Abstract

The objective of technical condition assessment of the system of gas distribution pipelines is to obtain reliable information concerning the technical condition of the particular sites of the distribution system for successful planning of their maintenance and repair works, as well as for taking decisions on the extension of the operation time, reconstruction or elimination. The developed methodology provides for the development of the indices describing the sites of the system of gas distribution pipelines - the base factor (Fij), the share of the score set for each factor (Вij) in the group of the factor shares (βi), the shares of the group (ai), based upon which, by means of applying the linear algorithm, the group calculation score (Bi) and the integral score (F) are set and according to these scores the technical condition of the particular site is assessed and the conditions for its further operation are defined.
