This paper discusses a procedure for determining the optimal period of preventive replacement of elements with increasing failure rate when the criterion is income per operating time unit.It is shown that income per operating time unit and its complementary value of the sum of losses due to system jolly rancher filled gummies dwell and replacement costs represent more general optimization criteria than minimal replacement costs and maximal availability; they also represent only separated cases of both complementary criteria.This property is suggested to be applied in technical systems without a dehued income per operating time unit by introducing the coefficient of correct operation importance (availability) in relation to replacement costs as a compromising criterion The expressions read more for equivalent parameters of reliability of elements with increasing failure rate are derived which enables the analysis of reliability and availability of technical systems with these elements in the conditions of the re-established process of their preventive replacement.The realized software program gives numerical values of all parameters for all optimization criteria.
