There is a growing awareness in recent years that the interdependencies among the civil infrastructure systems have significant economic, security and engineering implications that may influence their resiliency, efficiency and effectiveness. Zhang and Peeta propose a generalized modeling framework that combines a multilayer infrastructure network (MIN) concept and a market-based economic approach using the computable general equilibrium (CGE) theory and its spatial extension (SCGE) to formulate the static equilibrium infrastructure interdependencies problem. This paper extends the framework to address the dynamic and disequilibrium aspects of infrastructure interdependencies problems. It briefly reviews the static equilibrium modeling framework, and proposes a multi-period dynamic MINSCGE model that explicitly considers the evolution of infrastructure interdependencies over time and the temporal interactions among the various systems through dynamic parameters that link the different time periods. Using this model, numerical experiments for a special case with a single region are conducted to demonstrate the ability of the modeling framework in formulating and solving practical problems such as cascading failures, disaster recovery, and budget allocation involving multiple infrastructure systems in a dynamic setting.

The DVD lists the title of this paper as: Multiperiod Dynamic Model for Analyzing Infrastructure Interdependencies.
