In the research paper, the descriptive and comparative methods were used. The paper presents general overview of the importance of the graph theory and nets. The authors underline that it is a crucial issue for many areas of science. Scientific interest in networks has a long tradition and is associated with the emergence of graph theory in mathematics. Another area of research for graphs and networks is social network analysis.

Regardless of organizational and legal conditions, enterprises become participants in so-called logistics networks.
