Why FireGrid? • Effective response to emergencies (natural and man made) requires accurate & timely information of its evolution • Effective fire response requires consideration of emergency scenarios at the earliest stages of fire safety design • Simulation of fire+structure/human response mature enough to directly assist design, responder training and ultimately actual response • Integration of Grid, HPC and sensor technology offers the potential of super-real-time or “forecast” capability
What is FireGrid • SENSING • TRANSMISSION • ANALYSIS/DECISION/PHASE 1 RESPONSE • MODELLING/SIMULATION • FORECAST • FEEDBACK • ANALYSIS/DECISION/PHASE 2 RESPONSE
FireGrid Technologies 1000s of sensors & gateway processing Emergency Responders KBS and Planning Grid Maps, models, scenarios Super-real-time simulation (HPC)
