【摘要】：在数据包络分析方法的研究中,当决策单元的输入输出值为区间数时,区间效率的测算取决于生产参照集的选择.对此,针对非径向非角度的松弛测度模型(SBM),通过比较计算认为,以最佳生产状态为统一参照来测算决策单元的区间效率最有利于排序.同时,利用区间数相似度理论建立模糊相似矩阵,进而提出基于参照单元区间效率的相似度排序方法,对决策单元聚类和排序.最后通过算例表明了所提出方法的可行性和有效性.
[Abstract]:In the research of data envelopment analysis method, when the input and output value of decision making unit is interval number, the calculation of interval efficiency depends on the selection of production reference set. In view of the relaxation measure model of non-radial non-angle, it is considered that the best production condition is the uniform reference to calculate the interval efficiency of the decision making unit. At the same time, the fuzzy similarity matrix is established by using the theory of interval number similarity, and then a similarity ranking method based on the interval efficiency of reference units is proposed to cluster and sort decision units. Finally, an example is given to show the feasibility and effectiveness of the proposed method.
