“…The basic DEA models are the CCR model proposed by Charnes et al [24] and the model of Banker et al [25] The FCCR model (3.3) takes the form of fuzzy linear programming problems. Fuzzy set theory is used as alternative to treat the imprecision and the vagueness in DEA models.…”

The banking sector is of great importance to Tunisian's economy. Major commercial banks continue to spend high proportion of their budgets on new technologies and innovation in order to satisfy their customers and enhance their competitiveness. Consequently, performance analysis has become part of their management practices.This paper aims to evaluate the efficiency of commercial Tunisian banks in terms of several crisp and imprecise data. Two approaches of fuzzy data envelopment analysis (FDEA), the possibility approach and the approach based on relations between fuzzy numbers (BRONF), are used to obtain the efficiency score of each bank. The results show that, in a competitive environment, no-financial inputs and outputs should be taken into account in order to obtain credible and realistic efficiency scores.

“…The outputoriented model assumes a fixed level of inputs and maximizes the level of outputs with respect to the given inputs. This model is usually called CCR by authors Charnes, Cooper and Rhodes (Charnes et al, 1978). These models could be used for constant returns to scale.…”

Abstract:The goal of the paper is to evaluate the economic efficiency of tour operators in the Czech Republic in the period 2007-2014 using data envelopment analysis (DEA) models and prove the link between economic efficiency and profitability and to find out if profitability is a good proxy for economic efficiency. Data was exported from the database Albertina CZ Gold Edition. We calculated the efficiency score using CCR (Charnes, Cooper and Rhodes) and BCC (Banker, Charnes and Cooper) models based on 3 inputs and 1 output. In the years 2007 to 2010, the efficiency score of almost all the companies was higher than 0.5; however, in years since 2011, we revealed significant differences in the efficiency of individual firms and only about 40 percent of tour operators achieved an efficiency score higher than 0.5. Using Pearson and Spearman correlation coefficients, our findings show that, in the case of the Czech tour operator market, profitability ratios do not correspond with firm efficiency. Profitability ratios are not a good proxy for economic efficiency and should not be used as the only firm criterion of performance.

“…Since then, an operations research/management science (OR/MS) tool, Data Envelopment Analysis (DEA), was developed as a mathematical programming application to assess the technical efficiency of decision making units (DMU) or organizations [18] . DEA is non-parametric, deterministic non-linear programming technique which is used to define the relative efficiency of each decision-making unit in a sample of comparable DMUs.…”
