First, a maximal deadly siphon can be obtained by using the mixed integer programming technique, and a monitor is added to a minimal siphon that needs to be controlled, which is derived from the maximal deadly siphon in order to ensure the controllability of all siphons of Petri nets.

首先对Petri网模型运用混合整数规划算法求取一个最大的死信标，然后从最大的死信标中求取一个需要受控的极小信标，并对其添加控制库所，从而保证所有信标的最大可控。

A polynomial algorithm about minimal marking of structural live Petri nets was presented. In an empty marking net, it was verified that the reproducibility can be held under operations. These results can be used in process mining.

本文还利用结构理论解决了结构活网到活系统的极小标识求解算法，并对Petri网的一类特殊性质：空标识可再生性进行了求证，解决了空标识可再生网在运算中的保持条件。

Secondly, the monitoring and diagnostic integration concept was proposed for the hybrid system, based on this assumption, the monitor and diagnosis technology for running process of DMF recovering vaporizer was analyzed. The hybrid Petri nets information model describing the miscellany characterization for production process and controller model for diagnosis and decision were given. The combined propagation condition between equipment failure and heavy disturbance of continuous parameters was also discussed. The simulation results suggest that the methods in this work are valid.
