| dc.description.abstract | This thesis presents a process and tool that generates representative preliminary ship models and arrangements for use in vulnerability analysis in the Concept and Requirements Exploration (CandRE) process used at Virginia Tech. CandRE uses a Multi-Objective Genetic Optimization (MOGO) to explore the design space for non-dominated ship design solutions based on design effectiveness, risk, and cost. Vulnerability is assessed as part of the CandRE using a Preliminary Arrangements and Vulnerability (PAandV) model. Representative ship arrangements for specified combinations of ship system options are created based on operability needs, ship mission needs, and improved vulnerability. These are then analyzed for vulnerability and are used to calculate a representative Overall Measure of Vulnerability (OMOV) which is used to calculate the Overall Measure of Effectiveness (OMOE) in the MOGO. | en |
| dc.description.abstractgeneral | This thesis presents a process and tool for ship vulnerability analysis in early stage ship design. Vulnerability is defined as the probability of ship kill after taking damage from a weapon. The vulnerability is assessed on representative ships that are generated based on the systems required for the ship missions. The analysis results are used in the design process to compare different ship designs based on their effectiveness, risk, and cost. This thesis creates the representative ship arrangements based on expert opinion, ship characteristics, and a location damage analysis. This process considers the vulnerability of a design in calculating the effectiveness of the design to incorporate vulnerability early in the design process. | en |
