在新一代的集成模块化航空电子系统中,机载软件采用开放的分布式架构,其中模块共享各种公共资源,并且彼此之间进行复杂的交互,从而导致模块故障易于传播,因此可靠性高。机载软件可能会减少。 机载软件的分析,测量和改进已成为需要解决的重要问题。 针对机载分布式软件的特点,提出了一种基于AADL的误差建模和可靠性分析方法。 利用AADL体系结构模型中的关键信息,可以生成AADL错误模型来描述机载分布式软件的故障行为。 在此步骤的基础上,使用灵敏度分析方法来分析系统可靠性。 因此,设计人员可以在开发的早期阶段找到影响系统可靠性的关键模块,从而在决策的基础上提高系统的可靠性。

21 7Plus TM is a methodology and a software tool that was developed by the Reliability Information Analysis Center (RIAC) to aid in the assessment of system reliability. It is the next generation of the PRISM ® software tool initially released by the Reliability Analysis Center (RAC) in 1 999 (which became RIAC in 2005) and contains twice the number of models as the original PRISM ® tool. 1 The original version of PRISM ® contained embedded models that are used to estimate the failure rate of various components when exposed to a specific set of stresses that are defined by the user. Since the time PRISM ® made its debut in the user community, the equations comprising the component reliability prediction models, which form the basis of PRISM ® , were not made available in printed form. As such, a user of the software tool could not see the exact equations that comprised the models. It is always advantageous for analysts to be able to review details of the models, so that the results can be better interpreted. This Handbook is published to make available the equations and model parameters that form the basis of the 21 7Plus TM methodology
