A Hybrid Method for Cloud Quality of Service Criteria Weighting

Abstract

The Multi-Criteria Decision Making (MCDM) methods can be used for selection of a Cloud Services Provider (CSP). The most critical input of these methods is the assignment of criteria weights which can be based on subjective, objective, or a combination of weighting methods. In this paper a new hybrid method is proposed for Quality of Service (QoS) criteria analysis and weighting. The approach is based on a subjective weighting method and an objective weighting method. The hybrid method is applied in a case study. An analysis of causal relations and the degree of influence between QoS criteria based on DEMATEL method is presented.
