NAFEMS Americas and Digital Engineering (DE) teamed up (once again) to present CAASE, the (now Virtual) Conference on Advancing Analysis & Simulation in Engineering, on June 16-18, 2020!

CAASE20 brought together the leading visionaries, developers, and practitioners of CAE-related technologies in an open forum, unlike any other, to share experiences, discuss relevant trends, discover common themes, and explore future issues, including:
-What is the future for engineering analysis and simulation?
-Where will it lead us in the next decade?
-How can designers and engineers realize its full potential?
What are the business, technological, and human enablers that will take past successful developments to new levels in the next ten years?

Resource Abstract

With Digital transformation at a rise leveraging models is used to scope out requirements focused on key gaps related to mission success. Model based capabilities are linked to the evaluation of key requirements through various reference missions in conjunction with adversary models, mission assurance models.



SAIC is at the forefront of applying Digital Engineering in helping to scope out requirements that help bridge gaps in analyzing the effect of design choices on mission success. We use end user reference missions, along with Model Based Engineering techniques, to help evaluate key requirements in terms of reference missions. We do the same evaluations with adversary and mission assurance models.



We need a user-friendly and easy-to-learn method so that engineers can use modeling software. The modeling software should permit traceability and interoperability between mission models, system-of-systems engineering models, and all the subsets of engineering models. We believe a tool used for mission engineering can achieve the required traceability and interoperability. The tool is the Advance Framework for Simulation, Integration, and Modeling (AFSIM).



Current engineering processes for AFSIM requires not only a deep knowledge of the system architecture, but also a technical know-how of the AFSIM syntax. As a result, a specific niche of skills is required for individuals to create models and scenarios for mission engineering using AFSIM. A steep there is a steep learning curve is an issue for new users. SAIC has develop a tool called Resilient Architecture Validation Environment (RAVE), to resolve this issue. At the mission engineering level, RAVE has the ability to create scenarios without being an expert in AFSIM syntax. We achieve the ease of use by using a single source AFSIM library built within an organization. RAVE allows for faster scenario development time and optimization, applying the ModelCenter software for evaluating mission success. Our methodology links requirements to mission success to identify key gaps.



Additionally, it provides an interaction with external scripts or programs, such as Python and java, to aid in calculating mission metrics and data visualization. At the engineering process level, RAVE can connect to ModelCenter® by Phoenix Integration and Cameo Systems Modeler™ by No Magic, Inc. This creates a feedback mechanism for design optimization connecting MBSE, MBE, and Mission Engineering.
