Abstract

Reliable operation of complicated interdependent infrastructures, (including transportation, electric power, oil, gas, telecommunications and emergency services) is vital to developed economies. This paper develops a method to estimate the "time to recover" from a disruption in such interdependent infrastructures. It also develops a mathematical model and solution procedure to optimize investments in interconnected infrastructures to achieve improvements in "time to recover" subject to a budget constraint. These methods are illustrated on an example gas-electric infrastructure network
