Models and algorithms of calculation of devices for damping pulsations of gaseous medium in pipeline systemsThe article presents the results of development of models and algorithms of calculation of technical devices intended to reduce the vibration impact of the working medium on the piping of reciprocating compressor units. Models differ in that they contain the information structure of a piston compressor, the working medium, the physical properties of gases and allow via algorithms presented in this article automate the calculation of the design characteristics buffer capacities and diaphragms smoothing the pulsation of the working medium. Using the developed models and algorithms will allow to reduce expenses on designing systems for pipeline binding of reciprocating compressor units and will contribute to improving the quality of their expert assessment in the period of operation.

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.

are given. It is shown that to eliminate disadvantage is possible using software packages, which
designed keeping in mind the methodology of system approach and methods of artificial intelligence
theory, modern concepts of integrated logistics support and integrated information environment. The
results of the systems analysis life cycle of pipeline systems are given. Engineering and technical setting
goals of integrated logistics support life cycle of pipeline systems of petrochemical companies
are Implemented. Presents a functional and hardware requirements for the complex of programs for
implementation of integrated logistics support. the architecture, the computational-network structure,
the composition of the database and description of functional modules of software complex programs
of integrated logistics support life cycle of pipeline systems of petrochemical companies a «Pipeline»
are given. The results of the practical application of the developed complex of programs «Pipeline»
on one of the Russian enterprises are given.
