We investigate multiple criteria group decision-making problems in which there are priority relationships between the decision elements (criteria and experts), and decision information provided by decision makers takes the form of multigranular uncertain linguistic information. Firstly, some operational laws and possibility degree of multi-granular uncertain linguistic variables are introduced....

Sugeno integrals are a well-known family of qualitative multiple criteria aggregation operators. The paper investigates how the behavior of these operators can be described in a prioritized propositional logic language, namely possibilistic logic. The case of binary-valued criteria, which amounts to providing a logical description of the fuzzy measure underlying the integral, is first considere...

A generalized form of union and intersection on FFS can be formulated from a t-norm (TN) t-conorm (TCN). Hamacher operations such as product sum are good alternatives to produce sum. The generate more flexible accurate results in decision-making process due the working parameter involved these operations. intuitionistic fuzzy set, briefly IFS its extension involving Pythagorean set (PFS) Fermat...

aggregation operators (aos) have been studied by many schol- ars. as many aos are proposed, there is still lacking approach to classify the categories of ao, and to select the appropriate ao within the ao candidates. in this research, each ao can be regarded as a cognitive style or individual dierence. a cognitive style and aggregation operator (csao) model is pro- posed to analyze the mapping ...

Aggregation operators (AOs) have been studied by many schol- ars. As many AOs are proposed, there is still lacking approach to classify the categories of AO, and to select the appropriate AO within the AO candidates. In this research, each AO can be regarded as a cognitive style or individual dierence. A Cognitive Style and Aggregation Operator (CSAO) model is pro- posed to analyze the mapping ...

To reduce greenhouse gas emissions, conserve the environment, and dependency on fossil fuels, transition from energy to renewable is deemed essential. Several companies around globe, especially big conglomerates, were pioneers in use of energy. For sustainable growth, Pakistani businesses are growing increasingly interested green sources manufacturing economic activities. In recent years, there...
