产品规划中基于市场竞争的关联关系强度估计

Determination of Functional Relationship Measures in Product Planning Based on Competitive Evaluations

在质量屋的构建过程中,顾客需求与工程特性之间关联关系强度的估计是一个关键步骤。针对该关联关系强度具有多属性决策的特征,提出了面向竞争评价的质量屋中关联关系强度的估计方法。在该方法中,首先对本企业及其竞争对手的产品进行竞争性评价,以获得规范化的顾客需求和工程特性的竞争性评价;其次,根据这些竞争性评价,利用多属性决策方法建立相应于每一项顾客需求的工程特性重要度的优化模型,并通过拉格朗日函数来求解这些模型;最后,引入顾客需求与工程特性之间关联关系的类型因子概念,确定顾客需求与工程特性之间的关联关系强度。以某企业单缸洗衣机的产品设计为实例,说明该方法的应用。

Determination of FRMs between CRs and engineering characteristics ECs is a crucial step in constructing house of quality（HOQ）.Because the multiple attribute decision making characteristic of the FRMs,an integrated approach for determining the FRMs was proposed by exploiting competitive evaluations.Firstly,to acquire the competitive evaluations of CRs and ECs,the products of a company and its competitors were evaluated;secondly,according to these competitive evaluations,a model for determining the importance ratings of ECs corresponding to every CR was built by using multiple attribute decision making（MADM） method,and this model was resolved by using Lagrange function;lastly,by introducing a concept of type gene of a functional relationship,the FRMs between CRs and ECs were determined.A case study of product development of a singular-vat washing machine in a company was provided to illustrate the application of the presented approach.
