摘要: 由于根据人为经验给出k/n表决系统中k的设置具有随意性,根据系统单元承受的作用概率分布,利用应力-强度干涉理论,给出了单个单元的失效概率,由单元工作时的可靠与失效状态的转移情况,利用概率微分方程,建立了可修复k/n表决系统的动态可靠性预测模型,并给出了该模型的解。对可修复k/n表决系统中最少工作单元数目k的设置给出了理论依据。通过对算例的分析,表明了所建模型的准确性与可行性。

Abstract: For the k of k/n system is given according to the one's experience in the current, the probability of the failure of the singular system components was given according to the stress-strength interference theory and the load distribution of the component withstand. The dynamic reliability prediction model of the repairable k/n system was established by using probabilistic differential equations and by the repairable system components moving in reliable and failure. The equation was solved and their answers were shown to give the precisely k when the k would be determined. The model shows accuracy and feasibility by analysis of the example.

Key words: repairable, k/n voting system, dynamic reliability, life situation, prediction model, simulation
