研究了只有输出(入)的DEA分析方法,针对只有输出(入)DEA模型的不足,重新定义了只有输出(入)的DEA评价方法的有效性,并改进了模型。相对已有的只有输出(入)的DEA模型,该模型充分利用了决策单元的诸输出(入),提高了DEA评价的效果。作为应用,运用新模型对武警防暴队形优选问题进行了有效性分析。
A DEA analytical method with only output(only input) is studied in the paper.The efficiency of DEA with only output(only input) assessment method is defined.And an improved DEA model with only output(only input) is established.In contrast with the former DEA model,the new model makes the use of outputs(inputs) of the decision-making unit sufficiently and improves the result of DEA assessment.As applications,the efficiency of optimum selection about riot squad formation is studied.
