Example: Initial Phase of a Forest Fire
The event may have started in some unidentified way but it is discovered by some individual who just happens to be present at the place.
This individual corresponds to a generic agent and will act as a first responder. After having consulted the Handbook of protocols, which is available or accessible from his personal digital assistant, the generic agent turns into an agent with the role of a 911-caller.
After the call is placed a 911-agent (operator) is activated. The two agents communicate and the caller transmits the event description. Once the event description is transmitted the call is finished and as the caller hangs up the agent goes back to his normal role.
The 911-agent, on the other hand, consults the Handbook, if required, and as a consequence engages in its role as an activator of other agents who in this case are the agents at the police and fire departments.
