The article is devoted to the search for new, more efficient tools and methods of model based system design and analysis. The field of the research includes functional modeling being the source of target system functional properties in the conditions in which it operates. System modeling is defined as using virtual analogues instead of physical things, which under certain assumptions and simplifications have properties similar to the material system. Within the framework of this study, the problem of reducing the functional complexity of entire target system to a certain number of simpler functions is solved, the analysis and synthesis of which fits within the capabilities of available mathematical methods and computing tools. To solve this problem, we propose a general abstract metamodel of system functions, the connections of its parts, as well as a theory that alows “disassembling” and “assembling” system models into its individual semantic parts, while functional integrity is kept. The aim of this research is to increase the effectiveness and to reduce R&D time of critical technologies and systems using a modern national system engineering platform
