Methods of Intuitionistic Fuzzy Correlation in Group Decision Making

A Multiple Attribute Group Decision Making (MAGDM) problem is to find a desirable solution from a finite number of feasible alternatives assessed on multiple attributes - quantitative and qualitative. Attaching numerical measures to attributes involved in a MAGDM problem needs a careful study of the problem. There are various techniques available for attaching numerical measures namely the Weighted Averaging (WA) Ordered Weighted Averaging (OWA) Induced-OWA Ordered Weighted Geometric (OWG) Induced-OWG etc. out of which a suitable one should be chosen. New MAGDM algorithms using a variety of these operators are proposed. Correlation Coefficient is used as a tool for ranking different alternatives in the decision making problems. Further Data mining techniques like Association Rules and Correlation Rule Mining are fused into the Decision Making problems to make the ranking process more effective.
