RATIONAL ACCOMMODATION OF REPAIR AND OPERATING UNITS FOR MAINTENANCE OF MAIN PIPELINES

The task of increase of operating reliability of the gas-transport system is examined due to the rational placing of repair-operating subsections in the region of maintenance of gas pipelines. The increase of amount and closeness of placing of repair subsections in the region of maintenance of gas pipelines will allow to shorten time of lead through of restoration works in the case of origin of refuse on linear part of gas pipeline from one side, and will result in the increase of charges on their maintenance from other. Therefore dependence of charges on exploitation of the gas-transport system as a function of parameters of its reliability must have extreme. The mathematical model of forming of optimum chart of placing of repair-operating subsections is built in the region of maintenance of gas pipelines, which allows to optimize the process of service which will promote reliability of exploitation of the gas-transport system.
