Abstract:
Integrity, robustness, reliability, and resiliency of infrastructure networks are vital to the economy,

security and well-being of any country. Faced with threats caused by natural and man-made hazards,

transportation infrastructure network management must be directed towards: (1) understanding the

network performance as a system; (2) modeling the dynamic interaction between the network and the

external and internal demands; and (3) defining hazard management strategies to optimize resource

allocation. The objective of the project is to develop a model of infrastructure transportation network

that can be used to design efficient risk management strategies to ensure an acceptable performance

(e.g., in terms of expected damage or recovery times) when subject to the action of individual,

simultaneous, or sequential hazards. This study explores the performance of infrastructure networks

using a systems approach. This approach is different from most existing modeling techniques in that

networks will not be modeled as a collection of separate elements, but rather as a dynamic structured

functional unit. This project develops new analytical methods built on a hierarchical

structure of the system, which directs the analysis to the interaction and dependencies between

components. This are used to characterize and model the emergent properties of the entire system.

The performance of the network is integrated with the analysis of individual network components.

Time-dependent models will be used for studying the life-cycle performance (mechanical and

operational) of network components (e.g., bridges) and to maximize the objective performance

function (e.g., cost or efficiency of the response) for different time windows. The case of the

transportation network of Texas is used as an illustrative example of some parts of the model.
