Abstract: A 2D (Product and process dimensions) optimization model for mass customization is presented, and the optimization directions and methods of mass customization are described comprehensively. Furthermore, some cases are used as examples to support the descriptions on the meanings and methods of mass customization. The optimization goal to real Ize the lowest customization quantity is presented. The optimization in product dimension is divided into deepness and breadth optimization; The optimization in process dimension is divided into the moving back of customer order decoupling point and cutting down the proportions of customizing radio. Researches show that the mass customization is a gradually optimizing manufacturing system mode related with enterprise and a group of enterprises, optimizing the processes of design and manufacturing.

Key words: Integrated design and proess Manufacturing system optimization, Mass customization
