  1. Asset Management Improved Reliability Models for USACE Navigation Structures PI: Yazmin Seda-Sanabria (GSL) Problem:Need for improved reliability models to predict actual field performance of Corps navigation infrastructure and assist in future investment planning of critical maintenance. • Currently used mechanical and electrical equipment models are based on annual failure rates, not specific to navigation structures. • Geotechnical models currently used yield inconsistent results on expected operational performance.

  2. Improved Reliability Models for USACE Navigation Structures Products: • Time-dependent (capacity vs. demand) reliability models for electrical and mechanical operating components. • Base geotechnical time-dependent reliability models. Benefits: • Significant cost savings on critical maintenance (including major rehabilitation) of Corps navigation infrastructure. • Improved engineering tools that can be integrated into economic models to make risk-based sound investment decisions.
