Abstract:
The U.S. Navy designs and operates the most technologically advanced ships in the world. These ships incorporate the latest in weapons technology, phased array antennas, composite structures, signature reduction, survivability, modularity, power systems, computing systems, and automation. The modem day warship is an exceptionally complex system and the design process is long and intricate, spanning several years from feasibility studies to detailed design. The plethora of new technologies being introduced in any single ship design increases the complexity of the ship design process making it ever more challenging to meet the needs of the stakeholder in terms of capability, cost, and risk. Systems architecture provides a way to understand, design, and manage this complexity by representing the system as an abstraction of elements and the relationships between those elements. Model-Based Systems Engineering (MBSE) has been a recent initiative in the systems engineering community to enhance the systems engineering process by streamlining requirements traceability and improving communication amongst the various stakeholders. MBSE methods have been used in industry to develop systems architecture in a robust and comprehensive manner. In the ship design process, there is a significant need to ensure that the architecture is not only well-defined, but also addresses the needs of the stakeholders. This thesis explores the use of MBSE to develop systems architecture with application to Navy ship design and acquisition.
