An Analytic Toolbox for Optimizing Condition Based Maintenance (CBM) Decisions
Bibliographic record
Abstract
Condition-based maintenance (CBM) has evolved significantly with advancements in condition monitoring technologies and analytical methodologies. This paper presents a comprehensive analytical toolbox designed to optimize CBM decisions. The framework developed by Andrew K S Jardine and his research group at the University of Toronto, integrates classical statistical process control methods with modern proportional hazards models (PHM) to enhance predictive maintenance strategies. Economic considerations are integral to the CBM optimization process. By combining PHM with cost models, the EXAKT software tool, developed through collaborative research, enables the calculation of optimal maintenance actions that minimize total costs while maintaining equipment reliability. Case studies from industries such as pulp and paper, mining, and marine demonstrate the practical application and benefits of the CBM toolbox. These collaborations underscore the value of university-industry partnerships in advancing maintenance engineering research and practice.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
