| 摘 要： | 为了克服传统可靠性测试方法在验证高可靠性指标时测试持续期太长的困难，针对实时多任务软件的特点，提供了一种融基于体系结构的系统可靠性建模、最大熵原理、贝叶斯统计推断为一体的多级高可靠性测评方法。数值仿真表明，该方法在不降低验证测试置信水平的基础上，能有效缩短验证测试持续期。

| Abstract: | In order to solve the problem that the classical reliability testing method，which treats the testing target software as a monolithic block，can’t satisfy the requirements of high reliability testing due to the long testing duration，a hierarchical reliability testing approach was provided in this paper based on the characteristics of real-time multitasking software.The method unified architecture-based system reliability modeling，maximum entropy principle and Bayesian inference.Numeral simulation shows that it is effective to reduce the testing duration without abating the confidence level for the testing results. |
