摘　　要：基于流程与活动两个级别考虑,提出支持动态调度的工作流D-Flow Engine;从动态路由和流程多版本方面分析了其动态调度特性。通过在流程建模阶段扩展工作流管理联盟的工作流元模型相关定义,重点分析了动态路由和多版本流程迁移在流程运行阶段的调度实现。实践表明,D-Flow Engine提高了工作流的适应性,满足了企业对工作流动态性的需求。A workflow engine D-Flow Engine was proposed, considering both process level and activity level, it analyzed dynamic characteristics of dynamic routing and muti-version processes transition. It extended basic workflow definition that proposed by workflow management coalition in the process-modeling phase, and mainly introduced the runtime implementation of dynamic characteristics. Applied into enterprise practice, D-Flow Engine has improved the capability of workflow management system, and meet the dynamic needs of enterprise workflow.
