In this talk, we investigate Evolutionary Multiobjective Optimization (EMO) and related applications, including smart grid system designs, multiobjective control, robot navigation, antenna design, and radar waveform designs. Terminologies such as Multiobjective Optimization Problem (MOP), Pareto dominance, Pareto optimal set, and Pareto front are introduced. Algorithms termed Multi-Objective Evolutionary Algorithms (MOEAs) are discussed. By solving MOPs using MOEAs, a set of Pareto optimal solutions is obtained. To render multiobjective optimization relevant to practical applications, a final solution must be selected from the Pareto optimal set. This leads to Multi-Criteria Decision Making (MCDM). A minimum Manhattan distance approach to MCDM is discussed, as well as existing methods from the fields of operations research and evolutionary computation. We conclude this talk by presenting some informative illustrations regarding Pareto fronts and mentioning a few possible research directions for EMO.


Wei-Yu Chiu received his B.S. degree in electrical engineering and the Ph.D. degree in communications engineering from National Tsing Hua University (NTHU), Hsinchu, Taiwan in 2006 and 2010, respectively. From 2011 to 2012, he was a Postdoctoral Research Fellow with the Department of Electrical Engineering, Princeton University, Princeton, NJ, USA. He was a Visiting Scholar at Oklahoma State University in 2015. From 2013 to 2017, he was an Assistant Professor of Electrical Engineering with Yuan Ze University (YZU), Taiwan. He is currently an Assistant Professor of Electrical Engineering with NTHU, Taiwan. His research interests include multiobjective optimization, smart grid, and computational intelligence. Dr. Chiu received the Young Scholar Research Award bestowed by YZU in 2014, the Exploration Research Award bestowed by Pan Wen Yuan Foundation in 2015, the Outstanding Young Automatic Control Engineering Award bestowed by Chinese Automatic Control Society in 2016, and the Outstanding Young Scholar Academic Award bestowed by Taiwan Association of Systems Science and Engineering in 2017. Since 2015, he has been serving as an Organizer/Chair of the International Workshop on Integrating Communications, Control, and Computing Technologies for Smart Grid (ICT4SG). He is the Lead Guest Editor of a few feature topics in IEEE Communications Magazine.
