Abstract

A production planning system includes an equipment information data base, a product information data base, a quality historical information data base, an equipment priority calculation section, a line priority calculation section, a production history data base, and a production planning section. The equipment priority calculation section calculates priorities of kinds of equipment based on equipment information from the equipment information data base and product information from the product information data base. The line priority calculation section calculates priorities of production lines based on the product information and yields from the quality historical information data base. The production planning section arranges a production plan based on the priorities of kinds of equipment, the priorities of production lines, a delivery time of products and statuses of the production lines. As a result, a production plan in a production line for a wide variety of products can be arranged easily.

Claims6

Dependent claims

A production planning system selecting a production line suited for manufacturing on-order products from plural production lines each used for manufacturing a variety of products to arrange a production plan in the selected production line comprising:

an equipment priority calculation section calculating priorities of kinds of equipment that can be used for manufacturing said on-order products based on equipment information showing a kind of equipment applicable in each of said plural production lines;
and product information, including information on a kind of equipment suited for manufacturing said on-order products, and necessary for manufacturing said on-order products;
a line priority calculation section calculating priorities of production lines that can be used for manufacturing said on-order products based on quality information on each of a variety of products in each of said plural production lines and said product information;
and
a production planning section determining a production line suited for manufacturing said on-order products based on said priorities of kinds of equipment calculated in said equipment priority calculation section, said priorities of production lines calculated in said line priority calculation section, the number of said on-order products and statuses of said plural production lines to assign equipment necessary for manufacturing said on-order products and capable of being used to the determined production line and to thereby arrange a production plan for said on-order products.
