RASIG Roundtable "Rapid Simulation Modeling of Rail Operations."Sunday, Nov. 7, 1-5 PM, Marriott Hotel, Room 412
Coordinator, Erick Wikum, Schneider National, 920-592-2159.
Erick Wikum made introductory remarks. Alan Brown of Norfolk Southern related experiences in using simulation to impact decisions that required rapid response, Simulation on a Shoestring. Dr. John Carson of AutoSimulations Inc. suggested ways that software might aid in such exercises in Tools for Rapid Simulation Modeling for the Paper Switching Application.

Dutch Treat DinnerSunday Evening
RASIG members and others who are interested gathered at the Plough and Stars for dinner.
This session will focus on presenting the issues and factors that are critical in freight transportation logistics. Methodologies used in addressing these logistics issues/factors by shipper and transportation service providers (primarily focusing on motor carrier and railroad) will be discussed.
We propose an optimization model designed to increase operational efficiency of intermodal trains. We explain how this model can be used in various planning settings, how it can be tailored, and how it can be extended to aid in decision making above and beyond intermodal train scheduling and container routing.
We have created a locomotive fleet planning system based on NS Locomotive Routing Model developed at Princeton University CASTLE research lab. The routing model has been calibrated for NS operations based on historical data. LPS can be used to identify the tradeoffs between fleet size and locomotive utilization and train delay. We present an overview of the software and a summary of fleet sizing experiment results.
In this talk, we present a strategic fleet planning system that was
developed for a study at VIA Rail Canada. Given a target weekly train schedule
with passenger demand, the system determines unit cycles such that demand
is satisfied, inspection requirements are met, and total (fixed and variable)
costs are minimized, while allowing some flexibility on train departure
times. The system also includes a tool to evaluate passenger demand for
a given train schedule.
