具有固定输入DMU的成本效率估计

ESTIMATING ABOUT THE COST EFFICIENCY WITH FIXED DMU INPUT

讨论了评价生产有效性的非参数方法DEA在计算决策单元成本效率中的应用.针对具有固定投入的DEA效率评估模型,本文提出了这类生产系统决策单元的成本效率概念以及测算公式,并结合具体算例对有关定义和模型进行了验证.

The application DEA, a non-parameter method used to evaluate the validity of production, is discussed in this paper. Aimed at the evaluating model of DEA efficiency for fixed investment, the authors proposed an idea of cost efficiency for this system and gave an evaluating formula. The definition and model were verified with some specific examples.
