A fuzzy expected value approach under generalized data envelopment analysis
Fuzzy data envelopment analysis (DEA) models emerge as another class of DEA models to account for imprecise inputs and outputs for decision making units (DMUs). Although several approaches for solving fuzzy DEA models have ...
A Fully Fuzzified Two-stage DEA
There is a growing literature in DEA where researchers are opening the black box to evaluate the efficiency performance of internal processes. Within this context, we study a relational two-stage DEA model where there is ...
Carbon efficiency evaluation: An analytical framework using fuzzy DEA
Data Envelopment Analysis (DEA) is a powerful analytical technique for measuring the relative efficiency of alternatives based on their inputs and outputs. The alternatives can be in the form of countries who attempt to ...
