| Abstract | This paper presents a new approach for the maintenance optimization of concrete bridgedecks, which combines a stochastic deterioration model and a multi-criteria optimizationmodel. The stochastic deterioration model is based on the first-order Markov chain thatpredicts the probabilistic time-variation of the condition of bridge decks. The multicriteriaoptimization model takes into account two important and conflicting criteria: theminimization of maintenance costs, and the maximization of the network condition. Thisapproach generates the solution that achieves the best compromise between thesecompeting criteria, while considering the uncertainty in bridge deck deterioration. Thefeasibility and capability of the proposed approach is demonstrated on a network ofbridge decks obtained from the Ministère des Transports du Québec database. Thisexample illustrates the effectiveness of the proposed approach in determining theoptimal set of maintenance alternatives for reinforced concrete bridge decks whenconsidering two or more relevant optimization criteria. |
