DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manufacturing industry, in particular, an order-made manufacturing system for manufacturing products requiring a long time to supply intermediate materials and parts. The present invention relates to a load allocation method for performing allocation, a load allocation system, and a delivery date determination method, a delivery date determination system, a production method, a production system, and a recording medium for calculating and outputting a delivery date of a newly ordered property.

[0002]

2. Description of the Related Art A conventional production management system is a system for creating a production schedule after receiving an order. Therefore, taking into account the condition of the production line at the time of receiving the order, the past delivery date, the production lead time (time required for production) agreed by both the production and sales departments, etc. The delivery date of the order was determined.

[0003] For this reason, coordination between people at a meeting or the like is required from the time an order is received until the delivery date is determined, and the delivery date cannot be determined in a short time. In addition, since a production plan is performed for each production line, when a plurality of items are included in one order (order), it is difficult to make adjustments between the production lines in order to shorten the delivery time of each item. Products that have been completed early must be kept in stock until all the products in the order have been completed, causing a problem that the inventory of finished products increases. Further, in order to change the production plan, it is necessary to cancel all the previous production plans and to re-plan a new one, which requires a great deal of labor and time. Also,
These decisions required experience and were not easy for everyone to make. As described above, the conventional production management system has a number of problems.

[0004] Thus, a system devised is a capacity quota system, also known as a production seat system. This system is an application of a transportation seat reservation system to a production management system, and the production line takes over the amount of products that can be produced on a specific production line every certain period, for example, every day. The total amount or a part of the production line capacity load that can be set is set in advance (usually the total amount), and this is set as a capacity frame. Then, an order is assigned to the capacity frame. For example, when the daily operation time of a certain production line is set as the capacity frame, the operation time of the production line required to produce all the items of the product pertaining to the order is obtained, and the vacant portion of the capacity frame is obtained. Assigned to. Then, the last day of the days corresponding to the assigned capacity frame is the delivery date of the product. With this capacity frame system, an accurate delivery date can be known in a short time, and it can be quickly answered whether or not the customer can meet the desired delivery date, and if not, when the delivery date will be. Also,
Even when one order contains a plurality of items, it is easy to assign the orders to capacity slots so that the delivery dates of the respective items are close, and the inventory of finished products can be reduced. It became so.

[0005]

However, the capacity framing system is based on the premise that materials and parts are always supplied sufficiently. That is, the load is assigned in consideration of only the capacity of the production line, and the delivery date is determined.

However, as in the case of producing photographic light-sensitive materials, for example, the materials and parts to be used take a long time to be supplied, and stable supply of materials is not always desired. In the case where the material is not a material that can be obtained, even if the delivery date is determined by the production management system using only the capacity frame, there arises a problem that the supply of the material is delayed and the delivery time cannot be met. Also, when producing a product that takes a long time to become a product from raw materials, it takes a very long time to produce from raw materials after receiving an order. In order to shorten the lead time from shipment to shipment, intermediate materials are sometimes produced in anticipation. Even in such a case, the intermediate material cannot be produced in a large amount in excess, so that the supply of the intermediate material cannot always be performed sufficiently stably.
Due to a delay in the supply of materials, problems such as being unable to meet a delivery date arise. Also, under such a system with many uncertain factors, the expected delivery date cannot be an accurate delivery date, while it is difficult to obtain an accurate delivery date taking into account the uncertain factors. It takes time.

Further, in order to prevent such a delay in delivery, it is necessary to always supply the material stably, so that a stock of the material is required.

The present inventor has found that the above problem can be solved by considering not only the capacity of the production line required for production but also the material as a "frame".

Therefore, the present invention does not always require a stable supply of materials, such as products that require a long time to supply materials and parts and products that anticipate the production of intermediate materials. Even when producing products for which it is difficult to obtain materials, accurate delivery times can be easily obtained in a short time after receiving an order, and it is possible to reduce inventory of finished products and materials. It is an object of the present invention to provide a production management system that performs

The capacity frame 30 indicates the type of the production line and the operation time that can be operated at regular intervals, and in other words, indicates the capacity load that can be assigned at regular intervals. In the present embodiment, the certain period is set to one day. For example, August 21
As the capacity frame 31 of the day (Fri), it is set that the line A can be operated for 3 hours and the line B can be operated for 4 hours. Therefore, on August 21 (Fri), the capacity load for the three-hour operation of line A and the capacity load of line B for four hours
The capacity load for the time operation can be allocated.

On the basis of the calendar stored in the calendar storage unit 6, the type and the operation time of the production line that can be operated every day, that is, the capacity load that can be allocated every day, in other words, the capacity frame for each day, are displayed on the CRT display. By inputting from the keyboard 7 while looking at the screen 8, the ability frame 30
Set. Then, the capacity frame 30 is stored in the capacity frame storage unit 3.

Next, the setting of the material frame will be described. FIG. 4 is an explanatory view of the material frame. The material frame 40 indicates the type and amount of the material that can be supplied at regular intervals,
In other words, it indicates the material load that can be assigned at regular intervals. In the present embodiment, the certain period is set to one day. For example, as the material frame 41 on August 21 (Fri), it is set that four original volumes A can be supplied and three original volumes B can be supplied. Therefore, the original volume A on August 21 (Fri)
, And the material load for the three original windings B can be allocated.

On the basis of the calendar stored in the calendar storage section 6, the type and amount of material that can be supplied on a daily basis, that is, the material load that can be allocated on a daily basis, in other words, the material frame for each day, can be viewed on the CRT display 8. While inputting from the keyboard 7, the material frame 40 is set. Then, the material frame 40 is stored in the material frame storage unit 1.

In the present embodiment, the setting of the capacity frame and the material frame can be performed within a range of three months from the day.
It is controlled so that setting after three months from the day cannot be performed. Of course, the period of three months can be changed, and it is possible to set the capacity frame and the material frame regardless of the time without setting the period.

Either the setting of the capacity frame or the setting of the material frame may be performed first.

In this embodiment, the unit of the original volume is a book, but may be m ² .

In the capacity frame or the material frame, not all of the total load that can be allocated but only a predetermined ratio of the total amount of the load that can be allocated may be displayed as the capacity frame or the material frame. (Hereinafter, this ratio is referred to as the "disclosure rate."
And For example, if the disclosure rate of the capacity frame is set to 90%, and the total capacity load of the line A that can be actually allocated on August 21 is 3 hours 20 minutes, that is 90%. The time is set as a capacity frame and displayed on the CRT display 8. When an urgent order with the desired delivery date of August 21 is entered, the line A is already
Although the capacity load is allocated for 3 hours, even if it is apparently impossible to allocate a further capacity load for the line A, actually the capacity load for the line A for one third of the time can still be allocated. Yes, we can respond to urgent orders. By setting the disclosure rate in this way, it becomes easier to respond to urgent orders.

Next, the setting of the material load and the capacity load for each product will be described.

FIG. 6 shows the material load and capacity load for each of the film A and the film B. As shown in FIG.
Must be operated for 0.05 hours, and
0.03 are required. On the other hand, film B
It is necessary to operate the line B for 0.03 hours to manufacture the individual pieces, and 0.01 of the original winding B is required as a material.
In other words, the capacity load for one film A is line A0.05 hours, and the material load is the original volume A0.0.
It is three. On the other hand, the capacity load for one film B is 0.03 hours for the line B, and the material load is the original volume B0.
It is for 01.

The delivery date determination system 11 has a material load storage unit 2 and a capacity load storage unit 4, and stores the material load of each product and the capacity load of each product. By inputting data from the keyboard 7 in advance for each product, the material load storage unit 2 stores, for each product type, the type and amount of material necessary to manufacture one product (the material per product). Load) is stored in the capacity load storage unit 4.
For each type of product, the type of production line and the operating time required to manufacture one product (capacity load per product)
Is stored. Then, each time a new product is released, a new material load and a capacity load corresponding to the new product are set, so that a new product can be handled.

Next, how the load is assigned to the capacity frame and the material frame and the delivery date is determined by the system after receiving the order will be described with reference to the flowchart shown in FIG.

Step 1 (S1): An order is received with the capacity frame 30, the material frame 40, and the capacity load and material load for each product set in advance. As shown in FIG. 5, the order needs to have at least the type and quantity of the product related to the order as information. Further, it is preferable that the customer also have the desired delivery date as information.
For example, the desired delivery date of order I is August 25, and the products related to order I have 100 pieces of film A and 200 pieces of film B. And the order I50
(Product item, quantity, desired delivery date) is input from the keyboard 7. The input order I50 is stored in the order storage unit 1.
2 is stored.

If there is no desired delivery date, it is not necessary to input the desired delivery date.

In order to make it easier to manage information on each order, each order has an ID number and the like.
Information such as D information, the name of the person who entered the order, and the date entered may be added to the order.

Step 2 (S 2): The information of the order 50 I stored in the order storage unit 12, the material load of each product stored in the material load storage unit 2 and the capacity load storage unit 4, and Based on the information on the capacity load of one of the various products, the arithmetic unit 10 determines the type and amount of the materials necessary for manufacturing all the products related to the order I50, and the type and operation time of the production line, that is, the order I. The material load and the capacity load are calculated and obtained.

FIG. 7 shows the material load and the capacity load according to the order I50 obtained in the arithmetic unit 10 by the method described above. As shown in FIG. 7, the material load according to the order I50 is as follows: three primary rolls A and two primary rolls B, and the capacity load is 5 hours for line A and 6 hours for line B. .

The capacity load and material load related to the order thus obtained may be displayed on the CRT display 8 or output by the printer 9.

Step 3 (S3): After calculating the capacity load and the material load related to the order I50, the calculation unit 10 allocates the capacity load related to the order I50 to the capacity frame.

The delivery date determination system 11 has an assigned load storage unit 5 and, before assigning the capacity load and the material load related to the order I50, has already assigned to the set capacity frame and material frame. The assigned capacity load and material load are stored in the assigned load storage unit 5.

FIG. 8 shows a capacity frame and allocated capacity loads (hereinafter, referred to as “load-allocated capacity frames”). Then, the load-allocated capacity frame 80A is displayed on the CRT display 8. Further, it may be output from the printer 9.

On August 21, it is preset as a capacity frame that the line A can be operated for 3 hours and the line B can be operated for 4 hours. Among them, the capacity load for operating the line A for 2 hours is set. And the capacity load for operating the line B for two hours have already been allocated, and are stored in the allocated load storage unit 5 as allocated capacity loads. Therefore, the capacity loads that can be assigned to the capacity frame for August 21 are the capacity load for line A for one hour and the capacity load for line B for two hours.

If it is no longer possible to assign a capacity load to the capacity frame for each day, the mark 100
Is displayed as shown in FIG. Therefore, August 2
On the 2nd and 23rd, no more capacity load can be allocated.

Then, the capacity load related to the order I50 is set to a capacity frame to which the capacity load can be assigned.
It is automatically assigned by the arithmetic unit 10 in consideration of the desired delivery date.

FIG. 10 is a diagram showing a result of allocating the capacity load according to the order I50 to the capacity frame 80A to which the load has been allocated. In the present embodiment, as a result of allocating the capacity load related to the order I50, the capacity frame 80B to which the load has been allocated is displayed on the CRT display 8.

The specific procedure of the capacity load allocation related to the order I50 is as follows: from August 25, which is the desired delivery date, to August 24 and 23, so that the product related to the order is completed exactly at the desired delivery date. Retrospectively, the capacity load is sequentially assigned to a capacity frame having a space to which the capacity load can be assigned. In the present embodiment, the order I50
Is 5 hours for line A and 6 hours for line B. Therefore, in line A, the capacity load of 3 hours on August 25 and 2 hours on August 24 are allocated, and in line B, the capacity load is allocated on August 25.
By assigning a capacity load of 3 hours on the time, August 24, the capacity load is assigned to the capacity frame in accordance with the desired delivery date of August 25.

The assignment of the capacity load may be automatically performed by the arithmetic unit 10 as in the present embodiment, or the operator of the delivery date determination system may display the capacity frame to which the load has been assigned on the CRT display 8 or the like. Keyboard 7 while watching
May be input.

Step 4 (S4): Next, as a result of allocating the capacity load to the capacity frame, it is determined whether or not the allocation can be performed in time for the desired delivery date.

The capacity load is allocated to the capacity frame retroactively from the desired delivery date, and when all the capacity loads related to the order can be allocated, the allocated result is set as the desired delivery date and the allocated load storage. This is stored in the section 5 and then the material load according to the order of step 5 is allocated to the material frame.

In the present embodiment, the desired delivery date is 8
Since the capacity load can be allocated to the capacity frame retroactively from the month 25 and all the capacity loads related to the orders can be allocated, the scheduled delivery date is August 25.

On the other hand, retroactively from the desired delivery date, the capacity load is allocated to the capacity frame, and when all the capacity loads related to the order cannot be allocated, that is, the capacity load is allocated in time for the desired delivery date. If you fail to do so, you will be asked to add 8
On the 26th and 27th of the month, the capacity load that could not be allocated is sequentially allocated to the capacity frame having a space where the capacity load can be allocated, and after the total capacity load related to the order is allocated, the capacity load is allocated. The last day of the assignment is set as the scheduled delivery date, and then the assignment of the material load related to the order in step 5 to the material frame is performed. Then, the assigned result is stored in the assigned load storage unit 5. For example, if the desired delivery date is 25 days but the last day to which the capacity load is assigned is 27 days, the scheduled delivery date is 27 days.

Incidentally, it is also possible to allocate the capacity load to the capacity frame from the earliest day on which the capacity load can be allocated, without allocating the capacity load to the capacity frame, going back from the desired delivery date. This is preferable when there is no information on the desired delivery date of the order.

Step 5 (S5): After allocating the capacity load related to the order I50 to the capacity frame, the calculation unit 10 allocates the material load related to the order I50 to the material frame.

FIG. 9 shows an assigned material load (hereinafter, referred to as a “load assigned material frame”) before assigning the material frame and the order I50. Then, the load-assigned material frame 90A is displayed on the CRT display 8. Further, it may be output from the printer 9.

For example, on August 21, it is preset as a material frame that four original volumes A can be supplied and three original volumes B can be supplied. The material load to be used and the material load to use one original winding B are:
It is already assigned and stored in the assigned load storage unit 5 as the assigned material load. Therefore, the material loads that can be allocated to the material frame for August 21 from now on are the original winding A, three windings, the original winding B, and two windings.

If the material load can no longer be assigned to the daily material frame, the mark 100
Is displayed. Therefore, on August 22 and 23,
The material load related to the main winding A cannot be allocated any more. Further, on August 21, 22, and 23, the material load relating to the original volume B cannot be allocated any more.

The material load related to the order I50 is set to a material frame to which the material load can be assigned.
The calculation unit 10 automatically assigns the scheduled delivery date and the result of the assignment of the capacity load to the capacity frame.

FIG. 11 shows the result of assigning the material load according to the order I50 to the material frame. In the present embodiment, as a result of allocating the material load related to the order I50, the load-allocated material
It is displayed on the display 8.

The specific procedure of material load assignment will be described below. First, from the capacity frame to which the capacity load related to the order is allocated, the item and quantity of the product related to the capacity load allocated to the capacity frame per day in step 5 are obtained every day, and the same item and the same quantity of the product are obtained. Is assigned to the material frame on the same day as the capacity load. Then, the assignment of the material load is performed retroactively from the scheduled delivery date obtained in step 5 based on the result of the assignment of the capacity load.

Specifically, in the present embodiment, step 5
, The capacity load related to the order I50 is the line A
Are allocated for 3 hours on August 25, 2 hours on 24th, and 3 hours on Line 25 for 3 hours on August 25, and that fact is stored in the allocated load storage unit 5. I have.

The capacity load allocated to the capacity frame of each day stored in the allocated load storage section 5, the information of the order I 50 stored in the order storage section, and the information stored in the capacity load storage section 4. Based on the capacity load per product, the operation unit 10 calculates the product item and the number of products having the capacity load assigned to the capacity frame on each day. On line A, the capacity frame on August 25 is 3
Time / 0.05 hours = 60 pieces, that is, a capacity frame for 60 pieces of film A is allocated. Similarly, a capacity frame for 40 films A is allocated to the capacity frame on the 24th. In the line B, a capacity load of 3 hours / 0.03 hours = 100 pieces, that is, a capacity load for 100 films B is assigned to the capacity frame on August 25. Similarly, the capacity load for 100 films B is assigned to the capacity frame on the 24th.

Then, the material load of each day relating to the same item and number as the capacity load of each day is calculated on August 25, which is the scheduled delivery date.
The allocation of the material load is started from the material frame of the day, and the material load is allocated to the material frame of each day retroactively from the scheduled delivery date. Therefore, on August 25, as the material load for 60 films A and 100 films B, the original volume A
The material load of 1.8 pcs and 1.0 pcs of original volume was increased on August 25.
Allocate to material frame of the day. Similarly, in the material frame of August 24, the material load of the original volume A1.2 and the original volume B1.0 was set as the material load for the 40 films A and the 100 films B, respectively. The material load is assigned to the material frame in accordance with the scheduled delivery date of August 25.

The assignment of the material load may be automatically performed by the calculation unit 10 as in the present embodiment, or the operator of the delivery date determination system may display the material frame to which the load has been assigned on the CRT display 8 or the like. Keyboard 7 while watching
May be input.

Step 6 (S6): Next, as a result of allocating the capacity load to the capacity frame, it is determined whether or not the allocation can be performed in time for the scheduled delivery date.

When all the material loads related to the order can be assigned to the material frames retroactively from the scheduled delivery date, the scheduled delivery date is set as the determined delivery date of the order I50. Then, information on the order I50 is stored in the order storage unit 12 together with the determined delivery date.

In the present embodiment, all the material loads related to the order can be assigned to the material frames, going back from August 25, which is the customer's desired delivery date and also the scheduled delivery date. August 25, which is the scheduled delivery date, is the determined delivery date of order I50. Then, information on the order I50 is stored in the order storage unit 12 together with the determined delivery date.

On the other hand, when allocating the material load related to the order to the material quota retroactively from the scheduled delivery date, the material load related to the item and the number calculated back from the capacity load allocated to the capacity quota on a certain day is the same as the day. If the material load cannot be allocated because the capacity of the material frame exceeds the capacity of the material frame, calculate the item and quantity of the product related to the material load that can be allocated to the material frame on that day (hereinafter referred to as “impossible day”). Thereafter, the capacity load relating to the item and the number is obtained, and the result is stored in the allocated load storage unit 5. And again,
Going back to step 3, the process starts from the assignment of the capacity load related to the order to the capacity frame. At that time, only the obtained capacity load is allocated to the capacity frame on the impossible day. Then, after the capacity load is reassigned to the capacity frame, the material load is assigned again. This operation is repeated until all the material loads can be allocated. And when it becomes possible to assign all material loads,
The final date to which the material load is assigned is the determined delivery date.

For example, let us consider a case where the material frame on August 25 is A1.2 for the original volume in this embodiment. The capacity load of the line A3 hours allocated to the capacity frame on August 25 is for 60 films A, and the material load for 60 films A is 1.8 for the original winding A. Therefore, the item and the number (film A60) calculated backward from the capacity load (line A3 hours) allocated to the capacity frame on August 25
Since the material load (1.8 pieces of the original volume) per unit exceeds the capacity of the material frame on that day (1.2 pieces of the original volume), assign the material load for the 1.8 pieces of the original volume. Can not. In this case, the capacity load related to the material load that can be allocated to the material frame on August 25, A1.2, is obtained. The original volume A1.2 is film A40
The capacity load related thereto is line A2 hours. Therefore, when re-assigning the capacity load to the capacity frame, the capacity frame on August 25
A capacity load is newly assigned to the capacity frame by allocating two hours. As a result, it is possible to allocate the capacity load and the material load related to the same product item and number to both the capacity frame and the material frame on August 25.

Incidentally, the material loads may be allocated to the material frames in order from the earliest day on which the capacity load relating to the order is allocated, rather than allocating the material loads to the material frames retroactively from the scheduled delivery date.

When the materials are stored in stock to some extent, the stock amount may be added to the material frame. That is, the amount of inventory stored up to a certain date,
The sum of the supply amounts of the materials to be supplied on that day may be used as the material frame on that day. For example, in FIG. 9, two original volumes A are supplied on August 21, but only one is to be used, so that one more original volume A is left. Assuming that one of the original volumes A is in stock, the supply volume of the original volume A is 0 on August 22, but the stock amount of the original volume A is one, so the material frame on August 22 is The original winding A becomes one. That is, the material frame after X days = the stock amount up to now + the total supply amount for X days−X
The total material load for the day.

Step 7 (S7): When the assignment of the material load to the material frame is completed, the determined delivery date is displayed on the CRT display 8. Once the delivery date is determined, order I50
The material load allocated to the material load and the capacity load allocated to the capacity load are stored in the allocated load storage unit 5.
Is stored. Further, the determined delivery date may be output from the printer 9.

According to the system configuration and procedure described above, in the present delivery date determination system, by inputting information relating to the order I50, it is determined whether or not the order I50 will meet the desired delivery date, and if not, when will the delivery date be reached? And other accurate information in a short time.

As long as the material frame and the capacity frame are set in advance, when an order (item, quantity, and desired delivery date) of a product is input, all processes are performed by the arithmetic unit without manual operation, and the load is reduced. It is, of course, possible to allocate and automatically determine the delivery date.

[0108] For example, a salesman receives an order at a business partner and produces information such as whether or not the order meets the customer's desired delivery date, and if not, when the possible delivery date will be. It is also possible to check in a short time from a portable terminal that can communicate with the department server.

In this embodiment, the capacity load is assigned before the material load is assigned. However, the material load may be assigned before the capacity load is assigned. Alternatively, the assignment of the capacity load and the assignment of the material load may be performed almost simultaneously.

In the present embodiment, when the desired delivery date cannot be met as a result of the load assignment, the delivery date is changed. However, the type or quantity of the product related to the order is changed, or the order is divided. By doing so, it may be possible to deal with it.

Further, the capacity frame and the material frame which have been set once may be changed. For example, when operating a factory on Saturday or Sunday, or when performing overtime, the capacity frame can be increased. Further, when a production line required to manufacture a product is unavailable or is saturated, a production line that is not normally used to manufacture the product is temporarily used (for example, usually, The production line for film A is line A, but when line A is saturated and line B is used temporarily, the capacity frame can be changed (the capacity frame for line B is changed to the capacity frame for line A). Or change the line type of the capacity load (change the capacity load from line A to line B)
It may be. At this time, it is preferable to assign priorities to a plurality of types of production lines to be assigned, and to change the assignment in the order of priority.

The capacity load and the material load once assigned to the capacity frame and the material frame may be reassigned. For example, if an urgent order B comes in after allocating the load related to order A and determining the delivery date, if there is no problem even if order A is slightly delayed from the delivery date, re-assign the load related to order A again. In this case, the delivery time is delayed, the load related to the urgent order B is allocated to the empty frame, and the desired delivery time of the order B is met.

However, the capacity load and the material load assigned to the capacity frame and the material frame within a predetermined period from the day are changed so that they cannot be re-assigned, and the capacity frame and the material load after the predetermined period from the day are changed. It is preferable that only the capacity load and the material load allocated to the frame can be changed and re-allocated from the viewpoint of preventing production management from being confused. For example, the capacity load and material load assigned to the capacity quota and material quota within two weeks from the day cannot be re-assigned, and the capacity load and material quota assigned to the capacity quota and material quota after two weeks from the day. The material loads can be assigned again. If the load can be re-allocated within two weeks, even the load related to the order whose production has already started may be changed (re-allocated), and the production process will be confused.

When an order is input by the production system having the load allocation system shown in this embodiment, the capacity load and the material load relating to the order are calculated, and the capacity load and the material load are allocated to the capacity frame and the material frame. May be performed to determine a delivery date, and at the same time, automatically issue an instruction to a production process based on the allocation result to perform the production of the product.

The load allocation method described so far
A computer may be used to start a recording medium on which a program for the delivery date determination method or the production method is recorded, and the load allocation system, the delivery date determination system, or the production system may be started by executing the program.
The recording medium is not particularly limited, and a floppy disk, C
D-ROM, MO disk, hard disk, and the like are included.

Also, as shown in FIGS. 8, 9, 10, and 11, the status of the load assigned to the material frame and the capacity frame is not displayed in a table format on the CRT display 8 or the like.
As shown in FIG. 2, it may be displayed in a graph format.

FIG. 12 is an example in which the load-allocated capacity frame and the load-allocated material frame shown in FIGS. 8 and 9 are graphically displayed. The mark 101 is a mark indicating that no more load can be allocated. Of course, the material frame and the capacity frame may be displayed separately.

The photographic film to be produced in the present embodiment is a product that requires a very wide variety of raw materials and requires a long period of time to be converted from raw materials to a product. In addition, the types of products are very diverse. Therefore, in order to shorten the time from receiving an order to shipping the product, a countermeasure has been taken by producing a master roll as an intermediate material in anticipation. In other words, from a very large number of kinds of raw materials, a kind of original roll less than the number of kinds of raw materials is expected to be produced, and a very large number of kinds of photographic films are produced using the original roll as a material. And since this original volume is produced by prospective production, it is difficult to always demand a large amount of stable supply. It is also conceivable to provide a stable supply of the original volume by storing the inventory, but a large inventory storage space is required to store the original volume,
Further, the performance of the original roll may deteriorate due to long-term storage, and it is not preferable to keep many original rolls in stock. Therefore, if production planning (assignment of material load) is performed in accordance with the type and amount (material frame) of the original roll that can be supplied, it becomes possible to supply a stable original roll as a result, and large inventory Also do not need.

[0119]

According to the present invention, it is not always possible to expect a stable supply of materials, such as products that require a long time to supply materials and parts, and products that are expected to produce intermediate materials. Even when producing a product for which it is difficult to obtain a material, it is possible to obtain an accurate delivery date in a short time after receiving an order, easily and without human intervention. Inventory can be reduced.

Further, since the progress of the order can be grasped in real time by both the production department and the sales department, there is no need to adjust between the live sales. Furthermore, the production load can be averaged.
