Continuous improvement in predictive maintenance

It is commonly called the "Remaining Useful Life Estimate" or by the acronmym "RULE". One performance measure of a predictive maintenance program is the spread of the distribution around the mean (i.e. around the RULE). This spread  is quantified by the standard deviation.

  1. It is commonly called the "Remaining Useful Life Estimate" or by the acronmym "RULE". • One performance measure of a predictive maintenance program is the spread of the distribution around the mean (i.e. around the RULE). This spread  is quantified by the standard deviation. • Continuous improvement in the RULE occurs over time as more experience is gathered. Not only is the RULE adjusted, but the spread narrows. • And narrows further. • The RULE improves • Confidence in prediction increases in a measurable way so that it may be reported as a CBM KPI. RULE = Remaining useful life estimate Improving RULE Increasing confidence Continuous improvement in predictive maintenance Conditional MTBF Is the well-known MTBF, except that it is measured from the current moment. That is, the moment when one needs to make an on-condition maintenance decision. Conditional Density Function t0 Working age Current time
