Abstract ：
非合作情形下,用数据包络分析(data envelopment analysis,DEA)方法对串联系统进行效率评价的研究中,经典的领导者-追随者网络DEA模型(或非合作网络DEA模型)可为系统及其子系统提供唯一的评价结果.但其前提是预先给定系统内部的领导者-追随者顺序.不同的顺序产生不同的评价结果,且并非所有系统均在同一顺序中获得最佳效率.另外,现有网络DEA研究多认为决策者是完全理性的,与现实中决策者有限理性的表现不符.本文针对"非合作情形下无领导者-跟随者顺序时如何评价串联系统及其子系统效率"的问题,基于字典式优化算法和前景理论,提出新的串联系统效率评价方法.该方法可提供唯一的、全面的、可比较的效率评价结果.最后,用14家电力公司数据验证该方法.

Abstract ：
Previous studies on profit improvement mainly consider improving traditional profit efficiency including the technical, allocative, and price profit efficiencies. Few studies discuss profit improvement by optimizing the structural arrangement of the network system, which is about adjusting the combinations of upstream and downstream entities in the system. When achieving traditional efficiency, the system ' s profit can no longer be increased only by reducing inputs, increasing outputs, and adjusting prices. In this situation, structural rearrangement may provide a silver lining to profit improvement. In this study, we take the two -level supply chains as an example and address the research question of how to improve profit via structural rearrangement of the system containing several two -stage subsystems from the efficiency perspective . To answer this question, we view two -stage subsystems in each system as players and propose a data envelopment analysis permutation game method. Through this method, we find the optimal structural rearrangement plan, which is a new way to further improve the profit in addition to improving traditional profit efficiency. We propose a new efficiency measurement, the structural profit efficiency, and find overall profit efficiency is the product of structural profit efficiency and traditional profit efficiency. Finally, we conduct an experiment using the data of 27 supply chains to validate our proposed method and provide the optimal structural rearrangement plans for them.
