| 摘 要： | 通过引入位置参数,建立了能够同时描述浴盆曲线失效率和最大安全寿命的广义Weibull分布模型族,进而采用秩分布理论给出确定该寿命分布族置信限估计的参数化方法。具体分析了目前广泛应用的一种广义Weibull分布,导出该模型参数的置信区间估计与分布函数的置信上、下限曲线函数关系式。文中还进行了模拟验证与实例对比分析。

| Abstract: | The generalized weibull distribution(GWD) families contained location parameter are proposed,which can analyze the life data with both the bath-curve failure rate and maximum safety life better than the traditional GWD.The parameterized method of confidence limits is established based on the theory of rank distribution.For a widely used GWD,one-sided confidence and two-sided confidence interval of both parameters and distribution curves are discussed in detail. In addition,examples of both simulation and comparison are given at last. |
