Abstract

In this study Data Envelopment Analysis (DEA) is applied to sample banking data when the data is fuzzified. In market conditions, due to some reasons, data is not always obvious and specific. Herewith, it is focused on the fuzziness caused by the diversification of goods and services; examines the applicability of a-cut approach and investigates the optimistic and pessimistic case of DEA from customers' and firms' perspective. Then, an application scheme is proposed when the number of options is excessive for classical methods.
