Dynamic optimization method for configuration change in complex product design

In order to reduce the impacts of configuration change in complex product design, a dynamic optimization method for configuration change in complex product design is proposed. First, a network model for characteristic relationships of complex product (CPCR) is built to describe the configuration scheme of complex product, with characteristics as nodes and relationships between characteristics in the configuration scheme as edges. Then, the impacts of change to different types of characteristics on other characteristics are analyzed to reveal the impact process of configuration change in complex product design. Next, according as the effects of change on upstream and downstream characteristics can be optimized and cannot be optimized, the dynamic optimization method for configuration change in complex product design is put forth, which integrates dynamic optimization for upstream characteristic changes and dynamic search of downstream characteristic changes. Finally, a practical application of the proposed method and a comparison of the proposed method with existing ones are suggested to verify the validity and applicability.
