In a modern society, civil infrastructure facilities in different systems depend upon each other for product input and/or information sharing. Thus, understanding such dependencies and properly modeling them is essential to assess the performance of the civil infrastructure systems during and following a disruptive event, which lays the foundation of assessing the community resilience. This paper introduces the Dynamic Integrated Network model which is developed to assess the damage and recovery of the network of all considered systems following a disaster by considering the facility-level dependencies. A hypothetical study region consisting of electric power, potable water and cellular systems under a scenario hurricane is used to demonstrate the proposed model. A comparative study is performed with the case when inter-system dependency is ignored. This study confirms the importance of incorporating the inter-system dependencies to improve the estimation on the recovery process.
