Abstract
Within the framework of the article, the goal was to increase the design process efficiency and analyze complex systems by setting and formalizing the system analysis task for complex system contextual modeling. The research relevance is justified by the steady growth of both used and developed production technologies in the Russian Federation over the past five years, which directly indicates an increase in the complexity level of modern technical and information solutions. In accordance with the purpose, the research structure included the subsequent solution of the main tasks: the formulation of the system analysis task for complex system contextual modeling (formulation of the task short name, potential user description, frequency of solutions, approaches to solving the problem, task type, conditions of applicability, task features, requirements for the result, initial data, expected results); formalization of the system analysis task for complex system contextual modeling (the designation nomenclature description, model type, assumptions, limitations, formalized foundations of the model). The applied research methods were system analysis, functional modeling and comparative analysis of information system design tools. The results obtained include a formalized model of the contextual modeling process, identified problem areas of traditional contextual modeling technology and a proposal for a single tool that bridges the information gap between system requirements and its model. The research novelty lies in the fact that the integration of requirements management and contextual modeling functions in a single software tool can significantly reduce labor costs, increase the accuracy and consistency of system analysis results and ensure model dynamic updating when changing the external or internal operating conditions of complex systems.
