摘要
探讨了先前 DEA研究中所存在的不足 ,如在决策单元的技术效率的测算中 ,投入型与产出型所测算的技术效率在数值上就存在差别 .这不仅会影响对决策单元技术效率的实际分析 ,而且对非有效决策单元的排序也有影响 .本文提出了同时基于投入和产出测算决策单元技术效率的 DEA模型 ,并讨论了模型求解。
This paper examines the existing shortcomings in previous Data Envelopment Analysis ( DEA) studies. In measurements of technical efficiency of Decision Making Units (DMUs), for example, there exists difference between input-based and output-based version in value. As a result, it brings in more difficulties in analyzing actually technical efficiency of a DMU and ranking appropriately DMUs being assessed as inefficient. It suggests another version of DEA for measuring technical efficiency of DMUs based on input and output simultaneously , and then relevant solving approach of model , identification of efficient DMUs and improvement of inefficient DMUs etc. are concerned with in this work.
