A novel approach to multi attribute group decision making based on trapezoidal interval type-2 fuzzy soft sets

MULTI-ATTRIBUTE DECISION MAKING METHOD BASED ON BONFERRONI MEAN OPERATOR and possibility degree OF INTERVAL TYPE-2 TRAPEZOIDAL FUZZY SETS

This paper proposes a new approach based on Bonferroni mean operator and possibility degree to solve fuzzy multi-attribute decision making (FMADM) problems in which the attribute value takes the form of interval type-2 fuzzy numbers. We introduce the concepts of interval possibility mean value and present a new method for calculating the possibility degree of two interval trapezoidal type-2 fuz...

Fuzzy Multi-Attribute Group Decision Making Method Based on Interval Type-2 Fuzzy Sets and Applications to Global Supplier Selection

Interval type-2 fuzzy sets (IT2 FS) provide us with additional degrees of freedom to represent the uncertainty and the fuzziness of the real word than traditional type-1 fuzzy sets. In this paper, we investigate the fuzzy multi-attribute group decision making (FMAGDM) problems in which all the information provided by the decision makers (DMs) is expressed as IT2 FS, and the information about at...

An extended MABAC for multi-attribute decision making using trapezoidal interval type-2 fuzzy numbers

The purpose of this paper is to study a type-2 fuzzy multi-attribute decision making (MADM) methodology. Multi-Attributive Border Approximation area Comparison (MABAC) method is extended for MADM based on trapezoidal interval type-2 fuzzy numbers (TrIT2FNs).This method is a pragmatic and reliable tool for rational decision making due to its own characteristics. A systematic evaluation and asses...

Interval-valued trapezoidal intuitionistic fuzzy generalized aggregation operators and application to multi-attribute group decision making

Group Generalized Interval-valued Intuitionistic Fuzzy Soft Sets and Their Applications in\ Decision Making

Interval-valued intuitionistic fuzzy sets (IVIFSs) are widely used to handle uncertainty and imprecision in decision making. However, in more complicated environment, it is difficult to express the uncertain information by an IVIFS with considering the decision-making preference. Hence, this paper proposes a group generalized interval-valued intuitionistic fuzzy soft set (G-GIVIFSS) which conta...
