Record of efficiency indicator in controlling radio communication in fire service units

Purpose. Peculiarities of controlling radio communication when eliminating consequences of man-made disasters are considered. As an indicator that determines the purpose of control, the efficiency of communication in radio network deployed at a fire extinguishment site is considered. Methods. To assess the quality of work and the rationality of the radio network use, an efficiency indicator can be applied. This indicator is calculated using the methods of probability theory. Promptness is presented as a quantitative (probabilistic) assessment that the message will be transmitted to the required subscriber within a time less than the specified one. Findings. It is proposed to use radio communication efficiency indicator in the process of controlling radio communication during field work performed by fire units. Examples of its calculation for a radio network of three subscribers are given, the corresponding graphical dependencies are constructed. Research application field. The obtained results can be used to ensure safety in extinguishing fires and eliminating consequences of man-made disasters. Conclusions. It is shown that process of controlling radio communication can be considered as providing the required value of the efficiency indicator. In this case, the task of controlling radio communication will lie in excluding critical control modes, when network subscribers have an urgent need to contact other participants, who, in turn, are already communicating with network subscribers.
