Abstract: This paper presents an approach for the joint optimization of maintenance and improvements of the components of a network of infrastructure facilities. In the literature, these two problems have often been handled separately, ...

Abstract: The development of models to predict the distribution of times between changes in condition-state for reinforced concrete bridge decks is presented in this paper. The authors used semiparametric hazard rate modeling ...

Abstract: In selecting the type of maintenance or rehabilitation (M&R) activity to apply to highway pavement sections, engineers rely on several items of information. Foremost among these is the effectiveness of the various M&R ...

Abstract: This paper presents an approach to address pavement management decision problems at airports with multiple runways. It relaxes some of the underlying assumptions made in previous studies and explicitly considers time ...

Abstract: In the context of sequential decision making under uncertainty, the Markov decision process (MDP) is a widely used mathematical framework. The MDP-based approaches in the infrastructure management literature can be broadly ...

Abstract: Bridge management problems are computationally difficult to solve when considering network connectivity, because all bridges must be analyzed together. Past research has usually adopted simulation-based numerical methods, ...

Abstract: System-level infrastructure management involves determining optimal maintenance, rehabilitation, and reconstruction activities for a system of facilities over a planning horizon to maximize the level of service subject to ...
