Annotation:
The article considers the main approaches to the analysis and synthesis of the complex main gas transportation systems (GTS). It is shown that the GTS decomposition depth is related to the formulation of the tasks to be solved and depends on the algorithms and computational procedures for modeling the corresponding regime-technological tasks. The possibility of using neural network models to calculate the operating characteristics of GTS elements is determined. Two possible approaches to the synthesis of neural network models of the complex GTS are proposed.
