- The research was the result of EPSRC grant EP/M007243/1. For the first time, an exact method (branch-and-price) is used for train unit scheduling with practical application (over 500 trains). An independent integer programming framework was developed allowing customised branch-and-bound strategies, as opposed to usual approaches where a commercial solver is used directly. Industrial partners such as First and ScotRail were involved in providing datasets and ensuring practical results. Cacchiani et al (https://doi.org/10.1287/trsc.2018.0858) build on the work in their railway rolling stock planning problem.
