Abstract

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.
