An Aeronautical System Context Analysis and Modeling Method Crossing Multi-architecture Levels in the MBSE Approach

Model based system engineering (MBSE), which uses the architecture model to drive system development, has been widely used in aeronautical and aerospace systems development. System context modeling is an essential part of architecture modeling, but there is no clear guidance on how to perform the system context modeling in the system engineering life cycle. This paper proposes a system context analysis and modeling method crossing multi-architecture levels, which gives a straightforward system context modeling approach. The method includes three-level analysis processes: platform-level context modeling, subsystem-level context modeling, and equipment-level context modeling. This modeling approach takes full advantage of the SoS architecture model. It builds a unified SoS engineering and System engineering structure modeling way which will guarantee the different architecture level model consistency and save cost and time in the modeling practice.
