An Aeronautical System Functional Logic Co-simulation Method Crossing Multi-architecture Levels in the MBSE Approach

Model-based system engineering (MBSE) uses the architecture model to drive system development and has been widely used in aeronautical and aerospace systems development. System functional logic co-simulation is essential to performing early-stage verification in architecture modeling. Still, there is no clear guidance how to perform the simulation in the system engineering life cycle. This paper proposes a system functional logic co-simulation method crossing muti-architecture levels, which gives a clear system functional co-simulation approach. The method includes three-level simulation processes and five simulation step. This modeling approach takes full advantage of the SoS architecture model and conforms to the V model. It builds a unified multi-architecture functional co-simulation way, guaranteeing the different architecture level model consistency and saving cost and time in the modeling practice.
