摘　　要：针对概率本身的灰色不确定性 ,基于概率论和灰色系统理论方法 ,定义了灰色概率、灰色概率的灰度、灰色概率分布、灰色概率密度、灰色期望及灰色方差等基本概念 ,介绍了可以用于灰色概率分布参数估计的DDirecting towards the grey uncertainty of probability itself, the concepts of grey probability, the grey degree of grey probability, grey probability distribution, grey probability density, grey expectation and grey variance are defined based on the theory of probability and grey system approach. The Dempster-Shafer theory and Dempster's and Shafer's approachs to inference, that can be used to estimate the parameters of grey probability distribution, are introduced.
