Existing Simulator

Limitations Static Scenario, no crisis scenario Assumption: every agent knows everything No different roles No room for IT solutions No interaction between agents

Simeva: a testbed for IT solution A platform to test effectiveness of information technology solutions for crisis response Dynamic scenario, driven by Crisis simulation Multi-roles autonomous agents Floor Warden, General Public, Fire Fighter, … Information technology incorporated Agents could either be controlled by computer programs or alternatively by human participants.

Map representation

Agent’s Position It is necessary to keep trace of the Position of an Agent mainly in two situations: When the Agents starts the assigned Evacuation Plan, he could be everywhere inside a room, so the distance between the Agent and each door of the room has to be calculated In his way towards the Exit, the Agent could change his mind or he could receive an Information with an updated Evacuation Plan; also in this case the distance between the Agent and the new door he has to pass through has to be calculated

Alghoritms Which alghoritm should be used to compute the best path for an Agent? It is correct to consider not only the distance, but also the occupancy: a path could be longer but faster due to a different occupancy Possibilities: Shortest-path Min-Max Flow Shortest-path which works not with distances, but with a factor which combines both the aspects (e.g. the ratio between the occupancy and the distance)

Alghoritms In any case, different alghoritms should be assigned to different Agents: so an Agent could behave in a different way accordingly to the alghoritm through which his Evacuation Plan is calculated The choice of the alghoritm should also depend upon the environment: for a building full of people, it could be reasonable to follow a Min-max flow model
