摘要: 分析了动态联盟特性及其对工作流系统柔性方面的具体要求,归纳出柔性的两个方面,即柔性流程建模和系统柔性执行,并提出了抽象建模方法。该方法描述各个业务的共同部分,在流程运行中定义流程的抽象模型、临时路径、节点及连接弧、节点类型和实例,具有很好的柔性。并提出了一个柔性工作流系统的体系结构,该结构支持图形流程定义、动态修改工具、实例管理器、活动调度服务、任务表单引擎和流程监控服务等。

关键词: 工作流, 柔性, 抽象流程, 动态联盟

Abstract: The characteristics of dynamic alliance and requirements on flexibility in workflow system are analyzed, and two points on flexibility are summed up: flexible workflow modeling, system flexible executing. Then an abstract modeling way is brought forward. The way draws the outline of the same part of all operation instances, and defines the abstract modeling, temporary paths, nodes and its connecting arc, and an example. At last, a structure of workflow system is designed, which sustains the graphic flow definition, dynamic modifying tools, case manager, active scheduling serve, task table engine, flow monitor serve and so on.

Key words: workflow, flexibility, abstract workflow
