【摘要】:在數(shù)據(jù)包絡分析方法的研究中,當決策單元的輸入輸出值為區(qū)間數(shù)時,區(qū)間效率的測算取決于生產(chǎn)參照集的選擇.對此,針對非徑向非角度的松弛測度模型(SBM),通過比較計算認為,以最佳生產(chǎn)狀態(tài)為統(tǒng)一參照來測算決策單元的區(qū)間效率最有利于排序.同時,利用區(qū)間數(shù)相似度理論建立模糊相似矩陣,進而提出基于參照單元區(qū)間效率的相似度排序方法,對決策單元聚類和排序.最后通過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.
