- One of the most powerful and applicable tools to evaluate the efficiency of decision making units (DMUs) is data envelopment analysis (DEA). In order to evaluate the efficiency of multi-division DMUs, it is essential to pay attention to the internal or linking activities among their different divisions, and also, we have presented a model of DEA, due to uncertainty in some input and output indexes of units, which beside paying attention to internal or linking activities, the data have been entered into the model in a fuzzy form. The suggested model is a slacks-based measure (SBM) model which deals with evaluating the efficiency of DMUs. At the end, a case study on the Iran regional power companies using the suggested model is presented. Mean whilst the proposed model is compared with other existing models and the results prove its advantages as well as the validity of our model.
