The article describes the system model with adjustable parameters and its mathematical analysis. The model allows us to investigate the conditions of achieving economic equilibrium and to consider possible states of the system in this context. In the model, the economic system is described by the interaction of three components: the producer, the aggregate consumer, and the price regulator. The manufacturer produces two types of products (goods), and its production capacity limits their maximum

... output. The specific value of production volumes of each type of product is determined by the producer himself, based on current prices. Having fixed specific output volumes, the producer transfers the goods to the domestic market. The consumer, having received this supply, forms the volumes of demand from his side. In this case, the model takes into account the level of prices and preferences of the consumer. Depending on the ratio of supply and demand, products are sold in the model. Volumes of money, which were not covered by supply, are transferred and accumulated in the "unsatisfied supply" fund. Volumes of goods, which were not consumed, are accumulated in the "deferred demand" fund. According to the results, the model proposes to change the value of prices, if necessary, to introduce a coefficient of price adjustment, after which the process is repeated under new conditions. After a certain number of iterations based on the results of the model, it is possible to obtain the state of the system as well as the history of its formation. This allows us to make a conclusion about the correctness of the pricing strategy and evaluate the obtained results. The described model is implemented as a component of a distance course. The use of computer modeling tools, in combination with e-learning tools, has confirmed their high efficiency.
