它使用随机数5生成器通过重复地根据不确定变量的概率分布采样来生成模型的多重情境。
It typically USES random number 5 generators to generate multiple scenarios of a model by repeatedly sampling values from the probability distributions for the uncertain variables.
我也赞同里索对客观概率论的批评，有人企图用它来减少现实世界的不确定性，使其趋近于确定的世界。
I would also endorse Rizzo's critique of attempts to use objective probability theory as a way of reducing the real world of uncertainty to certainty equivalents.
当概率分布未知时，就存在不确定性。
Uncertainty occurs when the probability distribution is unknown.
