ABSTRACT
ABSTRACT: National Cooperative Highway Research Program Project 12-67 has recently completed the development of a multi-objective optimization framework and decision support tool for bridge management. Designed to work with Pontis, a bridge management system offered by the AmericanAssociation of State Highway and Transportation Officials, the software is also adaptable to other bridge management systems containing suitable data
The new framework is distinctive in its ability to optimize bridge level and network level programs having multiple objectives and multiple constraints beyond life cycle cost. A utility function combines performance measures into a single objective function operating at both levels.
