Radial models of DEA to measure the efficiency of DMUs assumed an inefficient unit to be efficient must decrease (increase) proportional all inputs (outputs) as the same. This assumption is absolutely false, unnecessary and unrealistic, therefore, to address this deficiency, and raise awareness of how to use resources, it is so realistic that expect the various inputs have different efficiency. Also, due to uncertainty in the human thinking and judgment, and fuzzy DEA models can play an important role for evaluating the performance of the real issues. In this study, to evaluate the performance of the two inputs and two outputs faculty of Tehran University non-radial fuzzy input efficiency Profiling model was used. After solve of 180 models at various cutting level for two inputs efficiency we obtained input efficiency as fuzzy numbers that ranked by method of Chen and Klein, then the complete ranking of colleges with suggested technique FIEP / AHP results in the Faculty of Letters and Humanities and the Faculty of Law and political Science ranked as the first and the last respectively
