Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a production instruction method, and particularly to a work instruction method suitable for giving or modifying work instructions at a work site.

[Conventional technology]

The conventional work instruction method aims to reduce the number of man-hours.

(1) Production information for parts and products is summarized from the initial process to the final process, and production drawings, work instruction sheets, and work cards are attached to the relevant parts.

(2) In order to avoid the occurrence of no work in each production process due to a lack of work instructions, the amount of work instructions given to each unit period (usually 1 in the case of individual made-to-order factories) In addition to the amount of work per week), supplementary information is also included.

With this conventional method, product specifications rarely change;
Initially, it was an economical and effective method when it was sufficient to carry out the work as specified1, and when the delivery conditions were not too strict and production time was available.

However, in recent years, product specifications have become increasingly diverse, and product specifications are changing more frequently. Therefore.

Problems such as delay in delivery due to neglect of work order, difficulty in changing the contents of work instructions, unclear contents of work instructions, and loss of production information recording media are becoming apparent.

Therefore, a work instruction system has been proposed, as disclosed in Jikai No. 62-162450, in which a terminal device is provided for each production process to output and display production information and input information such as production progress results. However, it only displays production information, but does not take into account the number of components that can be produced depending on the inventory status.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into consideration the work order determination by the work progressor or the prompt decision of whether or not to respond to a sudden request.

(1) Due to frequent changes in daily plans and the presence of a large number of shared parts, it takes time to grasp the status of each inventory.

(2) After the contents of (1) have been clarified, the work manager must decide whether or not to proceed with the production based on the production instructions.

(3) When a sudden customer request arises, it takes a lot of effort to check whether the request can be met or not by checking the amount of parts in stock and calculating the allocation.

There was a problem.

An object of the present invention is to clarify the content and order of work, to facilitate changes to the content, and to reduce the work of changing inventory quantities in inventory management.

[Means to solve the problem]

The above purpose consists of a means for inputting production-related data, a calculation means for processing the input data, and a means for displaying the calculated results. This is achieved by displaying various information related to the following.

Namely.

(1) One day's production instruction 1 work order for a certain work process group.

Screen for displaying the number of products that can be produced and changing production instructions (2) Screen for displaying the production schedule of the product, the number of completed products, and the progress (scheduled, number of completed products) of the parts used (3) Product schedule, finished product (4) A screen that displays the number of parts that can be produced, the number of parts in progress, and the number allocated for the product. (4) The work progressor looks at the screen that inputs the number of completed products, confirms the schedule, and determines the number of parts that can be produced. This is achieved by interactively modifying production instructions to determine changes in the production order and to determine how to respond when sudden requests occur.

[Effect]

Production instruction display (correction of production order/instructions) Work process groups are displayed on a matrix with the product name, number of instructions, completed quantity, producible quantity, and priority in rows and the production order of each process in columns. The work status (starting, 1 work in progress, completed) and color are associated with each other and displayed in different colors. This makes it possible to grasp the work content in one work process group and the number of products that can be produced for each instruction. The work progressor can check the breakdown of the number of products that can be produced for each instruction on the (4) in-process display screen by model. Additionally, on this screen, production order and instructions can be changed in response to sudden customer requests.

(2) Progress display by model The progress status of a product is displayed in real time, with each process in a row and the number planned for the current month and the cumulative information up to the previous day (number of instructions, number of completed items, etc.) in columns. Using this screen, you can discover parts used that are likely to be a bottleneck in manufacturing a certain product.

(3) In-process display by model (product #) Planned number, actual number, producible number and names of parts used for each product, number of in-process items, allocated/planned number for the product,
Display the number of completed products by product (product #). This screen allows you to
Check the breakdown of the number of products that can be produced and remove bottleneck parts.

(4) Production performance input Enter the number of completed items, number of defective items, etc. for the work instructions.

Using the above four screens, the production order can be quickly grasped by performing interactive operations and viewing the respective production instructions and possible production quantities in a visually appealing manner.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.
