I. Introduction
The effectiveness of the functioning of the geoinformation system for the safety of emergency situations of a medical and biological nature, the functions of which are implemented according to the principle of the classical control circuit and are schematically presented in fig. 1, in many cases depends on the operation of the anti-crisis decision support system which is based on the synthesis of information and communication technologies, information storage and presentation tools, computer decision support tools. This decision-making support system can be presented in form of situational center which means a set of methods, algorithms, management decision-making models and a set of technologies both supporting and implementing these decisions [1], [2]. The development of such approaches to adoption of effective anti-crisis decisions regarding implementation of early actions as intended, which are aimed at minimizing consequences of medical and biological emergency, is urgent task.
