基于Qos编排下Web服务的相对权重组合研究

Research on Relative Weight Combination of Web Service Based on Qos

随着Web服务的发展,用户如何在高度复杂的网络环境下选择满足最大Qos(Quality of service)是研究的难点.提出了一种基于Qos编排下Web服务的可信研究,对目标Web服务之间可信度进行度量,初步确定在不同Qos要求下服务间的相对权重,然后通过权重关系选择一条服务路径.根据不同用户对不同Qos的要求形成不同的服务组合形式,构建了不同的服务相对权重.最终能够为不同用户推荐不同的服务组合,以达到比较好的Qos要求.

With the development of Web services, users can choose the best Qos （Quality of service） in the highly complex network environment. This paper presents a credible study based on Qos Coding,which measures the credibility between target Web services, determines the relative weights of services between different Qos requirements,and then selects a service path through weight relationship ？ According to differ- ent Qos requirements from different users, a different form of service portfolio will be formed, and meanwhile a different service relative weight will be built ？ Ultimately for different users,a different service portfolio will be recommended in order to better meet the Qos requirements.
