value required by the consumer at the moment, and is reduced to the capacity of the main gas pipeline in order to give priority to large consumers. The results of the calculations, presented in the form of graphs in Figure 1, allow us to state that the reduction of the gas supply reliability coefficient brings the extremum of the objective function closer to the region of priority consumers, which corresponds to real ideas about service optimization.

4. Conclusions Thus, on the basis of the analysis of possible failures and damages on the objects of the linear part and the technology of preventive and repair and restoration works, a modular and technological structure of the repair and operation unit was formed. A computer-oriented method of assessing the maintainability of the linear part of the main gas pipeline has been developed. Partial problems of choosing work technology and rational assembly and equipment of technological modules with various resource limitations have been solved. References Buslenko, N.P., 1977.
