Abstract :
The relationship between failure rate and technical condition parameters of equipment was established through the Weibull proportional hazard model (WPHM). The dynamic decision-making model of the test intervals for condition based maintenance was formulated with failure risk as restriction. The validity of the model was verified using oil spectral analysis data of an engine.
