چكيده فارسي :
In many applications of DEA data are ratio. Such as fiscal organization and accounting data. There are different point of view to evaluation the DMUs with ratio data. In DEA-R model we consider the ratio between inputs and outputs as independent indexes. In other word according to the suitable orientation we consider the input / output ratios as inputs in input oriented and output / input ratios as outputs in output oriented. There are many studies about DEA-R which consider the efficiency measure and weights interpretationof it. In this paper we proposed the algorithm to find the strong defining hyperplanes of DEA-R model. This study helps to determination the sensitivity analysis of model.
