What is Production Planning System?

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.
