Abstract: The subject of the study is a scientific and methodological apparatus for evaluating the effectiveness of systems for countering robotic complexes. The object of research is a scientific and methodological apparatus for analyzing systems for countering robotic complexes at important facilities. The aim of the work is to develop a scientific and methodological apparatus for evaluating the effectiveness of systems for countering robotic complexes at important facilities in the direction of taking into account their structure, spatial configuration, as well as the synergetic effect of the joint use of heterogeneous technical means as part of the system. In order to achieve the research goal, the general logical-probabilistic modeling method and the tools of modern geoinformation systems are comprehensively applied in the work. The article proposes a new approach to evaluating the effectiveness of spatially distributed multi-bridge systems for countering robotic complexes. The results obtained can be used by interested organizations to evaluate the effectiveness of variants of such systems and identify their vulnerabilities. The scientific novelty consists in the development of an approach to assessing the effectiveness of spatially distributed multi-border systems for countering robotic complexes, taking into account their structure, spatial configuration, as well as the synergetic effect of the joint use of heterogeneous technical means of countering robotic complexes through the integrated use of new logical-probabilistic models and modern geoinformation technologies. The results obtained in the article indicate that the goal of the work has been achieved.
