چکیده
Data Envelopment Analysis (DEA) models can be stated as two mutually dual linear programs referred to as the envelopment and multiplier models. The multiplier models are stated in terms of variable input and output weights (multipliers). Zero multiplier weight for an input or output causes efficient problems in multiplier model. This paper concentrates on a previously proposed DEA model developed by Wang and Chin (2010) and later improved by Wang et al. (2011) to find non-zero multi-plier weights. We will show that these models reveal shortcoming for certain classes of DMUs. In addition, we propose a general developed model to find a maximal element for a multiplier DEA model.
