Usually as a society develops, its members require more concrete and reliable
mechanism to guarantee their lives safer. The effect of this anxiety reaches maritime
applications also and naval engineers approach this issue in the view of
‘‘Design For Safety’’, which focuses engineers’ efforts to make safer ships on the
design stage. In this context, many naval engineering research teams are endeavouring
to develop new and advanced ship evacuation models and to apply them to increase the degree of human safety at sea. Furthermore, some evacuation models
that are currently used for land structures expanses its application to maritime
field. But these approaches have some shortages and we are developing a new
evacuation model IMEX (intelligent model for extrication simulation) to overcome
those. IMEX has two core sub-components, pedestrian dynamics model and
human behaviour model. Pynamics, which is based on discrete element method,
integrates all the forces including motion of ships to solve physical interaction of
evacuees. For human behaviour model, intelligent human agent is implemented on
the basis of PECS model that is referred to as one of the best models for human
behaviour modelling. This paper (1) describes background of ship evacuation
model and overall structure of IMEX, and (2) explains its pedestrian dynamics
model and human behaviour model in detail.
