“…The third type is called a stochastic transition and is used for modelling a process with random time. Owing to the variety of Petri nets [11], it is a powerful tool for modelling flexible manufacturing systems [14,15], multilevel hierarchical systems [16,17], multiprocessor systems [18,19], etc. Besides, Petri nets are capable not only of simulation [20,21], reliability analysis [22] and failure monitoring [23] but also of dynamic behaviour observation [24] and activity prediction [25].…”

To improve preventive maintenance, this study uses a hybrid Petri net modelling method coupled with parameter trend and fault tree analysis to perform early failure detection and isolation. A Petri net arrangement is proposed that facilitates alarm, early failure detection, fault isolation, event count, system state description and automatic shutdown or regulation. These functions are very useful for health monitoring and preventive maintenance of a system. A fault diagnosis system for district heating and cooling facilities is employed as an example to demonstrate the proposed method.
