[0002]

2. Description of the Related Art Various systems for preparing a transportation plan for a cargo or a container with the support of a computer have been considered. Japanese Patent Application Laid-Open No. 62-1070 proposes a system for drafting a transport plan while interacting with a user. Japanese Patent Application Laid-Open No. 6-259411 discloses a plurality of processes for drafting a transport plan for a transport target in each transport medium. An agent model type system in which modules are provided and a transportation diagram is created through information exchange between the modules is disclosed.

[0003] In the recent logistics industry, freight transport using pallets that enables more efficient cargo handling operations is increasing.
The pallets are transported to various parts of the country with their luggage loaded, where they are unloaded and then shipped with new luggage to another area. However, freight transportation is one-way transportation from the supply area to the demand area, and the amount of transportation between the areas is not balanced. A situation occurs in which there are not enough pallets for loading. for that reason,
It will be necessary to constantly manage pallet stock and re-route empty pallets from over-existing areas to over-existing areas.

[0004] The forwarding of the empty pallet is not sufficient if the shortage of the pallet is performed after it is revealed. It is necessary to predict the amount of cargo transported at each logistics base and forward the required number of pallets in advance so as not to hinder the cargo transport. In addition, the route for this forwarding must be selected so as to reduce the transportation costs.

Literatures discussing the forwarding of containers and pallets include "Construction of a simulation system for predicting the number of required pallets (Kazuhiro Kojima, etc.)" and "Consideration on the problem of planning pallet forwarding (Masaki Kato et al .: Information Processing Society of Japan, 50th National Convention) ”or“ Container forwarding plan by mathematical programming ”(Fukumura: RTRI REPORT Vol. 8, No. 2, '
94.2) ", and in the last document,
A method for obtaining a container forwarding plan based on mathematical programming is explained using a model.

The operation of each means of this device will be described. The user activates the high-speed planning means 11 when it is necessary to quickly determine the pallet forwarding plan. High-speed planning means 11
Makes a pallet forwarding plan at high speed according to the flowchart of FIG.

Step 1100: The high-speed planning means 11 outputs the UI 20
Step 1110: The data stored in the initial data storage device 31, the actual data storage device 32, and the planning result storage device 33 are read into the storage area 19. At this time, from the initial data storage device 31, for example, FIG.
Read the freight cost data between each logistics base shown in
From the planning result storage device 33, data on the actual surplus or shortage of pallets (hereinafter referred to as excess or deficiency) with respect to the standard stock quantity data for the planned number of days at each distribution base as shown in FIG. The data of the excess / deficiency number is created by the pallet number prediction means 13).

Step 1120: The high-speed planning means 11 classifies each base into a demand place and a supply place based on the data, and creates a demand arrangement and a supply arrangement, respectively.

Step 1130: The supply destinations are sorted in ascending order of transportation cost from the j-th demand location to each supply location. In this case, the demand places are Aomori, Morioka and Yamagata, and the supply place is Sendai.

Step 1140: From supply point k to demand point j,
The pallet forwarding service is generated until the demand amount of the demand place becomes 0 or the supply amount of the supply place becomes 0.

Step 1150: It is determined whether or not the demand of the demand area has become 0. If it is 0, Step 1155: It is determined whether or not the demand of all the demand areas is 0. Returning to 1130, the processing from step 1140 is performed for the next demand place j + 1.

Step 1160: In step 1150, if the demand at the demand location is not 0, it is determined whether or not the supply amounts of all the supply locations are 0, and if not, the process returns to step 1140. The pallet forwarding service from the next supply location k + 1 to the demand location j is generated. Supply amount of all supply points is 0
If so, step 1170: determine whether the target period is over or not, step 1180: if it is over, end all processing. If not, the process returns to step 1120 to move to the next day.

If it is determined in step 1155 that the demand amounts of all the demand areas are 0, the process on the i-th day is terminated, and the process proceeds to step 1170.

The pallet forwarding service determined by the high-speed planning means 11 is stored in the planning result storage device 33 and presented to the user through the UI 20.

As described above, the high-speed planning means 11 determines the forwarding destination and the forwarding destination of the pallets in ascending order of the freight rates, based on the freight rates between the physical distribution bases. Since the determination is based on simple rules, processing can be performed at high speed.

When the user needs a comprehensive pallet transfer plan between a number of distribution bases, the user activates the transfer service determining means 12. The forwarding service determining means 12 determines the number of forwarding flights of the pallets and the number of forwarding pallets according to the flowchart of FIG.

Step 1200: The forwarding service determining means 12 executes the UI
When activated by 20, Step 1210: Read data stored in the initial data storage device 31, the actual data storage device 32 and the planning result storage device 33 into the storage area 19. At this time, as the data, for example, the standard stock quantity data of each distribution base and the data of the excess and deficiency number of pallets shown in FIG. 15 and the data of the transportation cost between each distribution base shown in FIG. 16 are input.

Step 1215: Since an n-day plan is made, a plan for the first day is first made. The linear plan shown in FIG. 18 is obtained by using the contents of the supply and demand table shown in FIG. 17 (showing the transportation costs between the supply place Si and the demand place Di) in the first day of each distribution base using the contents of the supply and demand table shown in FIG. Convert to a format that can be input to the means.

FIG. 18 shows a formula of the product sum of the number of pallets X _ij carried from each supply location i to the demand location j and the transportation cost from the supply location i to the demand location j, and is carried out from each supply location i. Formulating that the sum of the pallets is equal to or less than the excess number of pallets on the first day of the supply location i and the sum of pallets carried to each demand location j is greater than or equal to the shortage of pallets on the first day of the demand location j ing.

Step 1220: The necessary data on the first day is input to the linear programming means, and the product sum of the number of pallets and the transportation cost is calculated so as to take the minimum value. The result shown in 19 is output.

Step 1235: This is converted into the data of the number of flights between the distribution bases shown in FIG. 20, and the data obtained by converting the first day into a calendar date is added. Step 1240: The obtained result is obtained. The data is stored in the storage area 19. Next, Step 1250: It is determined whether or not the target period is over. Step 1260: If it is over, the data of the storage area 19 is output to the storage device 33 for storing the planning result, and the processing is ended. If the target period has not ended, the process returns to step 1220, and the number of flights on the next day is obtained.

When calculating the number of forwarded flights on the next day, the planning result of the previous day is reflected in the supply and demand of pallets.

As described above, the forwarding service determining means 12 drafts a detailed pallet forwarding plan using the linear programming method, determines the number of forwarding flights, the number of forwarding pallets, etc., and presents them to the user.

The user activates the pallet number predicting means 13 in order to know the predicted number of pallets existing at the distribution base. The pallet number predicting means 13 predicts the number of pallets present at each distribution base according to the flowchart of FIG.

Step 1300: The pallet number predicting means 13
When activated by the UI 20, step 1310: From the data stored in the initial data storage device 31, the actual data storage device 32, and the planning result storage device 33, for example, to the distribution base (in this case, Asahikawa) shown in FIG. It reads in and out the transport schedule and the number of pallets transported by this transport, and also reads the number of pallets transported to each logistics base, the delivery schedule interval, and the standard stock number under the transport plan.

Step 1320: When the simulated date “November 29” and the logistics base name “Asahikawa” are input from the UI 20, step 1330: The pallet number prediction means 13 specifies the designated data from the read data. Calculate the time series data of the number of pallets on the designated day of the distribution base, analyze this, find a function approximating the variation of the number of pallets per day, and store the obtained result in the planning result storage device 33, The information is displayed as shown in FIG. 5 through the UI 20. Step 1340: End.

As described above, the pallet number predicting means 13 presents the daily fluctuation of the number of pallets at the designated distribution base in comparison with the reference stock number. When the number of pallets is above the reference stock number, the pallets are in an excess state, and when they are below the pallet numbers, they are in an insufficient state.

At the stage where the user has grasped the actual number of pallets (actual value) at each distribution base, if the number differs from the predicted value (planned number) of the required pallets, the actual feedback means 14 To make a pallet forwarding plan to fill this gap. At this time, the performance feedback means 14 operates according to the flowchart shown in FIG. 6, and determines a forwarding plan.

Step 1400: Performance feedback means 14

Step 1510A: From the data stored in the initial data storage device 31, the actual data storage device 32, and the planning result storage device 33, for example, as shown in FIG. The data, the data on the number of excess and deficiency of the pallets for three days, and the transportation costs between the bases shown in FIG.
Further, two days at a schedule interval designated by the user are stored in the storage area 19 as parameters.

Step 1520A: Set the initial value i = 0 and calculate a schedule counter. Step 1522A: Set the counter value to the specified schedule interval 2
It is determined whether or not it is the day, and if they do not match, step 1521A: The excess / deficiency data on the first day is added to the excess / deficiency data on the second day.

Step 1520A: The schedule counter is incremented by one. Step 1522A: Since the schedule counter matches on the second day, Step 1524A: The excess or deficiency number on the second day can be input to the linear programming means shown in FIG. Step 1525A: Input to linear programming means.

Step 1530A: FIG.
A value of 6 is output.

Step 1533A: This is converted into data on the number of flights between each distribution base, and data obtained by converting the first day into a date on the calendar is added. Step 1540A: The result is stored in the storage area 19 Then, step 1550A: determine whether the target period is over, and if not, return to step 1520A. If it is the end, the data in the storage area 19 is output to the planning result storage device 33, and step 1560A: end.

After the end, the planning result is displayed on the UI 20. If the user is not satisfied, the parameters of the schedule interval are changed, and the schedule interval determination support means 15A is activated again.

In order to set the schedule interval of the pallet forwarding to the optimum value, the user sets the schedule interval automatic determination means 15B.
Start The schedule interval automatic determination means 15B operates according to the flowchart of FIG. 8, and determines the schedule interval of pallet forwarding.

Step 1500B: Automatic schedule interval determination means 15
