Abstract: Design for mass customization(DFMC) is one of the key technologies in MC research and implementation. One important characteristic of current DFMC mode is that product design and manufacturing will be constrained heavily by customer orders, which makes optimization of enterprises’ manufacturing attributes hard to achieve. To solve this problem, the thought of customer requirements collaborative optimization between customers and enterprises’ is brought forward. It is considered that customer requirements parameters have strong correlation to enterprises’ parameters of product design, product manufacturing, management and operation. In addition, customer requirements normally have considerable scope of variation. Therefore, through the integration of customers and enterprises and coordinating customer requirements parameters with enterprises’ manufacturing parameters, it will be possible to achieve overall optimization and consequently improve customers’ satisfaction and enterprises’ performance. Then, a multiple objective optimization model for customer requirements collaborative optimization is set up. An internet-based operation mode and a realization scheme are brought forward. A case study shows that the customer requirements collaborative optimization is practical.
