Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a chartering system that allocates charter flights for a vehicle allocation plan composed of a plurality of operation routes, and relates to a system that optimizes the daily charter flight allocation and obtains optimum charter contents in a calculation target period.
[0002]
[Prior art]
At the time of daily dispatch, it is unclear how many charter flights will run in the month, so the basic charge cannot be distributed by the number of times or distance until the end of the month. Therefore, an appropriate judgment has not been made as to which route charter flights should be dispatched. If it is verified whether the cost can be reduced by actually using charter flights, the number of empty charter flights (not operating) increases, which may increase the cost.

[Problems to be solved by the invention]
The present invention has been made to eliminate the above-described drawbacks of the prior art, and its purpose is to optimize daily charter flight allocation, as well as vehicle allocation plans (planned) and past vehicle allocation results. Based on this, it brings the most reduction effect Vehicle type / loading capacity By calculating the number of units, the optimal charter flight contract will be implemented to reduce transportation and delivery costs.
[0005]
In addition, it is possible to judge the increase or decrease of the cost compared with the current estimate response of the charter contract, and it is also possible to contract with a carrier having a charge system that is most suitable for own transportation and delivery.
[0006]

Department.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
Hereinafter, the present invention will be described based on embodiments shown in the drawings. FIG. 1 is a diagram showing an entire system relating to inventory and distribution. In the figure, the variable order point management system is a system for deriving optimal order points from inventory information, plan information, demand forecasts, and order plans. Thereby, the required amount for each route is obtained.
The distribution cost optimization schedule generation system is a system that realizes a transportation schedule for a predetermined period at a minimum cost based on a request amount for each route. As a result, an optimal vehicle allocation plan is established.
The present invention relates to a chartering system that makes optimal use of charter based on this dispatching plan and past dispatching results.
By utilizing these systems organically, it can be expected to significantly reduce the cost of inventory and distribution.
[0008]
First, this system has two functions: charter flight allocation calculation and charter flight contract calculation. Charter flight dispatch calculation is aimed at optimal dispatch every day with charter contracts established, and charter flight contract calculation is aimed at finding the optimal charter contract contents for the charter contract period. It is said.
Hereinafter, a simple image of the calculation will be described.
[0009]
FIG. 2 is a diagram showing an image of charter delivery dispatch calculation. Charter flight allocation calculation can determine the operating route for dispatching charter flights and the truck type (vehicle type / loading capacity) of the charter flights to be dispatched there.
The spot cost for the operating route and the cost to be added outside the basic charge of the charter contract are calculated. Based on the difference between the spot cost and the cost outside the charter contract basic charge, the amount of reduction during charter delivery can be determined. This reduction is calculated for all routes for one day.
Then, optimization can be achieved by allocating the number of charter flight contracts (three in this example) to the route with a large reduction amount.
[0010]
FIG. 3 is a diagram showing an image of charter flight contract calculation. In this process, in order to implement a charter contract with the greatest cost reduction effect, a combination of the number of units for each truck type (vehicle type / loading amount) is obtained.
Assuming the calculation target period, the vehicle allocation plan or actual vehicle allocation during that period is used. In addition, assuming a plurality of combinations of the number of vehicles for each vehicle type / loading amount, the aforementioned reduction amount within the calculation target period is calculated for each, and the reduction amount for the calculation target period is obtained by subtracting the charter basic charge. The optimization can be achieved by adopting the charter contents based on the combination of the number of each truck type (vehicle type / loading amount) in which the amount of reduction in the calculation target period is maximized.
[0011]
The operation and configuration of this system will be described below. FIG. 4 shows an overall flowchart.
Subsequent to initial processing (S401) such as setting of processing parameters, cost calculation for carrying by a spot (S402) and cost calculation for carrying by a charter (S403) are performed.
[0012]
In the cost calculation at the spot (S402), the cost is calculated based on the spot fee table. Calculate tolls for actual toll roads and ferries. In addition, the distance schedule and the time schedule are set according to the contract with the supplier, such as setting for each route or using the one that is cheaper in cost calculation.
[0013]
In the cost calculation in the charter (S403), the cost is calculated based on the chart of the charter. Charter contracts (vehicle type / loading amount) are calculated regardless of the transport / delivery load amount (carrying amount).
[0014]
When the processing parameter is 1: Charter flight dispatch calculation (S404), the dispatch calculation (S405) is performed. This makes it possible to obtain the charter adoption operation route and the reduction amount (excluding the charter basic monthly amount) that maximizes the reduction amount based on the specified charter content (number of contracted truck types).
[0015]
On the other hand, when the processing parameter is 2: Charter flight contract calculation (S404), the contract calculation (S406) is performed. As a result, it is possible to obtain the charter assumption contents and the reduction amount (including the charter basic monthly amount) with the maximum reduction amount in the dispatching plan (the actual number of dispatches) from the plurality of specified charter assumption contents (number of truck types). it can.
[0016]
Finally, the result is output (S407). In the case of charter allocation, the charter flight adoption result WORK 3105 charter adoption operation route, vehicle type, loading capacity, and reduction amount (excluding the basic charter monthly fee) are output. On the other hand, in the case of charter contract calculation, “Characteristic period reduction” of the charter content assumption combination WORK1100 outputs the combination of the number of units and the amount of load for each vehicle type / loading amount (including the charter basic monthly charge) To do.
[0017]
Hereinafter, each process is explained in full detail.
FIG. 5 is a diagram showing an initial processing flow. First, processing parameters (1: charter flight allocation calculation, 2: charter flight contract calculation) are set (S501). In addition, a calculation target period (past vehicle allocation record or future vehicle allocation schedule) is set. Set the start date of the calculation target period to the specified date. In the case of charter flight contract calculation, specify the beginning and end of the month as the calculation target period. Also, calculate the number of months in the period. In addition, the vehicle type, loading capacity (in ascending order), and the number of vehicles by vehicle type and loading capacity are acquired. In the case of charter delivery dispatch calculation, it is stored in the charter content WORK. In the case of charter flight contract calculation, the individual maximum number is also acquired. FIG. 6 is a diagram illustrating an example of the charter content WORK.
[0018]
Thereafter, the route setting information is saved (S502, S503), and the fee-based fee setting information is also saved (S504, S505). Then, the dispatch plan within the calculation target period is saved in the work WORK 1303 (S506 to S508). You can also use the actual vehicle allocation instead of the vehicle allocation plan.
[0019]
In the case of charter flight contract calculation, a charter content assumed combination is set (S510). For vehicle types / loading volumes not specified by truck type (vehicle type / loading amount), all combinations are created for the truck type (vehicle type / loading amount) within the range of individual maximum number. The assumed charter content combination will be described later with reference to FIG.
[0020]
Here, examples of the above-described route setting master and pay usage fee setting master are shown. FIG. 7 is a diagram illustrating an example of a route setting master. For the spot fee setting, one of km: distance system (for traffic jam routes), time: time system (for traffic routes without traffic jam), and money: distance system and time system with lower cost is set. As a restriction, vehicles exceeding 4t cannot be used. If the distance is short, the placement is NG. If the crane equipment column is “None”, there is no equipment such as a crane at the delivery / delivery site, so a vehicle with a UNIC or crane may be required depending on the delivery / delivery item.
FIG. 8 is a diagram illustrating an example of a pay usage fee setting master. This makes it possible to calculate a pay usage fee.
[0021]
An example of a vehicle allocation plan is shown. FIG. 9 is a diagram illustrating an example of a vehicle allocation plan. Each line corresponds to a service route. As shown in the figure, depending on the delivery / delivery item, the vehicle type may be limited to aluminum van, unic, lorry, etc. In addition, a plurality of operation routes may be set for the same route. FIG. 10 is a diagram illustrating an example of a vehicle allocation plan including the route. For example, it may occur due to the following circumstances.
1. The transport volume is greater than the maximum load capacity.
2. Vehicle types are limited by conditions such as road width and site area.
3. Vehicles are divided into flat bodies and lorries for transport and delivery items.
However, even when multiple flights are dispatched on one route in this way, in this system, processing is considered as another operation route.
[0022]
Furthermore, an example of the charter content assumption combination WORK1100 is shown. FIG. 11 is a diagram illustrating an example of the charter content assumption combination WORK 1100. This example is generated based on the charter content WORK of FIG.
For example, combinations 0 to 5 are created for A, B, and C in the figure. However, D is not eligible because there is no vehicle type / loading capacity.
[0023]
Next, the spot cost calculation will be described in detail. Thereby, the cost when a spot contract vehicle is allocated for the vehicle allocation plan is calculated. FIG. 12 is a diagram showing a cost calculation flow at a spot. FIG. 13 is a diagram illustrating a configuration related to cost calculation at a spot. The spot cost calculation unit 1302 calculates the cost at the spot for each operation route of the dispatch plan of the work WORK 1303 and stores it in the spot cost calculation result WORK 1304.
[0024]
FIG. 14 is a diagram showing an example of a one-way fare distance-based fare table. FIG. 15 is a diagram illustrating an example of a distance-based fare table for round-trip fares. FIG. 16 is a diagram showing a hourly fee table. FIG. 17 is a diagram showing an addition fee table. FIG. 18 is a diagram illustrating an example of WORK related to cost calculation at a spot.
[0025]
Processing will be described with reference to FIG.
First, the spot cost calculation unit 1302 acquires the spot contract fee table for the corresponding vehicle type from the spot contract fee master 1301 (S1201). Then, the fare is obtained from the spot fee setting and the loading amount (S1202). If the spot fee setting is distance-based, one-way and round-trip are distinguished. In the case of a time system, the number of hours is determined. If neither is specified, the distance and time systems are calculated and the one with the lowest cost is selected. In this example, any setting can be made by contract with the carrier.
When the detention permission is OK (perform detention), the spot cost calculation unit 1302 obtains a detention fee with the corresponding load amount (S1203).
The spot cost calculation unit 1302 calculates an amount corresponding to the loading amount if the vehicle type is UNIC when the fee for the UNIC vehicle is set to go out with an additional fee to the flat body fee (S1204). If the UNIC vehicle is not a uniform addition, it can be handled by setting the UNIC or crane-equipped vehicle as a separate vehicle model and setting the UNIC fee to 0, which is included in the distance and time-based fares.
Next, the travel distance and scheduled operation time of the vehicle allocation plan are checked against the replacement driver addition condition in the spot contract fee table, and a replacement driver fee is obtained if necessary (S1205). In this example, any setting can be made by contracting with a carrier such as early morning and late night treatment.
Further, the unloading fee is calculated based on the number of unloading plans and the unloading fee addition amount (S1206).
Charges for actual toll roads and ferries are also calculated (S1207). The charge of the pay usage No set in the route is counted by judging one-way and round-trip. Also, if a round-trip discount occurs on a ferry, etc., it is calculated by determining whether the round-trip is being used. Finally, the above charges are totaled (S1208).
These charges are recorded in the item of the spot cost calculation result WORK 1304, and are finished when all the operation routes are processed (S1209).
[0026]
Next, charter cost calculation will be described in detail. With this process, the additional cost excluding the basic monthly amount when a charter contract vehicle is allocated for the allocation plan is calculated. Also, it is not determined whether or not loading is possible, and the cost when charter flights run for each truck type (a combination of vehicle type and loading fee) is calculated.
[0027]
FIG. 19 is a diagram illustrating a cost calculation flow in the charter. FIG. 20 is a diagram illustrating a configuration relating to cost calculation in a charter. The charter cost calculation unit 2002 calculates the charter cost for each truck type for each operation route of the dispatch plan of the work WORK 1303 and stores it in the charter cost calculation result WORK 2004.
[0028]
Here, the charter contract will be described. FIG. 21 is a diagram showing an example of charter contract basic fee conditions. FIG. 22 is a diagram showing a charter contract number / basic charge / additional charge table.
When the travel distance exceeds 100 km, the fuel cost for the excess km is calculated from the fuel consumption. If the operating time exceeds 8 hours, the overtime fee for the excess time is calculated from the labor cost / h. No detention fee will be charged due to an all day charter contract. However, if it is not a charter for weekends and holidays, a detention fee will be set for loading on the weekends and holidays. The unloading fee is paid without a unic and crane, but 0 is set when the unic and crane are not paid. In this example, the charter type blank represents a flat body and is treated as a substitute with a hood, aluminum van, unic, etc. On the other hand, it is not possible to substitute an aluminum van or unic with a flat body. This is because items that cannot be wet are equipped with aluminum vans and hoods, and when unic is required for loading and unloading, unic is set as a transport and delivery item, so the type of vehicle is limited. When using charter flights for different types of oil and chemicals for trailers, etc., use is set, and when using for general purposes, use is not set. Similarly, if a flat car or an aluminum van is used as a dedicated vehicle, the application is set.
[0029]
An example of WORK related to cost calculation in a charter will be shown. FIG. 23 is a diagram illustrating an example of WORK related to cost calculation in a charter. FIG. 24 is a diagram showing the overtime portion. FIG. 25 is a diagram showing a detention fee portion. FIG. 26 is a diagram showing a substitute member portion. FIG. 27 is a diagram illustrating the unloading fee portion. FIG. 28 is a diagram showing a toll portion. FIG. 29 is a diagram showing the additional amount outside the charter basic fee.
[0030]
Processing will be described with reference to FIG.
The charter cost calculation unit 2002 first obtains a chart of the charter contract of the corresponding vehicle type from the charter contract charge master 2001 (S1901). Then, the additional fuel cost is obtained from the charter fee setting (distance and fuel unit price of basic fee condition, fuel consumption by truck type (vehicle type / loading amount) of the additional fee) and the charter calculation distance (S1902).
Subsequently, an additional overtime fee is obtained from the charter fee setting (the basic fee condition time and the labor cost for each additional truck type (vehicle type / loading amount)) and the charter trial operation time (S1903).
If the detention permission for the operation route is OK (perform detention), it is obtained from the detention fee for each truck type (vehicle type / loading amount) corresponding to the additional fee (S1904).
Compare the mileage and scheduled operation time of the dispatch plan with the replacement driver addition conditions in the charter contract basic charge conditions, and add replacement driver charges for each applicable truck type (vehicle type / loading amount) if necessary. (S1905). In this example, any setting can be made by contracting with a carrier such as early morning and late night treatment.
The unloading fee is calculated based on the number of unloading plans in the vehicle allocation plan, the basic charge conditions of the charter contract, and the additional amount of unloading charges for each applicable truck type (vehicle type / loading amount) (S1906).
Charges for actual toll roads and ferries are also calculated (S1907). Charges for pay usage No set for the route are always round-tripped. Also, if a round-trip discount occurs on a ferry, etc., it is calculated by determining whether the round-trip is being used. Finally, the above charges are totaled (S1908).
The process ends when each route is processed for each track type. S1909).
[0031]
Next, the vehicle allocation calculation process will be described. FIG. 30 is a diagram showing a vehicle allocation calculation flow. FIG. 31 is a diagram illustrating a configuration related to vehicle allocation calculation.
The vehicle allocation calculation unit 3101 includes a charter assumed reduction amount calculation unit 3102, a charter flight adoption operation selection unit 3104, and a charter flight empty vehicle allocation unit 3106. Is configured to use.
[0032]
First, the charter expected reduction amount calculation unit 3102 calculates the expected reduction amount in the charter (S3001). The difference between the spot cost and the non-charter contract basic charge is calculated as the estimated reduction amount. Calculate the expected reduction for charter contracts that can be loaded and have a valid truck type. Details will be described later with reference to FIG.
Next, the following processing is repeated for each day in the calculation target period.
First, charter flight adoption operation selection unit 3104 performs charter flight adoption operation selection (S3002). Decide the charter flight route and charter truck type (vehicle type / loading capacity). In addition, the estimated reduction amount of the operation route that uses charter flights is calculated. Details will be described later with reference to FIG.
Next, as a result of processing by the charter flight adoption operation selection unit 3104, if charter flights are empty (S3003), charter flight empty allocation (S3004) is performed. An empty charter flight occurs when a truck type with a small load capacity is not eligible for adoption because the load capacity of the charter flight is less than the transport volume. In such a case, it is also determined whether to load a part of the truck and further deliver the remaining delivery by a spot contracted truck. At this time, a pattern that can most reduce the occurrence of spot costs is adopted. Details will be described later with reference to FIG. One day is added to the specified date (S3005), and the process is repeated until the specified date> the end date of the calculation target period (S3006).
[0033]
The above-described estimated reduction calculation (S3001) will be described in detail.
FIG. 32 is a diagram showing a flow for calculating the expected reduction amount in the charter. FIG. 33 is a diagram illustrating a configuration relating to calculation of an assumed reduction amount in a charter. FIG. 34 is a diagram showing an example of WORK related to calculation of an assumed reduction amount in a charter. FIG. 35 is a diagram showing an example of the charter content WORK600.
[0034]
For each route, repeat the following process for each track type.
First, it is determined whether a charter is assumed (S3201). Specifically, a charter is assumed when all of the following conditions are met.
(1) Vehicle restrictions = None OR Vehicle restrictions ≥ Charter contents WORK of charter flights on WORK
(2) Charter content Number of WORK charter flights by WORK NOT = 0
(3) Work WORK transport and delivery ≤ Charter contents WORK charter flights loading capacity (4) Spot cost calculation result WORK dispatch plan model = Charter contents WORK charter model
As for (4), in this example, the blank of the charter type is treated as a substitute for a flat body, a hood, an aluminum van, a unic or the like in a truck.
[0035]
Spot cost calculation result WORK 1304 spot cost-charter cost calculation result WORK2004 is calculated as an addition amount outside the charter basic charge, and is set to an expected reduction amount of charter flights of a charter expected reduction amount WORK3103 (S3202).
When all the truck types of charter flights have been processed, the process proceeds to the next operation route processing (S3203). When all charter cost calculation results WORK2004 have been processed, the process ends (S3204).
[0036]
The above-described charter flight adoption operation selection (S3002) will be described in detail. FIG. 36 is a diagram showing a charter flight adoption operation selection flow. FIG. 37 is a diagram illustrating a configuration relating to selection of an operation to employ charter flights. FIG. 38 is a diagram showing an example of WORK related to selection of employment operation of charter flights.
[0037]
In this process, if there are multiple selectable truck types (vehicle types / loading capacity) for one route, chartered cars with less than the transport volume will remain if priority is given to those with larger loading capacity. In order to efficiently use chartered vehicles, the truck type with a small loading capacity is given priority.
The selectable remaining operation route WORK 3701 is used in order to extract a selectable operation route in order from the truck type with the smallest load capacity. The number of charter flights empty 3702 is used to store the number of charter flights that become empty as a result of this processing.
[0038]
As the processing, the following processing is performed in order from the smaller load amount for the truck type in which the number of charter flights is one or more in the charter contents WORK600 (S3601).
As a process of extracting selectable remaining service route (S3602), the charter flight adoption result WORK3105 is adopted from the charter assumed reduction amount WORK3103 for the specified date for the chart type (vehicle type / loading amount) of one charter flight of the charter content WORK. A non-operating route (with an estimated reduction amount of blank) is extracted as a selectable remaining operating route WORK 3701.
Then, as charter flight adoption operation selection processing (S3603), the operation route having a larger estimated reduction amount than the selectable remaining operation route WORK 3701 is extracted to the charter flight adoption result WORK 3105 up to the number of charter flights of the charter content WORK.
When all chart types (vehicle type / loading amount) of the charter content WORK600 are processed, the loop process is terminated (S3604).
[0039]
Finally, as the charter flight number calculation process (S3605), the charter flight number of charter contents WORK600 by truck type (vehicle type / loading capacity) is subtracted by the number of charter flight adoption results WORK3105, the number of charter flights is obtained, and the number of charter flights is set to 3702 Remember.
[0040]
The charter flight empty allocation process (S3004) will be described in detail. FIG. 39 is a diagram showing an allocation flow of charter flights. FIG. 40 is a diagram showing a configuration relating to allocation of charter flights.
The charter flight empty vehicle allocation unit 3106 includes a charter flight empty assumed cost calculation unit 4001, a remaining spot loading and cost calculation unit 4003, a charter flight empty assumed reduction calculation unit 4005, and a charter flight empty operation selection unit 4007. The cost calculation result WORK 4002, the charter empty space remaining loading spot WORK 4004, and the assumed reduction amount WORK 4006 of adopting the charter flight empty vehicle are used.
[0041]
FIG. 41 is a diagram showing an example of a part of WORK related to allocation of charter flights. FIG. 42 is a diagram showing an example of the number of charter flights. FIG. 43 is a diagram illustrating an example of the charter empty space remaining loading spot WORK4004. FIG. 44 is a diagram showing an example of an assumed reduction amount WORK4006 for charter flights. FIG. 45 is a diagram showing an example of a charter flight empty vehicle adoption result WORK3107.
[0042]
As processing, first, charter flight vacancy adoption assumed cost calculation section 4001 performs charter flight vacancy adoption assumed cost calculation (S3901). As a result, the cost in the case where the charter flight empty vehicle is adopted as the charter non-adopted operation route is acquired from the charter cost calculation result WORK 2004 and stored in the charter flight empty vehicle cost calculation result WORK 4002. If the vehicle type restriction and the vehicle allocation plan are not met, it will not be possible to acquire the cost because it cannot be used for the charter flight route. All of the operation routes that have not been used for the charter are processed for all the truck types (vehicle types / loading amounts) where there is an empty charter flight (S3902).
[0043]
Next, the remaining loading spot loading and cost calculation unit 4003 performs the remaining loading spot loading calculation (S3903). Charter flight cost calculation result WORK 4002 charter flight empty vehicle adoption exceeds the maximum load capacity, so the vehicle type and load capacity of the spot required to load the remaining load capacity are calculated. The load amount of the work WORK 1303 minus the charter flight empty vehicle load amount becomes the remaining load amount. Further, the remaining loaded spot cost calculation unit 4003 calculates the remaining loaded spot cost (S3904). In this process, the cost of the remaining loading spot is calculated and stored in the charter flight empty remaining spot WORK4004. The same processing is performed by changing the WORK of the cost calculation at the spot.
Charter flight empty vehicle cost calculation result WORK 4002 All charter non-adopted operation routes of the charter flight empty vehicle type (vehicle type / loading amount) stored are processed (S3905).
[0044]
Next, the charter flight adoption assumed reduction amount calculation unit 4005 calculates the assumed reduction amount for charter flight use (S3906). The assumed reduction amount when the charter flight empty vehicle is adopted is calculated and stored in the assumed reduction amount WORK4006 adopted by the charter flight empty vehicle. The spot cost calculation result WORK 1304 is obtained by subtracting the charter flight empty vehicle cost calculation result WORK4002 addition amount outside the charter basic charge and the charter flight empty vehicle remaining loading spot WORK from the charter flight empty vehicle remaining loading spot.
The spot cost is stored in the charter flight empty spot loading spot WORK,
All charter flight routes that have not been chartered for the charter flight type and loading capacity are processed (S3907).
[0045]
Finally, the chartered flight adoption operation selection unit 4007 performs chartered flight adoption operation selection (S3908). The charter flight truck type (vehicle type / loading amount) and the remaining loading spot truck type of the selected operation route are selected by selecting the combination of charter contents (empty vehicle adoption operation) that maximizes the reduction amount in WORK4006 as the assumed reduction amount of charter flight empty vehicle adoption. (Vehicle type / loading amount) and the reduction amount are stored in the charter flight result WORK3107.
[0046]
Next, the contract calculation (S406) described above will be described. FIG. 46 is a diagram showing a contract calculation flow. FIG. 47 is a diagram showing a configuration relating to contract calculation. FIG. 48 is a diagram showing an example of WORK related to contract calculation.
The contract calculation unit 4701 includes a charter content selection unit 4702, a calculation target period setting unit 4703, a vehicle allocation calculation unit 4704, and a reduction amount calculation unit 4705.
[0047]
As processing, first, the charter content is selected by the charter content selection unit 4702 (S4601). 1 is added to the charter content No., and the charter content No. content is stored in the charter content WORK. The calculation target period setting unit 4703 sets the start date of the calculation target period to the designated date (S4602), and the vehicle allocation calculation unit 4704 performs vehicle allocation calculation (S4603). This process is the same as the process of the vehicle allocation calculation unit 3101 described above. Charter content assumption combination For each combination (charter content) of the number of charter flight truck types (vehicle type / loading amount) of WORK1100, charter allocation is sequentially performed during the calculation period to obtain a reduction amount. The calculation is made up to the end date of the calculation target period (S4604).
In the calculation of the reduction amount by the reduction amount calculation unit 4705 (S4605), the number of months of the calculation target period of the charter basic monthly amount is obtained and subtracted from the total expected reduction amount of the calculation target period to obtain the reduction amount of the calculation target period.
The process ends when all the charter contents have been processed (S4606).
[0048]
The chartering system is a computer, and each element can execute processing by a program. Further, the program can be stored in a storage medium so that the computer can read the program from the storage medium. Each WORK is an example of a storage unit.
[0049]
【The invention's effect】
In the present invention, daily charter flights can be optimized.
[0050]
In addition, by calculating the number of truck types (vehicle type / loading capacity) that has the most reduction effect based on the vehicle allocation plan (planned) and past vehicle allocation results, the contract for the optimal charter flight is executed, and the transportation and delivery costs Can be reduced.
[0051]
As a result, for example, it is possible to determine an increase or decrease in cost compared with the current estimate response of a charter contract, and it is also possible to contract with a carrier having a charge system that is most suitable for own transportation.
