基于竞争决策单元的数据包络分析模型

DEA Models Based on Competitive Decision Making Units

决策单元之间处于竞争关系时,所有决策单元的某些投入或产出总和是有限的,一个决策单元改善自身效率的行为可能会影响其他决策单元。针对此情形,提出一种基于竞争决策单元的数据包络分析模型,比较了该模型与传统DEA模型的生产前沿面的区别,并指出此模型在管理决策领域可能的用途。最后,用一个算例分析演示了此模型。

In the case where the DMUs are in competitive relationship,the sums of some inputs or outputs for all DMUs are limited,thus a DMU improves its own performance but probably worsens others.Therefore,this paper proposes a DEA model based on competitive decision making units.The two types of best practice frontiers based on the proposed model and the traditional DEA models are compared.The potential use of this model is also pointed out,and a numeral example is given to demonstrate our approach.
