ABSTRACT: Cloud provider (CP) selection problem is a complex decision-making problem that involves multiple criteria, often in conflict with one another. The purpose of the paper is to present a brief survey on CP selection problem and to formulate a group decision approach and a multi-objective model for CP selection. Starting from this model several single-objective models are derived. The objective functions are cost, evaluation risk and performance. A numerical example for the trade-off model is analyzed. Five scenarios are discussed, and a matrix of CPs ranks for each scenario is computed.KEYWORDS: Cloud computing, evaluation divergence, evaluation risk, group decision, multi-objective model, provider selectionRead full text (pdf)
