Rail is frequently used for moving coal between mines and ports, and interactions between train and crewing requirements can create highly complex problems.
Recently Matt Herbert, an optimisation consultant at Biarri Commercial Mathematics was invited to present an approach to Coal Train Crew Scheduling at the Queensland University of Technology, hosted by ASOR.
Matt provided insights into the problems many mining and rail companies face when scheduling their crews. His formulation considered many aspects of the real world problem, including restricting the number of crew changes on each service, and variable start times for crews.
This approach is able to produce weekly crew assignments with high utilisation in run times of around an hour, down from existing manual methods requiring a day or more.
