10 10 AuthorComments Ferdous et al. (2011) The authors defined event tree analysis (ETA) as the technique to describe the consequences of an initiating event and to measure the likelihoods of possible outcomes of the event. Badreddine and Ben Amor (2010) The analytical hierarchical process (AHP) has been utilized to add the preventive and mitigation barriers within the Bow-tie (ETA & FTA) model Rinaldi (2009)Utilization of GIS in fire risk assessment Sun et al. (2007)The study shows that, the utilization of GIS in the model has endorsed the efficiency of the risk assessment system for the potential fire hazard.
