Bo Zeng,  Sichuan Province, China, is a Doctor of Engineering and Professor. He is also a Postdoctoral Fellow of Management, and Doctoral Supervisor. He has been selected as Distinguished Professor in Chongqing Bayu Scholar Scheme  (2017) and Chief Distinguished Professor of Chongqing Technology and Business University (2022). Besides, he has been in the list of top 2% scientists in the world twice (2020, 2022). He is mainly engaged in the research of grey prediction theory and methods and their applications, and specializes in real-time imitation and dynamic simulation of the operation law and development trend of uncertain complex systems through computer software.Zhuanzhuan Shi, Shanxi Province, China, is a Ph.D. in Education and Associate Professor. She has published a dozen of articles and three monographs in the recent years and has hosted or participated in ten municipality-level projects. Grey theory and its application has become one of her research foci during her doctoral study.
