Post-Earthquake Lifeline Service Restoration Modeling

In this study, a simulation-based methodology is being developed to model post-earthquake restoration processes of lifelines as part of the MCEER research on Los Angeles Department of Water and Power’s (LADWP’s) electric and water supply systems. Post-earthquake restoration models play an important role in estimating the economic impact of earthquake damage to lifeline systems. This paper begins with a discussion of the available restoration modeling approaches, listing advantages and disadvantages of each. The new simulation-based methodology is described, and key innovations that distinguish it from previous approaches are explained. Finally, plans for possible future extensions are discussed.
