摘　　要：本文针对Web服务组合高效运行平台需求,介绍了服务组合支撑平台StarService Flow的系统结构,并重点探讨其流程引擎的运行管理技术,提出了基于事件驱动的运行时对象管理机制和基于可调线程池的两级并发机制。系统测试表明,StarService Flow具有良好的并发处理能力和可伸缩性。We address the needs for an efficient Web service composition platform and present the research and design of StarServiceFlow, which is a service composition platform, in this paper. Based on introducing the architecture of StarServiceFlow, we focus on the process engine design techniques for supporting large-scale service composition, including the eventdriven runtime object management mechanism and the two-level concurrency mechanism based on an adjustable thread pool. Evaluations have shown that StarServiceFlow behaves well for the concurrent process execution in large-scale composition scenarios.
