Recovery Algorithms for Ship Survivability

Phase I work performed by Electrical Distribution Design, Inc (EDD) evaluated use of a Linear Graph Iterator based approach for reconfiguration and recovery modeling and analysis of shipboard systems. This approach was originally developed by Virginia Tech and EDD for the Power Utility Industry. Several simplified ship system arrangements for electrical distribution, firemain and chill water were modeled and analyzed. Included in the models were multiple reconfiguration paths, prioritized loads, and relatively short loops and low cable impedances. In addition to demonstration modeling, EDD completed a significant amount of recovery analysis problem definition and integrated systems analysis software architecture definition work. Results demonstrated that: (1) EDD's Linear Graph Iterator model based approach is well suited for structuring shipboard system recovery analysis for both design and control; and (2) Significant synergy potential exists for using a Linear Graph Iterator based approach to structure concurrent Utility, Navy and Homeland Security critical infrastructure system reconfiguration and recovery design and control research.
