In this paper it has been tried to present a model by usingsome changes in the classical DEA models and combining these modelswith fuzzy models to eliminate these caruso rhodiola weaknesses.Inputs and outputs arerecognized by using MCDM and AHP techniques and experts views.Inthe next step, the gathered data is compounded by fuzzy techniques andentered in the special DEA model after changing to the crisp amounts.Solving DEA model and attaining common set of weights will ealisboa.com helpillustrate the efficient and inefficient units.

As an illustrative case study,the present research applies the proposed approach to evaluate theefficiencies of 18 regional management units of Fars Power DistributionCompany in the year 1384 (2005).Finally, some areas are also suggestedfor further research to be undertaken in future.
