Risk assessment in a chemical plant with a CPN-HAZOP Tool

In a previous research, a tool integrating the HAZOP analysis method and Coloured Petri Net formalism to support the analysis carried out by specialists during a HAZOP brainstorming session has been provided. In that work, the tool was used to simulate the behaviour of a few components of a chemical plant while diverse abnormal scenarios occur. In the present work, other types of components have been modelled and the behaviour of the plant has been simulated demonstrating its ability to model more complex components, simulate diverse failure types, hence, reducing the total time required to complete the analysis compared to a standard HAZOP assessment approach.
