Multiple Attribute Group Decision Making Methods Using Intuitionistic Trapezoidal Fuzzy Numbers

Abstract

 Solving Multiple Attribute Group Decision Making (MAGDM) problems has become one of the most important researches in the recent trends. The information or data is in the form of Intuitionistic Trapezoidal Fuzzy Number (ITzFN). The methods are applied in decision making problems. The Intuitionistic Trapezoidal Fuzzy Ordered Weighted Geometric (ITzFOWG) operator and the Intuitionistic Trapezoidal Fuzzy Hybrid Geometric (ITzFHG) operator are used to combine the decision matrix. The correlation coefficient is used for ranking the best alternatives. Numerical illustration is proposed to show the effectiveness of the method.
