用于供应商风险评价的FMEA改进
|
摘要
提出一种基于犹豫模糊集和灰色关联理论的改进失效模式与后果分析(FMEA)方法用于供应商风险评价.首先对供应商潜在风险进行识别并由专家小组根据偏好使用语义术语对各种风险做出评价,然后采用犹豫模糊集和语义计算的方法处理评价信息,运用粗糙集思想将处理后的信息转化为区间数形式,最后综合考虑各变量的相对重要程度并结合灰色关联理论决定风险排序.以某制造企业的供应商风险评价问题为例,表明所提方法有助于企业识别出合作供应商的主要风险,可以为企业制定风险管控策略提供支持.
This paper proposes an improved failure mode and effects analysis(FMEA)method based on hesitant fuzzy sets and grey relational theory for supplier risk assessment.First,the potential risks of suppliers were identified and then experts evaluated these risks using hesitation fuzzy linguistic terms on the basis of their preferences. Next,the sematic-based computation method and the rough set idea were used to translate the assessment information into interval-valued numbers.Finally,it considered the relative importance of O,S,D when using grey relational theory to determine the risk priority.The case study shows that the method could help companies identify the main risks of cooperating suppliers,as well as provide support for managers to formulate risk management and control strategies.
