Performance evaluation of DMUs using hybrid fuzzy multi-objective data envelopment analysis

Abstract

The objective of this paper is to evaluate the performance of decision-making units (DMUs) using a hybrid fuzzy multi-objective (FMO) data envelopment analysis (DEA) approach. This study develops fuzzy multi-objective optimistic (FMOO) and pessimistic (FMOP) DEA models for performance evaluation of DMUs. To rank the DMUs, a ranking approach is used that can simultaneously integrate optimistic and pessimistic efficiencies. A comparison of the proposed approach with the existing approach is made with the help of an example. Finally, a real-life application of developed fuzzy optimistic and pessimistic DEA models in the education sector is presented.
