摘要
敏捷制造是当前制造业中的一个新型制造模式，代表着今后制造业的发展方向。本文首先综述了国内外的研究状况，简要介绍了实现敏捷制造涉及的工作流管理系统和Petri网建模及基于CORBA,Web的分布式技术。
其次，从生产经营的角度出发，分析了模具制造的流程，提出了模具敏捷制造工作流管理的模型（MAMWM）。并且针对模具敏捷制造生产系统中存在的特点，在基本Petri网的基础上扩充了定义，提出了面向Agent的单令牌有色Petri网（ASTCTPN）模型；把MAMWM转化为Petri网模型。
再次，在工作流参考模型中，工作流引擎是工作流管理系统的核心。通过对关键业务的实际开发需求的分析，在传统的关系数据库的基础上，提出了一个适用于关键业务开发的基于关系结构的轻量级工作流引擎的框架结构。根据模具敏捷制造工作流管理系统Petri网，具体给出了模具敏捷制造工作流模型的机构模型、信息模型和控制模型。
随后，提出了CORBA在模具敏捷制造管理系统的应用方法，建立了基于CORBA的四层开放体系结构。
最后，以java作为切入点，模拟实现模具敏捷制造工作流管理系统的引擎和体系结构的三个接口。将CORBA服务发布在BES，实现了在广域网上的访问和运行。

Abstract
Agile manufacturing （AM）is a new manufacturing mode in modern manufacturing industry. It is the developing direction of manufacturing industry.This paper first summarizes the research stituation of AM all over the world,introduces workflow management system and modling using Petri net and distributed technology based on CORBA and Web which are involved to realize AM.
Second, From the point of view of producing, the flow of mold manufacturing is analyzed and the mold agile manufacturing workflow model named MAMWM is put forward. According to the characteristics of mold agile manufacturing system, Based on the Petri Net, the definition is extended and the Agent-oriented single token and colored transition Petri net (ASTCTPN) is proposed. MAMWM is turned into the model of Petri Net.
Third.workflow engine is the core of the workflow management system in the workflow reference model. According to the analysis of the requirements to develop critical business applications, this paper presents a framework of a relationship-based lightweight workflow engine, which is built over the conventional relational database system.According to mold agile manufacturing workflow management system Petri net, the organization model, information model and control model of mold agile manufacturing workflow modle is proposed.
Fourth, Common Object Request Broker Architecture (CORBA) is used to mold agile manufacturing management system. The four-layer open architecture based on CORBA is constructed.
Finally,using the java as 切入点,the engine and the three interfaces of architecture of mold agile manufacturing workflow management system are stimulatelly implemented.accessing and running on WWW is implemented by deploying the CORBA services on the BES.
Keyword:mold,workflow.Petri.CORBA
