Abstract: In order to solve the problems of complex user requirements analysis, low demand fit and insufficient user participation in the customization of existing products, the product deep-personalized customization method based on user requirements is proposed. The method maps the user requirements into the customized requirements by combining the user personality requirements expression model and the Quality Function Deployment (QFD), and it solves the product configuration by case retrieving and matching. The user can provide real-time feedback and adjustment to the customization solution through the visual interface, and deepen product customization degree with variant design. Finally, the optimal solution is provided to the users through the priority-degree evaluation so as to achieve a customization loaded with higher user participation and satisfaction. The method provides an effective way for deep-personalized customization and the feasibility of it turns out to be verified by the example of the product customization on cape.
