Evolution of Operability-Based Performance Metrics for Assessment of Mission Performance

Nowadays, electric warships are involved in complex missions involving multiple simultaneous operations. In order to ensure mission success, future ships must be designed in a way that optimizes their performance in presence of complex mission loads. The metric operability has played a major role in assessing mission performance. This paper discusses the evolution of this metric from fixed load-based early-stage shipboard electrical system design to the current approaches of using dynamic mission profiles. Results for a notional two-function problem involving multiple missions are shown to demonstrate the current state of operability-based approaches for the evaluation of power system performance.
