Conference paper


It is shown that Petri nets [1] are also extremely useful for visualising cases of statistical dependency (s-dependency) between components in the context of safety and reliability engineering. Even though maintenance can result in sdependency, the thrust of this contribution is with sdependency due to component failures influencing other components. The examples presented here show convincingly that all aspects of Petri nets are potentially useful for modelling dependencies of many different types in practice. The starting point of Petri net design is always a thorough understanding of the dynamic processes involved. Surprisingly, theoretically plausible types of dependency, e.g. the linear superposition of failure rates, yield no plausible common type of Petri net models.
