DEA-R MODEL AT PRESENCE FLEXIBLE VARIABLE

Data envelopment analysis (DEA) and ratio analysis (RA) are two widely used methods for measuring units productivity and any other criteria that could be assessed based on the available input and output data. An important linkage between DEA and RA theory is equivalent to the DEA-R models. This model have more freedom in selecting weights in compared with traditional DEA models. In conventional DEA it is assumed that the status of each measure is clearly know as either input or output. However in some situations the performance measure can play either input or output roles. Cook and Zhu (2007) refereed to these data as flexible measure. In this paper we proposed a new evaluation efficiency DEA-R model at presence flexible data.
