For modelling economic systems, it has been proposed to use a model of formal structure systems, which has the property of formal system, algebra and structure (composition). An example of the modelling of a bookkeeping system has been considered.

For modeling economic systems with two conditions, it is offered to use the nonlinear variable dynamic model with two conventional conditions «demand» and «proposal». It is demonstrated that the points of balance, limiting cycles and relaxation variations... see more

In the article an actual scientific and practical problem of complex economic systems integration modelling was settled and solved, in which a complex economic and mathematical models of the creation process’ of integrative structures of various shapes, w... see more

The enterprise as an economic system at the micro level is characterized by uncertainty in situations when making decisions, a large number of input indicators, as well as the presence of a decision maker of information that is poorly formalized and canno... see more

Worldwide, demand for water, energy, and food are on the rise due to population and industrial growth. Because of such increasing demands and in spite of the limitedness of key resources, more efficient ways to meet these demands become obligatory. Especi... see more

The article deals with the relevant scientific and practical task – assessing the effectiveness of various types of existing systems by methods of mathematical modeling. In particular, the research investigates the efficiency of functioning of social and ... see more

Integrated energy-economic modelling is needed to support the development of energy and climate policies. This study asserts that it is important to consider a system dynamics modelling approach that includes dynamics, endogenous treatment of uncertainty ... see more

The contribution of mining activities to social infrastructure and human development is a complex socio-economic development issue in South Africa. Complexity theory has introduced a new approach to solving problems in social systems, recognising them as ... see more
