Matteo Pozzi: Risk Analysis & Decision Making: Civil Infrastructure Systems


My name is Matteo Pozzi. I am assistant professor
in the Department of Civil and Environmental Engineering at Carnegie Mellon University. My research focuses on risk analysis and decision-making for civil infrastructure systems. Managers of infrastructure have to decide what information to collect, where to place sensors, when to schedule inspections. So, what I try to do, is develop approaches
for rational information gathering. One application of my research is related to wind farms maintanence.
We are investigating the use of micro-aerial vehicles for inspecting the turbines. By using these devices, we can collect relevant
information about the condition state of every turbine. But our specific task in this project
is to derive a priority list for understanding which components deserve more attention right now. Recently we started instrumenting the Scott
Hall building here on the CMU campus. We are installing fiber-optic strain sensors that
are very durable and precise devices that will allow us to follow in time what is the
behavior of the building in response to loads, to possible movement of the foundation, and
other information. This monitoring system will allow us to keep track of
risk associated with the building. Many infrastructure systems in the U.S. are aging, and their condition
is deteriorating. We have limited resources for taking care of the systems, and my research
potentially can guide decision makers toward an optimal allocation of these resources by
defining what component to inspect, how to process this data, and how to perform optimal
maintenance and potential replacement of these components.
