Abstract
This talk addresses the latest model-based approaches to the design of engineered complex systems with reduced cost, risk of failures, and development time. Systems such as state-of-the-art aircraft, advanced power systems, unmanned aerial vehicles, and autonomous automobiles, are required to operate dependably in a variety of environmental conditions, over a wide range of missions. They often exhibit complex forms of failure and are by nature difficult to model and analyze. Unknown emergent interactions between subsystems, which might be independently managed and engineered in isolation of other subsystems, make these systems unpredictable until they are tested in operation. Though they undergo rigorous testing and validation, highly publicized, costly, and sometimes fatal accidents still occur, usually preceded by multiple seemingly innocuous events that cascade across subsystems.  The grounding of the Boeing 787 line (estimated to cost $5 billion) and the Deep Water Horizon disaster (incredible economic, environmental, and human cost) demonstrate the dangers of addressing complex interactions too late.
 
As engineered systems have increased in complexity over the years, the prediction and mitigation of faults has become a more difficult task, requiring the use of improved methodologies to be applied as early as possible at the design stage. Furthermore, when such systems are designed, multiple design teams are typically involved, where each team is responsible for the design of a subsystem, and different trade-offs are required between many design teams before all the subsystems can be implemented in the final systems. Model-based system design offers a means of rapid evaluation and redesign with the overall goal of reduced risk of failures, design time and effort in such design environments.  
 
About the Speaker
Dr. Irem Y. Tumer is the Associate Dean for Research and Economic Development for the College of Engineering, and a Professor in the School of Mechanical, Industrial, and Manufacturing Engineering at Oregon State University, where she leads the Complex Engineered System Design Group in the Design Engineering Laboratory. Her research at Oregon State University (2007-2016) has attracted funding from NSF, AFSOR, DARPA, NASA, industry, and private foundations, with a total funding of over $6M, and has resulted in nearly 50 journal publications and over 100 refereed conference publications to date, 9 PhD students, and 15 MS students. Prior to coming to OSU, she led the Complex Systems Design and Engineering group in the Intelligent Systems Division at NASA Ames Research Center (1998-2006), where she worked as Research Scientist, Group Lead, Deputy Area Lead, and as a Program Manager, leading programs up to $8M/yr.
 
Dr. Tumer has been Conference Chair for ASME’s Design for Manufacturing and the Lifecycle conference in 2000, Program Chair for IEEE Reliability Society’s Prognostics and Health Management Conference in 2008, and Program Chair (2011) and Conference Chair (2012) for ASME’s International Design Theory and Methodology Conference; Associate Editor for ASME Journal of Mechanical Design, and the International Journal of Prognostics and Health Management, and guest editor for AEIDAM journal’s special issue for Design of Complex Engineered Systems, and is on the Editorial Board of various journals. 
 
As Associate Dean for Research and Economic Development for the College of Engineering at Oregon State University (since 2013), she pursues large center initiatives, leads the establishment of industry and national lab collaborations, mentors assistant professors and supports faculty in research development.  Her efforts as Associate Dean have resulted in increasing the number of proposal submissions by 60%, doubling the amount of research funding awarded, increasing the research expenditures by nearly 20% to $40M, and increasing the number of NSF early CAREER awards six-fold last year from the yearly average over the past 5 years.  She received her Ph.D. in Mechanical Engineering from The University of Texas at Austin in 1998. She is a member of ASME, ASEE, SWE, and past member of IEEE, SME.
