In this article, an integrated model combined with Petri net and SDG (Signed Directed Graph) has been presented firstly, which is the first method of modeling.However, this method has advantages.

• 本文首先对间歇生产过程系统进行了一种模型的建模，该模型将Petri网与SDG(Signed Directed Graph)模型的基本思想相结合，建立了一个将二者元素相结合的整体模型，作为建模的第一种思路。
