| 摘 要： | 在Web服务开发过程中,为了创建满足特定应用需求的新服务,需要将不同地理位置、不同服务提供者提供的Web服务按照一定的结构关系组合起来。在服务组合过程中,首先要保证服务执行的可靠性,组合服务的可靠性是Web服务最重要的QoS(Quality of Service)属性,是决定Web服务能否成功应用的关键。组合服务的可靠性不仅和服务之间的结构有关,而且和组合的条件也有一定的关系,因此传统的可靠性模型已经不再适用于Web服务。为了提高Web服务的可靠性预测精度,提出了一种基于控制结构的组合服务的可靠性模型,最后通过案例分析说明了该可靠性模型能够比较精确地预测服务可靠性。

| Abstract: | In the development phase of Web services,the services located in different locations and provided by different organizations must be composed together in order to satisfy specific business requirements.The reliability must be ensured for composite services first.The reliability of composite services is the most important QoS(Quality of Service) which can determine the popularity of the services.The reliability of composite services is affected by the structure of services and by the composite conditions.So,... |
