【摘要】 柔性问题是当前工作流系统中的研究热点之一。讨论了分布式工作流系统的柔性管理问题。在模型定义中用工作流接口-工作流定义的结构替代传统的工作流定义,将工作流定义具体划分为预定义操作包和扩展定义操作包,实现了动态的功能自适应;在执行过程中动态进行注册和注销执行机,引入协调机和路由规则库,实现了可变的路径自适应。更多还原

【Abstract】 The research about the flexibility is one of hot topics in fields of workflow system currently.In this paper we discuss the flexibility management in distributed workflow system.The workflow interface-workflow definition substitutes the traditional workflow definition in current workflow model definition,and the workflow definition is classified into pre-defined operation packets and extended-defined operation packets,so the dynamic function self-adaptation is realized.Executing engines can (register) and logout dynamically in executing,and the concerted engine and the route rules collection are appended,so the alterable route self-adaptation performs successfully.更多还原
