Risk-Based Maintenance Optimization of Aging Highway Bridge Decks

Abstract: This paper presents a practical approach for maintenance optimization of a network of aging highway bridge decks that integrates a stochastic deterioration model based on Bogdanoff's cumulative damage theory with an effective multi-objective optimization approach. The multi-objective maintenance optimization takes into account all relevant objectives, such as improving bridge deck condition, minimizing maintenance costs, and minimizing traffic disruption and associated user costs. The consideration of these th… Show more

“…For this reason, maintenance plans should be prepared and bridges should be evaluated according to various criteria. Some of these criteria in literature include but not limited to the condition state of bridge, average daily traffic, maintenance cost, and user cost [4], [ 5]. The first three criteria are used in this study and the bridges are prioritized based on these criteria.…”

“…The criterion used in compromise programming is the minimization of the deviation from the ideal solution (f*) measured by the family of (L p ) metrics (Koski 1984;Lounis and Cohn 1993). In this paper, a multi-criteria optimality index introduced by Lounis (2004), "MOI", is defined as the value of the weighted and normalized deviation from the ideal solution (f*) measured by the family of (L p ) metrics:…”

“…Examples are those proposed by Lounis and Vanier (1998), Fwa et al (2000), and Lounis (2004). These studies presented the application of multi-criteria optimization to prioritize networks of bridges or pavements for maintenance according to several and possibly conflicting criteria, such as risk of failure, cost, and traffic disruption.…”

“…Over the last decade, reliability-based optimal design of buried pipe distribution systems has been studied by several researchers and this has resulted in the development of a number of reliability models and the application of optimization techniques (Rahman and Vanier 2004). Different optimization approaches have been implemented in different buried pipe management systems ranging from simplified economic models to advanced Markovian decision processes (Lounis 2006).…”
