A Bayesian Approach to Condition Monitoring with Imperfect Inspections

Degradation is a common phenomenon for many products. Due to a variety of reasons, the degradation rates of units from the same population are often heterogeneous. In addition, when the degradation process is monitored using dedicated sensors, the measurements are often inaccurate due to various noisy factors. To account for the heterogeneous degradation rate and the non-negligible measurement ...

Finite element model updating of a geared rotor system using particle swarm optimization for condition monitoring

In this paper, condition monitoring of a geared rotor system using finite element (FE) model updating and particle swarm optimization (PSO) method is onsidered. For this purpose, employing experimental data from the geared rotor system, an updated FE model is obtained. The geared rotor system under study consists of two shafts, four bearings, and two gears. To get the experimental data,  iezoel...

Modelling of Condition Monitoring with Imperfect Inspections

The analytical modelling of a condition monitoring for a system which is subject to degradation over time is considered. The system condition can be observed at discrete times by means of imperfect inspections. In addition to the critical threshold, for each time point of inspection a replacement threshold is introduced. The decision rule when checking system suitability for use in the upcoming...

Three Models of Sequential Belief Updating on Uncertain Evidence

Jeffrey updating is a natural extension of Bayesian updating to cases where the evidence is uncertain. But, the resulting degrees of belief appear to be sensitive to the order in which the uncertain evidence is acquired, a rather un-Bayesian looking effect. This order dependence results from the way in which basic Jeffrey updating is usually extended to sequences of updates. The usual extension...
