Extended forecast of economic results: instrumental potential of the fuzzy sets theory
Статья научная
The article proposes an approach based on the fuzzy sets theory, in which the uncertainty, being originally a factor, hindering the adoption of grounded long-term management decisions, becomes a tool for their development. At that, the uncertainty of various data, characterizing the economic indicators of the process under study in the long run, is expressed by a single indicator using the modified method of the hierarchy analysis.

Modelling of economic systems with Petri nets
Статья научная
Modelling is one of the most important tools to study complex systems. Components of both continuous and discrete nature are present in the behavior of contemporary economic systems. The article uses formalism of nested hybrid Petri nets as a tool to study complex economic systems. The author describes basic approaches of simulation modelling, concepts of classical Petri nets, modified means of nested hybrid Petri nets, benefits of their use for systems modelling. The article presents the concept of a universal system of simulation modelling. On the basis of considered approaches the article proposes to develop a universal system of simulation modelling on the basis of the modified machine Petri nets.
