Description: The search for optimal methods of using forces and means of border guard units is studied on the basis of modelling the stabilization actions in the context of military crisis situations. The main difference of actions of the units of the State Border Guard Service of Ukraine in such conditions are the ways of fulfilling tasks. It is the definition of operation method that is the basis of the concept for the use of units (elements of service and combat order) and represents the main problem of the activities of command echelons in the decision-making process. When choosing a method of operation, there is a need to resolve the con-tradiction between the need to maximize the impact on the enemy and the capabilities of the elements of the service and fighting order on the exercise of this influence. The solution to this contradiction depends on a large number of conditions and factors, which simultaneously are difficult to consider without the use of the appropriate scientific and methodical apparatus. The flexi-bility in the choice of methods of action and their constant change are peculiarities of the stabilization actions which also must be taken into account during their modelling. Considering the above-mentioned contradictions and the peculiarities of stabiliza-tion actions, the operation methods of the units of the State Border Guard Service of Ukraine in stabilization actions were deter-mined to be the subject of the research. The purpose of the research was to improve the quality of the decisions on the unit de-ployment of the State Border Guard Service of Ukraine in stabilization actions by developing a model for choosing methods to perform tasks in stabilization actions in the context of military crisis situations. The basis of the developed model is the analysis of the methods for carrying out tasks and assessment of their priority taking into account the capabilities of the border guard units, the anticipated actions of the enemy and other conditions and factors that determine the achievement of the goal of stabili-zation actions. The research resulted in the development of a model for choosing the methods of operation or the border guard units, which is based on a combination of possibilities of the method of hierarchy analysis and methods of the game theory. The hierarchy analysis method enables to evaluate the priority of the method for task execution which is interpreted as the probability of its application, the choice of operation methods is carried out with the use of the game method, depending on the action variants of the enemy. Unlike existing models, the priority of the method of operation is determined by the indicator of complete capability use of units (elements of service and fighting order). The developed model ensures the effective use of the capabilities of the elements of service and fighting order and enables to increase the efficiency of task execution in the conditions of resource constraints due to the optimal choice of methods of operation. The model can be applied in the decision-making support system for the deployment of units of various organizations and elements of service and fighting order while planning the stabilization actions.
