基于混杂Petri网的食品加工生产过程建模

Modeling of some food production processes based on hybrid Petri nets

根据食品加工过程的混杂特性 ,提出了一种基于时延混杂Petri网与微分方程机理建模相结合的方法 ,并对某食品加工过程进行了建模和分析 ,其模型体现了连续过程和离散事件共存的特性 ,具有一般性。此模型可以应用于生产过程的优化调度。

According to the hybrid property of a food production process, this paper combines Timed-Hybrid Petri nets and the traditional differential equations (HPN) to model and analyze some food processes. The model shows the concomitant characteristics of the continuous process and discrete events. It has universality and can be used for optimizing a schedule of a production process.
