基于移动代理平台Aglet的柔性工作流的研究与实现

Research and implementation of flexible workflow based on mobile Agent platform: Aglet

分析了柔性工作流管理系统的特点以及可移动Agent技术 ,提出了一种基于移动代理平台的柔性工作流管理系统的体系结构 ,并采用Aglet平台实现了原型系统 .在原型系统中 ,业务过程的定义封装在可移动的工作流引擎Agent中 ,MA (mobileAgent)迁移到各执行任务的角色所在节点 ,驱动并监控任务的执行 ;利用多个Agent之间位置透明的通信、协同工作 ,使得业务过程的定义在执行中可动态修改 。

The characteristics of flexible workflow management system and mobile Agent technologies are analyzed. Then an architecture of flexible workflow management system based on mobile Agent platform is proposed and a prototype system based on platform-Aglet is implemented. In this system, the definition of business process is encapsulated in mobile workflow engine Agent, which migrates to the sites where the roles executing tasks reside and then triggers the tasks and monitors the tasks' executing. The location-transparent communication and coordination among multi-agent enable the definition of the business process to be modified dynamically during executing and in this way the workflow flexibility is implemented.
