, when applied to cargo that needs to be transported long distances, a problem arises in that the driving distances of the drivers of both the first truck vehicle and the second truck vehicle become long.

[0007] The present invention is devised to solve such problems, and aims to provide a technology that can efficiently transport cargo over long distances without increasing the driving distance per driver. [Means for solving the problem]

[0008] (1) A transportation management device in one embodiment of the present invention is a transportation management device that manages a transportation system that transports multiple pieces of luggage, including a first piece of luggage transported in a first direction via a plurality of transfer and relay points, and a second piece of luggage transported in a second direction opposite to the first direction via the plurality of transfer and relay points, wherein the multiple pieces of luggage are transported while being transshipped at the plurality of transfer and relay points by a plurality of moving bodies that travel back and forth between adjacent points, and a processor of the transportation management device obtains a first estimated arrival time of the first moving body transporting the first piece of luggage and a second estimated arrival time of a second moving body transporting the second piece of luggage at each transshipment and relay point, and at each transshipment and relay point, determines a target moving body that will transfer luggage between the first moving body and the second moving body from among the second moving bodies whose second estimated arrival time is within a set time of the first estimated arrival time.

[0009] According to this configuration, a transportation system can be constructed in which a plurality of moving bodies traveling between adjacent points transport the first and second packages while transferring them at a plurality of transfer / relay points. Here, at each transfer / relay point, a target moving body that transfers packages between the first moving body and the second moving body is determined from among the second moving bodies that are within a set time from the first scheduled arrival time. Therefore, a transportation system can be constructed that efficiently transports packages that have long transportation distances without increasing the driving distance per driver.

[0010] (2) In the above transportation management device, the target moving body may be a second moving body that satisfies a transportation condition that the next transportation point of a second package transported by the second moving body to a target transhipment / relay point coincides with a point passed by the first moving body just before the target transhipment / relay point.

[0011] According to this configuration, the first and second packages can be transported to the delivery point efficiently.

[0012] (3) In the above transportation management device, the multiple moving bodies may include a removable cargo platform, and the transfer may involve attaching the cargo platform of the first moving body to the target moving body and attaching the cargo platform of the target moving body to the first moving body.

[0013] According to this configuration, the cargo can be transferred without removing the cargo from the loading platform.

[0014] (4) In the transportation management device, the first moving object and the target moving object may be moving objects having the same platform type.

[0015] According to this configuration, it is possible to prevent the loading platforms of the first and target moving bodies from becoming different types of loading platforms after the luggage is transferred.

[0016] (5) In the above transportation management device, the sojourn time of the first moving body at each transfer / relay point may be obtained, and the sojourn time may include a first half period from the first scheduled arrival time to a specified time and a second half period after the specified time, the first half period being the set time, and the second half period being the required transfer time required for transshipment of cargo.

[0017] According to this configuration, the first and second moving bodies can secure the time required for transferring luggage.

[0018] (6) A transportation management method in another aspect of the present disclosure is a transportation management method for managing a transportation system that transports a plurality of parcels, including a first parcel transported in a first direction via a plurality of transfer and relay points, and a second parcel transported in a second direction opposite to the first direction via the plurality of transfer and relay points, wherein the plurality of parcels are transported while being transshipped at the plurality of transfer and relay points by a plurality of moving bodies that travel back and forth between adjacent points, and a computer acquires a first estimated arrival time of the first moving body transporting the first parcel and a second estimated arrival time of a second moving body transporting the second parcel at each transfer and relay point, and at each transfer and relay point, determines a target moving body that will transfer parcels between the first moving body and the second moving body from among the second moving bodies whose second estimated arrival time is within a set time of the first estimated arrival time.

[0019] According to this configuration, a transportation management method is provided that can efficiently transport cargo over long distances without increasing the driving distance per driver. Effect of the Invention

[0020] According to the present invention, cargo that needs to be transported long distances can be transported efficiently without increasing the driving distance per driver. [Brief description of the drawings]

[Figure 7] 13 is a flowchart showing details of a determination process. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Fig. 1 is an overall configuration diagram of a transportation management system 1 in an embodiment of the present invention. The transportation management system 1 includes a transportation management device 10 and multiple terminals 20. The transportation management device 10 is a device that manages the operation of mobile objects by the transportation system. The transportation system is a transportation system in which multiple mobile objects traveling between adjacent transfer and relay points transport multiple packages while transferring them at multiple transfer and relay points.

[0023] FIG. 2 is a diagram showing an example of a transportation system in this embodiment. This transportation system includes two shipping points N1 and N6, three transshipment and relay points N2 to N4, and two delivery points N5 and N7. The shipping point N1 is the shipping point of the package R1, and the delivery point N5 is the delivery point of the package R1. The shipping point N6 is the shipping point of the package R2, and the delivery point N7 is the delivery point of the package R2. That is, the package R1 is a package transported in a first direction D1 from the shipping point N1 toward the delivery point N5 through the transshipment and relay points N2 to N4 in this order. The package R2 is a package transported in a second direction D2 from the shipping point N6 toward the delivery point N7 through the transshipment and relay points N4 to N2 in this order.

[0024] Mobile body M1 is a mobile body that departs from shipping point N1 and heads toward delivery point N7 via transhipment / relay point N2. Mobile body M2 is a mobile body that travels back and forth between transhipment / relay point N2 and transhipment / relay point N3. Mobile body M3 is a mobile body that travels back and forth between transhipment / relay point N3 and transhipment / relay point N4. Mobile body M4 is a mobile body that departs from transhipment / relay point N4 and heads toward delivery point N5. Mobile body M5 is a mobile body that departs from shipping point N6 and heads toward transhipment / relay point N4.

[0025] Each of the transshipment / relay points N2 to N4 is a location where cargo is transshipped between a mobile body transporting cargo R1 and a mobile body transporting cargo R2. The transshipment / relay points N2 to N4 are locations that are set up in advance by a transport company that operates the transport system. The transshipment / relay points N2 to N4 include transshipment / relay points that have a garage and transshipment / relay points that do not have a garage. In this example, the transshipment / relay points N2 and N4 are transshipment / relay points that include a garage, and the transshipment / relay point N3 is a transshipment / relay point that does not include a garage. Therefore, the transshipment / relay point N2 is a garage for the mobile bodies M1 and M2, and the transshipment / relay point N4 is a garage for the mobile bodies M3 and M4.

[0026] Each of the mobile bodies M1 to M4 is composed of a transport truck with a removable loading platform. When the luggage is transported from the shipping point to the delivery point, the loading platform is transported together with the luggage. Therefore, at each of the transshipment / relay points N2 to N4, the luggage is transshipped by replacing the loading platform without being taken out of the loading platform. For example, at the transshipment / relay point N2, the loading platform of the mobile body M1 is removed from the mobile body M1 and the removed loading platform is attached to the mobile body M2, and the loading platform of the mobile body M2 is removed from the mobile body M2 and the removed loading platform is attached to the mobile body M1, thereby transshipping the luggage R1 and the luggage R2.

[0027] Returning to Fig. 1, the transportation management device 10 is configured, for example, by a cloud server. The terminals 20 are configured by computers corresponding to each of the multiple mobile objects. The terminals 20 may be configured by in-vehicle terminals, or may be configured by portable computers such as smartphones or tablet computers. The transportation management device 10 and the multiple terminals 20 are connected to each other so as to be able to communicate with each other via a network NT. The network NT is configured by a wide area communication network including the Internet communication network and a mobile phone communication network.

[0028] The transportation management device 10 includes a processor 11, a memory 12, a communication device 13, and an input device 14. The processor 11 is configured with a central processing unit (CPU). The memory 12 is configured with a non-volatile rewritable storage device such as a hard disk drive (HDD) or a solid state drive (SSD). The memory 12 includes a vehicle data storage unit 121, a baggage data storage unit 122, and an allocation data storage unit 123.

[0029] The vehicle data storage unit 121 stores vehicle data, which is data related to vehicles used in the transportation system. FIG. 3 is a configuration diagram of the vehicle data storage unit 121. The vehicle data storage unit 121 has a tabular data structure in which one vehicle data is assigned to one record. The vehicle data includes a vehicle ID, a point-to-point ID, a terminal ID, and a loading platform type ID. The vehicle ID is an identifier of the moving body. The point-to-point ID is an identifier of the adjacent points that the moving body is responsible for transporting. For example, the moving body with the vehicle ID "M11" is responsible for the point-to-point between the transshipment / relay point N2 and the shipping point N1, so "N2⇔N1" is set as the point-to-point ID. In the point-to-point ID, the symbol on the left side of the arrow indicates the transshipment / relay point that becomes a garage. For example, the moving body with the vehicle ID "M21" is responsible for the point-to-point between the transshipment / relay point N2 and the transshipment / relay point N3, and since the garage is the transshipment / relay point N2, "N2⇔N3" is set as the point-to-point ID.

[0030] The terminal ID is an identifier of the terminal 20 corresponding to the moving object. For example, since the moving object with the vehicle ID "M11" corresponds to the terminal 20 with the terminal ID "T011", "T011" is set as the terminal ID.

[0031] The loading platform type ID is an identifier that indicates the type of loading platform that is attached to the moving body. For example, the loading platform type ID of the moving body with the vehicle ID "M11" is set to "A" because the loading platform type is A. Types of loading platforms include a type in which the roof and sides open, and a type in which only the rear end opens.

[0032] The luggage data storage unit 122 stores luggage data related to luggage to be transported in the transport system. FIG. 4 is a configuration diagram of the luggage data storage unit 122. The luggage data storage unit 122 has a tabular data structure in which one piece of luggage data is assigned to one record. The luggage data includes a luggage ID, a shipper ID, a shipping point, a delivery point, a desired arrival time, and an order time. The luggage ID is an identifier that uniquely identifies a luggage. The shipper ID is an identifier of the person who requested the transportation of the luggage. The shipping point is the shipping point of the luggage. The delivery point is the delivery point of the luggage. The desired arrival time is the desired arrival time of the luggage. The desired arrival time includes a date and a time. The order time is the time when the request to transport the luggage was received. The order time includes a date and a time. The package with package ID "R11" has a shipper ID of "BB1", a shipping point of N1, a delivery point of N5, a desired arrival time of P1:00 on Z1 / Y1 / X1, and an order time of P2:00 on Z2 / Y2 / X2, so these data are set in the package data corresponding to this package.

[0033] The allocation data storage unit 123 stores allocation data in which a load to be transported is allocated to each moving body. FIG. 5 is a data configuration diagram of the allocation data storage unit 123. The allocation data storage unit 123 has a tabular data configuration in which one allocation data is allocated to one record. The allocation data includes a vehicle ID, a load ID, a travel route, and an estimated arrival time. The vehicle ID and the load ID are the same as those described above. The travel route indicates from which point to which the load is to be transported. The estimated arrival time is the estimated arrival time at the transportation point of the destination indicated by the travel route. For example, a moving body with a vehicle ID "M1" transports a load with a load ID "R1" from a shipping point N1 to a transfer / relay point N2, and the estimated arrival time at the transfer / relay point N2 is "19:30 on November 1, 2023", so this information is set in the allocation data storage unit 123.

[0034] Returning to Fig. 1, the communication device 13 communicates with the terminals 20 via the network NT. For example, the communication device 13 transmits notification information for notifying each terminal 20 of a target moving object that is a target for transshipment of luggage.

[0035] The input device 14 is composed of a keyboard, a mouse, etc., and accepts input instructions from an operator. An example of an input instruction is an instruction to input luggage data. When an operator receives a request to transport luggage, the operator inputs luggage data related to the luggage using the input device 14. The input luggage data is stored in the luggage data storage unit 122. In this manner, luggage data is accumulated in the luggage data storage unit 122.

[0036] Fig. 6 is a flowchart showing the processing of the transportation management device 10. In step S1, the processor 11 acquires parcel data to be processed from the parcel data storage unit 122. For example, the processor 11 executes the processing shown in Fig. 6 on a daily basis. Therefore, at a predetermined processing time, the processor 11 may acquire parcel data of parcels that have been ordered within the period from the creation time up to 24 hours prior from the parcel data storage unit 122 as parcel data to be processed.

[0037] In step S2, the processor 11 acquires the desired arrival time at the delivery point for each package to be processed. Here, the processor 11 may acquire the desired arrival time from the package data acquired in step S1.

[0038] In step S3, the processor 11 acquires an estimated travel time between adjacent points for each piece of luggage indicated by the luggage data acquired in step S1. Here, it is assumed that each piece of luggage is transported along either the route in the first direction D1 or the route in the second direction D2 shown in Fig. 2. Therefore, the adjacent points are between the shipping point N1 and the transshipment / relay point N2, between the transshipment / relay point N2 and the transshipment / relay point N3, between the transshipment / relay point N3 and the transshipment / relay point N4, between the transshipment / relay point N4 and the delivery point N5, between the shipping point N6 and the transshipment / relay point N4, and between the transshipment / relay point N2 and the delivery point N7.

[0039] The memory 12 stores the estimated travel times between these adjacent points in advance. Therefore, the processor 11 may acquire the estimated travel times between the adjacent points from the memory 12. Alternatively, the processor 11 may acquire the estimated travel times between the adjacent points by inputting the position information of each of the shipping points N1, N6, the delivery points N5, N7, and the transfer / relay points N2 to N4 into a route search system. The route search system may be included in an external computer connected to the network NT, or may be included in the transportation management device 10.

[0040] In step S4, the processor 11 calculates the scheduled departure time for each shipment point and each transshipment / relay point and the scheduled arrival time for each transshipment / relay point based on the desired arrival time and the estimated travel time for each shipment to be processed so that the shipment arrives at the delivery point by the desired arrival time. The scheduled arrival time is a time a predetermined stay time before the scheduled departure time.

[0041] Please refer to Figure 2. The desired arrival time for package R1 at delivery point N5 is 8:00. In the example of Figure 2, the estimated travel time between adjacent points is all 4 hours. In the example of Figure 2, the stay time at each point is 30 minutes. Using this information, processor 11 calculates the scheduled departure time for package R1 from the shipping point N1 and each of the transshipment / relay points N2 to N4, and the scheduled arrival time for package R1 at each of the transshipment / relay points N2 to N4, by going back from the downstream side to the upstream side in the first direction D1.

[0042] In detail, 4:00, four hours before the scheduled arrival time of 8:00, is calculated as the scheduled departure time of the luggage R1 at the trans-shipment / relay point N4. 30:30, 30 minutes before 4:00, is calculated as the scheduled arrival time of the luggage R1 at the trans-shipment / relay point N4. 23:30, four hours before 3:30, is calculated as the scheduled departure time of the luggage R1 at the trans-shipment / relay point N3. 23:00, 30 minutes before 23:30, is calculated as the scheduled arrival time of the luggage R1 at the trans-shipment / relay point N3. Similarly, the scheduled departure times of the luggage R1 at each of the trans-shipment / relay point N2 and the shipping point N1, and the scheduled arrival time of the luggage R1 at the trans-shipment / relay point N2 are calculated. As with the luggage R1, the scheduled departure times of the luggage R2 at each of the shipping point N6 and the trans-shipment / relay points N2 to N4, and the scheduled arrival times at the trans-shipment / relay points N2 to N4 are calculated for the luggage R2. For ease of explanation, only two packages R1 and R2 are shown in FIG. 2, but for the other packages to be processed, the scheduled departure times for each of the shipping points and transshipment / relay points N2 to N4 and the scheduled arrival times for each of the transshipment / relay points N2 to N4 are calculated in the same manner as for packages R1 and R2.

[0043] In step S5, the processor 11 generates allocation data by allocating a mobile unit that transports each piece of luggage between each point, and stores the allocation data in the allocation data storage unit 123. For example, the processor 11 allocates a mobile unit that transports each piece of luggage to be processed in order from among the mobile units responsible for transportation between each point. In this case, the allocation data includes the scheduled departure time calculated for each piece of luggage in step S4 and the scheduled arrival time at each transfer / relay point.

[0044] In step S6, the processor 11 acquires from the allocation data storage unit 123 the first estimated arrival time of the first moving body transporting the first package and the second estimated arrival time of the second moving body transporting the second package at each transhipment / relay point. In the example of FIG. 5, the moving body with the vehicle ID "M1" corresponds to the first moving body that moves the first package (package R1) from the shipping point N1 to the transhipment / relay point N2, and the estimated arrival time "2023 / 11 / 1 / 19:30" corresponds to the first estimated arrival time. Also, in the example of FIG. 5, the moving body with the vehicle ID "M2" corresponds to the second moving body that moves the second package (package R2) from the transhipment / relay point N3 to the transhipment / relay point N2, and the estimated arrival time "2023 / 11 / 1 / 19:45" corresponds to the second estimated arrival time.

[0045] In addition, in the example of Figure 5, the mobile object with vehicle ID "M3" corresponds to the first mobile object moving the first luggage (luggage R1) from the transshipment / relay point N3 to the transshipment / relay point N4, and the estimated arrival time "2023 / 11 / 2 / 3:30" corresponds to the first estimated arrival time.

[0046] In step S7, the processor 11 executes a determination process to determine a target moving body that will transfer cargo between the first moving body and the second moving body from among the second moving bodies whose second estimated arrival time is within a set time period of the first estimated arrival time at each transfer / relay point.

[0047] Fig. 7 is a flowchart showing the details of the determination process. In step S11, processor 11 determines one transfer / relay point of interest from among a plurality of transfer / relay points. In the example of Fig. 2, transfer / relay points N2 to N4 are determined in order as the transfer / relay point of interest.

[0048] In step S12, the processor 11 determines whether or not there is a second moving body that will arrive within a set time for a first moving body that will arrive at the target transfer / relay point N. Here, the first moving bodies are identified in order of their expected arrival times at the target transfer / relay point.

[0049] If there is a second moving body that arrives within the set time (YES in step S12), the processor 11 determines whether the second moving body satisfies a transportation condition (step S13). The transportation condition is a condition that the next transportation point of the second cargo transported by the second moving body to the target transhipment / relay point coincides with the point passed by the first moving body immediately before the target transhipment / relay point.

[0050] If the second moving object satisfies the transportation condition (YES in step S13), the processor 11 determines the second moving object as a target moving object to be transshipped (step S14).

[0051] The processing of steps S12 and S13 will be described below with reference to FIG. 2. In this example, the transshipment / relay point N3 is the transshipment / relay point of interest, the mobile unit M2 is the first mobile unit, the mobile unit M3 is the second mobile unit, the stay time T0 is 30 minutes, and the set time T1 is 15 minutes. The set time T1 is the first half of the stay time T0. The second half of the stay time T0 is the transshipment time T2. The scheduled arrival time of the mobile unit M3 transporting the cargo R2 at the transshipment / relay point N3 is 23:15. On the other hand, the scheduled arrival time of the mobile unit M2 at the transshipment / relay point N3 is 23:00. The scheduled arrival time of the mobile unit M3, 23:15, is within the set time T1 (=15 minutes) from the scheduled arrival time of the mobile unit M2, 23:00. Therefore, the mobile unit M3 satisfies the condition of step S12.

[0052] In addition, the next transportation point of the cargo R2 transported by the moving body M3 is the transshipment / relay point N2, and the transportation point immediately before that of the moving body M2 is also the transshipment / relay point N2. Therefore, the moving body M3 also satisfies the transportation condition. From the above, the moving body M3 is determined as a target moving body for the moving body M2.

[0053] If there is no second moving object that satisfies the extraction condition for the first moving object that arrives Nth (NO in step S12), or if the second moving object determined as YES in step S12 does not satisfy the transportation condition (NO in step S13), the process proceeds to step S15. In this case, the first cargo may be transported by a moving object waiting at the target transhipment / relay point.

[0054] In step S15, the processor 11 determines whether or not the processing for all first moving bodies at the target transhipment / relay point has been completed. If the processing for all first moving bodies at the target transhipment / relay point has been completed (YES in step S15), the processing proceeds to step S16. On the other hand, if the processing for all first moving bodies at the target transhipment / relay point has not been completed (NO in step S15), the processing returns to step S12. In this case, the first moving body with the next earliest estimated arrival time at the target transhipment / relay point is identified, and the processing of steps S12 to S15 is performed on this first moving body as the Nth first moving body.

[0055] In step S16, processor 11 determines whether or not processing has been completed for all transfer / relay points. If processing has been completed for all transfer / relay points (YES in step S16), processing ends. On the other hand, if processing has not been completed for all transfer / relay points (NO in step S16), processing returns to step S11. In this case, processor 11 determines the next transfer / relay point as the transfer / relay point of interest, and executes the processing of steps S12 to S15 for the determined transfer / relay point.

[0056] In this way, according to this embodiment, a transportation system can be constructed in which multiple moving bodies traveling between adjacent points transport multiple packages while transferring packages at multiple transfer / relay points. Here, at each transfer / relay point, a target moving body that transfers packages between the first moving body and the second moving body that is within a set time from the first scheduled arrival time is determined. Therefore, packages that have long transportation distances can be transported efficiently without increasing the driving distance per driver.

[0057] The present invention can employ the following modifications.

[0058] (1) In the example of FIG. 2, the delivery point N5 of the package R1 may be the same as the shipping point N6 of the package R2.

[0059] (2) In the example of FIG. 2, the delivery point N7 of the package R2 may be the same as the shipping point N1 of the package R1.

[0060] (3) In the example of Figure 2, the number of transshipment and relay points is three, but this is just an example and there should be at least two.

[0061] (4) In the example of FIG. 2, the transfer / relay point N3 did not have a garage, but it may have one.

[0062] (5) In the example of FIG. 2, for ease of explanation, the estimated travel time between each point is set to 4 hours. However, this is merely an example and the estimated travel time may be different for each point.

[0063] (6) The transportation conditions shown in step S13 of the flowchart in Fig. 7 may further include a condition regarding the type of loading platform. The condition regarding the type of loading platform is that the type of loading platform attached to the first moving body and the type of loading platform attached to the second moving body must match.

[0064] (7) In the example of FIG. 2, the residence time at each transhipment / relay point is set to 30 minutes, but this is just an example, and the residence time may differ depending on each transhipment / relay point and each piece of luggage. For example, under the constraint that the luggage arrives at the delivery point within the desired arrival time, the residence time of each piece of luggage at each transhipment / relay point may be determined so that the residence time of each piece of luggage at each transhipment / relay point is the shortest. Processor 11 assigns a mobile unit that will transport each piece of luggage to each piece of luggage determined in this manner. Processor 11 may obtain the estimated arrival time from the transportation schedule of the mobile unit created in this manner.

[0065] (8) The processor 11 may generate a transportation plan indicating the estimated arrival time and the estimated departure time calculated at each transhipment / relay point and shipping point so as to arrive in time for the estimated arrival time for each package, and the mobile body assigned to transport each package. In this case, the processor 11 may notify each mobile body of the estimated departure time, estimated arrival time, and the transhipment / relay point or delivery point of the transport destination.
