【摘要】：針對(duì)DEA評(píng)價(jià)與排序時(shí)單獨(dú)采用相對(duì)最優(yōu)效率模型與相對(duì)最差效率模型,存在丟失重要信息的不足,引入DEA模型區(qū)間效率的概念,把兩種評(píng)價(jià)模型有機(jī)結(jié)合,可實(shí)現(xiàn)對(duì)決策單元更合理的評(píng)價(jià)與排序。進(jìn)一步改進(jìn)了DEA區(qū)間效率模型,并對(duì)其計(jì)算效果進(jìn)行分析,找出了計(jì)算決策單元區(qū)間效率的合理模型。在此基礎(chǔ)上引入決策者的偏好系數(shù)β來計(jì)算區(qū)間效率的評(píng)價(jià)指標(biāo),分析得出當(dāng)0≤β≤0.5時(shí)采用相對(duì)最差效率模型,0.5≤β≤1時(shí)采用相對(duì)最優(yōu)效率模型來計(jì)算區(qū)間效率這一結(jié)論。通過具體的數(shù)值算例,對(duì)決策者偏好不同的情況下決策單元區(qū)間效率的評(píng)價(jià)指標(biāo)進(jìn)行計(jì)算和敏感性分析,計(jì)算結(jié)果表明,改進(jìn)的DEA區(qū)間效率模型對(duì)決策單元排序更為合理。
[Abstract]:In order to solve the problem that the relative optimal efficiency model and the relative worst efficiency model are used separately in the evaluation and ranking of DEA, the concept of interval efficiency of DEA model is introduced, and the two evaluation models are combined organically. A more reasonable evaluation and ranking of the decision making unit can be realized. The interval efficiency model of DEA is further improved, and its calculation effect is analyzed, and a reasonable model for calculating interval efficiency of decision making unit is found out. On this basis, the decision maker's preference coefficient 尾 is introduced to calculate the evaluation index of interval efficiency, and the relative worst efficiency model is obtained when 0 鈮，
