Abstract

Due to giganitic size of some websites and their complex structures, prioritizing the various structures turns to be a decision making problem incorporating large uncertainty in judgment, Finding a reponse to such a need, the Fuzzy TOPSIS method, a compbination of the TOPSIS method and Fuzzy theory, could heal some of shortcomings of uncertainties in decision making. However there are still lots of occastions in which decision making is faced with lots of uncertainties making the Fuzzy TOPSIS method not adequately responsive. As a sensible response to this drawback, in this paper, we utilize a brand-new adequately responsive. As a sesible response to this drawback, in this paper, we utilize a brand-new extension of TOPSIS and Fuzzy TOPSIS methods, called Interval Valued Fuzzy TOPSIS with ability to cope with type-2 fuzzy environment and data incorporating much more vagueness in decision making.
