Abstract

In modern conditions of the Russian economy pipeline gas transportation is of particular importance. The most important task is to ensure the reliability and safety of gas supply while realizing the required system capacity. Meanwhile, Gazprom's gas transmission systems (GTS) are characterized by the aging of both the linear part and compressor stations, gas distribution stations and other auxiliary equipment under chronic underfunding of the system. In this regard, the reconstruction of the GTS of OAO “Gazprom”, in particular of OOO “Mostransgaz”, acquires crucial importance. The information model of GTS reconstruction proposed by the author is a multilevel graph. Each level is characterized by a certain set of investment projects, which are carried out during the practical implementation of the reconstruction. The selection of the most economically effective projects is a continuous sequential-reversal. There are several methods of calculation of objective criteria of economic efficiency of reconstruction projects of GTS: investment modeling of all available reconstruction projects; expert analysis and calculation of efficiency; analytical calculation of conditional efficiency of reconstruction projects (proposed by the author). In conditions of acute shortage of funds for financing HTS reconstruction projects, algorithms for selecting the most cost-effective projects can play a significant role, and the additional costs of their implementation are well repaid. When implementing optimization algorithms for selecting the most economically efficient GTS reconstruction projects, special attention should be paid to expertise.
