Clipping Your Way to Predicting Failure: A New Approach Using Polygon-Shaped Health Indicators
This paper introduces RULCLIPPER, a novel prognostics algorithm using computational geometry and CBR to estimate remaining useful life (RUL) from imprecise health indicators (IHIs) represented as polygons. RULCLIPPER was evaluated on the NASA C-MAPSS turbofan engine simulator datasets, showing promising results in predicting RUL despite noisy data and varying operating conditions, with some limitations on data specific rules and IHI representation.
Possible Conflicts of Interest
None identified
Identified Weaknesses
Limited generalizability
The proposed RULCLIPPER algorithm relies on several rules and parameter choices specific to the C-MAPSS dataset, limiting its generalizability to other datasets or applications.
Limited applicability of IHI representation
The paper focuses on a specific type of health indicator (IHI) represented as a polygon, which may not be suitable for all PHM applications or data types.
Limited dataset diversity
The performance evaluation relies heavily on the C-MAPSS dataset, which, while comprehensive, may not fully represent real-world scenarios or diverse fault modes.
Rating Explanation
This paper presents a novel and interesting approach to failure prognostics using computational geometry and case-based reasoning. The methodology is well-described and evaluated on a comprehensive dataset. However, the reliance on dataset-specific rules and the limited applicability of the IHI representation are notable limitations.
