[ 1 ] - Ranking of decision making units based on cross efficiency by undesirable outputs and uncertainity
Cross efficiency is one of the useful methods for ranking of decision making units (DMUs) in data envelopment analysis (DEA). Since the optimal solutions of inputs and outputs weights are not unique so the selection of them are not simple and the ranks of DMUs can be changed by the difference weights. Thus, in this paper, we introduce a method for ranking of DMUs which does not have a unique pr...
[ 2 ] - Measuring robust overall profit efficiency with uncertainty in input and output price vectors
The classic overall profit needs precise information of inputs, outputs, inputs and outputs price vectors. In real word, all data are not certain. Therefore, in this case, stochastic and fuzzy methods use for measuring overall profit efficiency. These methods require more information about the data such as probability distribution function or data membership function, which in some cases may no...
[ 3 ] - رتبه بندی و تحلیل حساسیت رتبه های واحدهای تصمیم گیرنده در تحلیل پوششی داده ها بر مبنای ابرصفحه ایده آل
There are many methods for ranking of DMUs. Some of the previous proposed methods may be infeasible and the others cannot rank all DMUs. In this paper,we introduce a new method for ranking of DMUs that is always feasible and can be usd all ranking of all DMUs. the rank of DMUs is acheived based on the ideal hyperplan. The sensitivity of the rank is presented as well. Therefore, in this study, a...
