Description

The present invention relates to technology for creating transportation plans and loading plans.

One technology for creating a transportation plan that takes into account the shape of luggage is described in JP 2010-168205 A (Patent Document 1). This publication states that "a coefficient indicating the extent to which the luggage of the unit to be delivered consumes the vehicle's loading capacity is derived using a characteristic value that has the greatest impact on the consumption of the vehicle's loading capacity among values indicating the characteristics of the luggage of the unit to be delivered" and that "an optimal vehicle allocation system characterized by comprising a vehicle allocation plan creation means for optimally allocating the luggage to the vehicle so as not to exceed the vehicle's loading capacity value."

JP 2010-168205 A

When transporting cargo of different shapes, the possible loading position may vary depending on the cargo shape, such as placing tall cargo on the driver's side. For this reason, transport companies create a transportation plan taking into account the cargo weight, and then, once the cargo to be loaded onto each vehicle has been determined, create a loading plan taking into account the cargo shape. When unloading the loaded cargo from the vehicle, it is necessary to unload the cargo in order starting from the door side of the vehicle.

When formulating transportation and loading plans, if the visiting order of the transportation plan is changed so that unloading work is performed from the door side of the vehicle to the opposite side in order to improve the efficiency of unloading work for the decided loading plan, the travel time increases and the driving burden of the transportation workers increases. On the other hand, if cargo is loaded from the door side of the vehicle to the opposite side in an order different from the visiting order, unloading and loading work is required for cargo that will not be delivered at the destination. As a result, the unloading time increases, which increases the unloading workload of the transportation workers, and also leads to increased berth occupancy time and traffic congestion. For this reason, it is desirable to formulate efficient transportation and loading plans in terms of both travel efficiency and unloading efficiency.

The system described in Patent Document 1 does not take into account the loading position, so it is not possible to evaluate unloading efficiency.

Therefore, the present invention aims to provide a technology that evaluates the trade-off between movement efficiency and unloading efficiency while taking into account the loading position restrictions imposed by the cargo shape, and simultaneously creates efficient transportation plans and loading plans.

A representative transportation planning system of the present invention for solving at least one of the above problems is as follows: A transportation planning system having a control unit and a storage unit connected to the control unit, the storage unit holds luggage information including at least the shape, destination, and transportation volume of luggage based on an order, vehicle information including information regarding the load capacity of one or more vehicles used to transport the luggage, and location information indicating multiple locations to which the luggage is to be transported, and the control unit generates multiple transportation plan proposals based on the luggage information, the vehicle information, and the location information, indicating the order in which one or more vehicles transporting luggage based on the order will arrive at each location and the luggage to be unloaded at each location, and generates a transportation plan proposal based on the luggage information, the vehicle information, and the location information, and Based on the vehicle information, multiple stowage plan proposals including the stowage positions on each vehicle for each cargo transported according to the transportation plan proposal are generated for each transportation plan proposal, a movement efficiency is calculated for each transportation plan proposal, which is an index showing the efficiency with which the vehicle moves between the multiple locations according to the transportation plan proposal, an unloading efficiency is calculated for each combination of the transportation plan proposal and the stowage plan proposal, which is an index showing the efficiency of at least the unloading work at the multiple locations, and the efficiency of the combination of the transportation plan proposal and the stowage plan proposal is calculated based on the movement efficiency and the unloading efficiency.

According to one aspect of the present invention, efficient transportation can be achieved in terms of movement efficiency and unloading efficiency, taking into account the loading position restrictions imposed by the shape of the cargo. Problems, configurations, and effects other than those described above will become clear from the explanation of the following examples.

Note that this embodiment is merely one example for realizing the present invention, and does not limit the technical scope of the present invention.

Figure 1 is a block diagram showing an example of the configuration of a transportation planning system 1 and an example of the functional configuration of a transportation planning device 100 according to Example 1.

The transportation planning system 1 includes a transportation planning device 100, an in-vehicle terminal 200 communicatively connected to the transportation planning device 100 via a network N, and a planning management terminal 300 at each collection and delivery point.

The transportation planning device 100 includes a memory unit 110, a control unit 120, an input unit 130, a display unit 140, and a communication unit 150.

The storage unit 110 stores baggage information 111, vehicle information 112, location information 113, berth information 114, movement cost information 115, evaluation information 116, transportation plan information 117, and stowage plan information 118. The baggage information 111 is information on the baggage to be transported. The baggage information 111 may include, for example, information on the shape, weight, destination, and transportation amount of the baggage based on the order. Here, the shape of the baggage may be, for example, information on the size of the baggage or information on whether or not a certain baggage can be loaded on top of another baggage. The vehicle information 112 is information on vehicles that can be used when the plan is executed. The location information 113 is information on locations such as factories. The berth information 114 is information on berths at each collection and delivery point. The movement cost information 115 is information that defines the cost required for movement between two locations. The evaluation information 116 is information on parameters that evaluate the combination of the proposed transportation plan and stowage plan. The proposed transportation plan information 117 is information on the proposed transportation plan created by the control unit 120. The proposed stowage plan information 118 is information on the proposed stowage plan created by the control unit 120.

The control unit 120 includes a transportation plan proposal creation unit 121, a stowage plan proposal creation unit 122, and a plan evaluation unit 123. The transportation plan proposal creation unit 121 generates a transportation plan proposal using the baggage information 111, the vehicle information 112, the location information 113, the berth information 114, and the movement cost information 115, and stores the transportation plan proposal in the transportation plan proposal information 117. The stowage plan proposal creation unit 122 generates a stowage plan proposal using the baggage information 111, the vehicle information 112, and the generated transportation plan proposal, and stores the stowage plan proposal in the stowage plan proposal information 118. The plan evaluation unit 123 evaluates the efficiency of the plan using the vehicle information 112, the location information 113, the evaluation information 116, and the generated transportation plan proposal and stowage plan proposal, and saves the most efficient plan among the combinations of the transportation plan proposal and the stowage plan proposal whose efficiency has been evaluated as the optimal plan.

The input unit 130 accepts input operations from the user.

The display unit 140 displays the transportation plan and stowage plan created by the control unit 120 on a display device.

The communication unit 150 transmits and receives information between the vehicle-mounted terminal 200 and the planning management terminal 300 at each collection and delivery point.

The on-board terminal 200 is mounted on the transport vehicle. The communication unit 210 receives the transport plan for each transport vehicle transmitted from the communication unit 150. The display unit 220 displays the received transport plan.

The planning management terminal 300 at each collection and delivery point is placed at each collection and delivery point. The communication unit 310 receives the transportation plan and stowage plan transmitted from the communication unit 150. The display unit 320 displays the received transportation plan and stowage plan.

Figure 2 is a block diagram showing an example of the hardware configuration of the transportation planning system 1 according to the first embodiment.

The transportation planning device 100 has a CPU (Central Processing Unit) 410, a RAM (Random Access Memory) 420, a ROM (Read Only Memory) 430, an auxiliary storage device 440, a display device 450, an input device 460, a media reading device 470, and a communication device 480. The transportation planning device 100 is capable of transmitting and receiving data between an on-board terminal 200 (not shown in FIG. 2) of a vehicle 510 and a planning management terminal 300 (not shown in FIG. 2) of a collection and delivery point 520 via the communication device 480.

The CPU 410 executes various calculations. The RAM 420 is a memory that stores programs and data executed by the CPU 410. The ROM 430 is a memory that stores programs necessary for starting the transportation planning system. The auxiliary storage device 440 is, for example, a device such as a HDD (Hard Disk Drive). The display device 450 is, for example, a device such as a liquid crystal display. The input device 460 is, for example, a device such as a keyboard that is used by a user to input information to the transportation planning device 100. The media reading device 470 is a device that reads information from a portable storage medium such as a USB (Universal Serial Bus) memory. The communication device 480 transmits and receives information to and from an external device via the network N.

For example, the control unit 120 shown in FIG. 1 is a function of the CPU 410, and the memory unit 110 is a function of the RAM 420, the ROM 430, and the auxiliary storage device 440. For example, information stored in the memory unit 110 shown in FIG. 1 is stored in the RAM 420, etc. Furthermore, the functions of each unit in the control unit 120 are realized by the CPU 410 executing a program stored in the RAM 420, etc. Furthermore, the input unit 130 shown in FIG. 1 is a function of the input device 460, the display unit 140 is a function of the display device 450, and the communication unit 150 is a function of the communication device 480.

Figure 3 is a flowchart showing an example of a process for creating a transportation plan and a stowage plan in Example 1.

The process of creating a transportation plan and a stowage plan is started, for example, when the input unit 130 accepts input. For example, information regarding a delivery order to be transported on a specific work day for which a transportation plan and a stowage plan should be created is input. When the process is started, the transportation planning device 100 reads input data from the in-vehicle terminal 200, the planning management terminal 300 at the collection and delivery point, and the input device 460 into the memory unit 110 (step S100).

Next, the transport plan creation unit 121 generates multiple transport plan candidates for when each of the one or more vehicles transports the assigned cargo, and stores them in the transport plan information 117 (step S200).

The transportation planning device 100 then performs steps S300 to S400 for all the transportation plan proposals that have been created.

In step S300, the loading plan proposal creation unit 122 generates multiple loading plan proposal candidates for each vehicle for which the cargo to be loaded has been determined in the transportation plan proposal information 117, taking into account the cargo shape, and stores the loading plan proposal for all vehicles generated by combining the loading plan proposals for each vehicle in the loading plan proposal information 118.

Specifically, the stowage plan creation unit 122 may obtain information such as the size of the luggage to be loaded onto each vehicle according to the generated transportation plan information 117 from the luggage information 111 described later, obtain the size of the bed of each vehicle from the vehicle information 112 described later, and generate the stowage plan by simulating the loading of luggage onto the bed of each vehicle. In addition to the luggage size information, the stowage plan may be created based on information on whether a certain luggage has a shape that allows other luggage to be loaded on top of it. Specifically, for example, for the candidates for the created stowage plan, it may be determined whether other luggage is loaded on top of one or more luggage that has a shape that allows other luggage to be loaded on top of it, and the candidates that are determined to have other luggage loaded on them may be excluded from the candidates for the stowage plan. Here, the vehicle information 112 may include information indicating the position of a door (i.e., an entrance/exit) for loading and unloading luggage from the bed of each vehicle. In this case, the stowage plan creation unit 122 may generate a stowage plan so that the cargo is brought in through the door position and stowed in a position on the loading platform where it can be stowed.

Then, the transportation planning device 100 performs step S400 for all the proposed loading plans that have been created.

In step S400, the plan evaluation unit 123 performs plan evaluation processing. The plan evaluation processing evaluates the combination of the proposed transportation plan and the proposed stowage plan, and saves a provisional combination of the transportation plan and the stowage plan (provisional solution).

Finally, in step S500, the transportation planning device 100 outputs the provisional solution to the display unit 140. In addition, the communication unit 150 transmits the transportation schedule to the vehicle-mounted terminal 200 and the planning management terminal 300 at each collection and delivery point via the network N.

Each step in Figure 3 is explained below.

In step S100, the memory unit 110 reads the baggage information 111, the vehicle information 112, the location information 113, the travel cost information 115, and the evaluation information 116 from the input device 460. The memory unit 110 may further read the berth information 114.

Figure 4 is a diagram showing an example of the data structure of luggage information 111 in Example 1.

Parcel information 111 includes at least the following items: an "order number" to identify the order, a "collection source code" to indicate the collection source, a "delivery destination code" to indicate the delivery destination, a "number" to indicate the number of parcels, a "length" to indicate the length of the parcel, a "width" to indicate the width of the parcel, a "height" to indicate the height of the parcel, a "collection date and time" to indicate the date and time when the parcel can be collected, and a "delivery date and time" to indicate the date and time when the parcel can be delivered.

"Number" may be substituted with, for example, "weight" indicating the total weight of the luggage, or "volume" indicating the total volume of the luggage, or a partial combination of "quantity", "weight" and "volume", or "amount of luggage" indicating the amount of luggage. "Pickup date and time" and "delivery date and time" may each have a "start" indicating the start date and time of the period when pickup or delivery is possible, and an "end" indicating the end date and time of the period when pickup or delivery is possible.

The luggage information 111 may further include a "stowage position designation parameter" that indicates restrictions on the luggage stowage position. The "stowage position designation parameter" is, for example, a parameter corresponding to a loading method restriction such as no stacking, information on whether a certain luggage shape allows other luggage to be loaded on top of another luggage, or a placement restriction such as placing the luggage on the driver's side.

Figure 5 is a diagram showing an example of the data structure of vehicle information 112 in Example 1.

Vehicle information 112 includes at least a "vehicle name" that identifies the vehicle, a "loading limit" that indicates the maximum loading capacity of the vehicle, a "loading platform length" that indicates the length of the vehicle's loading platform, a "loading platform width" that indicates the width of the vehicle's loading platform, a "loading platform height" that indicates the height of the space on the vehicle's loading platform that can load cargo, a "vehicle unit price" that indicates the arrangement fee for one vehicle, a "operation unit price" that indicates the vehicle usage fee charged per vehicle operation hour, and an "unloading order specification parameter" that specifies the order in which cargo can be unloaded, which depends on the loading position.

The "loading capacity limit" may be substituted with, for example, a "loading weight limit" indicating the maximum loading weight of the vehicle, or a "loading volume limit" indicating the maximum loading volume of the vehicle, or a partial combination of the "loading capacity limit", "loading weight limit" and "loading volume limit", or a "loading volume limit" indicating the maximum amount of luggage that can be loaded into the vehicle. The "unloading order specification parameter" may also include information on the position of the door (i.e., the entrance/exit) of the loading platform of each vehicle used for loading and unloading luggage, information on the height from the loading platform to the ground, and information on other conditions related to the vehicle equipment. The vehicle information 112 may further include a "driver unit price" indicating the driver's labor cost per vehicle operating hour.

Figure 6 is a diagram showing an example of the data structure of location information 113 according to Example 1.

The location information 113 includes at least a "location name" that identifies the location, and a "loading/unloading time" that indicates the time required to load or unload at each location. The "loading/unloading time" is a value that varies depending on the information on the equipment and the worker related to loading or unloading at each location, and may be set in advance as an estimated time required to load or unload one piece of luggage at each location. The "loading/unloading time" may also be a value calculated from the actual data of the past loading and unloading times at each location. The "loading/unloading time" may include a "loading time" that indicates the unit time for loading, and an "unloading time" that indicates the unit time for unloading. For example, in the example shown in FIG. 6, it is shown that it takes 0.5 seconds to load or unload one piece of luggage at location 1, and 1 second to load or unload one piece of luggage at location 2.

The location information 113 may further include "latitude" indicating the latitude of the location, and "longitude" indicating the longitude of the location.

The location information 113 may further include an "unloading load parameter" indicating the magnitude of the impact of unloading work at a location (e.g., on surrounding traffic, etc.). The magnitude of the impact of unloading work at a location is considered to be small, for example, in a warehouse with a low transportation frequency and a large number of berths, because even if the time required for unloading is long, there is little risk of interfering with other transportation. On the other hand, for example, at a location with a small number of berths (or no berths), unloading may be performed on the road, and there is a risk that unloading on the road will cause traffic congestion. For this reason, the impact of unloading work at the location is considered to be large. The "unloading load parameter" may be a value that is set in advance for each location name, or may be a value calculated based on the usage status of the berth at each location and the congestion status of the surrounding roads. In addition to the usage status of the berth at each location and the congestion status in the surrounding area, a predicted value of an index related to the unloading load at any time in the future may be calculated based on past berth usage data and information on delivery schedules to each location. This makes it possible to plan work according to actual usage and traffic conditions. Information regarding the usage status of berths and the surrounding congestion status may be acquired by the planning management terminal 300, such as work progress information and sensor information at each collection and delivery point. The transportation planning device 100 may acquire the information from the planning management terminal 300 at each collection and delivery point via a network.

Figure 7 is a diagram showing an example of the data structure of birth information 114 in Example 1.

The berth information 114 includes at least a "location name" that identifies the location, a "berth name" that identifies a berth at the location, and an "acceptance time" that indicates the time when the berth is available to accept a vehicle. The "acceptance time" may include a "start" that indicates the start time of the period when acceptance is available, and an "end" that indicates the end time of the period when acceptance is available. The berth information 114 may also include information regarding the usage status of the berth and the traffic congestion status of surrounding roads. The information regarding the usage status of the berth may be, for example, information regarding whether the berth is currently in use or not, and information regarding the schedule when the berth is reserved for use.

Figure 8 is a diagram showing an example of the data structure of travel cost information 115 for Example 1.

The travel cost information 115 includes at least a "start point" that identifies the starting point of the travel, a "destination point" that identifies the destination of the travel, and a "travel time" that indicates the travel time from the start point to the destination. The travel cost information 115 may further include a "travel distance" that indicates the travel distance from the start point to the destination.

Figure 9 is a diagram showing an example of the data structure of evaluation information 116 related to Example 1.

The evaluation information 116 includes at least a "movement efficiency parameter" that indicates the degree of influence of operation efficiency on transport efficiency, and an "unloading efficiency parameter" that indicates the degree of influence of unloading efficiency on transport efficiency. The evaluation information 116 may be a preset value, or may be a value that is automatically calculated based on a simulation based on past performance data.

Here, the "travel efficiency parameter" and the "unloading efficiency parameter" may be values set for each candidate transportation plan. Specifically, the "travel efficiency parameter" and the "unloading efficiency parameter" may be calculated or determined based on the number of destination points in each candidate transportation plan, the travel distance between each point, or the unloading load parameter indicating the load related to unloading at each point included in the point information 113. It becomes possible to evaluate the influence of each of the travel efficiency and unloading efficiency on the overall efficiency of the transportation system for each transportation plan, which can contribute to the overall efficiency of the transportation system. Below, an example of determining the "travel efficiency parameter" and the "unloading efficiency parameter" is described.

When the distance between destinations included in the transportation plan is long, the fluctuation in travel distance when the destination is changed also becomes large, and therefore the impact of vehicle travel efficiency on the overall efficiency of the transportation system becomes large. For example, an example of such a transportation mode is trunk line transportation in which cargo is transported via specific large base warehouses. Therefore, as an example, the transportation planning device 100 may control the "travel efficiency parameter" to be larger as the index related to the distance between destinations included in the transportation plan becomes larger. The index related to the distance between destinations may be, for example, the average or median of the distance between destinations. Also, as an example, the transportation planning device 100 may control the "travel efficiency parameter" to be set to a value larger than the "unloading efficiency parameter" when the distance between destinations included in the transportation plan is larger than a predetermined threshold value.

On the other hand, when the locations and conditions for loading and unloading are limited, the impact of unloading efficiency on the overall efficiency of the transportation system becomes large. One example of such a transportation mode is intra-regional delivery, such as delivering goods from a warehouse to stores in a specific region. As such, as an example, the transportation planning device 100 may control the "unloading efficiency parameter" to be larger the larger the index related to the unloading load parameter of each point of the destination included in the transportation plan. The index related to the unloading load parameter may be, for example, the average value or median value of the unloading load parameter of each point. Also, as an example, the transportation planning device 100 may control the "unloading efficiency parameter" to be set to a value larger than the "movement efficiency parameter" when the index related to the unloading load parameter of each point of the destination is larger than a predetermined threshold value.

As another example, the transportation planning device 100 may determine the degree of influence that each of the travel efficiency and the unloading efficiency has on the overall efficiency of the transportation system based on an index related to the distance between destinations included in the transportation plan and an index related to the unloading load parameters of each of the destinations, and may determine the "unloading efficiency parameter" and the "travel efficiency parameter" based on the determination result. For example, if it is determined that the degree of influence of the travel efficiency is greater than the degree of influence of the unloading efficiency, the "travel efficiency parameter" may be controlled so that it is greater than the "unloading efficiency parameter". This allows for planning that takes into account the degree of influence that each of the travel efficiency and the unloading efficiency has on the overall efficiency of the transportation system.

In addition, the evaluation information 116 may be set to different values depending on the delivery method, such as the above-mentioned trunk line transportation, and on the work time period. For example, it is considered that the road congestion situation and the location and conditions of unloading change depending on the work time period. Therefore, when determining the "travel efficiency parameter" and the "unloading efficiency parameter", in addition to the above-mentioned information, the "travel efficiency parameter" and the "unloading efficiency parameter" for a specified time period may be determined based on information on the unloading load for each specified time period and traffic information for the specified time period.

In the example shown, the evaluation information 116 is used as two parameters, a "movement efficiency parameter" and an "unloading efficiency parameter", but it may be a single parameter that indicates the ratio between the "movement efficiency parameter" and the "unloading efficiency parameter".

In step S200 of FIG. 3, the transportation plan creation unit 121 uses the baggage information 111, vehicle information 112, location information 113, and movement cost information 115 to generate multiple transportation plan proposals for transportation using only available transportation resources and facilities, and stores the transportation plan proposals in the transportation plan proposal information 117. The transportation plan creation unit 121 may use the berth information 114 to generate a transportation plan proposal that also includes a plan for the berth where loading and unloading will be performed. The transportation plan proposal is generated, for example, by exhaustive search or simulation.

Figure 10 is a diagram showing an example of the data structure of the proposed transportation plan information 117 for Example 1.

The transportation plan information 117 has at least a plurality of transportation plan proposals. Each transportation plan proposal has at least a "vehicle name" that identifies the vehicle, a "location name" that identifies the location of the destination, a "berth name" that identifies the berth where the work will be performed, a "status" that indicates the work to be performed at the location, an "order number" that indicates the order to be worked on, a "number" that indicates the quantity of luggage, and a "time" that indicates the time when the work will be performed. The "number" may be substituted with, for example, "weight" that indicates the total weight of the luggage, or "volume" that indicates the total volume of the luggage, or a partial combination of "number", "weight" and "volume", or "amount of luggage" that indicates the amount of luggage. In addition, the "time" may have a "start" that indicates the start date and time of the time period when the work will be performed, and an "end" that indicates the end date and time of the time period when the work will be performed.

Returning to FIG. 3, in step S300, the stowage plan creation unit 122 uses the baggage information 111, the vehicle information 112, and the proposed transportation plan generated in step S200 to generate multiple stowage plans for each vehicle for which the baggage to be loaded in the proposed transportation plan has been determined, taking into account the baggage shape, and stores the stowage plan for all vehicles generated by combining the stowage plans for each vehicle in the proposed stowage plan information 118. If a loading position specification parameter is set for the baggage, only a stowage plan that satisfies the constraint is generated. For example, if parameter A, which indicates that stacking is not possible for the baggage of order number 2, is set, a stowage plan that does not stack the baggage of order number 2 is generated. The stowage plan is generated, for example, by exhaustive search or simulation.

Figure 11 is a diagram showing an example of the data structure of the proposed loading plan information 118 for Example 1.

The stowage plan information 118 includes multiple stowage plan proposals. Each stowage plan proposal has at least an "order number" that identifies the order to be stowed, a "loading order" that indicates the order in which the luggage in the order will be loaded, a "number" that indicates the quantity of luggage, a "length" that indicates the length of the luggage, a "width" that indicates the width of the luggage, a "height" that indicates the height of the luggage, and a "loading position" that indicates the position where the luggage will be loaded. The "number" may be substituted with, for example, "weight" that indicates the total weight of the luggage, or "volume" that indicates the total volume of the luggage, or a partial combination of "number", "weight" and "volume", or "amount of luggage" that indicates the amount of luggage.

Note that while Figure 11 shows only a loading plan proposal for one vehicle (vehicle A) as an example, the actual loading plan proposal information 118 includes loading plan proposals generated for each vehicle.

Returning to FIG. 3, in step S400, the plan evaluation unit 123 performs plan evaluation processing using the vehicle information 112, the location information 113, the evaluation information 116, one of the proposed transportation plans generated in step S200, and one of the proposed loading plans generated in step S300.

Figure 12 is a flowchart showing an example of a plan evaluation process performed by the plan evaluation unit 123 according to the first embodiment.

When processing begins, the plan evaluation unit 123 reads from the memory unit 110 the vehicle information 112, the location information 113, the evaluation information 116, one of the proposed transport plans stored in the proposed transport plan information 117, and one of the proposed stowage plans stored in the proposed stowage plan information 118 (S610).

In step S620, the plan evaluation unit 123 determines whether all of the cargo assigned to each vehicle in the proposed transportation plan read in step S610 has been loaded in the proposed loading plan read in step S610.

Only when it is determined in step S620 that all of the transport plans have been assigned, does the plan evaluation unit 123 perform steps S630 to S660 for all of the proposed transport plans.

In step S630, the plan evaluation unit 123 evaluates the travel efficiency using the vehicle information 112, the location information 113, and the proposed transportation plan. The travel efficiency is calculated, for example, as shown in the following formula (1). In formula (1), the smaller the travel efficiency value, the better the efficiency of travel. A predetermined evaluation value may be calculated based on the travel efficiency value. For example, the inverse of the travel efficiency value may be used, and the larger the evaluation value, the better the efficiency of travel.

Here, the relationship between travel time and vehicle operating time is expressed by the following equation (2).

In step S640, the plan evaluation unit 123 evaluates the unloading efficiency using the vehicle information 112, the location information 113, the proposed transportation plan, and the proposed stowage plan. The unloading efficiency is calculated, for example, as shown in the following formula (3). In formula (3), the smaller the unloading efficiency value, the better the unloading efficiency. A predetermined evaluation value may be calculated based on the unloading efficiency value. For example, the inverse of the unloading efficiency value may be used, and the larger the evaluation value, the better the efficiency of unloading.

The unloading time for each vehicle at each location can be calculated, for example, using the following formula (4).

Here, the cargo to be unloaded once refers to cargo that needs to be unloaded in order to remove the cargo to be delivered. The cargo to be unloaded once is specified based on the cargo loading position in the proposed loading plan and the unloading order specified by the unloading order specification parameter. The unloading time or loading time of each cargo may use the loading/unloading time information included in the location information 113. The unloading time or loading time of each cargo may also be calculated based on the information on the shape and weight of the cargo included in the cargo information 111, the information on the unloading order specification parameter including the position information of the cargo bed doors (i.e., entrances and exits) of each vehicle used for loading and unloading the cargo included in the vehicle information 112, and the information on the loading position of each cargo included in the proposed loading plan information 118.

In step S650, the plan evaluation unit 123 uses the evaluation information 116, the movement efficiency calculated in step S630, and the unloading efficiency calculated in step S640 to evaluate the overall efficiency of the transportation system using a weighted sum of the movement efficiency and the unloading efficiency as shown in the following formula (5). Then, in step S660, the plan evaluation unit 123 saves the combination of the proposed transportation plan and the proposed stowage plan as a provisional solution only if it is determined that the efficiency is good.

Note that the above calculation method is an example, and other calculation methods based on information stored in the memory unit 110 may be used. For example, the travel efficiency may be calculated based on the cost required for travel in addition to (or instead of) the travel time. The cost required for travel may be calculated based on cost-related information such as the vehicle unit price, operation unit price, and driver unit price included in the vehicle information. In that case, to explain using the example of formula (1), for example, the travel efficiency is calculated to be smaller as the cost is smaller. In other words, the smaller the cost, the better the efficiency regarding travel.

The unloading efficiency may also be calculated based on the impact of the unloading operation on the surroundings of each point in addition to (or instead of) the time required for unloading. The impact of the unloading operation on the surroundings of each point is given, for example, by the unloading load parameter in the point information. In that case, to explain using the example of equation (3), for example, the unloading efficiency may be calculated to be smaller the smaller the impact on the surroundings. In other words, the smaller the impact on the surroundings, the better the efficiency of unloading.

In the above example, the weighted sum of the movement efficiency and the unloading efficiency is calculated as an index showing the efficiency of the combination of the proposed transportation plan and the proposed stowage plan, and the index is evaluated to output the combination that is determined to have the highest overall efficiency of the transportation system. As an example, in accordance with the above-mentioned formula (1) and formula (3), the combination that has the smallest weighted sum of the movement efficiency and the unloading efficiency is determined to have the best overall efficiency of the transportation system. However, such a calculation method and output method are only an example, and other calculation methods and output methods may be used. For example, the movement efficiency and unloading efficiency of all combinations of the proposed transportation plan and the proposed stowage plan, or a plurality of combinations whose calculated efficiency is higher than a predetermined standard, may be output, and the user may select one of them. Alternatively, the combination of the proposed transportation plan and the proposed stowage plan in which the movement efficiency and the unloading efficiency are Pareto optimal may be output.

Returning to FIG. 3, the explanation will be given. Finally, in step S500, the provisional solution is output to the display unit 140. In addition, the communication unit 150 transmits the transportation schedule to the in-vehicle terminal 200 and the planning management terminal 300 at each collection and delivery point via the network N.

In this embodiment, the stowage plan draft creation unit 122 creates a stowage plan draft in accordance with stowage pattern information. Except for the differences described below, each part of the system in embodiment 2 has the same function as each part in embodiment 1 shown in Figures 1 to 16 with the same reference numerals, and therefore the description of those parts is omitted.

In addition to the information stored in the memory unit 110 of the first embodiment, the memory unit 110 of the second embodiment stores stowage pattern information 161, which is information about the combination patterns of vehicles and cargo that can be stowed, and cargoes themselves.

Figure 17 is a diagram showing an example of the data structure of stowage pattern information 161 for Example 2.

The stowage pattern information 161 has at least a "pattern code" that identifies the loading pattern, and a "baggage name" that identifies each baggage to be stowed. Each "baggage name" has a "type" that indicates the type of baggage, and a "loading position" that indicates the location of the baggage. The "loading position" may have a "row" that indicates the loading position counted from the front to the rear of the vehicle, a "column" that indicates the loading position counted from the right side to the left side of the vehicle, and a "tier" that indicates the loading position counted from the bottom to the top of the vehicle. The "loading position" may also be expressed in coordinates.

Return to the explanation of the changes from Example 1 to Example 2.

The luggage information 111 includes "type" indicating the type of luggage (not shown) in addition to the information included in the luggage information 111 of the first embodiment (see FIG. 4). Here, "type" may be information indicating a classification based on the size or weight of the luggage.

In addition to the information contained in the vehicle information 112 in the first embodiment (see FIG. 5), the vehicle information 112 also contains "loading patterns" (not shown) that indicate all possible loading patterns for the vehicle and are associated with the "type" information of the cargo. Here, the "loading pattern" may be a loading pattern that has been proven in the past.

In step S100, the memory unit 110 reads stowage pattern information 161 from the input device 460 in addition to the information read in step S100 in Example 1.

In step S300, the stowage plan creation unit 122 generates a stowage plan for all vehicles using the cargo information 111, vehicle information 112, stowage pattern information 161, and the transportation plan generated in step S200, and stores the stowage plan in the stowage plan information 118. The stowage plan for all vehicles is generated by searching for a stowage pattern for each vehicle for which cargo to be loaded has been determined in the transportation plan, adopting a stowage pattern that allows all cargo to be loaded as the stowage plan, and combining the stowage plan for each vehicle.

As an example, we will explain the search for a loading pattern when it is decided in the proposed transportation plan that 5 pieces of luggage of type L, 10 pieces of luggage of type M, and 10 pieces of luggage of type S will be loaded onto vehicle A. In this case, among the loading patterns that vehicle A can take, a loading pattern that allows 5 or more pieces of luggage of type L, 10 or more pieces of luggage of type M, and 10 or more pieces of luggage of type S to be loaded is searched for.

In the invention described in Example 2, a stowage plan can be created by using information indicating the type of cargo and pre-prepared stowage patterns without using detailed information on the size of the cargo, etc., which makes it easier to manage cargo data and create stowage plans, allowing for more efficient stowage plans to be created. In addition, a stowage plan is created according to stowage pattern information that is pre-prepared based on cargo type information, and a completely new stowage pattern is not created each time, so a highly reliable stowage plan can be created even without detailed information on the size of the cargo, etc.

A transportation planning system according to an embodiment of the present invention has been described above. Such a transportation planning system allows efficient transportation in terms of movement efficiency and unloading efficiency by taking into account the shape of the cargo.

The system of the present invention may also be configured as follows:

(1) A transportation planning system having a control unit (e.g., control unit 120) and a storage unit (e.g., storage unit 110) connected to the control unit, in which the storage unit holds luggage information (e.g., luggage information 111) including at least the shape, destination, and transportation volume of luggage based on an order, vehicle information (e.g., vehicle information 112) including information regarding the load capacity of one or more vehicles used to transport the luggage, and location information (e.g., location information 113) indicating multiple locations to which the luggage is to be transported, and the control unit generates multiple transportation plan proposals (e.g., For example, step S200), for each proposed transportation plan, multiple proposed stowage plans are generated based on the cargo information and vehicle information, including the stowage positions on each vehicle for each cargo to be transported according to the proposed transportation plan (for example, step S300), for each proposed transportation plan, a movement efficiency is calculated, which is an index showing the efficiency with which vehicles move between multiple locations according to the proposed transportation plan (for example, step S630), and for each combination of the proposed transportation plan and the proposed stowage plan, an unloading efficiency is calculated, which is an index showing the efficiency of at least the unloading work at multiple locations (for example, step S640), and the efficiency of the combination of the proposed transportation plan and the proposed stowage plan is calculated based on the movement efficiency and the unloading efficiency (for example, step S650).

This allows for efficient transportation in terms of movement and unloading efficiency, taking into account the loading position restrictions imposed by the shape of the cargo.

(2) In the transportation planning system described in (1) above, the memory unit further holds berth information (e.g., berth information 114) indicating available berths at each location, and the control unit generates multiple transportation plan proposals based on the baggage information, vehicle information, location information, and berth information.

This allows for the generation of transportation plans suited to the actual conditions at each location.

(3) In the transportation planning system described in (1) above, the vehicle information includes information indicating the position of the cargo bed door of each vehicle (e.g., parameters specifying the unloading order), and the control unit generates a proposed loading plan so that cargo assigned to each vehicle based on the proposed transportation plan is brought in from the position of the cargo bed door of each vehicle and loaded sequentially into positions where loading is possible.

This allows for the generation of a viable loading plan.

(4) In the transportation planning system described in (1) above, the memory unit further holds stowage pattern information (e.g., stowage pattern information 161) that associates cargo types with stowage positions, and the control unit generates a stowage plan proposal based on the stowage pattern information.

This makes it easier to generate a proposed loading plan, and if there are loading patterns that have proven successful in the past, they can be used to generate a new proposed loading plan.

(5) In the transportation planning system described in (1) above, the memory unit further stores weighting coefficients (e.g., evaluation information 116) to be assigned to the movement efficiency and unloading efficiency, and the control unit calculates the efficiency of the combination of the proposed transportation plan and the proposed stowage plan based on a weighted sum of the movement efficiency and unloading efficiency based on the weighting coefficients.

This allows the efficiency of the combination of the proposed transportation plan and the proposed loading plan to be appropriately evaluated based on movement efficiency and unloading efficiency.

(6) In the transportation planning system described in (5) above, the location information includes load information indicating the magnitude of the impact that unloading work at each location has on the surrounding area of each location, and the weighting coefficient is determined based at least on the load information.

This allows the efficiency of the combination of the proposed transportation plan and the proposed loading plan to be properly evaluated.

(7) In the transportation planning system described in (5) above, the weighting coefficient is determined based on at least the travel distance between a plurality of points.

This allows the efficiency of the combination of the proposed transportation plan and the proposed loading plan to be properly evaluated.

(8) In the transportation planning system described in (1) above, the vehicle information includes information indicating the cost of each vehicle and driver (e.g., vehicle unit price, operating unit price, driver unit price, etc.), and the control unit calculates the travel efficiency based on the cost of each vehicle and driver corresponding to travel between multiple points.

This allows movement efficiency to be calculated appropriately.

(9) In the transportation planning system described in (1) above, the control unit calculates information on the time required for unloading at each location based on the baggage information and vehicle information, and calculates the unloading efficiency based on the time required for unloading (e.g., formula (3)).

This allows for proper calculation of unloading efficiency.

(10) In the transportation planning system described in (9) above, the vehicle information includes information indicating the position of the doors of the cargo bed of each vehicle (e.g., parameters specifying the unloading order), and the time required for unloading at each point includes the time required to unload cargo whose destination is each point, and the time required to unload and reload cargo that is temporarily unloaded in order to unload the cargo, calculated based on the relationship between the position of the cargo and the position of the door (e.g., formula (4)).

This allows for proper calculation of unloading efficiency.

(11) In the transportation planning system described in (10) above, the location information includes load information (e.g., unloading load parameters) that indicates the magnitude of the impact that unloading work at each location has on the surrounding area of each location, and the control unit calculates the unloading efficiency based on the baggage information, vehicle information, and load information.

This allows for proper calculation of unloading efficiency.

(12) The transportation planning system described in (1) above further includes a display unit (e.g., display unit 140) connected to the control unit, and the display unit displays the combination of the proposed transportation plan and the proposed stowage plan that is determined to have the highest calculated efficiency.

This allows the user to be presented with the most efficient combination of transportation and loading plans.

(13) The transportation planning system described in (1) above further includes a display unit (e.g., display unit 140) connected to the control unit, and the display unit displays multiple combinations of the proposed transportation plan and the proposed stowage plan, and the movement efficiency and unloading efficiency corresponding to each combination.

This allows the user to select from several possible combinations of proposed transportation plans and proposed loading plans.

(14) The transportation planning system described in (1) above further includes a vehicle terminal (e.g., vehicle terminal 200) mounted on each vehicle and communicating with a control unit via a network (e.g., network N), and a location management terminal (e.g., planning management terminal 300 at each collection/delivery point) installed at each point and communicating with the control unit via a network, and the vehicle terminal mounted on each vehicle outputs information about each vehicle (e.g., display screen 800) from among the information included in the transportation plan, and the location management terminal installed at each point outputs information about each point (e.g., display screen 900) from among the information included in the transportation plan.

This allows the necessary information to be provided to drivers of each vehicle and workers at each location.
