Abstract: To make collaborative consideration for product platform configuration in the process of product family design's modularity,the hierarchical joint optimization for modular design coordinated with product platform configuration was researched A 0-1 nonlinear bi-level programming model was developed,which showed the leader-follower relationship between modular design and product platform configuration.To solve this model,a nested genetic algorithm was designed.The proposed model was applied to a case study of automotive platforms modular design,and the joint optimization result was compared with results driven by two-stage approach and all-in-one method so as to prove the advantage of this joint optimization model.

Key words: modular design, platform configuration, bi-level programming, nested genetic algorithm, product development
