Dr. Irem Y. Tumer, ASME Fellow, is a Professor in Mechanical, Industrial, and Manufacturing Engineering at Oregon State University, where she leads the Complex Engineered System Design Group. Her research focuses on the overall problem of designing highly complex and integrated engineering systems with reduced risk of failures, and developing formal methodologies and approaches for complex system design and analysis. Since moving to Oregon State University in 2006, her funding has largely been through NSF, AFOSR, DARPA, and NASA. 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, Group Lead, and Program Manager.  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;  and is current  Associate Editor  for  ASME Journal of Mechanical Design and  the International Journal  of  Prognostics  and  Health  Management, and guest editor for AEIDAM journal.  She received her Ph.D. in Mechanical Engineering from The University of Texas at Austin in 1998.

The mission of the Complex Engineered Systems Design Group within the Design Engineering Labs 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

Example research interests include:

  • 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
  • Mulitiagent  based design of multidisciplinary engineered systems
  • Network analysis based vulnerability identification
