为了以经济和高效的方式实现顾客需求满意度的改进目标,提出了产品规划质量屋中基于互反偏好信息的顾客需求综合重要度确定方法。在该方法中,首先根据本企业及竞争对手产品的互反偏好信息和各项顾客需求的竞争性评价,利用偏差最小的原理建立对应于每一个顾客的、确定顾客需求竞争性重要度的优化模型,通过拉格朗日函数来求解这些优化模型,进而确定产品规划质量屋中的顾客需求竞争性重要度;其次,利用比例标度法和层次分析法的集成方法,确定改进后的产品对满足顾客需求的提高程度;最后,利用层次分析法对顾客需求的基本重要度、顾客需求的竞争性重要度和改进后的产品对满足顾客需求的提高程度进行合成以确定顾客需求的综合重要度。以某企业彩色电视机的产品设计为实例,说明方法的应用。
For achieving the improvement goals of the satisfactions of CRs in an effective and economic way,a method for determining the synthesis IRs of CRs in PPHOQ was proposed based on multiplicative preference information(MPI).According to the competitive evaluations of CRs' satisfactions and the MPI of the products of a company and its competitors,a model for determining the competitive IRs of CRs corresponding to every customer was built by using the principle of minimized deviations,and this model was resolved by using Lagrange function,and then the competitive IRs of CRs in the PPHOQ were determined.Secondly,based on the integration of analytical hierarchy process(AHP) and scale method,the satisfaction elevation rating(SER) of a CR for the company improved product was determined.Lastly,based on the combination of the basis IR,the competitive IR,and the SER of every CR,the synthesis IRs of CRs were determined by AHP.A case study of a color TV in a corporation was provided to illustrate the application of the proposed method.
