分布式工作流系统的柔性管理

Flexibility Management in Distributed Workflow System

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。

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.
