研究了将向量通用发生函数理论用于对考虑多性能参数的复杂热力系统进行可用度分析。定义了设备性能的向量通用发生函数,建立了热力系统可用度分析的向量发生函数算法模型,给出了多状态设备状态概率的计算方法。通过对系统内部多因素退化规律的随机模拟,对复合因素影响下的多性能参数热力系统可用度进行了分析计算。实例研究表明,传统的基于二态理论的系统可用度评估结果偏保守,而基于多状态系统理论考虑参数失效的系统可用度评估结果更能反映系统的实际使用特性。
研究瞭將嚮量通用髮生函數理論用于對攷慮多性能參數的複雜熱力繫統進行可用度分析。定義瞭設備性能的嚮量通用髮生函數,建立瞭熱力繫統可用度分析的嚮量髮生函數算法模型,給齣瞭多狀態設備狀態概率的計算方法。通過對繫統內部多因素退化規律的隨機模擬,對複閤因素影響下的多性能參數熱力繫統可用度進行瞭分析計算。實例研究錶明,傳統的基于二態理論的繫統可用度評估結果偏保守,而基于多狀態繫統理論攷慮參數失效的繫統可用度評估結果更能反映繫統的實際使用特性。

Vector-universal generating function was presented to analyze the availability of thermodynamic system with multiple performance parameters .Vector-universal gen-erating function of component’s performance was defined ,the arithmetic model based on vector-universal generating function was derived for the thermodynamic system ,and the calculation method was given for state probability of multi-state component .With the stochastic simulation of the degeneration trend of the multiple factors ,the system availability with multiple performance parameters was obtained under composite factors . It is shown by an example that the results of the availability obtained by the binary availability analysis method are somewhat conservative , and the results considering parameter failure based on vector-universal generating function reflect the operation characteristics of the thermodynamic system better .
