“…Note that model (2) In general, weight restrictions may lead to the infeasibility of DEA models (Dyson et al 2001;Sarrico and Dyson, 2004;Podinovski;2004a, 2004bSaati et al 2012;Toloo 2014a -Chameeva (2013) showed that the problem of infeasibility is only one of several possible problems that may occur in the presence of weight restrictions. The authors illustrated that the use of weight restrictions may lead to zero or negative efficiency scores of some operating units in which the production set with trade-offs involves free and/or unlimited production.…”

“…Liu and Peng [39] proposed a method to solve CSW problem and rank DMUs by it. Saati et al [47] presented a two phase CSW approach by using an ideal unit. Ramn et al [45] proposed a method to obtain the common set of weights and then used it for ranking DMUs.…”

“…Now, we review some other works in the field of common weights methodology. Saati et al [27] persented a two-phase algorithm. In the first step, they defined an ideal DMU (IDMU) which was a hypothetical DMU consuming the least inputs to secure the most outputs.…”
