| 摘 要： | 服务组合正在成为一种对商业过程、Web服务、多媒体应用等提供按需服务的关键技术.在服务组合中强调两个重要的因素:组合服务路径的质量和服务中断的恢复.用一种新的方法研究服务组合问题,提出了一个优化的服务干扰理论模型,给出最小干扰服务组合和恢复的启发式算法(MISCR).仿真结果表明,在发现服务路径时,MISCR算法优于传统的算法,提高了组合服务的健壮性和稳定性.

| Abstract: | Service composition is becoming a crucial technology to enable on demand business process provision,web services,multimedia applications,etc.There are two important issues to address in service composition: the quality of the composed service path and the failure recovery in service disruptions.In this paper give a new way to study QoS-based service composition.First,an interference model is proposed to quantitatively characterize and measure the interference.Then,based the model,we present a minimum interf... |
