摘要
从云服务提供商角度出发,为提高服务选择的有效性,首先对服务选择流程进行分析,提出面向云服务提供商的服务选择思路,设计服务选择具体流程。进而从服务提供商角度出发,分析影响服务选择结果的主要因素,建立基于用户需求偏好和服务资源调度的服务选择数学模型,设计智能算法进行求解。最后进行算例分析,实验结果验证了该方法的可行性和有效性。
In order to select services more accurately,firstly,a detailed process for services selection was proposed from the perspective of cloud services providers.Secondly,a services selection mathematical programming model was pro-posed for the selection of cloud services by considering two kinds of factors: QoS attributes and services scheduling re-lated parameters,and the model was solved by the GA-based algorithm.Finally,a case study is conducted to demonstrate the feasibility and effectiveness of the proposed approach.
