“…A preference ratio method was used to rank the interval efficiency scores. Other works related to this approach can be found in [39][40][41][42][43][44]. Another popular approach is the possibility approach.…”

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.

“…To this end, experts must provide the most likely value (modal value) of these numbers and their variation interval. We chose triangular fuzzy numbers not only because they are easy to handle and they reflect situations involving uncertainty very well (Zimmermann, 1996;León et al, 2003), but also because they have been successfully used in situations similar to those presented here (Chang and Lee, 2012).…”

Our purpose in this paper is to assist decision-makers in the task of selecting project portfolios to satisfy their requirements and guarantee profitable growth. This task usually involves decision-makers having to face multiple objectives and constraints, as well as the uncertainty associated with certain parameters of the problem. Therefore, in this paper, we propose a multiobjective programming model, which includes uncertainty through the use A multiobjective fuzzy model for selecting and planning a project portfolio 49 of fuzzy parameters and allows us to represent information not fully known by the decision-makers. The resulting model has been applied to a project portfolio selection process in a public organisation.

“…The third drawback in existing fuzzy DEA models is its ability to only cater to either triangular fuzzy numbers (see León, Liern, Ruiz, & Sirvent, 2003) or symmetrical triangular fuzzy numbers (see Guo and Tanaka, 2001).…”
