| Summary: | Background. Modern conditions of warfare have tightened the requirements for the completeness of
information support for the management of combat operations and, as a result, the time requirements for aviation systems
as suppliers of information about the enemy in the information networks of the command and control systems
have expanded. In order to minimize the losses of personnel in combat operations, as well as to automate the processes
of performing tasks, unmanned aerial vehicles (UAVs) are used, combined into groups of UAVs for the successful
implementation of a flight task in conditions of differentiation of each aircraft according to its leading function. The
use of such a group of UAVs in the course of performing heterogeneous tasks for their intended purpose requires an
assessment of efficiency and quality in the conditions of information technology impact, taking into account the time
spent on predicting the outcome of events formed as a result of the course of all stages of the process of functioning by
a group of UAVs, which allows to obtain statistical data on the time of its course. Such a process includes: analysis,
generalization and decision-making with the required measurement accuracy and the minimum required number of
experiments while maintaining the statistical reliability of the experimental results. The purpose of the scientific article
is to develop a methodology for assessing the efficiency of the decision support system (DSS), which is placed simultaneously
on board the leading UAV leader and at the ground flight control station in order to synchronize the operator's
actions with the autonomous behavior of the grouping in the air. The introduction of such a system into the general
control cycle leads to an increase in the efficiency of the "UAV-leader – operator" system and reduces the time
spent on completing the task for its intended purpose by parallelizing the processes of collecting and processing information
flowing in the system circuit. The use of a high-speed special calculator in the UAV control system makes it
possible to optimize computational costs and implement highly efficient algorithms embedded on board. Materials
and methods. Based on the physical interpretation of the considered task of reducing the time indicator, taking into account
various factors affecting the result of the overall solution, the equity method is used, which establishes the share
of the influence of various factors on the effectiveness of the proposed methodology. The criterion for evaluating the
effectiveness of the technique under consideration is efficiency, and the indicator is the time spent on completing the
flight task. Results. The article presents the results of systematization and analysis of the information processed by the
DSS on board the leading UAV, as well as calculations of the efficiency indicator of the proposed methodology and
their comparison with existing ones. Conclusions. Based on the physical interpretation of the considered task of reducing
time indicators, taking into account various factors affecting the result of the overall solution (based on the study
of the equity method), the share of influence of each indicator on the effectiveness of the proposed methodology is established.
