Applied aspects of modeling of information systems

The article is devoted to applied aspects of information modeling in the design of information systems of complex subject areas. It provides a logic diagram of the information system design and substantial description of the basic design stages. The article presents the hybrid cascaded-round-Robin algorithm of formation of a monitoring (monitoring, command, and control) information system. This algorithm is designed to compensate for the shortcomings of the cascade and iterative paradigms of design and to ensure the quality and viability of an information system in terms of short-term planning.
