Talk Title: Control of Dynamic Systems with Multiple Objectives
Abstract: The challenges of controlling multiple dynamic systems with multiple objectives include problems in multi-player dynamic games, multi-objective optimization, and decentralized control and estimation. The additional complexities are caused by the existence of non linearities, time delays and perturbations in dynamic models, as well as various state, input and communication constraints. In this talk, a number of results related to multi-objective control of multiple dynamic systems will be presented. To illustrate these results some particular examples of controlling multiple dynamical systems in pursuit of accomplishing multiple objectives such as guaranteed capture or evasion, collision avoidance, tracking, and coverage control, will be presented.
Biography: Dr. Dusan Stipanovic received his B.S. degree in electrical engineering from the University of Belgrade, Belgrade, Serbia, in 1994, and the M.S.E.E. and Ph.D. degrees (under supervision of Professor Dragoslav Siljak) in electrical engineering from Santa Clara University, Santa Clara, California, in 1996 and 2000, respectively. Dr. Stipanovic had been an Adjunct Lecturer and Research Associate with the Department of Electrical Engineering at Santa Clara University (1998-2001), and a Research Associate in Professor Claire Tomlin's Hybrid Systems Laboratory of the Department of Aeronautics and Astronautics at Stanford University (2001-2004). In 2004 he joined the University of Illinois at Urbana-Champaign where he is now Associate Professor in the Department of Industrial and Enterprise Systems Engineering and Coordinated Science Laboratory. He is a visiting Professor in the School of Electrical Engineering, University of Belgrade, Serbia, and in the Robotics and Telematics Department at the University of Wuerzburg, Germany, and also held a visiting faculty position in the EECS Department at the University of California at Berkeley. His research interests include decentralized control and estimation, stability theory, optimal control, and dynamic games with applications in control of autonomous vehicles, circuits, and medical robotics. Dr. Stipanovic served as an Associate Editor on the Editorial Boards of the IEEE Transactions on Circuits and Systems I and II. Currently he is an Associate Editor for Journal of Optimization Theory and Applications.

Talk Title: A Mathematical Modeling Framework to Personalize Mammography Screening Decisions
Abstract: Breast cancer is the most common non-skin cancer and the second leading cause of cancer-death in US women. Although mammography is the most effective modality for breast cancer diagnosis, it has several potential risks, including high false positive rates, which are not very rare. Therefore, the balance of benefits and risks, which depend on personal characteristics, is critical in designing a mammography screening schedule. In contrast to prior research and existing guidelines which consider population-based screening recommendations, we propose a personalized mammography screening policy based on the prior screening history and personal risk characteristics of women.
We formulate a finite-horizon partially observable Markov decision process (POMDP) model for this problem. Our POMDP model incorporates two methods of detection (self or screen), age-specific unobservable disease progression, and age-specific mammography test characteristics. We use a validated micro-simulation model based on real data in estimating the parameters and solve this POMDP model optimally for individual patients. Our results show that our proposed personalized screening schedules outperform the existing guidelines with respect to the total expected quality-adjusted life years, while significantly decreasing the number of mammograms. We further find that the mammography screening threshold risk increases with age. We derive several structural properties of the model, including the sufficiency conditions that ensure the existence of a control-limit policy.
Biography: Dr. Oguzhan Alagoz is currently an Associate Professor of Industrial and Systems Engineering at the University of Wisconsin-Madison. He received his BS from Bilkent University in 1997, MS from Middle East Technical University in 2000, and PhD in industrial engineering from the University of Pittsburgh in 2004. He worked as a visiting assistant professor of Operations at the Weatherhead School of Management of Case Western Reserve University between 2004 and 2005. His research interests include stochastic optimization, medical decision making, completely and partially observable Markov decision processes, simulation, risk-prediction modeling, health technology assessment, and scheduling. He is on the editorial boards of Operations Research, IIE Transactions, and IIE Transactions on Healthcare Engineering and previously served on the board of Medical Decision Making. He has received various awards including a CAREER award from National Science Foundation (NSF), outstanding young industrial engineer in education award from IIE, Dantzig Dissertation Honorable Mention Award from INFORMS, 2nd place award from INFORMS Junior Faculty Interest Group best paper competition, best paper award from INFORMS Service Science Section, and best poster award from UW Carbone Comprehensive Cancer Center. He has been the principal investigator and co-investigator on grants more than $3.5 million funded by NSF and NIH.
