Abstract :
< p>In this paper, first the DEA-RA (integration of DEA with Ratio Analysis) output and input oriented is proposed. Then, by using the fully fuzzy problem and the problem that only the parameters are fuzzy, the DEA-RA joint model has been proposed. Therefore the lexicographic approach and the α-cut approach have been used for these two types of the problems and evaluation of research projects. DEA-RA models behave similarly to DEA models. In this study, the input and output parameters are not ratio, but if the input to output ratios and vice versa are defined, DEA-RA models can also be a criterion for calculating the efficiency and evaluation of units.
