Many risk assessment software such as DNV, CASST-QRA, DOMIFFECT, Aripar-GIS, and so on have been developed to assess potential consequences of plants or installations to the surroundings, avoiding the complexity and possible huge workload of numerical calculation . These user-friendly tools only require some given inputs to obtain corresponding risk assessment results, which have been promising tools for potential complex domino accidents and Na-tech events . However, the accuracy of risk assessment results depends on the internal vulnerability model and accident consequence model. At present, no mature risk assessment software has focused on the multi-hazard coupling effects.
