Journal ArticleDOI
Optimal replacement policy and the structure of software for condition‐based maintenance
TL;DR: In this paper, the authors present a preventive maintenance policy based on inspections and a proportional hazards modelling approach with time-dependent covariates to analyse failure-time data statistically, and present the structure of the software, currently under develop and supported by the CBM Project Consortium.
Journal ArticleDOI
Optimal Bayesian fault prediction scheme for a partially observable system subject to random failure
TL;DR: A new method for predicting failures of a partially observable system is presented, which is illustrated using real data obtained from spectrometric analysis of oil samples collected from transmission units of heavy hauler trucks used in mining industry.
Journal ArticleDOI
Autoregressive model-based gear shaft fault diagnosis using the Kolmogorov–Smirnov test
Xiyang Wang,Viliam Makis +1 more
TL;DR: In this paper, an autoregressive model-based technique is proposed to detect the occurrence and advancement of gear shaft cracks, which is used as a linear prediction filter to process the future signal.
Journal Article
Multivariate Bayesian control chart
TL;DR: Under standard operating and cost assumptions, it is proved that a control limit policy is optimal, and an algorithm is presented to find the optimal control limit and the minimum average cost.
Journal ArticleDOI
A note on optimal replacement policy under general repair
Viliam Makis,Andrew K.S. Jardine +1 more
TL;DR: The form of the optimal replacement policy is found and the expected average cost per unit time is derived which can be minimized to obtain the optimal replacements time.
