Heuristic computational tools the integrated logistic support of life cycle of pipeline systems of manufacturing enterprisesIt shows the influence of pipeline systems for reliability, cost-performance and industrial security
enterprises of the chemical industry and other industries. It shows the role of system maintenance
and repair, as well as integrated logistics support in ensuring the capacity for work of industrial piping
systems. The drawbacks of maintenance and integrated logistics support using disparate software
tools are shown. To eliminate these drawbacks authors offered of the approach to integrated logistic
support for the life cycle of pipeline systems of industrial enterprises based on the theory of artificial
intelligence, modern methods of mathematical modeling and logistics resource saving in the field
organization of production. Developed the following heuristic computational tools computerized integrated
logistics support industrial piping systems: logic and information life-cycle model of pipeline
systems, which mimics the procedure logistic support of piping systems, as complex organizational
and technological decision-making procedures; frame and productional models represent unformalized
knowledge about the technical and structural characteristics of the pipeline; heuristic-computing
algorithms of calculation of the technical and structural characteristics pipeline systems. Developed
heuristic-computing tools allow to automate integrated logistics support life cycle of pipeline systems
and to organize the interaction of all its subjects in a single information space.

Information-measuring system geographically remote locations in the gas transport sectorAlso in the gas industry introduced information-measuring system of gas distribution point. The
system provides data acquisition from geographically distributed points on the following parameters:
the gas pressure high or medium pressure at the inlet pipe, flow, pressure and temperature of the
gas dispensed to consumers, gassed object, control and emergency operation of unauthorized access
to the facility. Based on the results in the thesis organized serial production of a new generation
of cabinet distribution points at Novomoskovsk factory of «Elektrotsentrmontazh.»
Developed and implemented information-measuring system crane nodes, implemented with regard
to the crane in service nodes of the Moscow ring pipeline branch of «Gazpromregiongaz.» Implementation
of information-measuring system crane nodes allowed to increase security of supply
by the operation status control valve stations, which had previously been tested through periodic inspections
and removal of process parameters staff in manual mode. The validity of the use of GSMcommunication
due to the distribution valve stations over a large territory and the absence of any
other means of communication. In addition, the task was complicated by the fact that most of the
valve stations of the Moscow ring gas pipeline network has no power. This required the development
of intelligent information-measuring unit with a small power supply and solar powered.

Algorithms of multifractal image analysis of turbulent gas flows in pipelinesMethod and algorithm had been developed for analysis of amplitude-frequency characteristics of
turbulent compressible gas flows using the multifractal spectra. In multifractal analysis we used images
of hydrodynamic characteristics of gas flows that had been calculated by computer modeling. In
this case the «particles in cells» model had been used. The resulting images of hydrodynamic characteristics
were used to calculate Holder exponent. As a result of Holder exponent calculation we have
got so called α-images. These α-images were used further to calculate multifractal spectra. The calculations
were made for gas flows in the convergent tube. The multifractal spectra were used to calculate
generalized fractal dimensions, namely: fractal dimension, information dimension and correlation
dimension. It had been demonstrated that parabolic approximation of multifractal spectra is sufficient
to describe frequency characteristics of turbulent gas flows in the convergent tube. It had also
been proposed to use the correlation dimension as one of the frequency estimation criteria for turbulent
compressible gas flows in pipes.
