批处理过程的自动化提出了困难的问题，主要是因为它是必要的，同时与连续和离散模型操作。在本文中，我们分析了如何分层的方法在离散制造系统领域可以扩展到批处理系统。这种分层的方法产生了三个层次，这是由一个离散事件模型建模的控制政策（离散视图的过程）和连续模型的过程（连续视图的过程）。过程的连续模型和工厂的物理状态之间的一致性由事件发生器确保。该事件发生器被提出，并考虑各种情况下的变量。最后，一个离散事件建模的控制策略说明了通过一个例子，一批多用途工厂，使用Petri网。<<ETX>>
The automation of batch processes poses difficult issues mainly because it is necessary to concurrently operate with continuous and discrete models. In this paper, we analyse how the hierarchical approach used in the field of discrete manufacturing systems can be extended to batch systems. This hierarchical approach gave rise to three levels which are composed by a discrete event model modelling the control policy (discrete view of the process) and by a continuous model of the process (continuous view of the process). The consistency between the continuous models of the process and the physical state of the plant is ensured by an event generator. This event generator is presented and various cases of variables are considered. Finally, a discrete event modelling of the control policies is illustrated through an example of a batch multipurpose plant, using Petri nets.<<ETX>>
