The publication describes how the use of C4ISR architectures in the definition of requirements and analysis of complex systems provides for a conventional description of the domain and for detailed study of the processes in the investigated system. The steps and stages in the description of operational, systems, and technical views of the simulation system are presented. The requirements for the system’s software development are defined on that basis.</p>
