基于Arcadia方法的民机信息系统架构设计

Design of Civil Aircraft Information System Architecture Based on Arcadia

传统的基于文档的系统工程是目前民机研制的主要研制方法,存在需求获取不清晰、不同层级的需求与设计不一致、难以追溯以及设计方案更改难度大等问题。结合Arcadia方法和Capella建模工具,提出基于Arcadia的民机机载系统基于模型的系统工程研究方法。通过集成运行、系统、逻辑和物理的视景,构建了特定场景下的机载系统模型。研究表明,基于Arcadia的民机机载系统能够有效避免传统的基于文档式需求的风险和问题,保证了系统架构与需求分析的紧密融合。

Traditional document-based system engineering is currently the main development method for civil aircraft development.There are some problems that are unclear requirements acquisition,different levels of requirements and design inconsistencies,hardly trace the requirements and the design scheme is difficult to change.This paper,combined with Arcadia and Capella modeling tool,proposes a model-based system engineering research method for civil aircraft airborne systems based on Arcadia.By integrating the operational,system,logical,and physical visions,an airborne system model under a specific scenario is constructed.Research shows that the civil aircraft airborne system based on Arcadia can effectively avoid the risks and problems of traditional document-based requirements,which ensures the close integration of system architecture and requirements analysis.
