Aggregation is the process of combining several numerical values into a single
representative value, and an aggregation function performs this operation. These functions …

The ranking of fuzzy numbers has become an important component in the decision process.
Ranking of fuzzy numbers is not an easy task as fuzzy numbers are represented by …

This paper proposed a novel approach to ranking fuzzy numbers based on the left and right
deviation degree (L–R deviation degree). In the approach, the maximal and minimal …

Six-Sigma is a tactical tool of significant value in achieving operational excellence. The
project selection decision, under a resources constraint, is the early stage of implementation …

A total of 17 reinforced concrete footings were tested to investigate the punching shear
behavior of footings. The test parameters investigated are the shear span to depth ratio …

In this paper, we present a new approach for fuzzy risk analysis based on the ranking of
fuzzy numbers. First, we propose a new method for ranking fuzzy numbers using the α-cuts …

Customer evaluation plays an important role as a part of the order acceptance process of
suppliers in optimally allocating resources and prioritizing orders accordingly. In this paper …

The hydrological sciences typically present grey or fuzzy information, making them quite
messy and a choice challenge for fuzzy logic application. Providing readers with the first …

We establish in this paper the link between the two main approaches for fuzzy mathematical
morphology, based on duality with respect to complementation and on the adjunction …

We describe some basic features of the OWA operator. We turn to the problem of
determining the weights associated with this operator and particularly the maximal …
