Abstract
Example implementations described herein are directed to systems and methods for estimating the remaining useful life of a component or equipment through the application of models for deriving functions that can express the remaining useful life over time. In an aspect, the failure acceleration time point is determined for a given type of component, and a function is derived based on the application of models on the failure acceleration time point.

A method, comprising:
- processing first sensor data for a plurality of first components of a first type of component to determine a failure acceleration time point, the failure acceleration time point indicative of an inflection time point of failure acceleration for the first type of component;
- deriving a function for defining remaining useful life for the first type of component based on the failure acceleration time point;
- and
- for receipt of second sensor data of a second component being the first type of component, applying the function to the second sensor data to determine the remaining useful life of the second component.
An apparatus, comprising:
- a processor, configured to:
- process first sensor data for a plurality of first components of a first type of component to determine a failure acceleration time point, the failure acceleration time point indicative of an inflection time point of failure acceleration for the first type of component;
- derive a function for defining remaining useful life for the first type of component based on the failure acceleration time point;
- and
- for receipt of second sensor data of a second component being the first type of component, apply the function to the second sensor data to determine the remaining useful life of the second component.
A non-transitory computer readable medium, storing instructions for executing a process, the instructions comprising:
- processing first sensor data for a plurality of first components of a first type of component to determine a failure acceleration time point, the failure acceleration time point indicative of an inflection time point of failure acceleration for the first type of component;
- deriving a function for defining remaining useful life for the first type of component based on the failure acceleration time point;
- and
- for receipt of second sensor data of a second component being the first type of component, applying the function to the second sensor data to determine the remaining useful life of the second component.
