Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pre-scheduling method, and particularly, in the method of creating each plan from production plan creation to production execution plan creation in a production factory, the load of plan schedule adjustment and inter-site adjustment. The present invention relates to a pre-scheduling method that creates data at a pre-adjustment stage.

[0002]

2. Description of the Related Art Between the conventional production plan and the manufacturing execution plan, there is no idea of preparing data before the load adjustment such as schedule adjustment and inter-site adjustment. As shown in the block diagram of the production management system, the data of the production plan 101 created by the production plan creation system 100 is also used in data structure when the load adjustment from the production plan creation to the production execution plan creation is performed. The load adjustment was performed by directly inputting the load adjustment system 102 without changing the data capacity. Therefore, the load adjustment system 1
In 02, the input production plan data is displayed directly in the load state, and the load adjustment personnel can make the load adjustment by their own judgment while confirming all the displayed load states. Was there.

[0003]

In the conventional production control system of the related art described above, the data of the production plan created by the production plan creation system is used when adjusting the load from the production plan creation to the production execution plan creation. Since it is used directly, the load coordinator must adjust the load in consideration of both the parts production plan and the final product production plan, and the adjustment time increases due to the increase of items to be considered when performing the load adjustment. At the same time, there is a problem that the adjustment quality deteriorates because the matters to be considered are omitted from the plan. In addition, if the load adjustment personnel change, the items to be considered during load adjustment may change, and it is not possible to maintain uniform load adjustment. In consideration of the above-mentioned problems, in order to reduce the load on the person in charge of load adjustment, it is necessary to adjust the load in consideration of many plans created by the production plan creation system. The load on the entire information processing system in operation may be large and may affect other processing, while the hardware used for this is very expensive due to the large amount of processing power and storage capacity required. There is a problem that it becomes a thing.

It is an object of the present invention to convert the plan information used in the production management work into information that can be easily judged by a person and whose load can be easily adjusted, so that the pre-scheduling system enables efficient work execution. To provide.
