We generalize linguistic evaluation values and their weights in group decision-making
(GDM) problems based on unbalanced linguistic terms. The GDM problems include two …

Universal design (UD) is an approach for develo** products and environments that are

In multiobjective optimization problems, the identified Pareto Frontiers and Sets often
contain too many solutions, which make it difficult for the decision maker to select a preferred …

This paper deals with linguistic models that may prove useful for representing the
information during decision making. Data extraction is a complex problem, especially when …

Abstract Information fusion and hesitant information fusion represent an important part of
decision making processes. This paper focuses on hesitant expressions and the way to take …

Computing has reached the time of distributed applications everywhere. Service-oriented
architectures are more and more used to organize such complex and highly dynamic …

This paper will demonstrate a strong relationship between the Compromise Programming
(CP) method and the Ordered Weighted Averaging (OWA) operator. We will mathematically …

Several types of sets, such as hesitant fuzzy sets, permit to express hesitation, doubt, or
perplexity during, eg, a decision‐making process. In this paper, we start giving thought to the …
