dc.description.abstract[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In this thesis, a methodology to fortify a transportation network by allocating resources for maintenance of critical structures (e.g., bridges and tunnels) is developed in order to minimize the economic impact of network disruption caused by structure failures. In the network vulnerability assessment literature, component-specific vulnerability indices (sometimes referred to as criticality indices) are usually derived by considering the change in network performance in the absence of one of its components. Because such metrics consider only the failure of one component at a time, they cannot entirely capture how the network would function if multiple components failed simultaneously. To address this issue, scenario-based method is proposed to minimize the expected economic cost of simultaneous failures that will be accrued within a certain time period by allocating limited maintenance resources across various structures. Here, the expected economic costs of simultaneous failures capture the cost of decrease in network performance (measured as total flow times) and network disconnectivity as a single cost measure. It is assumed that failure probabilities of structures are known before and after a maintenance activity and that all origin-destination (O-D) flows to the arcs in the transportation network are optimally assigned once a failure scenario is realized.eng
