ABSTRACT
This paper targets the development of a dynamic multimodel framework that can facilitate BIM based fire protection and evacuation planning and training. It is inspired by the EU project BEST, which develops a novel real time hazard and evacuation simulation system and integrates three models, namely CFD simulation, crowd simulation and dynamic building model. The latter provides comprehensive information about the building, but this information is static and represents the building in an idealized state where no changes are happening over time. In current practice, the building model is input to simulation tools as a static model. We propose an ontological framework extending the standard ICDD implementation (ISO 21597) to a dynamic Multimodel Framework aiming to explicitly allocate multiple dynamic values to elements in the building model. This enables consideration of dynamically changeable building elements’ status at simulation runtime and hence real-time interoperability of the interlinked simulation components and modules.
