Abstract

PROBLEM TO BE SOLVED: To solve the problem that it is difficult to evaluate the excessiveness/ insufficiency of components related with a production plan, and to quickly facilitate and operate countermeasures to the excessiveness/insufficiency of those components in a control means based on a conventional display method for a product whose production plan is frequency changed since it is necessary to require the extremely large number of man-hours in order to perform a planning task for the product having tens of thousands of components, and to solve the problem that it is extremely difficult to globally analyze and control the original production plan or component arrangement plan, and to control the quantity of inventory since it is impossible to judge the level of influence of the control on the control of the other components. SOLUTION: The required quantity of materials based on a changed production plan is calculated, and the arranged situations or synchronized situations of components is simultaneously evaluated for each product, and when the excessiveness/insufficiency of the components is generated, the production plan or the component arrangement plan is easily controlled by this component synchronization control system. Also, the control is realized by a controlling means based on display in which charts and graphs are fused.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts synchronization management system, which calculates a material requirement based on a production plan, simultaneously evaluates a parts procurement state and a synchronization state for each product, and outputs a surplus part to a part. The present invention relates to a parts synchronization management system and a production planning method for facilitating adjustment of a production plan and a parts procurement plan when a shortage or a shortage occurs.

[0002]

2. Description of the Related Art A conventional method of managing parts synchronization related to a production plan involves a problem such as a large stock of parts and the like as in the production plan creation apparatus described in Japanese Patent Application Laid-Open No. 2-311250. In some cases, there is a device that assists in adjusting the stock quantity by analyzing and adjusting the production plan and the parts procurement plan. However, this device only supports the process of creating the plan, The evaluation of the situation, the detection of the adjustment point, and the decision of the adjustment must be made by the planner himself. For example, the Nikkan Kogyo Shimbun “illustration MRP term 5
00 selection "(by Hiroyuki Hirano) and Nihon Keizai Shimbun," Actual Inventory Management "(by Hiroyuki Hirano)
By confirming each one, the planner must evaluate the plan and detect adjustment points by himself.

[0003]

For a product such as a personal computer or an information communication device, which has a short product life cycle and fluctuates in the amount of demand, a production plan and a parts procurement plan are newly drafted, and then the market, etc. It is indispensable to review the plan in a certain cycle from the change in the situation. As a result, the expected consumption of parts and products dynamically changes in conjunction with the results of the plan review. Measures for surplus must be planned and implemented.

However, in order to confirm whether or not parts are prepared (synchronized) for each product with respect to a product production plan, as in the technique described in the above-mentioned "MRP Term Selection 500", After the MRP calculation processing, it is necessary to create an MRP plan table of parts a for a certain product shown in Table 1 below, one by one, and check the procurement status of the parts. In this example, a shortage occurs on the 8th, and an additional order for parts with a delivery quantity of 17 pieces and a delivery date of 8 days is required.

[0005]

[Table 1]

Further, in the example shown in Table 1, on the 5th, there are 50 units to be delivered with the order remaining, and as a result, the available stock on that day has increased to 53 units. This means that even if the parts are not delivered on the 5th, there is still room for 3 pieces (available stock: 53 pieces-planned delivery quantity: 50 pieces), and there is no need to deliver on this day. Therefore, it is necessary to consider extending the delivery date to 6 days as shown in Table 2 with respect to the remaining order on the delivery date: 5 days due to stock space and the like.

[0007]

[Table 2]

Conversely, if there is a shortage on the 6th as shown in part b of Table 3, then it is necessary to consider delivering the order date: the remaining order on the 6th one day before.

[0009]

[Table 3]

[0010] By performing such an operation for all parts related to the product, it is evaluated whether or not the parts are sufficient, and measures for shortage or surplus are planned and implemented. Therefore, for a product having a large number of parts, such as a personal computer and an information communication device, the production planning work is performed with a very large number of man-hours.

Further, as in the technique described in Japanese Patent Application Laid-Open No. 2-311250, a planner is not required to re-plan a plan based on a shortage or surplus of stocks of parts and products, but to make original production plans and parts. Attempting to adjust inventory levels by analyzing and adjusting procurement plans globally involves enormous difficulties.

That is, first of all, the extent to which the adjustment of the production plan or the like is affected is not immediately known to the person in charge of planning.

Second, the degree of effect of adjustment of a production plan or the like is not immediately known to a person in charge of planning.

Third, the planning staff cannot immediately know what matters when adjusting the stock quantity in the first place.

[0015] As described above, in the prior art, due to the evaluation of the parts procurement status and the synchronization status of each product in the production plan, and the inadequate function of changing and adjusting the production plan and the parts procurement plan, the man-hours for adjusting the production plan and the parts procurement plan are reduced. The problem is that it becomes huge.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and calculates a material requirement based on a production plan, and simultaneously evaluates a parts procurement state and a synchronization state for each product. It is an object of the present invention to provide a parts synchronization management system that facilitates adjustment of a production plan and a parts procurement plan when parts are in excess or shortage.

05). In response to the set lead time 14, the MRP development device 8 determines the start date of the item whose completion date has been determined previously (207, 208), and determines the required amount of the child item necessary for manufacturing the item. Completion date is calculated (209),
The required amount generated for the shop where child items can be manufactured is written to the data storage device 11 (210). Thus, the development at one manufacturing shop level is completed, so that the MRP control apparatus 2 performs the required quantity development at the further upstream manufacturing shop level, and repeats the above operation by the lead time calculation apparatus 1 and the MRP development apparatus 8. (212, 213). Thus, the production plan is generated (MRP regeneration).

Next, other functions of the MRP control device 2 will be described.

In the parts synchronization management system, various measures such as adding a parts delivery schedule and adjusting a scheduled delivery date and a scheduled delivery quantity of a part are performed with respect to a production plan. Since the required amount fluctuates, it is necessary to perform the component required amount calculation again. At this time, similarly to the production plan generation, the MRP control device 2 executes the change of the production plan by controlling the execution of the lead time calculation device 1 and the MRP development device 8.

Hereinafter, the production plan change processing of the present system will be described in detail with reference to FIGS.

The MRP control device 2 controls the operation of the MRP expanding device 8 and writes the addition of the part delivery schedule and the adjustment of the scheduled delivery date and the scheduled delivery amount of the component to the data storage device 11 (301). Thereafter, the MRP developing device 8 operates to redeploy (net-change) the required quantity for the item to be produced at the changed location and its child items, and outputs the result 3 (302). The MRP control device 2 controls the execution of the lead time calculation device 1 and the MRP development device 8 so as to repeat the above operation if there are still small items affected (303). In this way, the change of the production plan (MRP)

Hereinafter, the display / display of the data input / output device 12 will be described.
An operation of the embodiment of the component synchronization management system will be described focusing on the operation.

The data input / output device 12 is a conventionally known data input / output device in a computer, for example, a data input / output device provided with a CRT display device, a keyboard and a mouse.

Next, the function of the component procurement status analysis device 7 in the component synchronization management system will be described.

In FIG. 4 showing the initial screen of the parts synchronization management system, by picking the "synchronization check" command menu 41 of the command menu with a mouse or the like, the parts procurement status analysis instruction 20 of FIG. 1 is instructed. You.

The parts procurement status analysis device 7 receives the parts procurement status analysis instruction 20 and sends an MR from the data storage device 11 to the MR.
P execution result 21 is input.

Here, the MRP execution result includes a consumption schedule (item, quantity, delivery date, etc.), a stock amount, and a delivery schedule (item, quantity, delivery date, etc.) of each product / part.

The parts procurement status analysis device 7 searches these consumption schedules, inventory amounts, and delivery schedules of unordered products to find out at which time the inventory amount and the planned delivery amount of unordered products can cover the consumption schedule. Is evaluated for each item, and the result 19 is output to the data input / output device 12.

FIG. 5 shows an output screen of the part procurement status analysis result of the present invention. The parts synchronization evaluation display table 501 in FIG.
The vertical axis represents the parts 502, the horizontal axis represents the stock amount 503, and the scheduled delivery amount 5
04, the total required amount of parts (planned consumption amount) is shown in the matrix 505 on a daily basis (period can be weekly, seasonal or monthly).
In the matrix, the portion indicated by the dark hatching 506 is covered by the stock amount, the portion indicated by the light shading 507 is covered by the expected delivery amount, and the portion indicated by the light shading 508 is displayed by the light shading 508. Portion is covered by the scheduled delivery amount, but during the period when the delivery schedule has to be shifted backward because there is enough delivery time, the portion indicated by light shaded 509 cannot be covered by the stock and the scheduled delivery amount During the period when it is necessary to shift the unscheduled delivery date ahead, the part indicated by light shaded 510 cannot be covered by the stock and the scheduled delivery amount, and it is necessary to add the unscheduled delivery schedule The period is displayed.

Referring to FIG. 5, a display method of the present invention for facilitating the understanding of parts procurement / delivery status will be described based on the examples shown in Tables 1 and 2.

For example, for item a, the scheduled consumption amount of 27 pieces per day is covered by the stock quantity of 14 pieces and the planned delivery quantity of 50 pieces. Is displayed in half. Since the amount to be delivered can be covered from 2 to 5 days, it is indicated by thin hatching 507. Although it is covered by the scheduled delivery amount on the 6th, the delivery date has a margin and it is necessary to shift the delivery schedule backward, so it is indicated by thin hatching 508. In other words, by checking whether or not the thin hatching 508 exists in the hatching graph of the parts, it is possible to easily narrow down the parts whose delivery schedule can be shifted backward because the delivery date has a margin. .

Referring to FIG. 5, a display method according to the present invention for facilitating grasp of another parts procurement / delivery status will be described based on the example of Table 3.

For example, like the item b, the same as the item a from 1 to 5 days, it is not possible to cover the inventory and the scheduled delivery amount on the 6th, and it is necessary to shift the scheduled delivery date of the remaining order ahead. This is indicated by a thin hatching 509. Similarly, it is necessary to shift the delivery date of the remaining order beforehand because it is not possible to cover with the stock and the expected delivery amount by checking whether the thin hatching 509 exists in the hatching graph of the parts. You can narrow down a certain part.

According to such a display method, it is possible to quickly grasp the parts procurement status and easily extract parts for which measures need to be considered.

In this display, as shown in FIG. 6, a display component narrowing button 6 is displayed from the component synchronization evaluation display table 601.
By selecting 2, it is possible to narrow down 62 the components used for each product.

As a result, as shown in FIG. 7, a component synchronization evaluation display table 701 of only the components a and b used for the product X can be displayed, and the synchronization status of the components with respect to the production plan of this product can be displayed. It becomes possible to grasp immediately. In this example, it is shown that the delivery date of item a has a margin at 6 days and the delivery schedule needs to be shifted backward, and that the delivery date of the remaining order must be shifted earlier because item b is insufficient. Is shown. Therefore, the production plan of the product X indicates that unless the scheduled delivery date of the item b is shifted ahead, it is impossible to produce due to missing parts.

A method of planning a countermeasure performed after grasping these situations will be described below with reference to FIGS.

First, an example will be described in which the delivery date has room and the scheduled delivery date of the remaining order is shifted backward.

This is similar to the shift of the delivery schedule, as shown in FIG.
From the part synchronization evaluation display table 91 of only the parts a and b used for the product X, the thin shaded area 92 (as of the 6th day) of the part b for which the delivery schedule needs to be shifted forward is indicated by a mouse or the like. When the pick is made using, the part order remaining display is shifted 9
3 is displayed, and the order number requiring forward shifting: # 02, the order quantity: 50 pieces, the delivery date: 7 days, the forward shifting date: 6 days are displayed. After confirming this display content, when executing this countermeasure, the user selects the execution button in the part order remaining front shift display 93. Here, the example in which the display 93 is automatically set to an appropriate value has been described, but the object of the present invention can also be achieved by the user arbitrarily setting the shift date or the like. Therefore, 6
In addition to shifting the date, the shift date can be set to five days or the like, taking into account the margin of the delivery date.

According to these two scheduled delivery date adjustment operations,
Execution of the MRP calculation is performed.

Output to From the calculation result 21, the parts procurement status analysis device 7 evaluates, for each item, whether or not the inventory amount and the scheduled delivery amount can cover the consumption schedule, and outputs the result 19 to the data input / output device 12. .

Next, an example of adjusting the scheduled delivery amount with respect to the remaining order will be described. As shown in FIG. 10, in the part synchronization evaluation display table 101, for the part c covered by the scheduled delivery amount (the thin shaded area 102) from the first day (1st) to the last day (6th day), Adjust the scheduled delivery of parts. The stock of the part c is 36 pieces (14
+ 100-14-19-45), and according to the display of the present invention, it can be easily determined that the scheduled delivery quantity needs to be adjusted in order to prevent excess stock.

As a specific operation method, when the picked-up parts delivery quantity display 103 is picked by an input means such as a mouse, the order number: # 0 is displayed on the part order quantity change display 104.
3. Order quantity: 100 pieces, change quantity: 64 pieces, delivery date: 5 days are displayed. After confirming this display content, when executing this countermeasure, the execution button in the parts order quantity change display 104 is selected. Here, the display 104 shows an example in which a value calculated as a standard by the internal setting is output, but the user can arbitrarily input a change amount.
The MRP calculation is executed according to the scheduled delivery amount adjustment operation.

When an instruction to change the scheduled delivery amount of a component is issued, the data input / output device 12 shown in FIG. Out. The scheduled parts delivery quantity adjustment device 40 adjusts the scheduled delivery quantity adjustment result and the MRP execution instruction 39.
