Abstract
It may be difficult to establish the methodology for safe evacuation in the case of outbreak of a marine fire, by originating in the intricacies of the fire spread phenomena and the uncertain behaviors of evacuation based on human factors without uniformity. The suitable countermeasures have to be taken to cope with rapid spreading smoke that is apt to endanger even for personnel away from the division of fire outbreak. Besides, the existence of un-measurable factors such as the ambiguity of human behavioral patterns should be necessary to be considered the redundancy system for safe evacuation. Accordingly, the designing criteria for the safety of evacuation system consisted in evacuating routes and human flow control, is desirably instituted by grasping the personnel behavior based on the associated in simulations of smoke diffusion and evacuation.
The evacuation movement can be predicted considering the decrease of walking speed and the occurrence of self-isolation in psychological action with lowering smoke layer by the proposed method in this paper. The measured index of risk for the evacuation system is defined by using the results of a simultaneous simulation of smoke diffusion and evacuation. This risk index may be used the comparison between various safety systems and its validity is confirmed using the model of a common space in a typical cruising ship.
