Our work under RT-134 has resulted in an initial, functional concept for a SoS analytic workbench (SoS AWB) that uses a suite of computational tools to facilitate better informed decision-making for SoS architectural evolutions; the tools include: (SODA/SDDA) – System Operational Dependency Analysis/System Developmental Dependency Analysis, Multi-Stakeholder Dynamic Optimization (MUSTDO), System Importance Measures (SIMs), and Robust Portfolio Optimization (RPO).
The workbench provides a means of addressing SoS practitioners’ ‘archetypal questions’ in scenarios where size and/or interdependencies between systems are high. The workbench also enables analysis of capability and risk during the conduct of SoS evolution as patterned after the WAVE model. Our primary and common use case demonstration problem involves a Naval Warfare Scenario (NWS) that is based on the architecture of the Littoral Combat Ship (LCS). Each of the tools has used this common case study to illustrate the value in each tool performing various types of SoS level architectural analysis. While continuing basic research on each of the methods, our FY15 effort emphasized transitioning of the AWB for test in practical settings.
