Appropriate Simulation Model Identification during Model-Based Systems Engineering

Abstract

Model-Based Systems Engineering (MBSE) hinges on the use of models during development. Models enable several capabilities during development through concrete formalization of knowledge and data, while at the same time offering communication and reasoning support from application of abstraction. A primary capability enabled by models is simulation, and as a result simulation is promoted by many MBSE methodologies to support iterative decision-making during design. Nonetheless, simulation is a very complex capability, that requires significant investment in tooling and training. Likewise, enabling credible and valid simulation is a significant challenge in terms of progressive application during decision-making in development. In this article, we leverage the notion of appropriateness in the system modelling community and transfer these principles towards simulation as a tool in MBSE. By leveraging our experiences and previous work in the topics, we offer a pragmatic list of questions for practitioners to apply and guide them in the construction and application of simulation technologies in MBSE.
