The mission of the Complex Engineered Systems Design Laboratory is to develop mathematical frameworks to understand, analyze, model, and design complex and integrated engineered systems that include hardware and software. A common theme in the ongoing CESD Lab research is the concept of failures and the system-level risks and uncertainty associated with failures, a desire to enable the designers of such complex hardware-software systems to meet the stringent robustness, reliability, and safety requirements by developing processes and tools for Systems EngineeringModel-Based Design, and Risk-Informed Design

Ongoing research interests include (see projects):

  • Risk and Failure informed design for software-hardware systems
  • System-level analysis of complex engineered systems
  • Design of Prognostics and Health Management (PHM) Systems
  • Systems requirements development for software-hardware system design and reuse
  • Uncertainty analysis and modeling in large organizations
  • Function based modeling and analysis
  • Verification of complex systems
  • Analysis of connectivity and modularity in complex systems
  • Robust optimization and mitigation of cascading failures

The details of ongoing research projects can be found in projects. See feature story on our DARPA funded work in Digital Design of Complex Systems.

    Dr. Irem Tumer joined the Design group in 2006 in Mechanical Engineering at Oregon State University. Her research focuses on the overall problem of designing highly complex and integrated systems with reduced risk of failures, developing formal methodologies and mathematical frameworks to help understand and enhance complex system design. Her expertise touches on systems engineering, model-based design, risk-based design, system analysis and optimization, function-based design, integrated systems health management, vibration monitoring, which has resulted in numerous journal and refereed conference publications (see Publications.) Prior to accepting a faculty position at OSU, Dr. Tumer led the Complex Systems Design and Engineering group in the Intelligent Systems Division at NASA Ames Research Center, where she worked from 1998 through 2006 as Research Scientist and Group Lead, and was involved in Project/Program management in various NASA Programs including Intelligent Systems, Engineering for Complex Systems, Aviation Safety, and the Constellation Programs. She received her Ph.D. in Mechanical Engineering from The University of Texas at Austin in 1998. She is past Technical Program Chair of IEEE Reliability Society's First Annual Prognostics and Health Management Conference (2008), and Symposium Chair for Integrated Systems Engineering at the ASME Computers and Information in Engineering Conference (2008). She is past Technical Program Chair (2001) and Conference Chair (2002) for ASME's Design for Manufacturing and the Lifecycle Conference, and past Program Chair for the ASME International Design Theory and Methodology Conference (2011) and Conference Chair for the same conference (2012). She is Associate Editor of ASME's Journal of Mechanical Systems, Guest Editor for AIEDAM's Special Issue in Complex System Design, and has been Guest Editor of JMD's Special Issue on Design under Uncertainty, and past Associate Editor of the Journal of Prognostics and Health Management. She is currently Associate Dean for Research and Economic Development for the College of Engineering at Oregon State University.
