A simple condition monitoring model
for a direct monitoring process

Christer, AH; Wang, W

Abstract

This paper addresses the problem of condition monitoring of a component which has available a measure of
condition called wear. Wear accumulates over time and monitoring inspections are performed at chosen times to
monitor and measure the cumulative wear. If past measurements of wear are available up to the present, and the component is still active, the decision problem is to choose an appropriate time for the next inspection based upon the condition information obtained to date. A simple model which minimizes the expected cost per unit time over
the time interval between the current inspection and the next inspection time is derived, and numerical examples are
given to demonstrate the solution method.
