On the morning of July 8, 2024, at the invitation of the School of Management, Assistant Professor Tang Qinshen from the Nanyang Business School at Nanyang Technological University, Singapore, gave an academic lecture titled "Vehicle Repositioning under Uncertainty" in the School of Management's Room 118. This lecture was the 17th session of the 2024 Overseas Expert Lecture Series at the School of Management. The lecture was chaired by Professor Fu Chenyi from the School of Management, with the participation of faculty and graduate students from the school.

At the beginning of the meeting, Fu Chenyi provided a brief introduction to Tang Qinshen's personal background and academic achievements, and the attendees warmly welcomed Professor Tang Qinshen's visit. During the lecture, Tang Qinshen discussed the vehicle repositioning problem in shared vehicle systems under uncertain conditions such as demand, destination, and travel time. He constructed a dynamic robust optimization model for shared vehicles using the entropy risk measurement method and reformulated it as a general mixed-integer convex/linear optimization model. The research results indicated that the proposed entropy robust optimization model outperforms the benchmark model in terms of average service level and average repositioning cost.

During the report, Tang Qinshen also answered some questions from the attending faculty and students. After the lecture, the attendees had an in-depth exchange with Tang Qinshen, and the atmosphere was lively. This lecture provided new insights into the combination of vehicle scheduling and optimization models, which will be greatly inspiring for everyone's future research.
