Abstract
Methods, systems, and computer program products for generating wear-based indicators for vehicular components are provided herein. A method includes assigning a failure class label to each data point, from multiple data points derived from measurements associated with a vehicular component across a fleet of vehicles, that is within a pre-specified number of runtime hours of a replacement; assigning a non-failure class label to each data point not within the pre-specified number of runtime hours of a replacement and each data point associated with a component yet to be replaced; estimating a failure probability at each data point over a pre-specified future runtime of the component based on the assigned class label; determining a cumulative hazard function for the vehicular component based on the failure probability; and generating a cumulative wear-based indicator for the vehicular component by executing a regression function at a given time based on the cumulative hazard function.
