主客观权重和模糊熵相结合的云服务选择方法研究
Cloud Service Selection Method Using Subjective and Objective Weights and Fuzzy Entropy
摘要
Abstract
Cloud service selection is one of the key link for users to use a cloud service.For the problem that the weights are calculated subjectively by using analytic hierarchy process and fuzzy method is improperly used in the process of cloud service selection, the paper puts forward a kind of cloud service selection method which combines subjective and objective weights and fuzzy entropy to solve the problem of cloud service selection.The method uses the analytic hierarchy process to obtain the subjective weights of user and uses the entropy method to obtain the objective weights of service solution.And then the subjective and objective weights are combined to produce the comprehensive weights.Next, the comprehensive weights and the corresponding QoS value are utilized to construct the membership function so as to calculate the correlation coefficient of fuzzy entropy.Finally the service solutions are ordered the coefficient to get the best solution.Experimental results show that the method can more accurately choose a cloud service for the user.关键词
