DETERMINATION OF THE OPTIMUM PERIODICITY OF MAINTENANCE OF THE FIRE ALARM SYSTEM AND NOTIFICATION AT MILITARY STORAGE FACILITIES OF AMMUNITION (AVIATION ATTACK MEANS)

The work examines the topical issue of increasing the reliability of fire alarm and warning systems (FALS) at ammunition storage facilities (aviation weapons). Using a semi-Markov random process, a mathematical model of the operation of FALS was built, analytical calculations of the average time the system is in a working condition, in any condition, and the frequency of the random process entering different states, which allows to find the value of the coefficient of technical use, taking into account various operating parameters of FALS. The proposed method of mathematical modeling involves the application of the diffusion non-monotonic law of distribution of the time of stay of FALS in the states of the model. Based on the obtained analytical dependencies, it is possible to find the maximum value of the coefficient of technical use, which will correspond to the optimal frequency of maintenance of FALS. The results obtained in the work can be used to develop a methodology for increasing the efficiency of FALS operation by determining the optimal periodicity of their maintenance, which will contribute to increasing the reliability of FALS at military storage facilities for ammunition (aviation weapons) and, in the long term, will improve the level of protection of these facilities objects from the occurrence of man-made emergency situations.
