The scientific and technical basis of the computer-aided analysis, optimization methods and techniques
to ensure the structural and parametrical reliability of energy and resource saving Complex Gas
Supply Pipeline Systems (CGSPS) are generalized and developed. The methodology for support and
optimizing the performance reliability of CGSPS is presented. Оriginal techniques for engineering and
technological failure analysis of facilities and complex gas pipelines, forcasting, reliability diagnostics
and troubleshooting the causes of CGSPS are developed. New engineering techniques to ensure
the reliability and safety of CGSPS systems are proposed. The technique for construction and practical
application of the original topological (graph) models of gas supply pipeline systems reliability is
briefly stated. On the basis of these models original methods of reliability factors calculating, including
a qualitative analysis method of «the reliability of gas supply pipeline system topology» and decomposition
methods of reliability multi-criteria optimization for CGSPS, are developed. Special program
complexes for calculation and optimization of reliability, security risk management, integrated
logistic support of gas pipelines and facilities of CGSPS, environmental monitoring and CGSPS impact
assessment on the environment are developed.
