Predictive Maintenance with Weibull Curves

Starting with failure event data (time, distance or time, event string), this demo fits a parametric failure model with a Weibull curve distribution. The Weibull parameters indicate whether failure hazard is decreasing (burn-in failure) or increasing (normal wear-out failures).

Using expected costs for routine maintenance versus more expensive costs of an unplanned failure, optimal maintenance intervals are computed to ensure operational excellence.
