Research Of The Product Customer Requirement And Technical Characteristics Deployment

In the design production facing of improved products, enterprise must continually obtain demand information from customers, and provide customers with products that better meet their needs. The mapping process of customer requirements and technical characteristics is an important part of product definition. With the purpose of transforming customer requirements into product technical characteristics, it needs the corresponding research on the customer requirements and technical characteristics of configuration, and then offer some new ideas and methods for innovative design of the products.On the basis of depth studying and analyzing the research results of the domestic and foreign relevant fields and interrelated data, the paper combined the problem of customer requirements and technical characteristics of configuration in Electric vehicle product development, research on some key technologies and methods to customer requirements process and the optimal configuration technical characteristics, for products throughout the design process always focus on customer requirements unfolding, so that products can maximum satisfy the customer requirements and provide effective support and a more complete solution in the implementation of the initial stage of product design.Firstly, researching customer requirements information acquisition and modeling technology. Developed a Web-based customer requirements information database system application of ASP, Access, Dream weaver and other technologies, including customer requirements information online access, customer requirements information based on similarity with induction, the expression and storage of requirements template Case-based reasoning (CBR) technology, and use the success of product case study for customer requirements group classification. Secondly, further research on the application of neural network and genetic algorithm in customer demand and technical characteristics configuration technology, and then summarizes the method for determining the technical characteristics; Established the BP network model of the mapping relations between the customer requirements satisfaction and the eigenvalues of technical features, and among the technical characteristics themselves, make its BP network model can be applied to genetic optimize, to realize the target of product technical characteristics innovation. Lastly, on the basis of existing case information, the paper combined with innovative design method, takes the electric car for example, through the program realization and validates the effectiveness of the method of innovative design.
