摘要：To solve the complex reliability analysis problem of basic GO methodology, a UGF-GO methodology based on the universal generating function (UGF) and GO methodology is proposed to analyze the reliability of complex multi-state system. The proposed methodology can be used to analyze the structure relation among various operators in GO chart and obtain the system reliability based on the corresponding universal generating function (UGF). The UGF-GO methodology can not only reduce the computational complexity of GO chart, but also simplify the correction process of shared signals. The simplicity and effectiveness of UGF-GO methodology are proved by comparing the reliability analyses of UGF-GO methodology and probability formula algorithm. The UGF-GO methodology is applied to analyze the degradation reliability of an aircraft power supply system. The simulated results show that UGF-GO methodology can be used completely to analyze the reliability of system with degradation behavior from failure mechanism to degeneration modeling. © 2020, Editorial Board of Acta Armamentarii.
