| 摘 要： | 引入信息理论， 利用信息量的可加性特性及总信息量相等的原则进行试验信息的折合， 并与可靠性工程理论相结合， 推导了相同成败型单元（服从二项分布） 组成系统时单元试验信息熵法折合的通用公式； 根据单元可靠性评定的基本原理， 提出了系统可靠性熵法评定近似下限的基本模型； 通过实例讨论了系统可靠性熵法评定的具体应用， 其结果相当令人满意。

| Abstract: | The reliability assessment of the unit system is the most important content in the reliability assessment of complex systems The general calculation formulae of the entropy method synthesis on the systems consisting of identical success failure binomial units are derived by use of the addible characteristics of information quantity and the principle of equal information quantity The general model of the entropy approximate lower limits for the system reliability is gave according to the fundamental method of the unit reliability assessment The application of the assessment method is analyzed by way of examples The assessment results are very satisfactory The assessment method proposed can be popularized to the systems which have a fixed reliability structural model |
