基于公平关注的供应链库存管理效率评价研究

Evaluation Research on Supply Chain Inventory Management Efficiency Based on Fairness Concerns

库存协调是供应链管理中至关重要的组成部分,有助于增强供应链的韧性和效率。为解决库存积压、供应链中断等问题,文中通过改进链接控制DEA方法,在其中嵌入Context-dependent,并基于各方利益最大化冲突引入公平关注,构建三方利益协调机制的改进三阶段DEA模型。研究结果表明,对DEA模型进行改进后,整体效率明显提高,各个决策单元(DMU)之间的差距也有所减小;同时,在加入公平关注效用之后,排序更加准确,避免了出现多个DMU效率相等的情况;针对中间库存差异较大的供应链,成功确定了有效的调整措施。

Inventory coordination is a crucial component of supply chain management,helping to enhance the resilience and efficiency of the supply chain.To address issues such as inventory backlog and supply chain disruptions,through improving the link control DEA method,incorporating Context-dependent in it and introducing fairness concerns based on maximizing the interests of all parties,this study constructs an improved three-stage DEA model for three-way benefit coordination mechanism.The research results show that after improving the DEA model,the overall efficiency has significantly increased,and the gaps between decision-making units(DMUs)have also decreased.Furthermore,with the addition of fairness concern utility,the ranking is more accurate,avoiding situations where multiple DMUs have equal efficiency.Effective adjustment measures have been successfully identified for supply chains with significant differences in intermediate inventory.
