Overview

Another BigBang! System Details & Structure Current RCRSS Overall

BigBang in Kobe! Devastating earthquake left more

than 6500 citizens dead in the city of Kobe, Japan on 1st of Jan. 1995.

A meeting at the city hall on April 1999 led to the Rescue simulation project, formally proposed as a competition in Robocup.

Rescue Simulation Design Issues

We need: A general world model(city simulation

issue). To model the disaster (disaster

formulation). To act upon the situation.

Simulation Progress

Kernel sends sensory information to each agent module.most of this information is visual information. This information is mixed with some errors.

Each agent module decides what actions the individual should take, and send it to the kernel. This message is called command.

The kernel gathers all messages sent from agent modules, and broadcasts them to the component simulators. Commands are sometimes filtered e.g late commands or commands from dead agents are discarded.

The component simulators individually compute how the world will change based upon its internal status and the commands received from the kernel. These results are then sent back to the kernel

The kernel integrates the results received from the component simulators, and broadcasts them to the GIS and the component simulators. The kernel then increase the simulation clock, and notifies the viewers about the update.

Having being requested for information from the viewers, GIS sends the updated information to the viewers. (GIS keeps track of the changes in the simulated world).

Current RCRSS Overall

The System Is: A multi-agent system. A core-based system. A distributed simulation system. Running under Linux. Open source (in C++).
