摘要：Conceptual design is an early and critical phase of the engineering design process. Decisions made in the conceptual design phase can affect dominantly the final product cost. Therefore, having good concepts at the end of this phase is one of the important factors to successful actions. This requires effective and efficient methods and tools that can help designers deliver innovative and creative solutions. To build such methods and tools, it is indispensable to discover the knowledge about design activities such as the nature of design, factors affecting design activities and the designer’s mental process. This work is a continuing effort to build a science of design which aims to discover knowledge about design activities through formal scientific process. In this talk, we will focus on a new design theory that has been developed based on two postulates:
· Postulate of recursive design reasoning: Design reasoning follows a recursive reasoning process.
· Postulate of designer’s stress-creativity relation: Design creativity is related to designer’s mental stress through an inverse U shaped curve.
Physiological experiments will be introduced to show the challenges in experiment design and analysis for such studies, and to illustrate our findings about the relationships between designer’s mental effort and mental stress, which are quantified by electroencephalography (EEG) and heart rate variability (HRV), respectively. Future trends in this research will also be discussed.
Applications of this scientific theory will be presented, covering education design, organization behavior, and role of perception in creative design.
In addition, this talk will introduce a set of criteria to evaluate the value and significance of a researcher’s work from the perspective of four stages of a scientific discipline and four kinds of scientists.
报告人简介：Dr. Yong Zeng is a Professor in the Concordia Institute for Information Systems Engineering at Concordia University. He is NSERC Co-Chair in Aerospace Design Engineering (July 2015-June 2020) and was the Canada Research Chair (Tier II) in design science (April 2004 - August 2014). He is an Editor-in-Chief of Journal of Integrated Design and Process Science (published by IOS) and an editorial board member of Computers in Industry (by Elsevier). His research aims to understand and improve creative design activities, which crosses design, computer science, mathematics, linguistics, and neurocognitive science. He has proposed the Environment-Based Design theory.Prior to joining in Concordia in August 2003, he was a research associate at National Research Council of Canada for about two years after he received his Ph.D. from Mechanical and Manufacturing Engineering at the University of Calgary in 2001. He obtained another PhD degree in Computational Mechanics from Dalian University of Technology in 1992, where he also received his Masters degree in 1989. Between his two PhD studies, he was a faculty member in the Department of Civil and Architectural Engineering at the Institute of Logistics Engineering, where he completed his B.Eng degree in Structural Engineering in 1986.
