Draft Study Examines Use of Appointment System on Upper Mississippi River
The study presents and evaluates a discrete event-based simulation model for potential use in investigating the lower five 600-feet long lock chambers of the UMR-IW navigation system. The model is employed to identify the potential impacts of a specific traffic management policy, namely re-sequencing commercial tows in lock queues to replace the existing first come, first-served policy.
Tradable Permits for Inland Locks Studied
The objective of the study is to design a testable mechanism for the inland waterway system that would allow individuals to reduce their overall transportation cost, reduce uncertainty associated with potential delays and place a dollar value on the benefits of reducing the duration of, or even eliminating, critical delays. Specifically, the researchers explore the use of a system of tradable priority permits issued to existing river barge operators in proportion to existing and historical operations on the river.
Project Report Presented on Longer-Term Forecasting of Commodity Flows on Mississippi
The report reviewed the researchers overall approach and presented current results. Outstanding issues related to the deterministic model and risk questions were reviewed. The goal of the project is to collect and analyze important data impacting world trade in grain and oilseeds; develop an analytical model to analyze world grain and oilseeds trade; and conduct a risk analysis.
NETS Team Members Visit St. Lawrence Seaway
The participants received a general overview of the system; background on performance measures and service level objectives; information on the Seaway’s implementation of an automatic identification system; and details on the Seaway’s use of a Traffic Management System to manage transits.

HarborSym to Be Featured in Training Course
There will be two 1 ½ day training sessions held between 29-31 August in Mobile, Alabama. The courses will provide in-depth exposure to the models’ capability through lecture and hands-on activities. Both sessions are available to Corps employees and are being offered without tuition fees.
For information on HarborSym, please contact Shana Heisey at IWR . To express interest in attending the training, please contact Ken Claseman at the Center of Expertise.
