基于模糊软集的航空制造企业供应商绩效评估

Research on Supplier Performance Evaluation of Aviation Manufacturing Enterprises Based on Fuzzy Soft Set

航空制造企业是国民经济的支柱产业,其供应商的绩效优劣将直接影响产品的最终质量。针对以往供应商绩效评估模型中参数难以确定的问题,提出了基于模糊软集的供应商绩效评估方法。针对航空制造企业的特点,通过查阅和总结资料建立评估指标体系,采用相对差异函数模型来确定相对差异隶属度,从而构建模糊软集合并对供应商的绩效进行综合评价。为解决指标权重确定过程过于主观的问题,采用基于级差最大化的主客观组合赋权法确定指标权重。最后以C航空制造公司供应商绩效评估为例,验证了所提评估模型的有效性和可行性。

Aviation manufacturing enterprises are the pillar industries of the national economy.The performance of their suppliers will directly affect the final quality of products.Aiming at the problem that parameters are difficult to determine in previous supplier performance evaluation models,a supplier performance evaluation method based on fuzzy soft set is proposed.According to the characteristics of aviation manufacturing enterprises,the evaluation index system is established by consulting and summarizing the data,and the relative difference function model is used to determine the relative difference membership degree,thus the fuzzy soft set is constructed and the supplier′s performance is evaluated comprehensively.In order to solve the problem that the process of determining index weights is too subjective,the subjective and objective combination weighting method based on gradient maximization is used to determine index weights.Finally,an example of supplier performance evaluation of C aviation manufacturing company is given to verify the validity and feasibility of the evaluation model.
