The concept of a regional information-analytical system for emergency situations is presented. The three-level architecture of such a system and the functions of its main components are described. A generalized model for assessing plans for eliminating the consequences of emergencies is described. The goals and peculiarities of the structural modules for the regional information and analytical system for the prevention and elimination of emergencies are detailed; some examples of the implementation of local subsystems for Ukraine are considered.

Problem of decision-making in planning and elimination of consequences of emergency situations is considered. Sources of increasing of the effectiveness of measures oriented to prevention and elimination of consequences of emergency situations are discussed. Importance of decision-making in the process of the prevention, localization and liquidation of consequences of emergency situations is underlined. Problems of determining rational resources and funds to be allocated for prevention and liquidation of emergency situations are discussed. The main goal of a system for protection from emergency situations is defined as reduction or prevention of damage to human health and life, the objects of the economy and the environment arising as a result of accidents, catastrophes and natural disasters. Strategy of effective decision-making in planning and elimination of consequences of emergency situations is proposed and discussed. A system of partial indicators that characterize the prevented damage from emergency situations is proposed. To find the optimal resource allocation corresponded to the predicted disaster, the method of ideal point is used. Some examples are given and discussed.

The paper considers situations of the impact of various natural disasters on the electricity generating system as part of the energy system of a city or region. The impact of natural disasters in large part change the electricity consumption patterns, which makes it necessary not only to restore the power supply system, but also to conduct a complete review of its operation (reengineering). The paper discusses information technologies that provide a procedure for the reengineering of the electric power system when it is restored after an aggressive external influence, for example, a natural disaster.
