Samer Madanat is the Xenel Distinguished Professor, Chair of the Department of Civil &Environmental Engineering, and the Director of the Institute of Transportation Studies at the University of California at Berkeley.

He received a B.Sc. in Civil Engineering from the University of Jordan in 1986, and a M.S and Ph.D. in Transportation Systems from MIT in 1988 and 1991 respectively.

His research and teaching interests are in the area of Transportation and infrastructure Management, with an emphasis on modeling facility performance, the development of optimal management policies under uncertainty, and the integration of sustainability considerations in the transportation management process.

In 2000, he received the Science and Technology grant from the University of California Office of the President.From 2001 to 2010, he served as the Editor-in-Chief of the ASCE Journal of Infrastructure Systems. He is a member of the editorial board of several technical journals.

主讲内容简介：

Samer Madanat will present an adaptive optimization approach, known as Open-Loop Feedback Control (OLFC), for Maintenance, Repair and Replacement planning of systems of bridge components. The proposed implementation of OLFC in Bridge Management Systems is intended to improve bridge management decision-making and deterioration model learning. To illustrate the desirability of this approach, we consider a planning agency managing a system of facilities with limited prior knowledge of the deterioration models over a designated planning horizon. We show that OLFC improves model accuracy and reduces system costs, with a demonstration of how to incorporate system budget constraints when the system is heterogeneous. We focus our discussion on bridge decks, the component of bridge structures that undergoes the fastest deterioration, but the methodology is applicable to all bridge components.
