4. Ignoring industry-specific engineering network is fundamentally different from any other spatially distributed systems in that it describes a special concept – "Mathematics graph. This is A network of nodes and connecting branches, rather than a set of isolated objects. Most of the information-computing tasks for network engineering can be solved without special tools mathematical description of the graph. A vivid example of neglect of this circumstance is use of so-called "geographic information systems (GIS) utility to create a graphical representation of the network and related databases. gis utility, as a rule, do not contain a "built" a special instrument for solving problems on graphs, and therefore the possibility of beneficial use is severely restricted.
Omission this circumstance, the purchase and implementation of very expensive gis subsequently leads to an almost insoluble contradiction between the principle laid down in the gis – the picture to the content, and the principle of construction of the majority of applications industry, which is the exact opposite – "from the process description – a graphical representation. * On the sectoral specificity of information technology for the utilities we a lot and wrote at length, beginning in 1997, the key of these publications – 'AR Eksaev. City Engineering Networks and problems of information, or to co-create Hottabych phone ', August 2000 – is absolutely relevant in its core today. addressing company itc 'Flow' offers technology to consistently eliminate these problems and obtain direct and synergistic effect of integrated solutions operational objectives of enterprises utilities – heating systems, water utilities, gas distribution networks, electricity grids.
