Abstract

Purpose. The organization of communication in fire service units at eliminating consequences of man-made disasters or fire extinguishing at the site has its own features, which are determined by the officials’ interaction procedure. The article considers the features of private cases models of radio communication organization in the units of the State Fire Service at the site of fire extinguishment or elimination of man-made disasters. Probabilistic characteristics of these models have been investigated. Methods. The authors analyzed the existing officials’ interaction models using radio communication directly at the site and in the process of eliminating man-made disasters. Findings. Graphical dependencies of probabilities of communication network states on time parameters of radio exchange are presented. It is determined that at organizing and controlling communication at the site of fire extinguishment or elimination of man-made disasters, knowing the required characteristics of the communication network (including the probability of being in critical and free states), it is possible to determine the allowable range for the values λ (frequency of the need for communication) and µ (rate of communication channel release). Research application field. The obtained results can be used in organizing and managing radio communications for ensuring safety at fire extinguishment and elimination of man-made disasters. Conclusions. It is shown that the interaction process of fire extinguishment and elimination of man-made disasters subjects depends on the use of radio communication facilities. Under certain conditions, critical modes may occur in radio network, which will interfere with means and forces management, as well as affect the safety of the participants of this process. In this case, the task of radio communication control will be to estimate the possibility of occurrence and exclusion of critical modes, which can be done on the basis of the obtained dependencies of communication network states probabilities on time parameters of radio exchange.
