Abstract
The Naval Ship Design Concept and Requirements Exploration (C&RE) process used at Virginia Tech is based on a Multi-Objective Optimization approach that explores the design space to identify a Non-Dominated set of ship design solutions ranked by cost, risk, and effectiveness. The current method of calculating an Overall Measure of Effectiveness (OMOE) used in this approach is based on expert opinion and pairwise comparison. Despite the good results obtained using expert opinion, more direct physics-based Operational Effectiveness Models (OEMs) starting with a detailed Design Reference Mission (DRM) including mission Operational Situations (OpSits), conditions, and measures may provide greater confidence in the validity of the results and a perception that results are more unbiased and rational. This paper describes a method for building a Design Reference Mission (DRM) composed of multiple Operational Situations (OpSits) required by the ship’s mission. The DRM is defined using a Model Based Systems Engineering (MBSE) approach and a Total-Ship System Architecture to define and understand the relationships between various aspects of the ship design and their relationship to operational effectiveness. The system architecture is based on the DoD Architecture Framework (DoDAF 2.0). It includes the DRM and enables the development of Operational Effectiveness Models (OEMs) as an alternative to an expert opinion-based OMOE. A notional US Coast Guard (USCG) Offshore Patrol Vessel (OPV) is used as an example in this paper. The ship design architecture and Design Reference Mission are based on the OPV mission requirement specified in a notional Initial Capabilities Document (ICD). 1.
