云制造环境下制造云服务进行动态组合时会受到诸多不确定因素影响。不确定环境下，柔性较好的服务组合能更好地满足用户制造任务需求。为获取制造云服务组合柔性的评价结果，需要一套有效的服务组合柔性评价方法。在分析制造云服务组合各类柔性基础上，提出覆盖多类属性的制造云服务组合柔性评价方法，为相关企业构建和运用云制造服务平台提供决策理论和工具。

英文摘要：

Under the cloud manufacturing environment,cloud services be influenced by many uncer-tainties when they combine with each other dynamically.Under the uncertain environment,service composition with a better flexibility can execute users′tasks much better.In order to get the evalua-tion results of flexibility of the cloud service composition,we need a valid evaluation method of flexi-bility of the cloud service composition.Based on the analysis of multi-flexibility of the cloud service composition,an evaluation method covering many types of attributes of flexibility of the cloud service composition is suggested,which provides decision theories and tools for related companies to construct and use the cloud manufacturing platform.
