Artyom Nahapetyan, Ravindra K. Ahuja, F. Zeynep Sargut, Andy John, and Kamalesh Somani. 17. A Simulation/Optimization Framework for Locomotive Planning. In 7th Workshop on Algorithmic Approaches for Transportation Modeling, Optimization, and Systems (ATMOS'07). Open Access Series in Informatics (OASIcs), Volume 7, pp. 259-276, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2007)


In this paper, we give an overview of the Locomotive Simulater/Optimizer (LSO) decision support system developed by us for railroads. This software is designed to imitate locomotive movement across a rail network, and it simulates all four major components of the system; trains, locomotives, terminals, and shops in an integrated framework. It includes about 20 charts that allow evaluating system performance using standard measures. LSO can be used by locomotive management to per- form "what-if" analysis and evaluate system performance for different input data; it provides a safe environment for experimentation. We have tested the software on real data and output showed that the software closely imitates day-to-day operations. We have also performed differ- ent scenario analysis, and reports illustrate that the software correctly reflects input data changes.
