An analysis of science researches and production experience have shown that there is a need in the method of determining the number of vehicles and special technics for transport units in the pipeline industry. Decided to consider the system of transport and technological service of pipeline's repair processes as queuing system. A simulation method as a tool for determining the need of vehicles was chosen. The correlation between factors of primary production and the number of vehicles and special technics was determined.
