摘　　要：Grafcet建模工具以Petri网理论为其理论基础,它可以为并发、同步系统建模。Grafcet由图形表示,直观、易理解,且有很强的逻辑描述和分析能力,被广泛地应用到工业中。本文运用Grafcet建立电梯控制系统的模型,并将它与状态图模型进行比较,说明Grafcet有强大的描述系统的能力,并且在建立复杂模型方面具有无可比拟的优势。Grafcet, drawing its inspiration from Petri nets, allows modeling of concurrence and synchronization. Grafcet, which is represented by graph, visual and easy to understand, is powerful tool for logic description and systems analysis, and has been widely applied to industry. Grafcet is used in modeling control system of lift, and is compared with state diagram, It shows that Grafcet has powerful description and hold remarkable advantage especially for large scale systems.
