Annotations languages:

The emergency situations (ES) as a special type of decision object are described in this article. Critical analysis of existing information-analytical systems (IAS) of man-made disaster is performed. The task of organizing activities for evacuation from disaster areas is formulated and divided into following sub-tasks: sub-task of forecasting the distribution of concentrations of hazardous chemicals (HC) and sub-task of forming an advisory nature of solutions to organize events for the evacuation of the population. The analysis of existing HC distribution models is performed and the best model is chosen. The analysis of knowledge-oriented technologies to solve the problem of forming decisions, recommendations on the organization of events was performed and the best technology is chosen. The procedure of interaction of two subtasks is proposed. A method that solves the above problem on the whole is developed.
