WEIGHTED INTUITIONISTIC FUZZY DELPHI METHOD

Arindam Garai and Tapan Kumar Roy

This paper presents weighted intuitionistic fuzzy Delphi method. In real life usage of Delphi method, information communicated by experts may not be used with full and complete potential. Hence highly accurate and realistic conclusions cannot always be obtained. In intuitionistic fuzzy Delphi method, communication with experts is the same as fuzzy Delphi method, yet an improved and elaborative statistical tool is used to reach in better conclusions. Again, the experts use their individual competency and subjectivity. And competency and ability to predict successfully varies extensively among experts. Thus different importance and hence weights should be assigned to them by the decision maker. Hence more realistic and accurate prediction is obtained.
