摘要
It becomes a common practice to determi ne time for conducting preventive maintenance (PM) using a hazard function and an alarm limit on a specified failure rate. In this paper, the authors argue that u sing both hazard and reliability functions can improve the accuracy of the resul t, especially when the whole-life characteristic failure is modelled using diff erent failure distributions. The PM time predicted based on the hazard function should be checked against reliability.
