中文摘要： 综合模块化航空电子系统的资源共享和功能组件综合为动态重构提供了可能，传统的以安全参数分配和验证为核心的“V”型安全性评估方法已无法应对动态重构带来的系统构型高度灵活和动态重构空间爆炸等问题，已成为制约大型客机航电发展的技术难题。本研究首先通过研究动态重构IMA系统的体系结构，分析动态重构特性引入的柔性安全性需求；采用形式化语言构建系统安全模型，以模型扩展方式实现多重配置方案间的安全参数融合，解决多重配置间资源重叠带来的系统安全性等级模糊的问题；最后综合实际航电系统约束，完成动态重构IMA系统构安全性评估。本项目的研究成果可以为我国适航当局应对新兴航电技术提供技术支持，同时给我国航电系统研制、集成单位提供系统安全性设计和评估理论指导。

英文摘要： The dynamically reconfigurable feature has been integrated to the next-generation integrated modular avionics. The traditional V-shaped safety assessment method, which based on the safety parameter assignment and validation, has been unable to cope with the highly flexibility and the configuration state space explosion brought by the dynamically reconfigurable feature. This issue has attracted the concerns from the national aviation research organization, airworthiness authorities, while has not yet been practical solved. In this study, firstly the the architecture of IMA system is analyzed and the flexible safety requirements of the dynamic reconfiguration are proposed. Secondly, the safety model of the IMA is constructed using the formal language and extended to achieve safety integration among multiple configurations, the ambiguous issues of the safety level of the IMA system with multiple reconfigurations which have overlapped resources is solved. Finally, the safety assessment framework of the dynamically reconfigurable IMA is established with the consideration of the actual restrict. This study can provide technical support for airworthiness authorities to deal with the emerging avionics technology which will improve the capacity of the authorities of the airworthiness review. Meanwhile, it can provide safety assessment guideline for avionics system development, system integration unit.
