Multiple-Objective Optimization for Bridge Management Systems

Currently available bridge management system (BMS) tools compute an optimal solution based on the objective of least long-term cost. Bridge managers are finding that their constituents require bridge conditions to be substantially better than a least long-term cost solution would provide. Research is needed to develop a multiple-objective optimization model. Two distinct BMS models are needed: a network-optimization model and a bridge-level model. The network model will provide a decision-making tool that optimizes bridge actions for multiple performance criteria. These performance criteria could be cost, condition, risk, Highway Bridge Replacement and Rehabilitation (HBRR) program eligibility, Bridge Health Index, or others. The bridge-level model will evaluate the effect of bridge action alternatives on life-cycle cost and other performance criteria for the purpose of selecting projects that are consistent with the network goals. Both models will use the AASHTO BridgeWare database supplemented with additional data as needed. Commonly Recognized (CoRe) Elements data shall be used for condition assessments. The bridge-level model should consider recommendations from the network-level model. In addition, the network model should be capable of considering projects selected within the bridge-level model. Nevertheless, these models should be capable of operating independently. Both models should explicitly consider the inherent uncertainties of estimated costs and outcomes. The objectives of this project are to develop methodologies and to produce a BMS software module for network- and project-level optimization of multiple, user-specified performance criteria.
