Cloud workflow model construction based on reflection mode and supporting multi-tenant dynamical configuration

为解决云工作流中多租户需求变化的动态适应性问题,提出基于反演模式支持多租户动态配置的云工作流模型。该模型运用反演计算的思想,从过程模型、角色模型、接口模型和状态模型等方面对云工作流进行描述和控制,并通过租户元对象所控制的拓扑元对象、角色元对象、任务元对象、状态元对象及其提供的元对象协议来实现对租户需求变化的适应性调整。实例分析表明,模型能够满足业务流程变更、人员变动及服务资源异常所引起的云工作流的适应性调整。

To solve the dynamic adaptability of multi-tenant＇s requirement change in cloud workflow, a cloud work- flow model based on reflection mode and supporting multi-tenant dynamical configuration was proposed. By using reflective ideology, the cloud workflow was described and controlled from four aspects ~uch as process model, role model, interface model and status model. Based on the controlled meta objects included topology, role, task and state as well as their corresponding Meta Object Protocols （MOPs）, the adjustment f^r adaptability of tenant＇s re- quirement change was realized. The experinaent result showed that the proposed model could satisfy the adaptability ad- justment of cloud worldlow caused by business process changing, members exchange and abnormal service resource.
