摘要 根据信息熵等效的折合原则和单元可靠性评定的基本原理,研究了基于信息熵法的和联系统可靠性综合问题,导出了不同和相同支单元组成和联系统时,单元试验信息熵法折合及系统可靠性信息熵法第一、二近似下限的基本模型,并通过实例说明了方法的具体应用。实例表明,熵法评定结果与传统方法的评定结果非常接近,满足一般工程要求。 Based on the conversion principle of information quantity equivalence and the fundamental theoretics of the unit reliability assessment, the basic assessment method for plus system reliability are stud- ied in this paper, the basic models of entropy method synthesis assessment for plus system reliability first and second approximate confidence lower limits are established, the examples are given to illuminate the application of the modes and the assessment results are satisfactory comparing with the traditional matrix methods.
