Introduction
What Does The Modeler Have To do?
• P & G Compliant
• Use Engineering Input
• Provide Environmental Inputs
• Determine Key Drivers

Link To Structural Reliability
• Engineering Reliability Analysis– Detailed structural condition
studies– Develop hazard functions &
Probabilities of Unsatisfactory Performance (PUPs) for major lock components
– Identify consequences of unsatisfactory performance (Repair costs & Closures)
• Economic Reliability Analysis– Simulate 50 year project-life– Evaluated alternatives

Are environmental values woven into the formulation and evaluation process to insure that we are practicing adaptive management?
• EOP - Environmental concerns are part and parcel of all USACE missions, decision-making, programs and projects
• Economic Outputs linked to NAVPAT
Integration of Environment

What We Model
Waterway Cost Changes That Arise From Changes:– Traffic Levels and Flow Patterns– Vessel Fleet– Lock Operation (Lockage Polices and Helper Boats,
for Example)– Structural Reliability of Lock Facilities– Taxes and Fees

What We’d Like to Model
• Benefits From Waterway System Improvements
• In So Doing, We Want the Model to be:– Realistic– Consistent With Theory– Consistent With State of Practitioners’ Art
• NAS Had Some Specific Comments
