摘要 概率分布函数的选择对于蒙特卡罗模拟风险分析结果的准确性以及不确定性有较大的影响,往往直接影响到风险分析结果的有效性,是进行蒙特卡罗模拟分析必须要解决的问题。笔者结合国外相关文献的成果,说明了选择什么样的概率分布描述被分析对象的不确定性最合适,应用示例也揭示了概率分布函数对蒙特卡罗模拟分析结果不确定性所造成的影响。 The selection of probability distribution function (PDF)seriously influences the accuracy and uncertainty of Monte Carlo simulation risk analysis,and directly impacts the effectiveness of risk analysis.Referring to foreign literatures, this paper introduces how to select a better PDF for application. An example is taken to show the influence of PDF on the uncer- tainty of Monte Carlo simulation analysis results.
