Design Metrics for Electric Warship Design

Abstract -- As the Navy moves towards an all electric warship, the selection of the automation and control system architecture becomes an increasingly pressing issue. It is desired that the control system yields a ship which is highly robust with respect to battle damage in the form of cascading system failures. However, comparing the performance of different strategies has become a difficult issue. In this presentation, design metrics and an accompanying modeling strategy are proposed which should enable the control strategies to be systematically compared. These design metrics are based upon the concepts of operability and dependability, upon finding the worst case scenario over a range of events, and upon finding control parameters which yield the best worst case performance.
