摘　　要：通过研究基于自适应控制中间件的Web服务组合执行引擎QoS管理机制,设计了基于QoS的自适应控制中间件架构,引入神经网络在线计算线程配额,实现了为不同等级用户提供区分服务的功能,为提高可变负载下单个执行引擎的高吞吐量和快速响应时间提供了一种有效的解决方案.Through the research based on QoS management mechanism in Web Service Composition Execution of self-adaptation middleware, self--adaptation middleware architecture based on Qos is designed. Besides, thread quotas computed online by neural network is introduced to realize the functions of providing differentiated services for different classes of users. Moreover, an effective resolving scheme has been proposed to enhance throughput and response time of single execution engine under the condition of changing loads.
