Fuzzy Data Envelopment Regression Analysis

The data envelopment analysis (DEA) is favored to evaluate the relative efficiency of public or private firms. The original DEA formulation reveals the relationship with the regression analysis (RA). Thus, this paper presents an integration model for the DEA and fuzzy RA - this analysis technique is named the fuzzy data envelopment regression analysis (FDERA). This new idea is an interesting multi-objective programming aspect. This FDERA model is free of statistical limitations by integrating the fuzzy regression and the DEA model. A simple example is used to show how this new idea works.
