Modeling of the system of monitoring and analysis of information of electronic media by methods of model based system engineering

When developing any information system, an extremely important stage of its life cycle is the design or modeling stage. Among the existing approaches to the design of information systems, such as, for example, the “classic” development of UML diagrams using a unified modeling language, the model-oriented systems engineering approach, focused on building models, is gaining popularity. Purpose of the study. Consider modeling a system for monitoring and analyzing electronic media information using the methods of model-oriented system engineering. Research methods and tools. It is proposed to use the toolkit of the system-oriented design methodology, focused on the creation and use of models of different degrees of detail at different stages of design. The application of models of hierarchical decomposition of entities is presented on the example of typical essential characteristics of artificial systems: requirements for the system, system functions, system components (subsystems), work on creating a system. A regular method for constructing and consistently expanding architectural models of products is described, on the basis of which models of hierarchical taxonomy of functional requirements for the system, key functions, and components of the system core are built. Based on hierarchical taxonomy models, a model for matching requirements and functions and a model for matching functions and system components are built. Results. The developed models clearly show the relationship of system components, requirements, functions and modules with each other. The approach used makes it possible to detail the presentation of the system based on its decomposition into subsystems and on the basis of taking into account the essential characteristics. All this makes it possible to streamline the sequence of stages of creating a system and decompose them into separate stages of work. Conclusion. The results obtained in the course of the conducted research make it possible to proceed to the next stage of the life cycle of the information system being developed - its software development.
