[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a display device for schedule planning and work results at a production site, and is particularly useful for quickly and accurately grasping the situation in process control using a computer terminal. The present invention relates to a process control data display device suitable for displaying process control data.

[Conventional technology]

Conventionally, as described in Japanese Patent Application Laid-Open No. 58-154012, as a method for detecting abnormalities in production process control, the display contents are changed step by step while comparing the plan and actual results to induce the cause of the abnormality.
There are suggestions for what to do.

But in production. Whether it is plan data or actual data,
Even the same data can have different meanings and values for the people who handle the data. Although the above invention is effective for investigating the cause of abnormalities in process control operations, it cannot be said to be effective for other purposes.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology has a problem in that the value of data is grasped and used from only one aspect, and the same data is not used even though it can be used for various purposes.

The purpose of the present invention is to enable schedule planning of when work should start, completion prediction of when work will be completed, and performance management or history management of when work is completed, as part of process management. An object of the present invention is to provide a process control data display device that provides the following advantages.

[Means for solving problems]

The above purpose is to display production planning data and actual data, which are the basis of process control, as well as a means for editing a product completion progress distribution chart that expresses the completion progress status of the entire product to be produced relative to the delivery date, and A means for editing a production progress diagram by product that expresses the transition in production of a product, a means for editing a production progress diagram by part that expresses the transition in production for each component under each product, and the above product completion progress distribution diagram,! This is achieved by providing means for selecting and displaying the I-product production progress chart and the 1-part production progress chart in an interactive manner step by step.

[Effect]

In the present invention, the product completion progress distribution diagram editing means calculates the deviation of the scheduled completion date from the delivery date from the delivery date and scheduled completion date for each individual product for all products to be produced, and calculates the deviation of the scheduled completion date from the delivery date. Edit the data to display a diagram on the screen that represents the number of products as a histogram based on the deviation.

As a result, it is possible to see trends in when all products to be produced will be completed in relation to the delivery date, so it is possible to evaluate the quality of the overall plan.

The means of editing the production progress chart for each product is based on the scheduled start date, scheduled completion date, scheduled number of man-hours from start to completion for each product for all products to be manufactured, and the actual number of man-hours completed for only the completed part. Display the scheduled start date, scheduled completion date, and delivery date of each product in the form of a Gantt chart, for example, according to the 1-day scale, and also display a diagram showing the percentage of completion until completion. Edit the data for As a result, it is possible to know when each product to be produced is started and completed, or to what extent it has been completed, so the plan and progress of each product can be evaluated.

The means for editing the production progress chart by parts is 1. For each individual product, the scheduled start date and time of each process from the first process to the final process and the scheduled completion date and time for each part that makes up the product.

1 from the work man-hours and the actual completed work man-hours only for the completed part
The scheduled start date and time of each part and each process, and the scheduled completion date and time of each part and each process are displayed in the form of a Gantt chart, for example, according to the date scale, and the data is edited to display a diagram that also shows the completed parts. As a result, it is possible to determine how the individual parts that make up the product are produced from the initial process to the final process, or to what extent they are completed, as a breakdown of the process from the beginning to the completion of the product. By knowing this, it is possible to determine which parts and which processes are bottlenecks in producing the product in question, and take countermeasures in advance to complete the product on time.
