Abstract
This chapter introduces a methodology based on Petri net to assess domino effects, emphasizing on probability analysis of higher level domino effects. Based on the definition of basic Petri net and modeling approach, two probabilistic analysis approaches for domino effects are discussed. The first is combining probability with Petri net to form the probabilistic Petri net (PPN), so that probabilities of accidents at any level of a domino effect can be determined through the probability reasoning of PPN. The second is based on the simulation of Petri nets. Each simulation represents a propagation process of a domino effect. In this way, the interaction that may exist in the probability analysis of accidents in a domino effect can be avoided. These two approaches are illustrated by vapor cloud explosion accidents occurring in storage tank area.
