Summary This research continues the DoD Systems Engineering Research Center (SERC) System Qualities Ontology, Tradespace and Affordability (SQOTA) Project, now Research Topic 209 (RT-209). This Phase 7 research includes collaboration with AFIT for system architecture modeling and cost estimation of Intelligence, Surveillance and Reconnaissance (ISR) mission variations involving heterogeneous teams of autonomous and cooperative Unmanned Aerial Systems (UAS) agents. NPS will provide cost modeling expertise, modeling tools, and analysis support. A focus will be on translations between models/tools in Model Based Systems Engineering (MBSE), specifically mapping architectural elements into cost model inputs to support automated costing.
Phase 7 research will address adding size complexity and hardware-oriented factors in the ISR architecture models for automated costing. This will account for hardware sizing and other cost attributes, and the ISR satellite architecture cost comparisons will be re-evaluated. We will devise methods with AFIT for capturing the additional information in MBSE models.
NPS will also continue extending its affordability research by supporting the development of Constructive Systems Engineering Cost Model (COSYSMO) version 3.0, continuing to calibrate domain-specific cost models with USC and NCCA, and to pursue COCOMO II extensions to estimate cost impacts of additional levels of security and improved maintainability. Allied NPS student research is developing a software maintenance model for a training simulator by analyzing Air Force empirical maintenance data.
