Modelling hydraulic regimes of pipeline systems using the theory of hydraulic circuits in the Internet

Along with a brief description of the main problems of pipeline systems (water, gas, heat, fire extinguishing), it is claimed that the energy and resource saving reserves available here can, to a large extent, be implemented through the rational organization of hydraulic operating modes using modern methods of mathematical and computer modelling. The paper reviews the software and computing complex of the new generation. The complex provides the possibility of remote application of effective methods for calculating modes. The principles of the complex implementation ensure the execution of calculations anytime, anywhere, and with any number of users with a connection to the global Internet and a standard web browser. The paper briefly outlines the technologies that form the basis of such complex, as well as its user capabilities and computational characteristics. Results of the pilot industrial operation of the complex are also described. The complex is potentially applicable in different industries (energy, housing and utilities, construction, etc.) and spheres of activity (design, operation, research, training). It would be also useful to the specialists of different levels (engineers, researchers, graduate students, etc.)
