摘要
本文从一种分布式系统可靠性指标验证面临的问题出发,结合可靠性论证的覆盖性原则,通过分析该分布式系统的特点,提出用最小功能单元MTBF和典型通道MTBCF作为分布式系统可靠性指标。然后,从可靠性验证的覆盖性原则出发,结合最新装备试验鉴定模式和通用质量特性论证要求,给出了分布式系统的可靠性验证方法。最后,结合案例说明了该方法的工程应用。
In this paper, starting from the problems faced by the reliability verification of a distributed system, combined with the coverage principle of reliability demonstration, and by analyzing the characteristics of the distributed system, the MTBF of minimum function unit and the MTBF of typical channel are proposed as the reliability indexes of the distributed system. Then, based on the coverage principle of reliability verification, combined with the latest qualification mode of equipment test and general quality characteristic demonstration requirements, the reliability verification method of distributed system is given. Finally, the engineering application of this method is illustrated by a case study.
