制造云服务组合的自适应异常处理框架

Adaptive Failure-handling Framework for Manufacturing Cloud Service Composition

针对云制造环境下服务组合的自适应异常处理问题,从环境感知的角度对导致制造云服务组合QoS变化的异常情况进行了分析,并提出了相应的自适应调整机制,在此基础上构建了一种制造云服务组合的自适应异常处理框架。该框架能够自动地产生与需求相匹配的异常恢复策略,并将用户的不同异常恢复请求与制造云服务组合相结合。最后,提出了一个云服务组合实例来证明该框架的可行性。

To cope with the problem of adaptive failure-handling for service composition in the cloud manufacturing,the failures which may influence the QoS of cloud service composition were analyzed from the perspective of environmental perception.The corresponding adaptive adjustment mechanism was proposed,based on which,an adaptive failure-handling framework of cloud service composition was established.This framework can dynamically generate the requirement-matched failure recovery strategies and combine various failure handling requirements of users into the cloud service composition.Finally,a cloud service composition instance was presented to prove the feasibility of the framework.
