In this paper, the proposed approach in Jiménez et al. [1] is modified and applied to data envelopment analysis (DEA) with consideration of the decision maker (DM)’s preference structures in the fuzzy environment. Consequently, an interactive method resolution is proposed to measure the efficiencies of decision making units (DMUs) in DEA with fuzzy data (input-output). The resulting procedure is called interactive fuzzy data envelopment analysis (IFDEA). The preference information of DM is incorporated in the proposed method reasonably and straightly. An example is employed to illustrate the merit of our approach.
