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.

Abstract: The subject of the study is a scientific and methodological apparatus for designing systems of physical protection of objects that ensure the detection of items made of non-standard materials prohibited from being brought into the protected area. The object of the study is the process of detecting weapons made of polymer materials using special technical means. The aim of the work is to develop the scientific and methodological apparatus for designing systems of physical protection of objects in the direction of updating the models of violators due to the systematic presentation of methods of unauthorized passage of weapons made of polymer materials. The methods of system analysis are used in the work. The authors note the possibility of using 3D weapons as a new means of implementing security threats to objects. In the interests of countering such threats, research is being conducted on the introduction of terahertz (sub-terahertz) personal inspection complexes that detect objects made of non-standard materials hidden under clothing on the body of the object of inspection, as well as determining the main methods of concealed 3D weapons to create adequate models of violators necessary for the design of new and improvement of existing systems of physical protection of objects. The paper presents the characteristics and results of a comparative analysis of the main methods of concealed carrying of such weapons. In conclusion, it is noted that the identification of 3D weapons is complicated by the fact that the details can be modified to make it difficult for security personnel, operators of complexes at the inspection point and machine vision tools to recognize them. The results of the study can be used during the design of physical protection systems for objects that ensure the detection of prohibited items made of non-standard materials. The scientific novelty of the work consists in the development of a scientific and methodological apparatus for designing systems of physical protection of objects by developing intruder models that take into account the methods of concealed carrying of weapons made of polymer materials.
