基 于 多 视 角 的 民 机 正 向 设 计 建 模 方 法

To address the problems of increasing complexity in coupling of modeling objects，insufficient modeling theory support，and lack of model description of stakeholder requirements in the system-of-systems oriented design of civil aircraft systems，we propose a multi-perspective-based modeling approach for civil aircraft forward design. First，the top-down mapping and correlation of civil aircraft forward design are clarified by analyzing the civil aircraft forward design process and Model-Based Systems Engineering（MBSE）methodology. Then，we introduce multiple perspectives to decouple and describe the civil aircraft design process，analyze the modeling elements and their logical relationships from each perspective，combine the design domain knowledge flow with the modeling process from each perspective，and describe abstractly the civil aircraft design model from multiple perspectives through the modeling language SysML. Finally，a modeling example of the cabin pressure control system is utilized to verify the effectiveness of this method for the design of civil aircraft systems.
