1Provided a subjective ordinal preference ranking by developing common weights through a series of bounded DEA runs, by closing the gap between the upper and lower limits of the weights.Cook and Kress [19, 20]1990, 1991

2Used a general unbounded DEA model to obtain different sets of weights and then taking their average or weighted average with DEA efficiencies as the weights, maximizing the average efficiency of DMUs, maximizing the number of DEA efficient units, and ranking various factors by some order of importance and then assigning low weights to less important factors and maximal feasible weights to important onesRoll et al.

3Considered the common weights for all the units, by maximizing the sum of efficiency ratios of all the units, in order to rank each unit as well as suggesting a potential use of the common weights for ranking DMUs.Ganley and Cubbin [23]1992

4Developed a two-stage linear discriminate analysis approach to generate the common weightsSinuany-Stern, et al. [24]1994

5Developed a maxi-min efficiency ratio model which also creates common weights for evaluationTroutt [25]1995

6Used the canonical correlation analysis to provide a single weight vector for inputs and outputs, respectively, common to all DMUs.Friedman and Sinuany-Stern [26]1997

7Presented a nonlinear discriminate analysis to provide the common weights for all DMUs.Sinuany-Stern and Friedman [27]1998

8Presented the multiple objectives max-min model to determine CSWChiang and Tzeng [28]2000

9Minimizes a convex combination of these deviations measured in terms of a couple of distances in such familyDespotis [29]2002

10Proposed a DEA-CP (compromise programming) model which aims at seeking a common set of weights across the DMUs by combining the DEA and the compromise programming.Hashimoto and Wu [30]2004

11Based on multiple objective nonlinear programming and by using compromise solution approach, proposed a method to generate a common set of weights for all DMUs which are able to produce a vector of efficiency scores closest to the efficiency scores calculated from the standard DEA model (ideal solution)Kao and Hung [31]2005

12Based on multiple objective nonlinear programming and maximization of the minimum value of the efficiency scores, proposed a method to generate a common set of weights for all DMUs.Jahanshahloo et al. [32]2005

13Developed a goal-programming model for this setting that seeks to derive such a common-multiplier set. The important feature of this multiplier set is that it minimizes the maximum discrepancy among the within-group scores from their ideal levels. And deal with these distances but relax the objective to groups of DMUs which operate in similar circumstancesCook and Zhu [33]2007

14Used a multiple objective linear programming (MOLP) approach for generating a common set of weights in the DEA framework.Makui et al. [34]2008

15Proposed a common weights analysis (CWA) methodology to search for a common set of weights for DMUs.Liu and Peng [18]2008

16Dealt with deviations regarding the total input virtual and the total output virtualFranklin Liu and Peng [35]2009

17Introduced a minimum weight restriction and as a side effect, common weights are also achieved. Imposed weight restrictions to incorporate value judgment are widely researched within DEA but as these methods originally do not necessarily and purposefully provide a full ranking, they are not explicitly discussed here.Wang et al. [36]2009

18Proposed two approaches to obtain the set of common weights for ranking efficient DMUs by comparing with an ideal line and the special line.Jahanshahloo et al. [6]2010

19Proposed a CSW as the average of the profiles of weights provided by the so-called ‘‘neutral’’ model used in the cross-efficiency evaluation.Wang and Chin [37]2010

20Proposed a common weight MCDA-DEA method with a more discriminating power over the existing ones that enable us to construct CIs using a set of common weights.Hatefi and Torabi [38]2010

21Used methods based on regression analysis to seek a common set of weights that are easy to estimate and can produce a full ranking for DMUs.Wang et al. [39]2011

22A separation method is proposed for locating a set of weights, also known as a common set of weights (CSW), in the data envelopment analysis (DEA).Chiang et al. [40]2011

23Extended a common-weights DEA approach involving a linear programming problem to gauge the efficiency of the DMUs with respect to the multiobjective model.Davoodi and Rezai. [41]2012

24Used an approach to minimize the deviations of the CSW from the DEA profiles of weights without zeros of the efficient DMUs. This minimization reduces, in particular, the differences between the DEA profiles of weights that are chosen, so the CSW proposed is a representative summary of such DEA weights profiles. Several norms to the measurement of such differences are used.Ramón et al. [8]2012

25Proposed two models considering ideal and anti-ideal DMU to generate common weights from the view of multiple criteria decision analysis (MADA), for performance evaluation and ranking.Sun et al. [42]2013
