Abstract: The purpose of the paper is to evaluate the efficiency of the banks using fuzzy extended data envelopment analysis (DEA). One of the limitations of conventional DEA is that it cannot assess efficiency in case of imprecise data. Fuzzy DEA can evaluate efficiency with imprecise data as it takes into consideration the fuzzy characteristics of inputs and outputs. In this paper, variation in inputs and outputs of banks is incorporated in the analysis using fuzzy DEA. Ten reputed Indian commercial banks have been considered to compare the results obtained from conventional DEA and fuzzy DEA. Authors have used a fuzzy ranking method to rank the efficiency of banks, which allows working with the concept of feasibility degree. This research paper may be helpful to managers in analysing the relative efficiency of the bank considering the variation in inputs and outputs during an evaluation period.
