Express Risk Assessment throughWeb Access to Simulation Data

摘要

A prototype of an express risk assessment system is proposed and implemented as a combination of a distributed simulator and a web interface. A case of aerosol dispersion in an urban environment is investigated. Fast response of the system is achieved by replacing complex 3D simulations with information retrieval from aerosol dispersion database. The database is created by extensive simulations of different aerosol dispersion scenarios. Cluster or grid computing environments are most suitable for these type of simulations. The reduction of system response from a few days to several seconds can be achieved compared to realtime 3D simulations.
