  • Managing the amount of harmful substances in the atmosphere

    One of the most important problems of our time is the excessive emission of carbon dioxide into the atmosphere. The article proposes a mathematical model of the system for monitoring the emission of carbon dioxide into the atmosphere. The model is two-level hierarchically organized. Industrial enterprises act as a lower-level subject of management, and the state or its authorized body acts as a top-level subject. All subjects of management of the lower level seek only to maximize their gain. The main goal of the upper level entity is to maintain the quality of atmospheric air within the specified range. The problem is considered in a game setting. The Stackelberg equilibrium is constructed. The construction algorithm is specified, and it is programmatically implemented. An analysis of the obtained results is given, a number of conclusions are made about the optimal strategies of all participants in the system, based on the results obtained in the course of applying the Stackelberg algorithm.

  • Simulation of optimal management of the national park activities

    The continually increasing rate of human economic activity leads to changes in many natural systems. Their restoration is one of the most important tasks today. For this purpose, protected areas have been created, such as natural reserves, national parks, and wildlife sanctuaries. National parks are of particular interest, as they are the only protected areas listed above where tourism is allowed and organized. However, their activities cannot exist without sufficient financial support. This article describes a two-level optimal control model of the national park activity. For the purpose of exploring and analysing the proposed model, an algorithm that can be used to find the Stackelberg equilibrium guaranteeing the sustainable development of the national park is proposed and implemented in software.

  • Simulation of the interaction between a retail enterprise and a commercial bank

    The development of the construction industry leads to an increase in small businesses both in construction and in the sale of building materials. Besides, small business fills the market with various goods, solves various social and economic issues such as unemployment, industry monopoly. However, its activity can't exist without sufficient financial support. A two-level mathematical model of interaction between a retail enterprise and a commercial bank as a funding structure is considered. To research the proposed model, the method of simulation modeling based on numerical search was used. A computer program was created to build a Stackelberg equilibrium algorithm with hierarchical control as an impulsion. The algorithm can be used to find the optimal values of the control parameters of an individual entrepreneur and a commercial bank. These values maximize the objective functions and profit of the system participants. The identification of the proposed model was carried out on the basis of data obtained from the Internet. Finally, the results were obtained using numerical examples.A number of conclusions could be made about the functioning of the entire system.
