In mass customization environment, how to quickly meet customer's demands by cluster order demand was proposed in this paper. The customer demand model was established using handling the mass customer orders. In order to improve the efficiency of the configuration, the product family model was established based on the composition of custom module and universal module. By extracting the attributes of product family and demand characteristics of customer orders, the match relationship between order needs and product family was created by similarity, and product configuration program was obtained. Finally, an example of a reducer is presented to verify the feasibility of the proposed method.
