A mathematical approach to solve data envelopment analysis models when data are LR fuzzy numbers
Data envelopment analysis fuzzy mathematical programming
2010/9/15
data envelopment analysis is a linear programming methodologie that has been widely used to evaluate the performance of a set of decision-making units. It requires crisp input and output data. However...
A centroid-based performance evaluation using aggregated fuzzy numbers
Aggregated fuzzy numbers centroid index
2010/9/15
In recent years, some methods have been proposed in solving performance evaluation issues by using fuzzy set theory. In this paper, an improvised method for performance evaluation under fuzzy environm...

In this paper we give some properties of good and special convergence (introduced
by L. d’Apuzzo in 1977) of the sequence of successive approximations associated
to the Bernstein operators of unifor...
In this paper we introduce double convergent sequences of fuzzy numbers and we also study the space of double convergent sequences of fuzzy numbers.
