Abstract

As simulation engineers and subject matter experts, we often focus on solving complex technical challenges within a specific technical or physical domain leveraging a specific simulation approach. However, to maximize the impact and integration of our work, it's essential to understand Systems Engineering (SE) and Model-Based Systems Engineering (MBSE) practices that become increasingly important in 21st century engineering projects. The INCOSE vision 2035 provides a picture of how 21. century engineering will look like in a few years from now Way more model-based and less document based, way more tightly integrated across domains, especially with respect to Simulation. this requires the still often disconnected communities to come together more closely, which is the ambition and charter for the for the INCOSE NAFEMS Systems Modeling & Simulation Working Group for the case of MBSE and system simulation. This talk aims to remove the gap between Simulation Engineers and practitioners and the realm of SE/MBSE by offering insights into how SE/MBSE ideas and practices can enhance collaboration between engineers and improve (simulation) project outcomes. Attendees will learn how adopting SE and MBSE concepts and approaches can help to manage complexity, ensure traceability, and integrate their simulation models more effectively within larger system architectures and system models. By understanding core SE and MBSE principles, workflows, and tools, simulation engineers can improve communication with cross-functional teams, contribute to system-level requirements and technical concepts, and elevate the impact and value of their work in modern engineering projects. Specifically, we will cover and provide insights on Systems engineering and Model-Based Systems Engineering (MBSE), key SysMLv2 concepts relevant for simulation engineers such as Analysis, VerificationAnalysis, and TradeStudy, integration of simulation within SE and MBSE Frameworks, skills required for simulation engineers working with SE/MBSE personnel, and provide an outlook on future trends and the evolving role of simulation engineers in the context of SE & MBSE.
