Abstract:The conventional method to optimize maintenance is by analyzing failure data and then model this with a probability distribution. The company Loodswezen wants to optimize their maintenance (intervals) but does not have the data that is needed for this. The solution in this case is a Bayesian based expert elicitation method in which experts "create" the necessary information. A statistician is then able to convert this information to a probability distribution, in this case the Weibull distribution. The Weibull distribution can then be used to optimize maintenance/replacement intervals. In this case, the optimal maintenance interval is designed such that the total downtime of the vessels of Loodswezen is minimized. This is done by the use of a simple age maintenance method which can easily be extended with more sophisticated methods to schedule maintenance.
