摘要
针对质量功能展开(quality function deployment,QFD)中评价信息的模糊性和不确定性问题,考虑球型模糊具有独立确定隶属度、非隶属度和犹豫度的优势,采用球型模糊数处理专家语义评价信息,将供应商和顾客需求映射为工程特性。针对现有模糊QFD分析中反模糊化造成信息损失以及没有考虑决策者心理偏好的问题,采用TODIM(交互式多准则决策方法葡萄牙语缩写),考虑专家规避风险的心理偏好,通过计算工程特性的总体优势度进行其重要度分析。为验证该方法的有效性,以某电动汽车产品服务系统为例,进行工程特性重要度分析、损失规避系数灵敏度分析,并对比了不同多属性决策方法的工程特性排序结果。结果表明,所提方法能够解决评价信息的模糊性和不确定性问题,同时考虑了决策者风险偏好,更符合实际决策情境。
Quality function deployment(QFD)is a commonly used demand-driven solution design method and tool.To solve the fuzziness and uncertainty of evaluation information in QFD,spherical fuzzy was considered as it has the advantage of independently determining membership degree,nonmembership degree and hesitation degree.Spherical fuzzy numbers were used to process expert semantic evaluation information,and the needs of suppliers and customers were mapped to engineering characteristics.To address the information loss problem due to inverse fuzzification in the existing fuzzy QFD analysis and the failure to consider the psychological preferences of decision makers,TODIM(Portuguese acronym for interactive multi-criteria decision-making)method was adopted to consider the psychological preferences of experts for risk avoidance and perform their importance analysis by calculating the overall dominance of engineering characteristics.In order to verify the effectiveness of the method,an electric vehicle product service system was used as an example to conduct the importance analysis of engineering characteristics,sensitivity analysis of loss avoidance coefficient,and to compare the results of ranking engineering characteristics of different multi-attribute decision methods.The results show that the proposed method can deal with the ambiguity and uncertainty of evaluation information,while taking into account of the risk preferences of decision makers,and is more consistent with the actual decision context.
