AN APPLICATION FOR COMPUTING FAILURE AND SURVIVAL RATES OF AUTO COMPONENTS

Nirbhay Pherwani, Kunal Tolani

Abstract


An application for computing failure of automobile components using Weibull and other survival analysis methods is presented through this paper. The following areas are touched upon: I) Failure rates are described first, along with data cleaning and ‘failed’ data is defined within spell periods; II) Kaplan-Meier life curves are used to compare the failure mode reliability over time; III) Vehicle failure is analyzed by applying Weibull regression to fit on real-world data from different conditions.

Keywords


Weibull model, Kaplan-Meier life curve, Survival Estimation
