“…Results obtained by using the traditional MULTIMOORA method suggest that the risk rankings of equipment surface overheating, improper handling of lit cigarette butts, and improper use of fre in the kitchen are almost the same as that proposed in this paper, which indicates that the weight and status judgment of some risk sources in the ranking process of the new model are consistent with that of the original model, and the two methods share the same ranking mechanism. Failure of fre alarm devices, open fre operation in nonoperation areas, and spontaneous combustion of cargo are considered some of the main causes of ship fre [35], and the hazard ranking obtained by traditional methods fails to fully refect its importance. Terefore, compared with the traditional MULTIMOORA method, this paper adopts the peer-to-peer consensus model to aggregate the group evaluation information with a highlight on the interaction between risk factors.…”

Impact of a Change from an Aluminium- to a Composite-Type Aircraft on Wind-Assisted Aviation-Fuel Fire Dynamics - a Numerical Study

“…A hybrid model was developed for human-factor analysis of engine-room fires on ships by taking into account the wide range of both sources of fuel and sources of ignition within the engine room [20]. A new framework which is based on grounded theory, fault tree analysis and Bayesian network, was proposed for identifying critical risk factors in ship fire accidents [21]. The recent cases of ship fires explosions due to lack of safety awareness were analysed [22], suggesting the necessity to research precise evacuation plans, develop ship structure/materials reinforcing fire resistance to secure more time for evacuation, and to enhance people`s safety awareness by implementing thorough safety training.…”

A CAST-Based Analysis of the Metro Accident That Was Triggered by the Zhengzhou Heavy Rainstorm Disaster

“…Current research on emergency management focuses mainly on the management of accidents [ 30 , 31 ], including the application of statistical methods to study accident characteristics [ 32 ], evacuation route planning in emergencies [ 33 , 34 ], accident analysis methods [ 35 , 36 ], emergency response methods [ 37 ], hazardous chemical leakage assessment [ 38 , 39 ], risk management [ 40 ], and the prediction of accidents with artificial intelligence [ 41 , 42 ]. There are relatively few recent case studies on the emergency management of natural disasters.…”
