Major freight railroad operators in the United States own and maintain tens of thousands of miles of track and use thousands of locomotives to ship millions of tons of cargo each year. Planning and executing these operations requires solving problems with an enormous number of possible solutions on a daily basis. For many such problems, conceptualizing an appropriate mathematical model of the problem can be challenging. This talk will discuss logistics problems that arise in railyards, which essentially serve as sorting facilities for incoming and departing trains. We focus on problems associated with disassembling arriving trains, assembling departing trains, and the railcar movements required to efficiently accomplish these tasks. In particular, we present models and solution approaches for repositioning subsets of railcars in order to minimize the total required travel distance or maximize the number of railcars that depart on-time.
