基于能力的动态任务委派机制

Capability-based Dynamic Work Assignment Mechanism

任务委派是工作流管理系统中的重要机制之一,文中引入多主体能力表示和基于能力的动态任务委派机制对工作流管理系统进行了改进。基于CDL,Larks等主体能力表示语言,提出了一种从语法和语义以及能力继承关系一体化的主体能力描述ACDLS语言,并重点研究了其匹配的策略、算法和阶段。试验表明,基于能力的动态任务委派机制能够为工作流管理系统在动态变化的企业计算环境下提供灵活高效的任务委派。

Work assignment is one of the essential mechanisms in workflow management system. Introduce the capability representation of muhi - agent and employ capabillty- based dynamic work assignment mechanism to improve the workflow management system. Based on capability description language such as CDL, Larks, an agent capability description language ACDLS which provides both syntactic and semantic as well a.s inheritance information about agent＇s capability is proposed and major capability matchmaking policies and algorithms are explored. Using ACDLS, an implementation of dynamic work assignment was built on Shark and JADE platform. The result shows that our approach can provide flexible and efficient work assignment in dynamic computing environments of enterprise.
