Modern systems engineering infrastructure livelihood of a large city is a complex technical objects, which are characterized by an extremely high degree of branching, the set feedback and a very large territorial distribution. The fact that even a little effective control such a complex engineering system is impossible without the use of information technology – a fact "Granted" and has long been unchallenged. Means of computer technology and automation, as well as individual programs and even software systems in large quantities and for a long time more or less successfully employed in the services of virtually all major companies operating utilities to solve production problems. Ranging from bookkeeping, for which the era of the "paper" technology gone finally and irrevocably, and ending, for example, hydraulic calculations, without which the operation of heating systems at all impossible, and the water – very difficult. However, almost all without exception companies that operate networks of utilities, including even a "model", information on the whole suffers greatly from chronic industrial and system-wide "diseases". Development and exacerbation of these "Ailments" inevitably reduce the overall effectiveness of management leads to direct financial losses and an increased risk of accidents.
If you do not put the "correct diagnosis" and not "cure" these problems time, inevitable moment of transformation of Informatics and IT-technology from the tool to improve the reliability, quality and production efficiency in a serious brake or even collapse of the detonator in the process organizational and technological management. description of problems 1. Mismatch of information, the different software systems, each designed to solve a specific production problem, uses a certain set of data – both as a source of information, and as the generated result.
