A Fire-fighting system, as the name suggests is a system concerned with extinguishing fire using sensors. Such an automated Programmable Logical Controller (PLC) system uses a Jockey Pump, a Main Pump and a Diesel engine. The PLC also monitors the operation of the Diesel engine. In advent of a fire, there should be a continuous flow of water through the hydrant line, pressure of which is regula...

The Firefighter Problem was proposed in 1995 [25] as a deterministic discrete-time model for the spread and containment of a fire. The problem is defined on an undirected finite graph G = (V,E), where initially fire breaks out at f nodes. In each subsequent time-step, two actions occur: A certain number b of firefighters are placed on nonburning nodes, permanently protecting them from the fire....

Introduction In late June 2008, a large, dry lightning storm ignited thousands of fires across California. The largest of these fires became the Basin-Indians Complex Fire in Big Sur, along the State’s central coast. The fire burned over 240,000 acres (USDA Forest Service 2008) and required over a month of intense firefighting operations to contain the perimeter. Media reports and anecdotal acc...

The Firefighter problem is to place firefighters on the vertices of a graph to prevent a fire with known starting point from lighting up the entire graph. In each time step, a firefighter may be placed on an unburned vertex, permanently protecting it, and the fire spreads to all neighboring unprotected vertices of burning vertices. The goal is to let as few vertices burn as possible. This probl...

the awareness of administrative organization of rescue and relief operation from spatial and temporal dimensions is pre requirement of rescue and relief. this subject and existence of accessible transportation networks that can save their performance after emergency situations are the most important parameters in efficiency of rescue and relief operation. the position of firefighting stations a...

A virtual environment (VE) of portions of the ex-USS Shadwell, the Navy's full-scale fire research and test ship, has been developed to study the feasibility of using immersive VE as a tool for shipboard firefighting training and mission rehearsal. The VE system uses a headmounted display and 3D joystick to allow users to navigate through and interact with the environment. Fire and smoke effect...

Simulation of wildland fire suppression is useful to evaluate deployment plans of firefighting resources and to experiment different fire suppression strategies and tactics. Previous work of fire suppression simulation uses analytical models based on a continuous space. This paper presents a design of fire suppression simulation using a discrete event agent model based on a discrete cellular sp...
