In recent years, q-rung orthopair fuzzy sets (q-ROFSs), a novel and rigorous generalization of the set (FS) coined by Yager in 2017, have been used to manage inexplicit indefinite information daily life with high precision greater accuracy than intuitionistic (IFSs) Pythagorean (PFSs). The characterization measure similarity between q-ROFSs is important, as they applications different areas, in...

The interventions aimed at the early childhood are of a main interest in educational policy, since it is in this period when it is possible to produce a major impact in the subsequent human development. The quality of children’s social environment is the main influence to consider in achieving sound child development, affecting throughout school life. For this reason, the development of child’s...

The OWA operator proposed by Yager has been widely used to aggregate experts’ opinions or preferences in human decision making. Yager’s traditional OWA operator focuses exclusively on the aggregation of crisp numbers. However, experts usually tend to express their opinions or preferences in a very natural way via linguistic terms. These linguistic terms can be modelled or expressed by (type-1) ...

there are two interesting methods, in the literature, for solving fuzzy linear programming problems in which the elements of coefficient matrix of the constraints are represented by real numbers and rest of the parameters are represented by symmetric trapezoidal fuzzy numbers. the first method, named as fuzzy primal simplex method, assumes an initial primal basic feasible solution is at hand. t...

A verbal model is a model that allows for linguistic rather than numerical variables, and for causal relationships between the variables to be formulated verbally rather than mathematically (Wenst0p, 1976). Examples for such include Kickert's model (1979) in which Mulder's theory of power is reformalized verbally, Wenst0p's (1976) deductive verbal models of organizations, and Yager's (1979; 198...

Screening procedures are typically operationalized in GIS by means of Boolean operations using conjunctive or disjunctive decision rules. There are several conceptual and technical problems with the conventional screening methods. The methods require fairly detailed a priori information about the cut-oV values, aspiration (target) levels, or preferences with respect to the relative importance o...

We discuss an approach to fuzzy linguistic summaries of data (bases) in the sense of Yager, i.e., for instance, if we have a (large) database on employees, and we are interested in a relation between the age and qualifications, then it may be summarized by, say, “most young employees are well qualified”. We present the derivation of such linguistic summaries in the context of Zadeh’s computing ...

Recent developments of sensors and computers have raised the problem of handling huge amounts of complex data that users try to synthesize for decision making. Aggregation operators, such as those appearing in fuzzy sets theory, are useful tools for this synthesis but in their present formulation, these operators only deal with a finite set of arguments. In this paper, we introduce G3 , an exte...

Often, about the same real-life system, we have both measurementrelated probabilistic information expressed by a probability measure P (S) and expert-related possibilistic information expressed by a possibility measure M(S). To get the most adequate idea about the system, we must combine these two pieces of information. For this combination, R. Yager – borrowing an idea from fuzzy logic – propo...
