Abstract: To avoid the infeasible or suboptimal product development schemes resulting from separating the process of product family design and supplier selection,and to evaluate the design scheme of product family design from multiple perspectives,a new multi-objective optimization approach for integrating supplier selection into product family design was proposed,and a multi-objective mathematical model with objectives of maximizing the total profit and minimizing the supply risk of a product family was established.Meanwhile,the influence of product affective attributes on consumer choice behavior was considered in the model to more accurately analyze consumer preferences and optimize product family.Non-dominated sorting genetic algorithm was developed to solve the established optimization model and a case study was conducted to illustrate the feasibility and rationality of proposed approach and algorithm.
