Abstract

PURPOSE:To reduce management manhours by shifting management which is mainly executed by a manual operation to that which is mainly executed by EDP and cancelling the asynchronism of a load plan and an execution plan. CONSTITUTION:In a workshop management system B, a pile table generation 1 is a load management function and it receives plan information on four to eight weeks later from a production management system A, accumulates it and updates it whenever alteration information occurs. A day unit plan 2 is an execution plan mechanism by individual days, it inputs plan information, parts fulfillment information and a holding manhour table and automatically generates the day unit plan as to present day+two days later, namely, one week later from a delivery read time. Furthermore, a release/manufacture instruction 3 sets the plan start day of present day+two days later to be a today's release instruction, links it to a warehouse management by using an automatic release function in a magnetic base and a manufacture instruction table gives the instruction of work to a manufacture shop.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manufacturing site management system which is used in a production information management system and which is positioned in a lower hierarchy thereof to eliminate the asynchronism between load plans and execution plans in work plan management.

[0002]

2. Description of the Related Art Conventionally, in a manufacturing site management system of a factory or the like, the work plan or work instruction is entrusted to the management of labor shortage of a production management person in charge and a full-time person such as a foreman of a manufacturing shop.

As shown in FIG. 2, a person in charge of production management [M]
Is the production plan [2]
The release order is determined based on the weekly schedule [2B] of [A] and the release schedule that is the supplement of the used parts to the production order, and the release request [2C] in time for the delivery date.
Is created and a cancellation instruction is given to the warehouse management system [2D].

After 3 days, the parts and shipping list [2
E] will be sent, and the manufacturing department will collate it with the weekly schedule [2F] and, in consideration of the number of man-hours possessed, will make a work schedule 2-3 days ahead.

[0005]

As described above, in the conventional man-made manufacturing site management system, the total amount of the weekly plan is divided into a plurality of times, the release order is determined based on the release schedule [2G], and , Creates a release request [2C] based on the determined release order, and issues a release instruction to the warehouse management system [2D]. It is also necessary to give manufacturing instructions to the manufacturing shop. As a result of implementing these,
There is a problem that the load is unbalanced on a daily basis, and the work shop needs to be re-planned, that is, re-planned.

The present invention solves such a problem, eliminates the asynchronization of the load plan and the execution plan, reduces the daily execution plan drafting man-hours, management man-hours, and is effective in information accuracy and information utilization. It is intended to provide a manufacturing site management system that is improved.

[0007]

In order to achieve this object, the manufacturing site management system of the present invention is a first process for creating a mountain table for each workshop in which the required man-hours are specified based on a weekly plan. Of the load plan and execution plan, including a second process for formulating a daily execution plan that takes into account the component satisfaction state and the number of man-hours held, and a third process for performing the start date adjustment process by online process and the automatic process. It has a configuration that eliminates asynchrony.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the manufacturing site management system of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of the embodiment.

In FIG. 1, this example is roughly constituted by a production management system [A] and a manufacturing site management system [B].

In the manufacturing site management system [B], the pile creation table [1] is a load management function and receives and stores plan information for 4 to 8 weeks ahead from the production management system [A]. Also, it is updated each time change information is generated.

Based on this plan information, the CAM database is referred to, and a mountain table is output 2-3 weeks before the start. Based on this pile table, the total amount of what is produced and what is to be produced is grasped, the required man-hours required, presence / absence of drawings, presence / absence of NC information, design change information, and the like are secured and manufacturing resources are secured and prepared.

In FIG. 1, a daily unit plan [2] is a daily execution plan planning mechanism, which inputs plan information, parts sufficiency information, and a possessed man-hour table, and the present date + 2 days ahead, that is,
Daily plan will be automatically created for one week after the delivery lead time.

Firstly, the actual draft logic extracts target data, that is, extracts from the plan information the date of planned completion date ≦ day unit plan final date. Secondly, the required man-hours for the extracted data including the order of missing items are summarized. Thirdly, the required man-hours summarized and the man-hours possessed on the possessed man-hour table are compared. In this comparison, the required number of man-hours that are evenly allocated on a daily basis to the extent commensurate with the possession is equal to or greater than the required man-hours, and the required man-hours for the forward allocation corresponding to the possession from the start date of the planning are less than the required man-hours.

However, in all cases, the shortage product order is subject to processing until the allocation method is determined, but in the actual allocation processing, the shortage product is excluded and allocated.

After the completion of the allocation on a daily basis, which is the setting of the commencement date, if necessary, a fine adjustment of the change of the initiation date on an order basis is performed. That is, the priority order or the lack-of-item correspondence is performed.

In FIG. 1, the release / manufacturing instruction [3] indicates that the daily unit plan is determined by the daily unit planning [2].
The planning start date of the current date + 2 days ahead is used as the cancellation instruction for today, and it is linked to the warehouse management by using the magnetically-based automatic cancellation function, and the work instruction is given to the manufacturing shop by the manufacturing instruction table.

As described above, in this embodiment, it is possible to delete the number of man-hours for formulating a daily execution plan, which takes into consideration the condition of parts satisfaction and the number of man-hours, for example, 3 hours per day. Further, it is possible to reduce the management man-hours by the automatic release instruction based on the daily execution plan and the production instruction, for example, 2 hours per day.

[0018]

As is apparent from the above description, the manufacturing site management system of the present invention shifts from the conventional manual-centered management to the EDP-based management and eliminates the asynchronism between the load plan and the execution plan. This has the effect of reducing the number of man-hours for formulating a daily execution plan in consideration of the situation and the number of man-hours, and reducing the man-hours required for management by an automatic cancellation instruction and a manufacturing instruction based on the daily execution plan.

Further, since the information is magnetized and the information is centrally managed, there is an effect that the information accuracy and the information utilization are effectively improved.
