An Aeronautical System Parameters Modeling Method Crossing Muti-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 parameters modeling is an essential part of performing early-stage verification in architecture modeling. Still, there is no clear guidance on performing the parameters modeling in the system engineering life cycle. This paper proposes a system parameters modeling method crossing muti-architecture levels, which gives a clear system parameters modeling approach. The method includes five-level parameters modeling processes, including mission-level parameters modeling, task-level parameters modeling, platform-level parameters modeling(equals SoS resource-level), subsystem-level parameters modeling, and equipment-level parameters modeling. This modeling approach takes full advantage of the SoS architecture model. It builds a unified SoS engineering and System engineering parameters modeling way, guaranteeing the different architecture level model consistency and saving cost and time in the modeling practice.
