| 摘 要： | 本文分析了六种低成本冗余结构的可信性的定量属性，包括可靠度、MTTF、可用度、MTBF、可维度和MTTR。这些低成本冗余结构是；冷备用双模动态冗余结构、热备用双模动态冗余结构、双侯静态冗余结构、双模比较──单模切换结构、双摸负载分担──单模切换结构和N＋1冗余结构。根据每种结构所可能具有的维修特性，分别给出了相应可信性属性在不可维和可维情况下的计算表达式。

| Abstract: | In this paper, the important parts of quantitative attributes of dependability of six types of low-cost redundant structures are analyzed. The considered attributes are reliability,mean time to failure (MTTF), availabi1ity,mean time between failure (MTBF),maintainability and mean time to repair (MTTR ). The redundant structures are cold dual - module dynamic redundancy structure, hot dual- module dynamic redundancy structure, dual - module static redundancy structure, dual - module comparing redundancy-simplex switch structure, dual - module load sharing-simplex switch structure and N 1 redundancy structure. |
