Doctoral students presents work at transportation conferences

Posted: May 13, 2011

Eunsu Lee, doctoral candidate in transportation and logistics, has been invited to present at the Geospatial Information Systems for Transportation Symposium. Lee will present research from studying flooding in the Red River Valley, "Visualization for Transportation Network in Flood Region."

The study uses remote sensing datasets to create a three-dimensional (3D) transportation network for geographic information system application. The research includes bridges over the Red River and Interstate Highways 29 and 94 in the 3D model and estimates flooding over roadways. This visualization aids the public's understanding of flooding and transportation flow during a flood.

At the symposium, Lee also will attend workshops and presentations that will contribute to further research. The conference is sponsored by the American Association of State Highway and Transportation Officials, bringing together transportation students, government personnel and private industry leaders. The theme of the conference is "The Keystone of Transportation Information."

Lee also presented "Simulation of Base Stock Inventory Integrated with Transportation Strategy to Optimize Performance" at a recent conference of simulation scholars. The paper was co-written with Farahmand Kambiz.

The Winter Simulation Conference is the premier international forum for presenting advances in the field of system simulation. Lee was asked to present during the doctoral colloquium session focused on logistics, transportation and health. His submission was a finalist for the Best Student Paper Award.

In his study, Lee applied discrete-event simulation to three-layered manufacturing and distribution systems for simulating centralized and decentralized systems. He learned the balance between customer orders and logistics considering lot-sizes, such as pallets and truck configurations, was critical for inventory and transportation costs.
