Survival Regression for Cost-Optimal Maintenance of Wearing-Parts under Various Operating Conditions
Wednesday, October 5, 2022
Estimating lifetime of a machine or a wearing-part in a complex machine is a requirement in cost-optimal maintenance planning to reduce costly downtime or avoid too frequent maintenance. Regression models mapping features to the time-to-failure are not suited in the real world because of censored data. This talk shows how survival regressions can be utilized for a maintenance planning application. We discuss and demonstrate available survival analysis tools, their strengths and limitations.
