灰色群组聚类和改进CRITIC赋权的供应商选择VIKOR多属性决策

针对武器装备供应商选择问题, 提出了一种基于灰色群组(grey group clustering, GGC)和改进标准间冲突性相关性(improved criteria importance through intercriteria correlation, ICRITIC)组合赋权的扩展多属性妥协解(VIKOR)决策方法。采用考虑决策专家意见差异程度的群层次分析法对供应商初选指标体系进行降维遴选, 构建武器装备供应商优选指标体系; 结合GGC和ICRITIC组合赋权方法确定主客观权重, 并设计权偏好系数进行加法组合赋权; 基于VIKOR决策方法集结备选供应商折衷排序值。针对不同折衷系数、排序方法和赋权方法从决策灵活性和稳定性两个维度进行对比分析, 验证所提方法的有效性。

Supplier selection VIKOR multi-attribute decision making of grey group clustering and improved CRITIC weighting

A VIKOR decision making method based on grey group clustering (GGC) and improved criteria importance through intercriteria correlation (ICRITIC) combination weighting is proposed to deal with the problem of weapon equipment supplier selection. The optimization indicator system of weapon equipment supplier selection is constructed by the group analytic hierarchy process method which considers the variation degree of decision makers. Combined with GGC subjective weight and ICRITIC objective weight approach, the weight preference coefficient is proposed to determine the indicator weight by additive combination weighting. The VIKOR decision making method is used to aggregate compromise ranking values of alternative suppliers. The comparison with different compromise coefficients, sorting and weighting approaches from flexibility and stability dimensions verifies the effectiveness of the proposed method.
