In the article, the authors provide a methodological approach to predicting the performance of repair and restoration bodies, taking into account the dynamics of the combat situation. Military equipment can fail for various reasons: due to limited technical reliability in peacetime, due to fire influence from the enemy in the conduct of hostilities, or the combined influence of both of these factors. Achieving the necessary reliability of equipment is even more complicated given the conditions of the combat situation (external factors) in which the equipment may be located. The authors proposed the probability of equipment failure as a result of limited technical (in-house) reliability and due to fire action by the enemy in the course of hostilities, as well as with the combined influence of the considered factors on his condition, defined as the probability of two joint events. Provided version of the simulation of reliability in peacetime and in combat. Equations of the probability of equipment uptime during its continuous operation are obtained, from where the limit and allowable values of the relative hourly combat losses of the equipment are found. Using this, the amount of equipment incapacitated only due to the fire impact on them from the enemy is found for future planning of the work of repair and restoration bodies. That is, knowing the expected value of the repair fund, it is possible to predict the performance of repair and restoration bodies taking into account the combat situation. The subject of further research may be the consideration of other factors affecting the performance of repair and restoration organs. This may be the training of personnel, the financial component, the use of depersonalized repair in the troops. Keywords: weapons and military equipment, reliability, repair and restoration bodies, mean time between failures, equipment ratio, enemy combat influence, limited technical reliability.
The article describes a possible version of a methodological approach to assessing the level of a unit's combat capability using indicators of its combat capabilities. Indicators of combat capabilities are the relative staffing of a unit, the relative level of training (learning) of personnel for the current amount of weapons, the relative staffing of the unit with weapons and military equipment (AME), and the relative staffing of the unit with expendable material and technical means (MTS). Given the absence of an analytical (formulaic) expression of the combat capability function, it becomes necessary to present the dependence of its level on certain indicators that affect this level. The current (which are determined during hostilities) values of the considered indicators, referred to their standard values, determine the corresponding level of the combat capability of the given unit. The difference between the standard and current values of a certain indicator is mainly due to losses during the fighting of the unit. The difference between the standard and current values of a certain indicator is mainly due to losses during the fighting of the unit. Based on the adopted definitions of indicators, as well as the definition of the combat capability of the unit under consideration, a dependence is proposed that determines the attainable level of combat capability of the unit. There is a definite connection between the indicators of combat capabilities. We consider not just the number of personnel (crews), but the number of trained (trained) personnel who are equipped with the available samples of weapons and military equipment of a certain type (group, type) of subunit. It is shown how, by varying these or those indicators within the permissible limits of their changes, it is possible to calculate the attainable level of combat capability of the unit under consideration, and, if necessary, of any military formation. Keywords: subunit combat effectiveness, combat capabilities, standard values of indicators, current values of indicators, manning, personnel, material and technical means, main armament.
Today, all samples of modern weapons and military equipment (OVT) have high requirements for readiness for combat use, reliable operation during combat. Due to the continuous improvement of the OVT troops and the enhancement of their combat capabilities, much attention is paid to the reliability of these samples, since failure to perform them due to the failure of the OVT can lead to serious consequences in the operation (combat). Therefore, for a more realistic description of the level of failure of a renewable and non-renewable sample of military equipment, it is necessary to select and substantiate a more adequate variant of the mathematical model, which will take into account the influence of most factors influencing the sample of technology. To describe the processes of equipment failure, under the assumptions defined in the article, it is proposed to use mathematical models of the type of queuing systems; This graph shows all possible transitions of this sample from one state to another, taking into account the specified operating conditions. The authors propose that, unlike what is actually observed in the military, the value of the probability of failure- free operation of a renewable sample should be presented as a non-renewable sample of weapons and military equipment. This is not the case with the definition of a non-renewable (not repaired) specimen, when this determination is no longer related to the type of specimen, its components (they can be repaired), not to the repair, but to the specific purpose of military equipment. Therefore, if during the combat work of a sample of equipment his failure occurred, then given the final and long enough recovery time after failure occurs, he is considered unable to perform the combat task. The main conclusion of the article is that, given the importance of military equipment, it is advisable to set them as a non-renewable sample of weapons and military equipment when substantiating the reliability of the design at the design stage. It can then be hoped that during the operation of the sample in the troops, the values of these indicators will be no worse than those recorded on the form, when weapons and military equipment are considered as a renewable sample.
