Abstract: To decrease raw material and energy consumption and to reduce environmental pollution during the product development process,the modular and upgrading design of product were used to extend the product life cycle and maximize the utility of products.Aiming at the joint optimization problem of modular product architecting and its eco-upgrading design,a leader-follower joint bilevel optimization model was proposed in which the designer of the upper-level model as the leader,decided on the architecture and configuration of product to maximize product utility per cost,and the manufacturer of the lower-level model as the follower,decided on the product upgrade configuration to maximize total revenue of products in multi life cycle.Then a nested bilevel genetic algorithm was developed to solve the proposed model.A case study was introduced to demonstrate the effectiveness of the proposed model and algorithm.

Key words: modular architecting, eco-upgrading, bilevel optimization, nested genetic algorithm, product development
