摘要
电梯群控系统是一种典型的离散事件动态系统 ,这体现在乘客到达的起始层、目的层和到达时间的随机性 ,所以 ,很难用一个传统的数学模型表达式来表示。提出了一种应用面向对象Petri网对该系统进行建模的方法 ,该方法在对电梯运行情况充分研究的基础上 ,分别建立电梯运行和电梯控制器Petri网模型 ,从而构造电梯群控系统模型。该建模方法不仅适用于电梯群控系统 ,而且适用于其它离散事件动态系统。
Elevator group control system is a typical discrete event dynamic system,which embodies in origination floor,objective floor and arrival time of passengers.So we can't figure it with traditional mathematical model.A modeling method based on object-oriented Petri nets is presented in this paper.The method constitutes the models of elevator moving and elevator controller by studying elevator moving sufficiently in order to constitute elevator group control system model.The modeling method is applicable to not only elevator group control system,but also other discrete event dynamic systems.
