Two-Stage Fuzzy Logic Model for Cloud Service Supplier Selection and Evaluation

Abstract EN

Dynamicity of the cloud computing system, complexity of real-world decision-making problems, and nontransparent market imply numerous difficulties in finding the corresponding solution for cloud supplier evaluation and selection.

Due to that reason, there is a need to develop a model that can contribute to increase of reliability of evaluation and reduction of subjectivity of the decision-maker.

Having in mind the aforementioned, the authors proposed a new concept to model a cloud supplier evaluation based on technology perspective.

Here, we developed a model that combined fuzzy techniques with implemented simulation of model parameters.

The proposed method for cloud supplier evaluation is flexible with an objective evaluation and ensures more precise numerical value.

Numerical examples are presented to demonstrate the effectiveness and pragmatism of the proposed approach.
