Abstract

It was found that with an increase in the normalized workmanship t0, the characteristic of failure distribution (flow characteristic) H_(i) (t_(0 )) increases, and this increase is more intense with low repair quality or the reduction factor of the average life between repairs of use (q), and with an increase in the level of quality (q) this intensity is significantly less, and with a constant coefficient of repair quality or the coefficient of reduction of the average inter- repair period of use (q), but with an increase in the values of b2 (coefficient of variation of new item fabrication) at a given normalized fabrication (t0) failure flow characteristic decreases.

Keywords
