The relevance of the topic. The most effective approach to studying and forecasting intersectoral economic relations is to use models that are modified versions of well-known input-output balance models. The methodological aspect is to develop a new model that is a modification of the existing semi-dynamic input-output balance model. Purpose. The analysis of existing models and plans, as well as the process of digitalization of the company's economic development, confirms the need to create a comprehensive model. This model should take into account the dependence of income and expenses on product tariffs, as well as the elasticity of demand for services and the impact of tariffs on the prices of consumed resources, which is determined by the structure of intersectoral relations. Methodology. To achieve the research objectives, complex methods were used, including a systematic analysis of existing simulation models designed for operational management of the company, as well as mathematical modeling methods. Results and conclusions. The research results formed the basis for creating a model that visualizes the distribution of products in three key areas: meeting current production needs, financing capital investments in the creation of production assets, and final consumption. The model has a three-block structure, where each block is closely connected to the others. The first block is responsible for the balance of production and distribution of products. The second block covers the balances of enterprises' income and expenses, as well as the algorithms for profit distribution. The third block models the process of transforming production investments into new capacities and describes the dynamics of fixed assets and production potential. Scope of application. Research results can serve as a basis for constructing and modernizing the methodological apparatus of operational management in modern corporations.

The relevance of the topic. Due to various crisis situations in the activities of companies, various kinds of problems arise that have to be solved both strategically and operationally. Methodological problems lie in the choice of a set of effective methods and digital tools that allow for the scientific solution of specific management issues. Goal. Analysis of existing modeling, planning processes and creation of an automated system of planned calculations at different levels of economic management of the company using simulation models that take into account such parameters as: a set of technological measures used in the production of a specific type of product; quantitative parameters, as well as the resulting indicators, both for specific types of work and for the entire production time interval. Methodology. The study was carried out using methods of logical and comparative analysis of existing simulation models of operational management of the company, as well as methods of mathematical modeling. Results and conclusions. As a result of the conducted research, algorithms were built to determine the indicators of the technological component of the production of products. In the constructed model, a significant part of the analysis of results and decision-making are the function of a team of specialists or, according to common terminology, an expert. The developed simulation model contributes to strengthening the economic justification of planned indicators, ensuring storage and automated search of the company's regulatory framework, and its periodic updating. The scope of application. The results of the research can be used in the development and updating of methodological tools for the operational management of a modern company.
