摘要: 云制造环境下服务资源进行动态组合时不可避免地遇到内、外部环境的不确定性,这些不确定性因素直接影响到制造云服务组合的执行成本、效率和质量。为了有效提升制造云服务组合的柔性,需要对其柔性能力进行测度。在假定某待选云服务集中的各服务资源能够以不同的效率替代完成任务的基础上,建立了考虑制造云服务组合柔性的效率柔性、冗余柔性、路径柔性和任务柔性的四维属性测度方法。最后,结合具体算例对该方法的应用过程进行了分析。

Abstract: In the process of resource service composition in the cloud manufacturing environment, inevitably there are many uncertain factors from internal and external environments influencing the dynamics of cloud service composition, which directly affect its operating cost, efficiency and quality. To effectively improve the flexibility of cloud service composition, this article needs to measure the flexibility. Based on the assumption that each resource service in the candidate cloud services set can substitute others to complete tasks with different efficiency in case of disturbance occurring, we propose a measurement method of cloud service composition flexibility. The method takes into account four attributes, including the efficient flexibility, redundancy flexibility, path flexibility and task flexibility. Finally, this cloud service composition flexibility measurement method is verified with an example to illustrate its application process.

Key words: cloud manufacturing, cloud service composition, flexibility measurement, redundancy flexibility
