Engineer Receives NSF Grant To Improve Manufacturing

Yong Chen, assistant professor of mechanical and industrial engineering and researcher in the Center for Computer Aided Design (CCAD) in the University of Iowa College of Engineering, has received a three-year, $199,987 National Science Foundation (NSF) grant to help improve manufacturing quality and productivity.

Chen will serve as the project principal investigator in an investigation of the reliability of variation source sensor systems used in manufacturing. Chen says that reliability modeling of such sensor systems is essential to improving manufacturing quality and productivity. "The purpose of my grant is to model, evaluate and optimize reliability of complex sensor systems in their design phase. It can be applied to areas such as manufacturing, navigation and military surveillance to significantly reduce the risk of mis-detection and false alarms caused by sensor system failures."

According to Chen, Rockwell Collins and the UI Power Plant are interested in implementing the developed techniques generated in the research. His future research plan is to establish sensor system reliability and fault-tolerance improvement methodologies for both design and in-field usage of sensor systems to keep pace with ever-growing sensor technology.

Chen received his master's degree in statistics and doctorate in industrial and operations engineering from the University of Michigan in 2003. His fields of knowledge in statistics, operations research and manufacturing lend themselves to his research interests including sensor system reliability modeling and optimization and robust manufacturing process monitoring and diagnosis.
