中文摘要: 面向服务计算(SOC)模式软件是以软件构件技术为基础,通过自主、开放的服务实体的互联、互通、协作和联盟来构筑,是对Internet下大量分散的软件服务实体的共享、集成和复用。SOC模式软件是否安全可信,服务质量是否有保障,是极其重要的基础性科学问题。项目拟以课题组前期863课题建立的QoS证据数据库为基础,研究SOC模式软件的QoS计算方法,以实现对运行态下SOC模式软件服务质量的动态监测与故障预测与分析。主要研究内容包括:①构建全生命周期的服务实体时序多维QoS证据指标体系;②构建连续时域的服务QoS表达模式;③基于QoS证据数据库,动态发现SOC模式软件服务调用关系,动态感知SOC模式软件服务组合的全息拓扑;④依据证据指标体系及服务组合的全息拓扑,基于混沌理论建立SOC模式软件的QoS计算模型。研究成果将能为SOC模式软件的可信度量与实时监测提供理论方法与技术手段。

英文摘要: SOC model software is based on software component technology. It is constructed through connections, cooperation and alliance among independent and open service entities. It is based on sharing, integration and reuse of plentiful software service entities on Internet. Reliability, security and quality of service of SOC model software are essentially important scientific problems. Based on the QoS-evidence database resulting from our earlier 863 project, this project intends to study the computational methods of SOC model software to the monitor service quality and analyze and predict fault under the running state. This project would focus on: ① Building evidence index system of service entity QoS based on life time theory, ② Building timing-multi-dimension expression patterns service QoS in the continuous time domain,③ Locating service invocation and dynamic awareness holographic topology of SOC service composition based on the QoS evidence database, ④ Establishing a QoS computation model for SOC software based on Chaos Theory, the index system of service QoS and the holographic topology of SOC service composition. Research results will provide theoretical methods and technical means for reliable measurement and real-time monitor of the SOC model software .
