Whether the design of product innovation can highly match the customer demand is the key to extend the product life cycle, and it is also the basis for enterprises to carry out continuous production and operation. The first step of product innovation is to identify the relationship between customer demands and design factors of product innovation. This paper focuses on the problems of market control, due to the wide range and deep level of knowledge from customer demands in the process of product innovation. To better meet the customer demands, combined with Entropy Theorem, Prospect Theory and Grey Correlation Method, this paper puts forward a method of importance of design factors of product innovation considering customer demands. First, the Entropy Theorem and Prospect Theory are introduced to calculate the importance of demand factors from the perspective of customers and experts. Second, the priority ranking of design factors of product innovation from the perspective of customer demand is calculated through Gray Correlation Method and Fuzzy TOPSIS. Finally, this method is availability and feasibility thought taking the continuous innovation of electric vehicle as an example.

产品创新的设计能否与客户需求高度匹配，是延长产品生命周期的关键，也是企业进行持续生产经营的基础。产品创新的第一步是确定客户需求与产品创新设计因素之间的关系。由于产品创新过程中来自客户需求的知识范围广而知识渊博，因此本文重点讨论了市场控制问题。为了更好地满足客户需求，结合熵定理，前景理论和灰色关联法，提出了一种考虑客户需求的产品创新设计要素重要性的方法。第一的，引入了熵定理和前景理论，从客户和专家的角度来计算需求因素的重要性。其次，通过灰色关联法和模糊TOPSIS法，从客户需求的角度出发，对产品创新设计要素的优先级排序进行了计算。最后，以电动汽车的持续创新为例，该方法具有实用性和可行性。
