Description

1. Introduction Cloud technologies, which enable new methods for provision of services and products by innovative and technological possibilities, are widely used all around us. Cloud service is a collection of computing; it usually refers to a dynamic and scalable virtualized resource. Te quality of cloud service supplier is an important factor afecting the development of cloud computing. Due to increasing userspecifc requirements for cloud services and diferentiated quality of cloud services from numerous cloud service suppliers, selection of an appropriate cloud service supplier, based on technology, becomes a signifcant challenge for decision-makers. Cloud service supplier uses diferent techniques such as ontologies, languages, standards, and tree structure and there is not a unifed service description that describes all cloud service types, IaaS, PaaS, and SaaS. Apart from that, dynamicity of cloud computing and constant adding of new services and applications additionally make selection of the best cloud service supplier harder under the background of cloud computing emergence. Another problem in evaluation and service supplier selection is selection of a fexible and reliable model that enables fast implementation of new information. Various mathematical techniques have been used by the researchers for selection and evaluation of suppliers. Tere are many evaluation methods in domain of cloud security engineering and cloud services security [1, 2], the quality of service [3–5], cloud storage [6], cloud manufacturing [7], and so on. Multicriteria decision-making (MCDM) allows decision-makers to face complex decision-making situations involving multiple, usually conficting decision criteria, which include quantitative and/or qualitative aspects in a decision-making process. AHP method takes a signifcant place during selection of MCDM techniques for supplier evaluation and selection [8]. Critics of this method indicate that signifcance of elements presents only some sort of arithmetic accuracy that does not refect real or objective evaluation. Also, when judgment matrix is not consistent, the adjustment is ofen with blindness and extensive calculation. Authors ofen combine this and other methods in order to overcome the stated defciencies [9–12] and more can be seen in review paper of Le Sun [13]. In realistic environment of supplier selection and evaluation, a decision-maker must take into account diferent uncertain factors. Fuzzy-logic-based approach and decisionmaking problems under linguistic environment have been widely used in all areas of science and are one of the tools used for supplier selection [14, 15]. Authors are trying to resolve the complexity of supplier selection problem by applying hybrid (integrated) models. Te research of Simic´ [16] presents how fuzzy set theory, fuzzy decision-making, and hybrid solutions based on fuzzy mathematics can be used in the various models for supplier assessment and selection in a 50-year period.
