中文摘要： 分布式综合化航空电子系统（DIMA）可看作是具有综合模块化结构，并采用交换互连的子功能区域在机载环境中的分布式集成，更加强调任务关键和安全关键等关键属性在子功能区域集成过程中的一致性性能，并集中体现于系统完整性。本项目针对综合核心处理和综合航电网络完整性不能对接而导致的一致性保障能力中断问题，通过将具有关键属性保障机制的分区管理技术在综合航电网络上进行延伸，创建具有故障封闭一致性的航电分区综合自组织模型，并利用分区边界形成的功能需求和性能保障能力的自封闭性，建立综合核心处理和综合航电网络完整性对接方案；基于此，发展分区综合模型下分布式综合化航电系统时间完整性和集成完整性理论，提出任务剖面下基于分区边界的时间完整性匹配调度策略和分区边界约束下的确定性轨迹分析方法，提出基于分区边界的集成完整性演进模式和分区集成准入控制方法。通过本项目研究，为我国大中型飞机下一代综合化航电系统设计奠定理论基础。

英文摘要： Distributed Integrated Modular Avionics system （DIMA）can be seen as a distributed integration of sub-function areas with integrated modular structure and switched connection on airborne environment. During the process of integration, it pay more attention to the consistency performance of mission-critical and safety-critical guarantee capability, which is mainly concentred in system integrity. To solve the problem of consistency guarantee ability interrupt caused by the integrity mis-docking between integrated core processor and integrated avionic network, this research mainly focuses on the modeling of avionics partition integrating self-organized model with fault containment by introducing partition management technology with critical attribute guarantee mechanism into integrated avionic network. Then the integrity docking scheme between integrated core processor and integrated avionic network will be established by using partition boundary self-containment ability for function demand and performance guarantee. Based on the partition integrating model, the theory of time integrity and integrating integrity will be developed, including the matching scheduling strategy of time integrity based on partition boundry under mission profile, the trajectory approach evaluation method under partition boundry restrictio
