STOTTLER HENKE ASSOCIATES, INC — Department of Defense SBIR Phase I: N142-083

Description

Development of complex systems requires attention to Human Systems Integration (HSI)the earlier the better. Systems engineering (SE) aims to balance discipline-specific concerns along with overall project cost, schedule, performance, and risk. The Framework for Assessing Cost and Technology (FACT) project uses SysML modeling and coupled simulation technology to dramatically improve concurrent SE early in concept development. However, FACT does not yet include modules supporting modeling and simulationand hence requirement-relevant preliminary assessmentsfor HSI disciplines. Stottler Henke proposes to develop tools that integrate with FACT under the rubric Concurrent HSI Analysis for Systems Engineering (CHASE). CHASE will leverage profile-extensible SysML modeling and existing HSI-relevant simulation approaches and tools. It will provide several distinctive capabilities: (1) standardized HSI model and metadata vocabularies; (2) reusable HSI-relevant model libraries; (3) heuristic modeling and analysis guidance; (4) automated simulation configuration; and (5) easier surrogate model generation. During Phase I, we will develop use cases and requirements, characterize key technologies for modeling and simulation, develop a core design, build a limited proof-of-concept prototype to demonstrate feasibility, and develop a plan for Phase II.
