As a result of the conducted research, the structure of production workers professional-qualifying staff forming system at cars repair was identified. Interaction regularities of the system elements were determined. The obtained results allow creating an imitating model for production workers professional-qualifying staff optimization. That model lets disclose regularities of various factors’ influence on production workers professional-qualifying staff of maintenance and repair areas of transport enterprises. The imitating model was created as a computer software. The practical use of the obtained results helps decrease the expenses on staff training and loss caused by insufficient qualification of repair workers.

In the article, the problem of reliability ensuring of bulldozers working at oil and gas objects bases backfill is considered. Typical failures are revealed. Statistical data on time between failures of bulldozers’ elements are obtained. Time between failures distribution regularities of running gear elements and engine are determined. Adequacy of logarithmic normal law of distribution and Weibull’s law is proved. Directions of the received results use are offered.
