从组成关联设备系统单元间3种关联关系(直接关联无作用、直接关联单向作用、直接关联相互作用)出发,将组成设备系统的单元作为节点、单元之间的作用关系作为节点之间的边,构建微观至宏观的系统可靠性网络模型;分析不同关联关系下和不同寿命分布下子系统可靠性的形式化描述及其计算方法,并通过实例进行了验证。研究表明,本文提出的方法可为关联系统单元间作用关系复杂且寿命分布不同的系统可靠性计算提供一种新的研究思路。
從組成關聯設備繫統單元間3種關聯關繫(直接關聯無作用、直接關聯單嚮作用、直接關聯相互作用)齣髮,將組成設備繫統的單元作為節點、單元之間的作用關繫作為節點之間的邊,構建微觀至宏觀的繫統可靠性網絡模型;分析不同關聯關繫下和不同壽命分佈下子繫統可靠性的形式化描述及其計算方法,併通過實例進行瞭驗證。研究錶明,本文提齣的方法可為關聯繫統單元間作用關繫複雜且壽命分佈不同的繫統可靠性計算提供一種新的研究思路。

Starting from the angle of the three relationships of elements of the interconnected equipment system and taking the system elements as nodes and the interacted element relationships as the edges of nodes , the mi-croscopic to macroscopic network-based equipment systems reliability model was constructed . The formalized description and calculating method of reliability of subsystems under different relationships and different life-time distributions were given . The example of EMU served to verify the practicability of the model . The study indicates that the proposed method provides a new way of thinking for calculation of reliability of interconnected systems of complex interacted element relationships and different lifetime distributions .
