Abstract: Abstract HAZOP (Hazard and Operability Studies) is a structured tool which is used to identify potential hazards by means of deviations which are applied in conjunction with pre-defined keywords and that, jointly, describe the process, activities, or operations of a system or asset under study. HAZOP seeks to identify not only different controls for potential hazards but also different ways to mitigate consequences. Based on a structured framework, a multicriteria decision model (MHAZOP) is proposed in order to contribute to the risk management process. It takes hazard scenarios, multiple consequence dimensions, and the decision maker’s preferences into account. As a result, a ranking of potential hazards is established, thus enabling response actions related to the risk management process to be implemented in a structured way so as to eliminate or mitigate existing risks.
