  1. A-TEAM: Advanced Training System for Emergency Management WP02: Simulation Exercises Kostas Karatzas Department of Mechanical Engineering Laboratory of Heat Transfer and Enviromental Engineering Aristotle University of Thessaloniki, Greece

  2. Objectives • To develop a rich and comprehensive set and case library of emergency simulations for typical emergency cases; • To build a set of example cases for the case-based reasoning tools of the training system; • To select,configure in terms of their specific parameter sets, and simulate case examples to represent typical situations, frequently encountered that are also characterised by their didactic value; • To prepare the underlying simulation models for their direct integration into the Emergency Management Trainer (EMT) through a modular client-server architecture (WP5).

  3. Description of work • Definition of the example cases: done • Preparation of the data sets for each case: done • Simulation of the emergency cases: done • Post-processing the results for use with the case-based reasoning, for inclusion as explanatory examples, and for direct integration in the EMT and interactive simulation: done • Overall: modelling tools for the training cases have been selected, and they have been used within WP5 (either directly or as a CBR component)

  4. Annex C to the Deliverable D02.0 has been created (following a reviewer’s request included in the 3rd review report), describing the models used for the case studies treated; • P.O stated that it accomplishes reviewer’s request (letter dated 06 Feb. 2003) WP has finished!

  5. Summary of emergency scenarios and corresponding models

  6. Models vs. cases ( X = “on line”)

  7. The challenge: Parameterize tunnel accident characteristics for proper • Case description (for training) • Case simulation (scientifically sound) • The tool: CFX-5 (state of the art CFD) • The result: scientifically correct, important for the risk sector simulation results, successfully used via the CBR module Tunnel case simulation (1/4)

  8. Preparation needed: • For proper parameterization: more than 80000 initial runs of a Gaussian model • For proper simulation: • Hardware requirements: disc space ~ 3GBytes • CPU: Pentium IV • Number of runs: 40 cases • CPU time needed: 24 h / case (not including pre-post processing) Tunnel case simulation (2/4)

  9. Preprocessing needed: • Checking of • Case parameters • Simulation parameters • Preparation of run (grid generation etc) Tunnel case simulation (3/4)

  10. Post processing required • Extraction of data (100 computer-hours of “extracting” process needed) • Graphics representation • Comparisons with similar results • Formatting, “Packing” for CBR usage and “post” Tunnel case simulation (4/4)

  11. Sufficient/successful input for CBR (random checks showed good agreement between CBR and simulation results) • Sufficient representation of phenomena • One conference presentation and one international journal publication Tunnel case simulation results

  12. Scientific exploitation • Ossanlis I., Karatzas K., Kaprara A., Louka P. and Moussiopoulos N.
