An optimization approach to the locomotive scheduling problem in Brazilian railways

Locomotives are among the most significant railway operations expenses and capital cost. In many Brazilian Railways, the locomotive assignment to trains are totally defined by the expertise of employees who works for those companies without any computational tools based on operational research concepts. This results in poor locomotive scheduling and the consequences are observed in the utilisation and productivity metrics. Research has been conducted to identify the related works developed in the locomotive scheduling and locomotive assignment context and the use of operational research techniques to develop an optimisation approach that guarantees the needs related to the real problem of Brazilian Railways. This paper presents the developments that have resulted in a mathematical model to solve the locomotive scheduling problem in Brazilian Railways. A case study is discussed, where the resulting model has been applied in the Vitoria-Minas Railroad (EFVM), owned by Companhia Vale do Rio Doce (CVRD) and is one of the most important and productive in Brazil. Finally, the results make possible to view the main differences between a real-life locomotive assignment and the locomotive scheduling based on the proposed optimisation approach.
