摘　　要：为了适应复杂环境下动态多变的业务需求,对以服务为核心的流程动态编排和再造提供支持,提出了基于JBPM工作流的流程动态编排与迁移方案,该方案分析了目前工作流在流程编排方面的局限性;结合柔性工作流的特点,给出了流程动态编排的模型,并对流程变更所产生的4类操作做了形式化的描述,通过对流程变更引发的流程进行迁移继而实现接续执行这一问题的研究,提出一种流程迁移算法。最后通过实例和性能测试工具验证了算法的可行性和高效性。In order to adapt to dynamically change business needs in complex environment and to provide support for dynamical process scheduling and recycling that centralize service,a dynamical process scheduling and migration schema based on JBPM workflow was proposed.This schema analyzes the limitations of workflow in terms of the current process scheduling,displays the dynamical process orchestration model combining with the characteristics of flexible workflow and formally describes the four operations produced by process changes.Through the study on the issues triggered by the migration process and continual performing,aprocess migration algorithm was proposed.Finally,instances and performance testing tools were employed to verify the feasibility and efficiency of the algorithm.
