摘要
在产品制造过程中,关键质量影响因素的识别与分析是质量和工艺人员关注的焦点.目前关键质量影响因素的识别往往依赖于专家经验,而专家评价信息的模糊性和不确定性使得传统方法存在应用局限.因此对基于模糊集理论和VIKOR的产品制造过程质量影响因素识别与分析方法进行研究,将不确定性信息引入评价指标中,并通过对质量影响因素的重要性排序,实现了关键质量影响因素的识别与分析;最后在某航空产品焊接过程上进行了应用,验证了方法的有效性.
Abstract
In most manufacturing processes,identifying the key process factors that may lead to quality issues is crucial for quality engineers and practitioners.There are several evaluating procedures for identifying key factors under exports'experiences.Howev-er,in practice,the fuzziness and uncertainty of evaluation information is rarely considered,which restricts the applicability of such procedures in key factors analysis.Therefore,an uncertainty-driven approach based on fuzzy set theory and VIKOR for key quali-ty-effected factors identification and analysis is proposed,which is efficient for factors'orders of importance.Application results in welding processes of a certain aviation product demonstrate the effective of the proposed procedure.
