摘　　要：针对负载分担可修的并联系统模型,考虑了控制器可修,修理工多人的情形,并且在将控制器作为关键部件优先维修的规则下,对模型进行了可靠性分析.最后用一个实例,求得一些常见的系统可靠性指标,并结合部件的失效率和修复率进行了深入讨论,在系统不可修时求得其可靠度和平均寿命.For the repairable parallel system with load-sharing, the controller can be repaired, the number of repairmen is larger than one, the key component to be repaired in priority are considered in this paper, we have analyzed the model reliability. Some common reliability index are calculated in a practical example in the end, when the system cannot be repaired, the intense discussion combined with the component failure rate and repair rate are given, the RELIABILITY and MTTF are derived.
