The article is written on a highly topical issue related to improving the efficiency of the logistics support system operability. The purpose of the article is to improve the technique for evaluating the efficiency of the logistics support system of the combined arms force under conditions of combat actions.
The essence of the technique, that determines its novelty, is to take into account the possibility of substantiating indicators and criteria for evaluating the survivability of the logistics support system and their impact on the efficiency of the system operability as a whole through employment of existing models for evaluating the survivability of logistics support subsystem under conditions of combat actions.

1. INTRODUCTION.
One of the components of the sustained and reliable combined arms force logistics support system oper-ability under conditions of combat actions is the surviv-ability of the logistics support units.
The issue of evaluating the survivability of logistics support units holds a prominent place under conditions of combat actions. This is due to the fact that the
success of combat actions is achieved mainly by destroying military objects and facilities, which include: personnel;
command and control centers; combat and transport equipment; logistic stocks and other objects. Formulation of the problem. Analyzing the course of the Joint Forces operation, local wars and
modern armed conflicts, it can be noted that special attention is paid to the issues of damage to the facilities of logistics support units. This is due to the fact that the logistical support of troops (forces) is considered one of the main factors in the implementation of the combat mission [1-3].
Analysis of recent research and publications. In the scientific research, one cannot but pay attention to the scientific works of O. Vorobiov, I. Vlasov, O. Ugri-novich and others, who quite deeply reveal most of the issues of this range of problems [4].
The purpose of the article. To improve the technique for evaluating the efficiency of the logistics support system of the combined arms force under conditions of combat actions.
2. RESEARCH RESULTS
2.1. The boundaries and object of the technique. The improved technique can be used by the relevant officials when making decisions concerning accomplishing tasks by logistics support units of the combined arms force under conditions of combat actions. The variant of evaluation of the logistics support subsystem survivability will be the object of the technique.
2.2. The purpose of the technique. To evaluate the efficiency of the combined arms force logistics support system operability based on the indicators of the logistics support subsystem survivability and its functions restoration efficiency under conditions of combat actions [5].
THE ESSENCE IMPLEMENTATION IMPLEMENTATION STAGES:
STAGE 1. Determination of the evaluated indicators.
When determining the resulting survivability indicator of the logistics support subsystem, which is studied, it is advisable to take into account the generally accepted military term "survivability of the system".
To construct a two-part indicator:
the first part should be the indicator of the degree for preservation of the logistics support subsystem functions during combat actions of the adversary force;
the second part of the survivability indicator (in case of non-preservation of the logistics support subsystem functions during combat actions of the adversary force) should be the indicator of the degree for restoration of the logistics support subsystem functions.
Thus, the first component of the survivability indicator has the meaning of the indicator of stability functions preservation during combat actions of the adversary force, and the second - the indicator of functions restoration in case of damage by the enemy of any logistics support subsystem components of the combined arms force under conditions of combat actions.
STAGE 2. Determination of the generalized minimax indicators of logistics subsystem survivability preservation applying existing models of survivability evaluation.
Uncertainties of an antagonistic nature when assessing the level of survivability preservation of the logistics subsystem (with ammunition, petroleum prod-
ucts and lubricants, as well as other means) of the combined arms force under conditions of combat actions necessitates the application of the criterion of evaluation the guaranteed level of survivability indicator to achieve the assigned goal.
The criterion will facilitate obtaining of a guaranteed evaluation of the assigned goal achievement level of maintaining the survivability of the logistics support subsystem (with ammunition, petroleum products and lubricants, as well as other means) under conditions of combat actions. This criterion is based on application of the minimax technique of overcoming uncertainty of random and antagonistic type [5].
STAGE 3. Determination of the criterion of generalized efficiency evaluation of the logistics complex subsystem operability.
A fundamental condition for increasing the logistics support subsystem survivability is a significant reduction in the average time for replenishment of combined arms force units with ammunition, petroleum products and lubricants,
and a significant reduction in time for recovering the means of management, compared with the average time necessary for these components of the logistics support subsystem to solve the problems of support being combat ready for use,
that is, it is necessary to significantly increase the average time for the main components of logistics support (with ammunition, petroleum products, lubricants and other means) to be on combat-ready alert.
In quantitative terms, the goal of the successful operation of the logistics support subsystem is to reduce the average time to replenish or restore the relevant stocks to a level commensurate with the average period of sustainable operation of this support subsystem under conditions of combat actions.
Similar approaches are used to evaluate the effectiveness of the logistics support subsystem in conditions of damage and restoration of command and management facilities, weapons and automotive equipment, taking into account losses, costs and replenishment of ammunition, petroleum products, lubricants and other means.
The probabilistic model of this complex subsystem of logistics support of the combined arms force under conditions of combat actions should be evaluated using the given indicator of operational efficiency, but to solve a more complex problem.
First, it is advisable to consider the possibility of ensuring the actions of troops (forces), in case of combining several traditional types of support (replenishment of ammunition, petroleum products and lubricants, military equipment, military uniforms and accessories, food supplies and other material resources) in an integrated logistics support system.
Secondly, it is necessary to finally quantify the unsatisfactory level of the combined arms force support under conditions of combat actions, in case of consistent solution of support tasks, for example, in case of lack of necessary forces and means of support in the studied system in order to provide simultaneous actions of the combined arms force under conditions of combat.
OF THE TECHNIQUE IS IN THE OF THE FOLLOWING
3. CONCLUSIONS AND PROSPECTS OF FURTHER RESEARCH
The essence of the improved technique for evaluating the effectiveness of the combined arms force logistics support system, which determines its novelty, is to take into account possibilities of substantiation of indicators and the criteria for survivability evaluation of the logistics support system and their impact on the system operability efficiency as a whole due to the use of existing models for evaluation of the logistics support subsystem survivability under conditions of combat actions.
The improved technique makes it possible to determine the conditions for increasing the efficiency of logistics support management and improving the logistics support subsystem of the combined arms force under conditions of combat actions.

Введение. В разных машинах и механизмах вращательное движение передается от одного вала к другому по-разному. Если расстояние между валами относительно велико, то вращательное движение передается ремнем или цепью. В зубчатых передачах вращательное движение передается с помощью шестерен, которые образуются за счет
взаимодействия зубьев. Удлинители шестерен очень распространены в машинах. Шестерни используются для передачи вращательного движения от приводного вала к ведущему валу. Шестерни также широко используются в различных частях автомобиля, в основном в суставах, передающих движение.
