【摘要】 针对现有的区间DEA方法采用非统一指标数据进行效率评价的不足,本文在分析现有区间DEA方法的基础上,提出一种基于整体效率的区间DEA方法。该方法能够在多决策单元系统整体效率最大化的同时,得到统一的各决策单元投入/产出的精确数据及各指标权重,一次性求解出所有决策单元的效率。最后,采用一个算例分析说明文章所提方法的合理性和优越性。更多还原

【Abstract】 To overcome deficiencies using non-uniform inputs/outputs data to evaluate the efficiency of existing interval DEA methods,this paper presents an interval DEA method based on overall efficiency.The method optimizes the system efficiency,determines the accurate data of interval inputs/outputs and solves all DMUs’ efficiency.A numerical example is employed to illustrate the effectiveness and superiority of the proposed method.更多还原
