A synthetic model of multi-level production planning and control integration is brought forward, which integrated Master Production Schedule , Material Requirements Planning , Shop Floor Control , order acceptance control, order release control and process control into a whole. Besides, a new method of production management—— Theory of Constraints is introduced into the traditional MRP, and a method to integrate TOC with MRP is put forward. As a result, a system of production planning management for ceramics enterprise is developed. Then several problems of shop planning and control for ceramics enterprise including the modeling of production line, the optimized utilization of kiln, the complement and due-date of products are discussed. A mathematical programming model of equalization production for ceramics production line is set up. An optimized model is put forward, which uses genetic algorithm to solve the sequencing problem of ceramics before the kiln.
