What we are trying to build

Running Simulator

Tasks During Evacuation Fundamental Goal – moving people to safety. Tasks: Identifying the spatial Information (floor map, people location) Identifying accessible/safe region from inaccessible/dangerous region Identifying evacuation points (assembly area) Identify information awareness (sensors, communication capability) Determining evacuation plan Implementing evacuation

Components in the Simulator Map Safe zone Dangerous zone accessible/inaccessible region Evacuation destination Agent (actor) Civilian Commander (decision maker) First responder Device (IT technology) Sensors (camera, thermometer, motion detector, etc) Communication device (internet, cell phone, etc) Information Source (internet, database) Spatial External

Simulation Lifecycle Precondition: Processing: Post condition: Initial Spatial Information is Predefined Agent are scattered on the map External Information predefined : Class Schedule, etc Processing: Crisis Simulator update spatial information New information is released to the agents through sensors Agent Gather information from Sensor Gather information from Communication channel Make decision and Act Move Wait Requesting Information Pass information to other agents Information Source (ideally database) Update Post condition: All civilians move to evacuation destination or die Within timeout Metric is stored in File/Database

Crisis Simulator Fire Simulator Chemical Simulator Crisis Modeling! How fire spreads How smoke spreads How Fire/Smoke affect people Chemical Simulator How Chemical Spreads Crisis Modeling!

Spatial Information Presentation Semantic Map Resolution?? Multiple layers of grid Accessibility layer Visibility layer Safety layer Map to geo-map Accessible Layer 0 : accessible cell 1 : inaccessible cell Many other ways to present it Research area!

External Information How external information is applied in Crisis?

Agent Model Agent Civilian Fire Fighter Commander Role (Fire fighter/ Commander/ Civilian) Duties Set of Properties (depend on roles): Location (FF) Health Visibility Mobility … Knowledge E.g. Rule-based Case-based Baysian-based Awareness Sensors Communication Device Private Information Collection Actions: Ask for information Read information Receive Command Make a decision Pass up a decision Pass up information Move Wait …. Agent Civilian Fire Fighter Commander

Commander (special agent) Properties: Map Location of Human Schedule, classes, hazards … Actions: Collection Information Make decision disseminate command to Device/Civ./FR…

Device Model Commu. Device Monitoring Device PDA Cell phone Laptop Between Agent Monitoring Device Sensor Camera Provide Info. A test environment for people to bring IT solution Device Communication Device Monitoring Device

Visualization Model Visualize Information on Screen From different layer From different angle In time order In spatial order Zoom in Zoom out

Open Questions How to simulate crisis on map? Map is changing How civilians make decisions? How commander makes decisions? How to share information? How if there is communication failure? How if multiple commanders? …
