Abstract:

Reversed hazard rate (RHR) is a useful tool in the area of maintenance management, particularly for condition monitoring. Its typical behaviour makes it suitable for the assessment of waiting time and hidden failures. Nature of reversed hazard rate is therefore, analytically and numerically investigated, for the standard distributions and presented in this paper. It is shown that RHR is a decreasing function for important statistical distributions, which rather makes it viable to be used in the field of maintenance engineering. Required data was simulated in MATLAB version 7.0. The results are discussed and presented in the paper.
