【摘要】：当今社会，经济发展迅速，竞争异常激烈。要想实现绩效的最优化成为全社会的共同关注，对效率和收益情况的评估问题也成为首要核心研究。在处处充满竞争和合作关系的社会中，每个环节都存在着系统和子系统的关系。而选择合适的评价模型，对复杂的系统进行评价，也成为一个挑战。随着网络经济时代的到来，在全球的各个领域，也掀起了合作的高潮。但不可否认的是合作在我们的日常生活中起着不可或缺的作用，特别是随着以计算机、网络、通讯技术为依托的网络经济时代的到来，全球更是掀起了合作的高潮。本文通过分析系统内部各个子系统之间的合作关系，针对环形系统内部的运作过程处于循环状态，这一不同于其他网络系统的突出特点，分析其单个动态循环阶段，建立评价单阶段环形生产过程的DEA模型。然后，将其推广到整体循环过程，进行环形生产系统的DEA效率评价，给出此网络决策单元的DEA有效性。并通过分析决策单元间的合作关系，将环形系统DEA理论和合作博弈理论相结合，，把需要作评价的各决策单元（DMU）作为合作博弈的局中人，依据理性假设定义了联盟博弈的特征函数，提出了基于合作博弈的环形系统DEA模型，选择了Shapley值作为该模型的解。最后以京东商城的闭环供应链和外包合作物流模式进行了实例应用。通过环形系统DEA评价模型的构建，一方面，可以为环形系统效率评价提供新的思路和方法，另一方面，将合作博弈应用到环形系统DEA模型中可以解决不同行为偏好DMU间的管理问题，如对利益进行分配，对资源进行合理的配置，并且设定企业经营目标等，为决策提供更有力的依据。
[Abstract]:Nowadays, the economy is developing rapidly and the competition is fierce. In order to optimize the performance of the whole society, the evaluation of efficiency and income has become the most important research. In a society full of competition and cooperation, there is a relationship between system and subsystem in every link. It is also a challenge to select appropriate evaluation models and evaluate complex systems. With the arrival of the network economy era, in all fields of the world, also set off the climax of cooperation. However, it is undeniable that cooperation plays an indispensable role in our daily life, especially with the arrival of the era of network economy based on computer, network and communication technology, the global cooperation is set off a climax. In this paper, by analyzing the cooperative relationship among the subsystems in the system, aiming at the circulating state of the internal operation process of the ring system, which is different from the outstanding characteristics of other network systems, this paper analyzes the single dynamic cycle stage of the ring system. A DEA model was established to evaluate the single stage annular production process. Then, it is extended to the whole cycle process to evaluate the DEA efficiency of the annular production system, and the DEA effectiveness of the network decision making unit is given. By analyzing the cooperative relationship between the decision making units, the DEA theory of ring system and the cooperative game theory are combined, and the decision making units (DMU) which need to be evaluated are regarded as the players in the cooperative game. According to rational hypothesis, the characteristic function of alliance game is defined, and the DEA model of ring system based on cooperative game is proposed. The Shapley value is chosen as the solution of the model. Finally, the closed-loop supply chain and outsourcing cooperative logistics model of JingDong Mall are applied. Through the construction of ring system DEA evaluation model, on the one hand, it can provide new ideas and methods for ring system efficiency evaluation, on the other hand, Applying cooperative game to the DEA model of ring system can solve the management problems between DMU with different behavior preferences, such as the allocation of benefits, the rational allocation of resources, and the setting of business objectives, etc. To provide a more effective basis for decision-making.
