Development of a methodological approach to the research of special purpose communication systems

As a result of Russian aggression against Ukraine, some fundamental theses regarding the nature of hybrid military operations will require clarification and even revision. First of all, this refers to the widespread perception of the asymmetric nature of hybrid threats as those used by a weaker adversary against a party with significantly greater military, technological and human potential, mainly by non-state actors against national states. This, in turn, requires the use of modern and proven mathematical apparatus, which is capable of processing a large array of various types of data in a short period of time with a given reliability of making management decisions. The object of research is the system of strategic management of national security. The subject of the research is the synthesis methodology of the intellectual system of strategic management of national security. The research developed a methodology for the synthesis of an intelligent national security management system. The novelty of the research: taking into account efficiency while choosing one or another method while researching the state of the national security system; calculation of reliability while choosing one or another method in researching the state of the national security system. Also, an element of novelty is taking into account the efficiency of the decisions made regarding the research of the state of the national security system while using one or another research method; adaptation to new challenges and threats to national security. The next element of novelty is the validity of management decisions in the management of the national security system; taking into account different data sources, which are different in origin and measurement units; analysis of large data sets. It is expedient to implement the specified methodology in algorithmic and program software while studying the state of the national security system.
