[Action]

In the present invention, the means for editing the product completion progress distribution map calculates the deviation of the scheduled completion date with respect to the delivery date from the delivery date and the scheduled completion date of each product with respect to all the products to be produced, and the scheduled completion date for the delivery date. Edit the data to display on the screen a diagram that expresses the number of products as a histogram based on the deviation. As a result, the tendency of when the whole production target product is completed with respect to the delivery date can be known, so that the quality of the entire plan can be evaluated.

The means of editing the production progress chart for each product is the planned start date, the planned completion date, the delivery date, the planned total work man-hours from the start to the completion, and the actual completed work man-hours for all products to be produced. The scheduled start date, scheduled completion date, and delivery date of each product will be displayed according to the scale of the date, for example, in the form of a Gantt chart, and a diagram will be displayed that also shows the percentage of completion by the time of completion. Edit the data to do so. As a result, it is possible to know when the individual products to be produced have started and are completed, or to what extent they are completed, so that the plans and progress of the individual products can be evaluated.

The means for editing the production progress chart for each part is for each product, for each part that composes the product, including the scheduled start date and time of each process from the initial process to the final process, the scheduled completion date and time, the number of work steps, and the completed amount From the actual completion work man-hours, according to the scale of the date, the scheduled start date and time of each part, each process, the scheduled completion date and time,
For example, the data is edited in order to display it in the form of a Gantt chart and also to display a diagram showing the completed parts. As a result, as a breakdown from the start to completion of the relevant product, how the individual parts that make up the product are manufactured, from the initial process to the few processes, or to what part Since it is possible to determine which part is a bottleneck and which process is a bottleneck in manufacturing the product, it is possible to take measures in advance to complete the product on time.
