摘要： 研究了基于Web文挡数据交换的规范XML、动态Agent的结构模型,以及“推”、“拉”式作业调度算法,提出了基于工作流管理的智能制造系统结构。该系统首先把生产任务分解成单件子任务,构建制造过程流向图,根据流向图使用XML定义制造过程工作流文档,中央调度系统调用工作流发放作业任务,生产单元根据自身状态请求作业任务,完成作业后提交输出数据、更新任务目录,实现了制造过程的智能化、自动化。

Abstract: This paper deals with the criterion XML for exchanging data structure based on Web document, dynamic-agent architecture and the“Pull” versus “Push” job scheduling algorithm, proposes an intelligent manufacturing system modeled as adaptable agent-based workflows. Aworkflow-based architecture allows production management department to be able to decompose production task into individual subassemblysubtask, then to construct the digraph representing manufacture process, and establish manufacturing workflow. Production agent representingmanufacture workshop sends a request for outstanding jobs to be done to central mediator, central mediator choose a job for production agentaccording to waiting queue in the workflow and its capabilities, after the job has processed the events, production agent transfers the output data andupdates the metadata catalog. Flexibility and intelligibility are achieved in the process of production.
