Joint optimization of complex product variant design responding to customer requirement changes

This is the authors' abstract. We don't add key points for this paper.

Changing customer requirements always poses a great challenge to designers in complex product design. Due to the complicated coupling relations between components, it is difficult to improve the efficiency of product reconfiguration. Therefore, this paper proposes a joint optimization model of complex product variant design responding to customer requirement changes. Based on synthesizing the advantages and deficiencies of “Scaled-based” and “Module-based”, a UB-BU hybrid approach is developed to improve the search efficiency and reduce conflicts. Then, a joint complex product variant design bi-level optimization to maximize customer satisfaction and minimum cost is established. As a solution, the genetic algorithm embedded double iteration comparison rules (GA-DICR) is developed based on canonical genetic algorithm. Finally, the method and model are proved to be effective in the Clutch variant design. The results can provide way of allowing the decision-makers to respond rapidly to customer rudiments changes request.
