基于模糊数据包络分析的产品质量功能展开

Quality Function Deployment Based on Fuzzy Data Envelopment Analysis

提出一种用模糊DEA确定产品规划质量屋中各工程特性权重的方法。基于绿色设计的思想,除考虑顾客需求外,再考虑环境和成本的情况下,建立了质量屋。同时采用三角模糊数表示质量屋中的各种元素,提出用模糊DEA确定各工程特性权重。将每一个工程特性看作是一个决策单元,该工程特性与每一顾客需求的关联程度看作是输出指标,环境和成本看作是输入指标,决策单元的效率指标值体现了该工程特性的重要程度。最后,算例分析证明该方法的有效性和正确性。

A new method to rate the engineering characteristics in house of quality of product planning is proposed based on fuzzy data envelopment analysis. Based on the concept of green design, besides the customer needs, with respect to the environment and cost, the house of quality is established. At the same time, triangular fuzzy numbers are used to represent all the factors in HOQ. Then, a new method based on fuzzy DEA is used to rate the engineering characteristics, in which, each engineering characteristic is considered to be a decision making unit, the relationships between the engineering characteristic and all the customer needs are regarded as output factors, while effect on the environment and cost are regarded as input factors. The importance of the engineering characteristic is determined by the efficiency score. Finally, a numeric example is used to illustrate the validity and correctness of the method.
