BEST MODE FOR CARRYING OUT THE INVENTION The delivery date management system of the present invention calculates the completion delivery date of the highest-order product based on the answer of the delivery date of the material from each material maker in assembling the device having the multi-stage material configuration. , To answer. In addition, when the actual completion delivery date is later than the set completion delivery date of the product, it also has a function of outputting information indicating which material caused the delay. The outline will be described below with reference to FIG. FIG. 1 is a block diagram showing a configuration example of an embodiment of a delivery date management system according to the present invention.

In FIG. 1, MRP (Material Requirements Planning (M
aterial Requirement Planning)) The calculation process 21 fetches various information such as the product requirement information 15 and the material order information 16 including the response delivery date from the parts maker, performs the material requirement development and the material order quantity calculation, and performs the required information 31. And the order information 32 are generated.

[0010] Next, the allocation and delivery date calculation processing 22 allocates each order of the order information 32 to each requirement of the requirement information 31 from the item lower in the level of the parts table. At this time, if the delivery date of the allocated order is later than the required required date, the number of delay days is set.

Next, when the order delivery date of the higher-order item corresponding to the requirement is earlier than the delivery date calculated from the number of delay days,
The order delivery date of the higher order item is reset by the delivery date calculated from the number of delay days. This procedure is sequentially performed up to the highest level, and the allocation result information 33 is created so that the delay in order delivery of the lower order item is transmitted to the product using the member.

Further, the delayed product search processing 23 extracts, out of the allocation result information 33, those which have been delayed and which have been registered as product requirements, and output them as delayed product information 34. The delay cause order search processing 24
Searches for the correspondence of the specified one delayed product from the allocation result information 33, extracts the materials involved in the completion of the product, and further specifies the delayed material in the delay cause order information. Output as 35.

Next, an embodiment of a delivery date management system according to the present invention will be described in detail with reference to FIG. As shown in FIG.
5. Based on the material order information 16 and the like, material development and material order quantity calculation are performed, and the necessary information 31 and the order information 32 are calculated.
Calculation processing 21 for generating the
For the required information 31 generated by, the allocation processing of the inventory quantity of the inventory quantity information 14 and the order of the order information 32, and
The allocation and delivery date calculation processing 22 that corrects the delivery date of the higher order based on the difference between the allocated required date and the number of days between the delivery date of the order, and the product whose delivery date is delayed based on the allocation result information 33 output by the allocation and delivery date calculation processing 22 , And a delayed product search process 23 for outputting the delayed product information 34 to the delayed product information 34, and a delay product order search process for searching the order that caused the product delay from the allocation result information 33 and outputting the delayed product order information 35. 24.

As information files, material information 11 storing information on the materials, configuration information 12 defining the parent-child relationship of the materials, calendar information 13 defining holidays used for schedule calculation, inventory information of each material, And inventory quantity information 14 having a number.

Next, the operation of this embodiment will be described in detail with reference to the flowcharts of FIGS.

The MRP calculation process 21 performs multi-level material requirement development and order quantity calculation from the material information 11, the configuration information 12, the calendar information 13, the stock quantity information 14, the product requirement information 15, and the material order information 16. , New required information 31 and order information 32 are generated. At that time, for a new order, a delivery date that secures the procurement lead time for the material information is set as a delivery date (that is, a delivery date is a date that has elapsed the number of days of the procurement lead time on the working day from the start date of calculation). . Note that the method of calculating the MRP is described in a production management textbook, and a description thereof will be omitted.

Next, in the allocation and delivery date calculation processing 22,
The allocation process and the due date calculation process are performed according to the procedure shown in the flowchart of FIG. In the following, the material composition (combination of the material information 11 and the configuration information 12) used in the description is shown in FIG. 3, the required information 31 is shown in FIG. 4, the order information 32 is shown in FIG. 5, and the stock quantity information 14 is shown in FIG. The following example shall be used. The calendar is closed on Saturday and Sunday and five days a week.

First, in step S1, material information 11, configuration information 12, calendar information 13, and stock quantity information 14 are read. Next, in step S2,
Steps S3 to S1 in order from the material at the lower level of the configuration level
Step 3 is repeated. Starting from the lower level material of the configuration level indicates that processing is performed from the lower side (lower level) of the material configuration shown in FIG.

In step S3, the necessary information of the corresponding material is read, and in this case, the materials are sorted in ascending order of the required date. Next, the process proceeds to step S4, where order information of the material is read. In step S5, loop control is performed so that the processing of steps S6 to S9 is repeated for each read order.

That is, in step S6, the required information 3
1 (FIG. 4) is searched to see if there is a requirement to have a "higher order number" (FIG. 4) equal to its own order number (FIG. 5). If there is a requirement having the “higher order number” equal to the order number of the user, the process proceeds to step S7, and the higher required delivery date change date is calculated based on the lower required requirement change date. If there is more than one requirement, it is calculated based on the largest date. The calculation method is as follows: delivery date change date = delivery date + (required change date−required date). On the other hand, if there is no need to have the “higher order number” equal to the own order number, the process proceeds to step S8, and the delivery date is set as the delivery date change date. When the processing in step S7 or step S8 ends, the process proceeds to step S9.

In step S9, it is determined whether or not there is an order for the corresponding material. If there is still an order for the corresponding material, the process returns to step S5, and the processes of steps S5 to S9 are repeatedly executed. On the other hand, if there is no order for the material, the process proceeds to step S10.

In step S10, the orders are sorted in order of the delivery date change date. Next, the process proceeds to step S11, where the requirements sorted in step S3 are compared with the stock,
Assign orders sequentially. Next, in step S12, the allocation result is output as allocation result information 33.

Next, the process proceeds to step S13, where it is determined whether or not there is a material. If there is still a material, the process returns to step S2, and the processes of steps S2 to S13 are repeatedly executed. On the other hand, if there is no material, the process ends.

Next, the above processing will be described in detail with reference to specific examples shown in FIGS. First, in step S1, material information 11, configuration information 12, calendar information 13, and stock quantity information 14 are read. Thereafter, the process proceeds to step S2, and the processing is performed in order from the material “SHIZAI-C” which is a lower level of the configuration level of the material configuration shown in FIG.

First, in step S3, the required information 31 of "SHIZAI-C" of the required information 31 shown in FIG.
Read the items. After that, when the required dates are used as keys to sort in ascending order, the required order is 1998/3/4 and the required order is 1998/3/6. Next, the process proceeds to step S4, where "SHI
One piece of order information of "ZAI-C" is read.

In step S5, when there are a plurality of orders, control is performed so that each order is processed in a loop. In step S6, it is determined whether there is a corresponding lower level requirement. In this case, since there is no corresponding lower order requirement, the process proceeds to step S8, and the delivery date change date is set to 1998/3/4 as it is.

Next, the process proceeds to step S9, where it is determined whether or not there is an order. In this case, "SHIZAI-
Since there is only one order for "C", the process proceeds to step S10. In step S10, sorting is performed in the order of the delivery date change date. Next, the process proceeds to step S11,
Inventory and orders are allocated to the two requirements (demands) sorted in 3. Next, in step S12, the allocation result is output as allocation result information 33.

The result of the allocation is the first two lines of the allocation result information (in order of required date) 33 in FIG. In other words, the required number of the first required (1998/3/4) is 80, but since the stock is 0 (see the stock quantity information in FIG. 6), the required number of “SHIZAI-C” in FIG. 80 out of the order number 150 of the order (order number FFF) is allocated. At this time, the required (1
On the required change date of 998/3/4), the order (order number FF)
The delivery date change date of F) (1998/3/4) is set.

Further, the difference between the required change date and the required date is set to delay. In this case, since the required change date and the required date are the same day, 0 is set. In other words, the difference between the required date of the "required requirement" and the delivery date change date of the "assigned order" is calculated on an operating day basis. Next, for the second requirement (1998/3/6), the order (order number FF)
F) 20 out of 150 orders are allocated, and the required change date and delay are similarly set. In this case, 1998/3/6 is set on the required change date, and -2 (= 199
8/3 / 4-1998 / 3/6) is set.

In this way, “SHIZAI-C” is allocated and output to the allocation result information 33.

In step S13, it is determined whether or not there is any material. In this case, since there is still material, the process returns to step S2, and the processes of steps S2 to S13 are repeatedly executed, and the process for "SHIZAI-B" is executed. "SHIZAI-B" is also processed in the same manner as in the case of "SHIZAI-C", and results are shown in the third to sixth lines of the allocation result information (in order of required date) 33 in FIG.

Next, "SHIZAI-A" is processed. First, in step S3, of the required information 31 shown in FIG. 4, three required items of "SHIZAI-A" are read. After that, when the required date is used as a key to sort in ascending order, the required order is 1998/3/9, 1998/3/11, and 1998/3/13. Next, in step S4, three orders of "SHIZAI-A" in the order information 32 shown in FIG. 5 (order numbers AAA, B
BB, CCC).

Next, proceeding to step S5, a loop control is performed so that the processing of steps S6 to S8 is executed for each order.

That is, in step S6, it is determined whether there is a corresponding lower level requirement. In this case, since the order (order number BBB) and the order (order number CCC) have corresponding lower-level requirements, the process proceeds to step S7, and the delivery date change date is changed from the lower-level required change date as follows. Is calculated.

According to FIG. 7, the order (order number BBB) has a required date and a required change date of 19 for the corresponding lower two requirements.
Since it is 98/3/4, from the calculation formula, the delivery date change date = 1998/3/11 + (1998/3/4
−1998/3/4) = 1998/3/11.

The order (order number CCC) has two corresponding lower required change dates of 1998/3/6 and 199
Since it is 8/3/9, take the larger one and use the formula to calculate the date of change of delivery date = 1998/3/13 + (1998/3/9
−1998/3/6) = 1998/3/16.

Since the order (order number AAA) does not require a lower order, the delivery date is set as it is in step S8. That is, in the case of this example, the manufacturing process of “SHIZAI-A” corresponding to the order (order number AAA) has already been started, and “SHIZ” used for the manufacturing has been started.
Since “AI-B” and “SHIZAI-C” have already been paid out to the site, there is no need for lower ranks.

Next, in step S9, it is determined whether or not there are any more orders, that is, whether or not the processing for all the orders has been completed. When the process for all the orders is completed, the process proceeds to step S10. Step S
At 10, sorting is performed in the order of the delivery date change date. As a result, the order of the order is the order of the order numbers AAA, BBB, and CCC.

Next, in step S11, stocks and orders are allocated to the requirements sorted in step S3. The allocation result is the 7th to 11th lines of the allocation result information (in order of required date) 33 in FIG. In other words, the required number of the first requirement (March 3, 1998) is 40, but the inventory is 20, so 20 of the inventory is allocated to the first requirement. When inventory is allocated, required change date =
It is a required date, and delay = “−”. Next, since the required number 20 (40-20) has not been allocated yet, the order (AA)
20 out of 30 orders in A) are allocated. On the required change date, the date of change of the delivery date of the order (AAA)
And the delay is 1 (1998/3 / 10-199)
8/3/9) is set.

Subsequent requirements are processed in the same manner to obtain allocation result information (in order of required date) 33 in FIG. In FIG. 7, the required (1998/3/13) delay of the 11th line is 1, as described above, as described above on March 3, 1998, 199.
This is because 8/3/15 is a holiday.

Next, the process proceeds to step S13, where it is determined whether or not there is any material to be processed. In this case, since there is no more material to be processed, the process ends.

Next, the processing of the delayed product search processing 23 will be described in detail. In this processing, of the results of the allocation result information (in order of required date) 33 in FIG. 7, the result is a requirement registered as a product requirement (a requirement in which a valid value is set in the product requirement NO), and delay> 0 Are retrieved and retrieved. As a result, as shown in FIG.
Is output as

Next, the processing of the delay cause order search processing 24 will be described in detail. In this processing, the material causing the delay is extracted for the specified product requirement. The result is output as delay cause order information 35 as shown in FIG.

First, allocation result information (in order of required date) 3 in FIG.
The affected range is extracted from the correspondence of each row of No. 3. Less than,
An example will be described. Here, it is assumed that the requirement of product requirement NO = 3 is specified. For this requirement,
From line 11 in FIG. 7, inventory and orders (order number CCC) are allocated. From FIG. 7, order (order number CCC)
Is required for “SHIZAI-B” (date required = 1998 /
3/6) and "SHIZAI-C" requirements (date required = 19)
98/3/6). "SHIZAI-B"
(Required date = 1998/3/6), the order (order number DDD) and order (order number EEE)
In addition, required for “SHIZAI-C” (required date = 1998)
// 3/6), an order (order number FFF) is allocated. Therefore, as shown in FIG. 9, the order (order number CCC, DD
D, EEE, and FFF).

As described above, for each product requirement, it is possible to quickly and accurately calculate when the completion delivery date will be reached in the current material ordering situation. As a result, it is possible to quickly and accurately reply to an inquiry about the completion delivery date of a new order requested from a sales department or the like.

Further, when a delivery date is changed from a material maker for a product for which an order has been received, the influence on the completion delivery date of each product can be quickly known. Further, when the influence becomes a problem, it becomes possible to determine a material that is a factor. From the result, it is also possible to determine whether or not to request the material maker to advance the delivery date.

Next, another embodiment of the present invention will be described. Embodiment described above (Embodiment A)
In the above, the order of allocation to the product requirements is the order of the required date. However, in other embodiments (embodiment B), the allocation is performed in the priority order taking into account the importance of each requirement. The result is shown in FIG.
Shown in In the embodiment A, out of the requirements for “SHIZAI-A”, the required (1998/3/9) and the required (1998)
/ 3/13), there was a delay in the two cases, but in the embodiment B, the delay occurred only in the required (3/9/1998), and the delay was 5, and in the case of the embodiment A It is getting bigger.

As described above, by using the embodiment B, it is possible to make assignments beyond the earliest required date, and this is effective when there is a product requirement that one does not want to delay.
