Learning to Route Electric Trucks Under Operational Uncertainty
Stavros Orfanoudakis, Ziyan Li, Ruixiao Yang +4
Electric truck operations require routing decisions that remain feasible under limited battery range, long charging times, travel and energy consumption, and competition for shared…
Heuristic Search as Language-Guided Program Optimization
Mingxin Yu, Ruixiao Yang, Chuchu Fan
Large Language Models (LLMs) have advanced Automated Heuristic Design (AHD) in combinatorial optimization (CO) in the past few years. However, existing discovery pipelines often re…
Joint Scheduling of DER under Demand Charges: Structure and Approximation
Ruixiao Yang, Gulai Shen, Ahmed S. Alahmed +1
We study the joint scheduling of behind-the-meter distributed energy resources (DERs), including flexible loads, renewable generation, and battery energy storage systems, under net…
Co-Optimizing Distributed Energy Resources under Demand Charges and Bi-Directional Power Flow
Ruixiao Yang, Gulai Shen, Ahmed S. Alahmed +1
We address the co-optimization of behind-the-meter (BTM) distributed energy resources (DER), including flexible demands, renewable distributed generation (DG), and battery energy s…
