| 摘 要： | 针对经典区间数据包络分析(data envelopment analysis,DEA)求解算法过分依赖于评价者的"主观判别",或求得的效率区间长度可能过大,对被评价决策单元有效性的解释力弱的缺陷,提出一种改进的区间DEA模型求解算法——区间定位法,该方法对评价者的"主观判别"依赖程度低,且求解的效率区间长度较小。在区间定位法的基础上,进一步提出了基于灰色关联度的决策单元效率排序方法。

| Abstract: | The classical algorithm of solving interval DEA models depends much on evaluator’s "subjective discrimination",and has also some shortages,e.g.the efficiency interval length might be too long to evaluate the effectiveness of decision-making unit well if the range of the input and output variables interval is large.Aimming to the advantages and disadvantages of both methods,an improved method,named interval-oriented method,is presented to solve DEA model with interval data.The result of the new method depends less on evaluator’s "subjective discrimination",and its length is shorter.Furthermore,a way to rank decision-making units based on the grey incidence degree is given. |
