Y. Cheng

Assistant Professor


3917 2594


HW 8-11


Dr. Yao Cheng is an Assistant Professor with the Department of Industrial and Manufacturing Systems Engineering, The University of Hong Kong. Dr. Cheng received her PhD degree in Industrial Engineering from Rutgers, the State University of New Jersey. Dr. Cheng’s research mainly lies in reliability and resilience modeling and optimization of both generic systems such as complex networked SoS and application-oriented products such as charging piles and solar panel modules. Her research draws tools from deterministic models (e.g., operations research), stochastic models (e.g., probability and statistics, stochastic process) and data science. Her research has been published in and promoted by leading journals in the reliability and IE field such as IISE Transaction, Reliability Engineering and System Safety, IEEE Transactions on Industrial Informatics, IEEE Transactions on Reliability, International Journal of Production Research. Her research also has been funded by Research Grant Council, University Research Council and Industry.
