Research on Intelligent Design Method of Complex Products

In order to accelerate the speed of product development and improve efficiency, the paper proposes a combination of genetic algorithm and case-based reasoning to design complex products. The genetic algorithm is applied to the overall design of the user's design requirements, and then according to the multi-level characteristics, the complex products are subdivided, and each part is coded, selected, crossed, and mutated. Finally, a new solution is selected and stored. The stored solution is used as a case library, and the case is matched and modified by case reasoning, and the newly generated case is stored in the case library. Detailed parameters and dimensions of each part of the structure and components can be obtained by case reasoning.
