In the middle of this paper, six kinds of basic Petri net flow modules which conform to Workflow model are put forward. The method of transforming Petri net flow model to XPDL and constructing Petri network using XPDL is given. These establish the base for different modeling method using Petri net. And these extend EJB task engine and Subprocess task engine of distributed Workflow Management System——Flowstep.

文章中心部分是提出了符合工作流元模型的六种基本Petri网流程模块，给出了由Petri网流程模型向XPDL转换的方法以及由XPDL构造Petri网的方法，为不同的建模方法利用Petri网分析技术奠定了基础；扩展了分布式工作流管理系统Flowstep的EJB任务引擎和子流程任务引擎。

To prepare studying hierarchical intelligent control system of material flows in mineral processing plant further, picturing, transition rulers, analytic methods, relevance matrix and dynamic equation, defect in applying of Petri network, fall short of orient object models applying are discussed after technology of formalization model built, non-formalization built and compound model. And Petri network system with time attribute is expanded opening network system with interface of input and output. The network system expanded with all attributes of basic Petri network model has hierarchy and recursiveness, can be analyzed with mathematical tools of network system and can deal with concurrent and asynchronously also.

为了对选矿厂生产物流递阶智能控制系统的进一步研究奠定基础，本文在讨论了形式化建模技术、非形式化建模技术和复合模型的基础上，研究和分析了Petri网的图形表示、变迁规则、分析方法、关联矩阵与动态方程、Petri网模型应用中的缺陷、面向对象模型应用中的不足，并把采用赋时的Petri网系统扩展成为对外界有输入和输出接口的开放网系统，扩展后的Petri网具有递阶性和递归性，同时保持基本Petri网的所有性质，使模型仍可采用网系统数学工具进行分析，并可处理生产物流系统中的并发性和异步性。

In order to solve the route search problem in stochastic Petri net, the feature of reliability is introduced into each transition, and suppose that the lifetime distribution of a transition obeys the Weibull distribution model, then a memorial stochastic Petri net with reliability whose elements can record a little information is proposed based on the ant colony optimization algorithm and features of the memorial stochastic Petri net.

为了解决随机Petri网的路径寻优问题，在变迁中引进了可靠性的特性，并假设变迁的寿命服从威布尔分布模型，然后根据蚁群算法和时间Petri网的特点提出了一种网络元素可以记录少量信息的带可靠性的记忆时间随机Petri网。
