【摘要】 随着组合服务的普遍应用,其在运行时的服务质量保障问题变得越来越重要。从而,针对组合服务自适应执行的服务QoS保障问题成为设计组合服务自适应运行平台需要考虑的一个主要问题。根据组合服务的自适应运行平台的要求,详细介绍了面向组合服务自适应执行的环境感知引擎的设计与实现,对系统的关键问题做了分析,并搭建实验环境对环境感知引擎进行了测试。实验结果表明该系统满足组合服务自适应运行平台的要求,能根据环境变化为组合服务执行引擎提供服务执行时间的变化消息,为组合服务自适应动作提供决策依据。更多还原

【Abstract】 With the widespread application of composite services,how to assure the quality of composition service in the run-time become increasingly important.Thus,the combination of services for the implementation of service QoS adaptive security issues become adaptive composite service operation platform design to be considered a major problem. This combination of services according to the requirements of adaptive operating platform,detailed composite service-oriented context-aware adaptive execution engine design and implementation of the key issues on the system were analyzed,and take the experimental environment for achieving the situational awareness engine were tested.Experimental results show that the system meets the operating platform for adaptive combination of service requirements, according to environmental changes for the composite service execution engine changes in service delivery execution time news service for the combination of adaptive action to provide basis for decision making.更多还原
