An algorithm widely used in hotel companies for demand analysis is the so-called K-means. The aforementioned based on use of Euclidean distance as a dissimilarity measure and this fact can cause main handicap. Concretely, provides global difference between values descriptive variables that blur relative differences each component separately and, hence, cluster assign custom to an incorrect clus...

A summary on the symbolic basic arithmetic operators and aggre-gation operators of linguistic information developed by the authors is presented. In particular, label addition, label diierence, product of a label by a positive real number, and convex combination of labels are shown as the symbolic basic arithmetic operators, and two aggregation operators of linguistic information built using tho...

This paper explores the use of the optimization procedures in SAS/OR software with application to the ordered weighted averaging (OWA) operators of decision-making. OWA was originally introduced by Yager (1988) has gained much interest among researchers, hence many applications in the areas of decision making, expert systems, data mining, approximate reasoning, fuzzy system and control have bee...

Prior weights are necessary for the application of ordered weighted averaging (OWA) operators, but obtaining them is expensive and contentious, which restricts operators. To address weighting issue, weight space used to “replace” conventional vector, operator comparison then extended a partial order on space. The results show that OWA can be as long clear, is, there no need take accurate values...

Hybrid offshore wind–solar PV power plants have attracted much attention in recent years due to its advantages of saving land resources, high energy efficiency, generation and stable output. However, the project still being infancy, investors will face a series risks. Hence, multi-criteria group decision-making framework for hybrid risk assessment is constructed this paper. Firstly, 19 indicato...

Several choice processes of alternatives for non-homogeneous group decision making problems, assuming linguistic preference relations for expressing the opinions of individuals and linguistic values for expressing their respective power or importance degrees, are presented. These processes are designed using two choice degrees of alternatives based on the concept of fuzzy majority: quanti-er gu...
