Abstract:

Models to support maintenance and rehabilitation for infrastructure systems rely on the specification of a ``perfect'' deterioration model. In this context, inadequate characterizations of facility performance can lead to the implementation of inefficient policies. These inadequacies can be caused by (unobserved) heterogeneities or model uncertainty. In this paper, the authors present a probabilistic, model-based framework where deterioration is represented by a finite-mixture of pre-specified models. The framework proves an effective approach to manage facilities while clustering them based on their observed deterioration. The authors present numerical examples to illustrate the method.
