Results prove that worst-case or root-sum-square analyses are not adequate to predict probable performance accurately.A Monte Carlo analysis must be performed.

【文献摘要】A numerical analysis indicates that tolerance stackup effects in free-space optical interconnects are significant even for short systems containing few components.

Methods In accordance with Monte Carlo method and measures of disproportionality theory, simulate the adverse drug reaction surveillance data by the random mode.

方法参照罗方法基本思想，基于不相称性测定论，采用随机模拟的方法对药物不良反应监测数据进行模拟。
