摘要
突发事件频发与当前复杂国际环境的多变凸显了供应商韧性能力评价在提升产业链供应链安全稳定水平中的重要作用.鉴于此,文章以区间直觉模糊信息环境下的供应商韧性评价问题为研究对象,提出了考虑决策者风险偏好的一致性准则权重和专家权重确定方法.首先,根据实际评估值与赋予准则或专家权重后的评估值之间的最大偏差构建非一致性指标,继而通过最小化指标建立Min-Max准则权重优化模型和专家权重优化模型;同时,在模型中引入了风险偏好系数处理行业异质性导致的风险偏好差别;并将专家分类结果引入专家权重优化模型,以刻画同类专家之间的关联;设计了改进的三项共轭梯度算法对权重优化模型进行求解;最后,通过供应商韧性能力评价的算例验证了方法的合理性和有效性,对企业管理实践和群决策理论中权重确定方法起到了一定的补充作用.
The frequent occurrence of emergencies and the current complex international environment have highlighted the important role of supplier resilience evaluation in improving the security and stability of industrial supply chains.In view of this,this paper takes the supplier resilience evaluation problem under the environment of interval-valued intuitionistic fuzzy information as the research object,and proposes the consistent criterion weight and expert weight determination method considering the risk preference of decision makers.Firstly,a non-consistency index is constructed based on the maximum deviation between the actual assessment value and the assessment value after assigning the criterion or expert weights,and then the Min-Max criterion weight optimization model and expert weight optimization model are constructed by minimizing the index;at the same time,a risk preference coefficient is introduced into the model to deal with the differences in risk preferences caused by industry heterogeneity;and the results of the experts'classification are introduced into the expert weight optimization model to depict the correlation between experts of the same type;the three-term conjugate gradient algorithms are designed to solve the weight optimization model;finally,the reasonableness and validity of the method are verified by the example of the evaluation of the toughness of the supplier,and the method is complementary to the enterprise management and the weight determination method of the group decision-making theory.
