Cloud Provider's Services Evaluation Using Triangular Fuzzy Numbers

Evaluating the available Cloud providers' (CPs) services with respect to multiple, usually conflicting criteria is a complex problem due to the existence of many CPs in the market and to the presence of uncertainty involved in the decision making process. As a solution to the above problem, this paper proposed a fuzzy group decision making multi attribute method based on a combination of fuzzy Simple Additive Weight (SAW) method and maximizing set and minimizing set defuzzification method. The defuzzification method is applied for CPs services ranking. The method is based on triangular fuzzy numbers and aims to aid decision makers (DMs) to evaluate and then rank CPs services. We illustrated the applicability of the fuzzy group decision making multi attribute method using a case study.
