Firefighting task allocation is the core of the forest fire fighting programs. Making use of information entropy method, combined with the fire brigades, fire fighting capability, difficulty and other factors, an analysis in the priority under the conditions of multiple fire sites and fire lines is made, so as to build up fire fighting mission efficient matrix and determine the optimal allocation scheme by using ant colony algorithm. The practice shows that this task allocation model for forest fire fighting under multiple fire sites situation is feasible and practical.

The Southern Alps, in particular the Canton Ticino, is the region of Switzerland that is most affected by the phenomenon of forest fires. Therefore, the cantonal authorities are continually confronted with problems of prevention, fire fighting and mitigation of the effects of forest fires. In this article forest fire management in Canton Ticino is analyzed in historical terms, verifying in particular the impact of the methods used and the improvement of technology addressing the frequency of events and the extent of burned surfaces. In this way it has been possible to show how a few structural measures (better organization of fire fighting crews and equipment, introduction of aerial fire fighting techniques, electrification followed by construction of shelters along railway lines, etc.) have rather reduced the extent of burned surfaces, while legislative measures such as restrictions of open fires help to reduce the number of forest fires.

Проанализированы нормативные требования к противопожарным разрывам от зданий и сооружений до границ лесных насаждений. Рассмотрены особенности лесных пожаров с точки зрения нормирования противопожарных расстояний между объектами защиты. Изучена возможность применения действующих нормативных методов расчета противопожарных разрывов между объектами защиты для определения противопожарных расстояний от зданий и сооружений до лесных насаждений, а также разработаны и обоснованы необходимые рекомендации. Рассмотрен пример расчета для здания, расположенного вблизи леса. The requirements for fire breaks in the Russian Federation are regulated by the regulatory requirements for fire safety. Most of the calculated methods of fire breaks between the objects of protection are based on the value determination of the heat flow transmitted from fire at one of the objects to the combustible materials of the neighbor object. The possibility of calculating the values of fire breaks between buildings and structures is provided in the «Methodology for calculating fire breaks between buildings and structures» (Appendix A of the set of rules SP 4.13130.2013). There are no regulatory requirements for calculating fire distances from forest area to buildings and structures. The relevance of such requirements is due to the development of mass construction in the territories located in the zones of possible spread of forest and other landscape fires. The analysis of the regulatory requirements for fire breaks from buildings and structures to the boundaries of forest area showed that the basic principles for justifying the values of fire distances are related to the types of forest area and the characteristics of the buildings and structures of settlements (fire resistance of buildings, fire hazard of structural elements, etc.). Calculations of fire breaks from forest area to buildings and structures have special features so, when choosing a fire scenario, the main mechanisms of heat transfer, the type of forest vegetation and the type of fire - riding, grassroots or underground - must be taken into account. To apply the provisions of the «Methodology for calculating fire-fighting gaps between buildings and structures» (Annex A of the Set of Rules SP 4.13130.2013) for assessment of fire distances from buildings and structures to the forest area there was developed a set of recommendations and there was given an example of calculation on a specific object. At the same time, the most unfavourable fire scenarios were selected. The calculated dependences of the heat radiation intensity on the distance in case of fire in a residential building and at a forest fire are obtained. Based on the calculation results there were determined the necessary initial data for the development of compensating fire-fighting measures to eliminate the possibility of forest fire spreading to the buildings and structures of the object.

In this paper, a reasoning model is proposed for energy efficiency task allocation in wireless sensor network. The presented energy efficient contract net protocol is used to implement the negotiation process. Multi-issue scoring function can evaluate the offer with multi-issues in a quantifiable way. An energy threshold is brought to decrease communications which will turn out to decrease nodes’ energy consumption. And the usage of energy threshold also promote the nodes with high level energy have more chance to implement tasks. The simulation results show that the allocation model has outstanding performance maintaining a fair energy balance and is energy efficient in negotiation process.
