摘　　要：越来越多的云服务为消费者提供了广泛的选择,使云服务选择成为一个具有挑战性的决策问题,这需要使用恰当的决策方法,协助决策者选择最好的服务以满足用户的需求.本文提出一个云服务选择方法,给出了云服务的服务质量(Quality of Service,QoS)的描述形式.引入了ELECTRE的排序方法,该方法通过建立一致性矩阵和矛盾性矩阵来获得各个服务的的优先级别关系.最后,通过实例验证了该算法的有效性.The growing number of cloud services has made service selection a challenging decision-making problem by offering wide ranging choices for cloud service consumers. This necessitates the use of appropriate decision making methodologies to assist a decision maker in selecting the service that best fulfills the user＇s requirements. In this paper, we present a cloud service description form of quality of service, and present a cloud service selection methodology. The method of ELECTRE is introduced, which establishes the consistency matrix and the contradiction matrix to obtain the priority relation of each service. Finally,the algorithm is verified by an example.
