Modeling of managerial decision–making in the process of product sales and investment activity

Relevance of the research topic. The modern functioning of domestic entrepreneurship takes
place in an unfavorable external environment. For the first time, business encountered the necessity
of functioning in the conditions of martial law, which fundamentally changed the further development
trend of any enterprise. At the same time, a timely and effective management decision can reduce the
negative impact of the external environment on business. In this context, there is a need to deepen
the modeling procedure for making management decisions in the process of product realization and
investment activities.
Formulation of the problem. Every enterprise during any stage of the life cycle is faced with the
need to quickly make a management decision in accordance with current conditions. However, taking
into account the rapidity of scientific opinion and trends in the field of business, it is not always possible
to adapt already developed methods of making managerial decisions. Therefore, it is time to improve
the modeling of the management decision–making process using modern mathematical tools and its
adaptation in the practical sphere.
Setting goals and objectives of the study – to propose a model of managerial decision–making
in the process of product realization and investment activity.
Research method or methodology. In the process of determining the model of management
decision–making in the implementation of products and investment activities, we used the methods
of abstraction, induction, deduction, analysis, synthesis, modeling and the method of least squares.
During modeling, we also built regression models, calculated Fisher's and Student's tests.
Presentation of the main material (research results). Models of managerial decision–
making in the process of product realization and investment activities are proposed. As a result of
calculations using various methods, a forecast volume of sold products was obtained, which allows the
management to respond in time to negative changes and make the necessary decisions adequate to
the current situation.
Scope of the results. The proposed modeling can be used by all interested market stakeholders,
including civil servants, in order to make an adequate management decision and quickly react to
negative changes in the production or institutional environment.
Conclusions on the article. The stages of modeling and forecasting of the dependence of the volume
of sold products (goods, services) on capital investments are defined. The presented modeling allows
management to make management decisions depending on changes in the dynamics of the volume of
sales and capital investments. The conducted statistical analysis and forecasting using various methods
of linear and non–linear calculation of economic processes allows us to conclude that in real macro–
and micro environments it is possible to choose the most appropriate and effective method of making
management decisions based on external and internal factors influencing production.
