Ambiguous and uncertain facts can be handled using a hesitant 2-tuple linguistic set (H2TLS), an important expansion of the set. The vagueness uncertainty data grabbed by aggregation operators. Therefore, operators play role in computational processes to merge information provided decision makers (DMs). Furthermore, operator is potential mechanism for merging multisource which synonymous with c...

Fuzzy Cognitive Maps (FCM) are a promising approach for socio-ecological systems modelling. FCMs represent problem knowledge extracted from different stakeholders in the form of connected factors/variables with imprecise cause-effect relationships and many feedback loops. These typically large maps are condensed and aggregated to obtain a summary view of the system. However, representation, con...

in this paper we give conditions for a tuple of commutative bounded linear operators which holds in the property of the hypercyclicity criterion. we characterize topological transitivity and semi-hereiditarily of a dynamical system given  by an n-tuple of operators acting on a separable infinite dimensional banach space .

Majorities based on difference of votes and their extension, majorities based on difference in support, were introduced in social choice voting as tools to implement the crisp preference values (votes) and the intensities of preference provided by voters when comparing pairs of alternatives, respectively, with the aim to declare which alternative is socially preferred. Moreover, these rules req...

The segmentation of clients in a specific market is very useful to identify different groups of them that let develop specific marketing policies to better suit the demand and to get a higher market share. This item is specially relevant when a new product or service is launched, in order to focus strategies on most relevant clients, reducing costing and increasing the impact of marketing actio...

abstract: In the last years, participation of suppliers in development, production, and distribution products has increased. this way, sustainability an organization depends more on these partners. The supplier assessment must be based economic, environmental social tripod called triple bottom line (TBL). Due to recent adoption qualitative metrics related issues business management, models that...

In order to comprehensively evaluate the employee satisfaction of mine occupational health and safety management system, an analytic method based on fuzzy analytic hierarchy process and 2-tuple linguistic model was established. Based on the establishment of 5 first-grade indicators and 20 second-grade ones, method of improved AHP and the time-ordered Weighted Averaging Operator (T-OWA) model is...

The theory of grey systems plays an important role in science, engineering and in the everyday life in general for handling approximate data. In the present paper grey numbers are used as a tool for assessing with linguistic expressions the mean performance of a group of objects participating in a certain activity. Two applications to student and football player assessment are also presented il...
