基于群体粗数的客户需求权重计算与分析

In order to guide enterprises to develop and design products, the product R&D needs to calculate the customer demand weight by customers requirements.Recent years,rough number method has gradually participated in the calculation and analysis of customer requirements weight.There are three kinds of methods to compute the group rough number: the geometric average method, the ratio weights synthesis method and the average weights synthesis method .This paper,on the basis of the initial scoring data of automotive customer requirements weight,contrasts these three kinds of methods and arithmetric average value method, using grey relational analysis and number consensus degree . Results shows that the ratio weights synthesis method has a better advantage in calculating the weight of the integrated rough number of customers.
