ABSTRACT

Performance or efficiency evaluation is of great importance for effective supply chain management, especially in the context of sustainable development and platform economy. In existing literature, two-stage network data envelopment analysis (DEA) has been widely used for supply chain efficiency evaluation. Although existing supply chain DEA usually assumes two-stage systems resolve the inherent conflicts between two stages, e.g. the supplier and manufacturer in a two-echelon supply chain, the relation of supply chain DEA to traditional ‘black box' DEA remains unclear. Moreover, the coordination effect between the two stages is ignored. In this paper, we define the coordination efficiency and propose a DEA-based approach for measuring the coordination effect of supply chain systems. We prove that the proposed multiplier DEA approach is equivalent to the envelopment DEA one. The proposed approach in this paper is verified via a numerical example from a supplier–manufacturer sustainable supply chain on resin companies finally.

摘要

绩效或效率评估对于有效的供应链管理非常重要，尤其是在可持续发展和平台经济的背景下。在现有文献中，两阶段网络数据包络分析（DEA）已被广泛用于供应链效率评估。虽然现有的供应链DEA通常假设两阶段系统解决了两个阶段之间的内在冲突，例如两级供应链中的供应商和制造商，但供应链DEA与传统“黑匣子”DEA的关系仍不清楚。此外，忽略了两个阶段之间的协调效应。在本文中，我们定义了协调效率，并提出了一种基于 DEA 的方法来衡量供应链系统的协调效果。我们证明了所提出的乘数 DEA 方法等价于包络 DEA 方法。本文提出的方法最终通过树脂公司供应商-制造商可持续供应链的数值示例得到验证。
