A new DEA ranking system based on changing the reference set

A Ranking Method of Extreme Efficient DMUs Using Super-Efficiency Model

“…As reported in Table 3, 15 is the most efficient one in our method and other methods. According to the results, the rankings of DMUs by the four methods are almost similar; in particular, the results of our method are more similar to the method [4].…”

“…Ying-Ming Wang et al [10] proposed a ranking methodology for DMUs by imposing an appropriate minimum weight restriction on all inputs and outputs, which is decided by a decision maker (DM) or an assessor in terms of the solutions to a series of linear programming (LP) models that are specially constructed to determine a maximin weight for each DEA efficient unit. Jahanshahloo et al [4] proposed a ranking system based on changing reference set. in the proposed ranking system, the evaluation for efficient DMUs is dependent of the efficiency changes of all inefficient units due to its absence in the reference set while the estimate for inefficient DMUs depends on the influence of the exclusion of each efficient unit from the reference set.…”

Ranking decision making units by imposing a minimum weight restriction in the data envelopment analysis

“…Jahanshahloo et al [12] proposed a ranking system to rank DEA efficient units in terms of their influences on DEA inefficient units. The influence of a DEA efficient unit on DEA inefficient units is measured by the efficiency change of DEA inefficient units before and after the DEA efficient unit is excluded from their reference set.…”

A Review of Ranking Models in Data Envelopment Analysis

“…Thus, the authors used slackadjusted DEA model and OERA to overcome this difficulty. Jahanshahloo et al [50] presented a new model for ranking DMUs based on alteration in reference set. The idea is based on this fact that efficient units can be the target unit for inefficient units …”

“…Hosseinzadeh Lotfi et al [28] used a new method for ranking in order to find the best place for power plant location. Ali and Nakosteen [79], Amirteimoori et al [37] and Alirezaee and Afsharian [24], Soltanifar and Hosseinzadeh Lotfi [104], Zerafat Angiz et al [71], Hosseinzadeh Lotfi et al [28], Jahanshahloo [50], Chen and Deng [52], and Jablonsky [61] used different ranking methods in banking system. Sadjadi [40] ranked provincial gas companies in Iran.…”
