摘要
不确定条件下系统相对有效性评价是当前 DEA理论研究的前沿 .本文探讨了决策单元的投入、产出指标数据为区间不确定数时 ,决策单元的相对有效性评价问题 .提出了决策单元区间相对有效的概念和有效性评价的区间 DEA算法 .
The study of efficiency evaluation under uncertainty is highlighted by the vast existence of stochastic or fuzzy factors in the evaluating problem.A general procedure to evaluate the relative efficiency of DMU s with interval inputs and outputs is provided in this paper.The robust input or output regions,in which the evaluated DMU remains efficient are discussed and the efficiency score to measure the efficiency of evaluated DMU is extended.It shows that the new method is very helpful to evaluate the relative efficiency of DMU s under uncertainty.
