About Me
Hello! I'm a Master's student in Management Science & Engineering at Beijing Foreign Studies University (opens new window) where I am fortunate to be advised by Prof. Xi Chen. My research interests include topics in large-scale sequential decision-making and statistically efficient optimization under uncertainty. Specifically, I am interested in:
Methodologies:
- Approximate Dynamic Programming / Reinforcement Learning
- (Distributionally) Robust Optimization
Applications:
- Transportation and Logistics
- Renewable Energy

Near-Optimal Cost Function Approximation for Technician Routing and Scheduling
Working
Brief Intro: Basically, Cost Function Approximation (CFA) can be written as: , where and refer to decision and exogenous random vector in stage , is cost function and is any parametric function with parameter .
In CFA, how to design a “good” function and choose a “good” parameter is a fundamental problem, yet previous works usually propose specific formulations for specific problems and, to the best of my knowledge, there does not exist a general framework about how to design a “good” CFA.
In this paper, we aim to develop near-optimal formulation of CFA utilizing state abstraction and the relationship between regularization and robust optimization.Technician routing and scheduling with employees’ learning through implicit cross-training strategy
