MODEL OF CYCLIC MONITORING OF LARGE FIRES AND SEARCH AND RESCUE OPERATIONS
Currently, one of the fundamental elements of successful management of forces and means, both in a fire and during search and rescue operations, is a high level of information support for officials. The qualitative level of the necessary information for the fire extinguishing manager, for the head of the search and rescue operation at the present stage is provided through the use of mobile monitoring tools. The scope of application of mobile aerial monitoring tools is constantly growing, thereby increasing the number of tasks that need to be solved when monitoring a large fire and aerial search in the natural environment with their use. This increases the load on mobile monitoring tools as a technical device in ensuring trouble-free operation. The solution to this problem is possible thanks to modeling and the use of backup monitoring tools. With an increase in the time parameters of monitoring and the number of mobile devices in the group, the functional load on the entire monitoring system increases, therefore, the probability of failures of monitoring tools increases, which entails a decrease in the quality of information support. The aim of the work is to obtain analytical dependencies to describe the probability of the state of the monitoring system in operation and during recovery to solve a set of tasks for planning and organizing the extinguishing of large fires, as well as reducing the time parameters for the location of the search object. The article considers a probabilistic approach to assessing the quality of information obtained during the implementation of constant monitoring of fire parameters during the extinguishing of protracted fires and aerial monitoring of large areas during search and rescue operations. Analytical dependences have been developed to assess the limiting probabilities of the state of the system during its discrete operation to solve a set of tasks for planning and organizing the extinguishing of large fires and conducting search and rescue operations.
