某些系统的行为具有高速动态演化的特征。系统的运行会引入新的组件，而其他一些组件则会消失，组件之间的链接是动态设置的：组件有时与给定的组件交互，有时与其他组件交互。在结构固定的Petri网中很难捕捉到这种演化，但必须尊重Petri网的语义，并保留应用结构分析技术的可能性，本文介绍了处理这一问题的Petri网的两种扩展：通信网和合作网。它们可以将系统建模为一组网络，这些网络封装了它们的行为，同时通过消息发送或客户端/服务器协议进行交互;一个网络可以实例化另一个网络，并且网络之间的链接是动态的。给出了一个算法，它捕捉这种动态性，通过建立一个单一的固定网络，其行为相当于一个完整的系统。
The behavior of some kinds of systems features a high rate of dynamic evolution. The system running causes the introduction of new components whereas some others disappear, and links between components are dynamically set: a component sometimes interacts with given components and sometimes with others. It is uneasy to capture such evolution inside Petri nets whose structure is fixed; but it is necessary to respect the Petri net semantics and keep the possibility to apply the structural analysis technics.The paper introduces two extensions of Petri nets dealing with this problem, Communicative Nets and Cooperative Nets. They enable to model a system as a collection of nets which encapsulate their behavior, while interacting by means of message sending or a client/server protocol; a net may instantiate another net, and the links between nets are dynamic. An algorithm is given which captures this dynamicity by building a single fixed net whose behavior is equivalent to a whole system.
