摘要
针对C2R模型下决策单元在输入和输出的不对称性以及新的线性等价形式在对偶理论上的不足,引进了C2R新线性等价形式的对称模型,并论证了该模型的合理性。证明了对称模型下决策单元DEA有效的等价性定理,因此对称模型是C2R模型的改进。
This note introduces a symmetric models for the unsymmetric problems of new linear equivalent form of C^2R models and the shortcomings of new linear equivalent form of C^2R models in dual theory, and shows that the symmetric models of C^2R is reasonahle. The equivalent theorem of DEA efficiency for decision making units under the symmetric models is proposed. So, the symmetrie models improves C^2R models, and has greater value in theory and application.
