Pai Zheng is currently an Assistant Professor and Wong Tit Shing Endowed Young Scholar in Smart Robotics in the Department of Industrial and Systems Engineering at The Hong Kong Polytechnic University. His research interests include smart product-service systems, human–robot collaboration, and industrial AI. Dr. Zheng is a senior member of IEEE and CMES, a member of ASME and HKIE, and a research affiliate of CIRP. He serves as the Associate Editor of the Journal of Intelligent Manufacturing and the Journal of Cleaner Production, and is an editorial board member of the Journal of Manufacturing Systems and Advanced Engineering Informatics. Chun-Hsien Chen is a Full Professor at the School of Mechanical and Aerospace Engineering of Nanyang Technological University, Singapore, where he is also Director of the Design Stream and Professor-in-Charge of the Design & Human Factors Laboratory. He has several years of product design and development experience in industry. His teaching and research interests are in collaborative/human-centric, consumer-oriented product design and development, knowledge engineering, design sciences, engineering informatics, and artificial intelligence in product/engineering design. He has more than 280 publications in these areas. Ms. Wang Zuoxu, is currently a Researcher with the Delta-NTU Corporate Laboratory for Cyber-Physical Systems, in the School of Electrical and Electronic Engineering, at Nanyang Technological University (NTU), Singapore. She has submitted her Ph.D. thesis in the School of Mechanical and Aerospace Engineering, at NTU, in 2020 and received the B.Eng. degree from the School of Mechanical Engineering, Tianjin University, China, in 2016. Her research interests mainly lie in smart product-service systems, and engineering design informatics.
