ABSTRACT：

In this talk, we study a continuous-time service network design problem, which holds great practical value but poses a significant challenge. To overcome the challenge, we propose an enhanced dynamic discretization discovery approach for the problem with deterministic travel times, and a novel robust optimization approach for the problem with uncertain travel times. The effectiveness of our models and methods is demonstrated through extensive computational experiments.
