Abstract: A system for determining a decrease in service life to a target component is provided. The system includes a service life modeling (SLM) computing device, which identifies a physics variable for a test component. The SLM computing device generates a likelihood function for the physics variable. The SLM computing device applies probabilistic techniques to the physical measurements together with a set of coefficients. The SLM computing device generates a hybrid service life model for the test component. The SLM computing device calibrates the hybrid service life model. The SLM computing device applies the hybrid service life model to a target component that shares characteristics with the test component. The SLM computing device identifies a predictive metric for the target component. The SLM computing device outputs the metric. The SLM computing device directs an operator to modify a maintenance plan for the target component based on the metric.
