Prof. de Weck is a leader in systems engineering research. He focuses on how complex man-made systems such as aircraft, spacecraft, automobiles, printers, and critical infrastructures are designed and how they evolve over time. His main emphasis is on strategic properties that have the potential to maximize lifecycle value (a.k.a the “iIities”). Since 2001 his group has developed novel quantitative methods and tools that explicitly consider manufacturability, flexibility, commonality, and sustainability among other characteristics. Significant results include the Adaptive Weighted Sum (AWS) method for resolving tradeoffs amongst multiple objectives, Time-Expanded Decision Networks (TDN), the Delta-Design Structure Matrix (DDSM) for technology infusion analysis and the SpaceNet and CityNet simulation environment. These methods have impacted complex systems in space exploration (NASA, JPL), oil, and gas exploration (BP) as well as in sophisticated electro-mechanical products (e.g. Xerox, Pratt & Whitney, DARPA). Prof. de Weck’s teaching emphasizes excellence, innovation, and bridging of theory and practice.
