Abstract: The fundamental requirement of product design under Mass Customization (MC) circumstances is the module design of the groups of parts, and the rapid reconfiguration of these groups is the timely way to meet the specific customer demand. It′s a challenge to the traditional way of product design. The paper presents a model for the product design under MC circumstances, and the Bill of Material (BOM) of the specific product is dynamically calculated by breaking up the BOM of the relative groups of parts in the model, so that the process sets and the production resources, and the model system can fit the requirement of Just In Time (JIT) theory perfectly.

Key words: mass customization, bill of material, just in time, production management
