在产品方案设计阶段,明确用户群及其需求重要度关系到产品设计目标特性的质量。提出一种根据用户基本特征进行用户群划分,应用粗糙数排序筛选用户群的基本需求,对每个用户群按职业再进行用户子群划分,应用信息熵处理方法计算各用户子群的权值、用户群各项基本需求的重要度。该方法能有效的减小用户需求信息调查的模糊数值矩阵的阶数,能使产品设计者更准确的获取用户群及其需求信息。通过案例说明了其应用过程。
In the product design stage, a clear user base and its importance of demand related to the quality of the product design goal characteristics. This paper presents a basic requirement of user grouping based on user’s basic characteristics and the application of rough number sorting to select user groups. Each user group is divided into user subgroups according to occupations, and the entropy processing method is used to calculate the weight of each subgroup , The importance of the basic needs of the user base. The method can effectively reduce the order of the fuzzy numerical matrix of the user requirement information survey, which enables product designers to obtain more accurate user groups and their demand information. Through the case illustrates its application process.
