    The subject matter of the article is the influence of operational-tactical and military - geographical factors of the combat area on the functioning of elements of the system for restoring armored weapons and military equipment during combat operations in modern conditions. The goal of the study is investigation of the correlation effects between operational - tactical and military-geographical factors of the combat area on the functioning of the armored weapons and military equipment recovery system. The tasks to be solved are: to analyze the influences of the factors of the combat area on the functioning of the system of restoration of armored weapons and military equipment during the performance of the Armed Forces missions by purpose; form formalsets of conditions and factors and elements and functional links of the system of armored weapons recovery and military equipment subject to their influence; calculate the factor loadings of each factor and construct correlation Pleiades of influence. General scientific and special methods of scientific knowledge are used. The method of hierarchy analysis, mathematical apparatus of probability theory and multidimensional statistical analysis were used. The following results are obtained. Operational-tactical and military-geographical factors of the area of operations and elements the functional relationships between the recovery system of armored weapons and military equipment are formally represented as sets of random variables, and the significance of each factor is expressed by the numerical value of the factor load. Based on the results of correlation and factor analysis, correlation Pleiades are constructed, which provide tools for algorithmic accounting of the essence and qualitative characteristics of the influence of factors in managing the renewal of armored weapons and military equipment. Conclusions. Operational-tactical and military-geographical factors for any region have an impact on the functioning of the system for restoring armored weapons and military equipment, different both in terms of semantic loads and the results of actions on individual elements of the system. Based on the results of factor analysis, the significance of the influence of each factor can be expressed asa numerical value of the factor load. The influence of both military-geographical and operational-tactical factors of the combat area and the quality of functioning of elements of the recovery system of armored weapons and military equipment correlate with each other. Correlation Pleiades of influence of military-geographical and operational-tactical factors of the combat area provide tools for managing the renewal of armored weapons and military equipment.

    The dynamic analysis of the state defense forces group logistics support system using of the queuing model
    (Національний технічний університет "Харківський політехнічний інститут", 2020) Sydorenko, Yevhen; Makogon, Helen; Isakov, Oleksandr; Korda, Mykyta; Mosiychuk, Mykhaylo; Klimov, Alexej
    A model of queuing is proposed to describe the logistics support process for the state defense forces group. In the model, the transitions of the sample of weapons from one state to another are carried out with intensities, μ or λ dependіs on the influence of the external environment and management. Within the framework of the proposed model, a differential equations system is obtaineddescribes the average numbers of weapons samplesin different states during their operation in the army. The obtained differential system solution corresponding the model is a quantitative estimate of the required number of weapons needed to ensure a given level of combat readiness and serviceability of state defense forcestroops, as well as optimal management of procurement, repair and modernization of weapons over certain time.

    Definition of residual operation resource of starter batteries by way of impedance research at different service terms
    (Національний технічний університет "Харківський політехнічний інститут", 2019) Makogon, Helen; Vasylenko, Denys; Potapov, Den; Piskun, Serghij; Bazilevskij, Igor; Ivanov, Vladimir; Klimov, Alexej; Prichina, Volodymir; Zobnin, Aleksej
    The subject matter of the article is the physicochemical processes occurring in a battery under different conditions and operating times. The goal of the study is to develop, a methodology for estimating the residual life-span of the batteries to make recommendations on the extension of their service life on the basis of an analysis of the conditions of use of the batteries. The tasks to be solved are: to analyze the influence of starter battery conditions on their performance and service life; to analyze the existing methods of determining the residual life of the batteries; to study the dependences of the deviation of the impedance fromthe standard value for the batteries at different moments of their normal life and to develop a method for predicting the residual life of the rechargeable batteries (RB). Generalscientific and special methods of scientific knowledge are used. The following results are obtained. On the basis of the readings of the ammeter and voltmeter when switching on the battariesin the circuit at different load values and according to the data obtained during the control-training cycle (CTC), the dependence of the impedance deviation from the base value at different regular battery life was investigated. According to the proposed method, it is easy to determine in which batteries the degradation has just begun and in which they have reached the level when they need tobe replaced without waiting for a fatal failure, by obtaining a minimum number of values of the electric parameters of the battery and comparing the data obtained at different times. Proper selection of chargers, skilled operation and timely monitoring of battary'sresidual life are the most important requirements for their operation. In full-time batteries, the internal resistance begins to increase over time due to natural wear and tear. Significant deviation from the norm in the smaller side indicates aclear malfunction sucha battery must be replaced regardless of its useful life. When the deviation from the baseline exceeds 25%, itis time to replace the battery. The conducted studies revealed nonlinear relationships between the battery life and its predicted residual life. Conclusions. Ensuring that the equipment is ready for use depends largely on the state of the RB. The greatest impact on the performance and life of the batteries is due to the temperature conditions, the degree of sparseness of thebatteries on the machine and the level of charging voltages on the network. In the actual operating conditions of the RB, there is a need to assess their technical condition, disassemble them for t oubleshooting, maintain their availability and extend their service life. RB degradation is reflected in the internal support of the battery cells. Determining the internal resistance of the RB is based on the Ohm dependencies of the complete circle and reduces to a system of two equations. RB life can be considered one of its most important performance characteristics. The relationship between battery life and itsestimated residual service life is nonlinear. Proper selection of chargers, skilled operation and timely monitoring of RB's residual life are the mostimportant requirements for their operation.
