| 摘 要： | 为提高云制造环境下组合云服务的柔性,提出一种基于QoS的组合云服务自适应调整机制.该机制将可靠性、可用性、时间、价格和柔性度作为云服务的QoS特征,给出各特征值的量化方法和云服务QoS包含度的定义;对云制造环境下可能产生的异常进行了分类和抽象,将自适应调整逻辑引入组合云服务,建立了组合云服务自适应调整模型,并给出相应的调整算法和调整逻辑.设计了仿真实验,实验结果验证了所提方法的可行性和有效性.

| Abstract: | To improve the flexibility of the composite cloud service for cloud manufacturing environment,an adaptive adjustment mechanism was put forward based on QoS.Taking reliability,usability,timeliness,price and flexibility as QoS characteristics,quantitative methods for those characteristics and for the QoS containing degree definitions of cloud services were provided.Exceptions possibly generated in a cloud manufacturing environment were classified and abstracted.By introducing the adaptive logic into the composite cloud service, the adaptive service model was built.The corresponding adaptive algorithm and logic were also presented. Finally,a simulation experiment was designed and carried out.The results showed that the adaptive adjustment method was feasible and effective. |
