Application of Fuzzy Logic Methods to Evaluate the Serviceability of Northern Main Pipelines | Chapter 4 | Fundamental Research and Application of Physical Science Vol. 4

 The paper presents the influence of of or in the atmosphere conditions of the North on the utility of trunk pipelines (TP) of the North, including: thermokarst, lump, soil erosion, solifluction, obstruct, presence of secret ice, ice composition and related negative processes. Such influences bring about the fact that in harsh climatic conditions the passage transport is exposed to differing deformations to a much greater magnitude and higher necessities should be imposed on fabrics, structures and laying sciences.More than 65% of the trunk pipelines (TP) in the North are produced through swamps, watered areas and frozen water soils. The annual amplitude of air hotness fluctuations in these fields ranges from 80 to 90 degrees. This leads to unpredictable changes in relating to space displacement and deformations of passage networks, reducing the dependability and safety of technical schemes by 2-3.5 times. The question of increasing the dependability and safety of TP is especially appropriate for the northern domains, where, at intensely cold temperatures in cold, gas is one of the main beginnings of energy for heat supply structures. To improve dependability and reduce damage from the possibility of danger situations, it should to determine the risk elements, identify vulnerabilities, decide the main parameters for cultivating measures to reduce the risk, lighten the material and financial consequences as long as of an emergency. Due to the a lot of uncertainties in the complete data used, it is projected to solve this intensely complex but necessary task utilizing fuzzy models joining qualitative expert knowledge and determinable statistical arrangements.
