About me

Igor Razlivanov, PhD. I was born in Petrozavodsk in 18 may 1973. I graduated from the Physical-mathematical specializing boarding-school #45 by Leningrad State University in 1990. I graduated from the Physics Faculty of Saint-Petersburg State University in 1997. I have received the PhD scientific degree in St. Petersburg University of State Fire Service of EMERCOM of Russia in 2009. Scientific interests: geographic information systems, geodesy, land surveying, firefighting tactics.

XFireBrigade

Program XFireBrigade (c) Razlivanov I. N. (Razin73) 2007-2009

Version 5.1

Functions:

This is a program-simulator for teaching and testing the leaders of fire extinguishing in the field of firefighting tactics.

It is possible to use this program to analyze real fires, which have happened, and to make a forecast of the fire behaviour in the important buildings.

The floorplan, the location of the sources of the fire and the areas, which are unreachable to the fire, need to be loaded as vector initial data. Also the location of hydrants and fire-engines need to be prescribed.

Mathematical basis:

This program was developed on the basis of an integrated mathematical model of fire spreading and the fire extinguishing processes in the conditions of limited resources. This model was designed by Igor Razlivanov in the context of his dissertation work, which was performed for the Chair of firefighting tactics of St. Petersburg University of State Fire Service of EMERCOM of Russia.

The author of the program is a PhD of technical science in the field of mathematical modeling, numerical methods and program complexes (05.13.18).

Technology:

This program was developed using Java technology from Sun Microsystems.

Can run under any operational system, which has Java virtual machine.

Signature properties:

1. The physics of fire spreading and the fire extinguishing are taken in account in association with tactics processes. The program calculates the water expense, working time of firefighters and so on. This lets us determine the possibility or the impossibility of accomplishing certain purposes using given resources for firefighting.
2. Floorplans are used as initial data. It is assumed that the exact amount and location of fuel is unknown.
3. Program is designed as 2D simulator.

Scheme of the interaction between Physics and Tactics:

Integrated mathematical model:

1. Fire spreading is modeled according to the Huygens principle. It means that fuel distribution is uniform.
2. The extinguishing model takes into account required intensity of water supply and required treatment time.
3. Several tactical objects are taken into account as finite state machines. States and transitions are assigned for them.
4. Interaction procedures are determined for the fire, the extinguishing and the tactical objects.

Multilanguage support:

It is easy to add a new language in the program. Just make a copy of any existing language file, give it a name of your language in English and translate the phrases in this file.

Modules:

1. Settings module (xfbsettings.jar). Allows to select language and assign tick length.
2. Initial data module (xfbinitdata.jar). Allows to load vector data and set physical and tactical parameters of simulation.
3. Test module (xfirebrigade.jar). Allows to test or to teach.
4. Results module (xfbresults.jar). Allows to analyze results.

I designed an extremely simple and intuitive user interface to maximize application performance.
