UNMANNED UNDERWATER VEHICLE MISSION SYSTEMS ENGINEERING PRODUCT REUSE RETURN ON INVESTMENT

Unmanned Underwater Vehicles (UUVs) accomplish a wide spectrum of missions ranging from generic to extremely specific. Although not all UUVs can accomplish all missions, there is significant replication of the requirements and the systems across the family of UUVs. The design process for UUVs balances operational requirements, design feasibility, expected performance, schedule, budget, and ultimate system and life-cycle costs. The U.S. Department of Defense does not have an established process for developing UUV Systems Engineering (SE) requirements. This results in duplicative development efforts adding unnecessary costs to UUV programs. This paper investigates the SE requirements and interfaces across various UUV mission spaces to establish complexity and reuse weights. A Constructive SE Cost Model (COSYSMO) is applied to determine the cost advantage to reuse SE requirements for UUV assets across different mission spaces to determine an overall SE effort. Requirements from the baseline mission are then compared with requirements from eight other missions, and the efforts compared to determine a return on investment (ROI) for using previous missions as a baseline. Utilizing the resulting UUV requirement cost versus ROI can serve as a starting point for future UUV program concept design.Civilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyApproved for public release.
