Abstract: To calculate the availability of integrated avionics based on double-star network, this paper computes the network availability algorithmically, derives analytical expressions and simulates the formula with Matlab for several different redundancy schemes in same double-star network topologies. The design guideline of integrated avionics redundency schemes is proposed according to the results of simulation.

Key words: double-star topology, availability, redundancy

摘要： 针对基于双星型网络的航空综合化设备可靠性计算问题，提出该网络拓扑可靠性的理论计算方法，对比分析了不同配置方法下双星型网络拓扑可靠性，推导出不同网络拓扑配置可靠性的计算公式，并用Matlab进行仿真，根据仿真结果给出基于双星型网络拓扑综合化设备资源冗余方案的设计指南。
