在损失分布法下估计操作风险资本需要评估总（复合）损失分布，这是风险理论中的经典问题之一。封闭形式的解决方案不适用于操作风险中通常使用的分布。然而，利用现代计算机的处理能力，这些分布可以用数值方法精确地计算出来。本文综述了可成功用于计算总损失分布的数值算法。重点介绍了Monte Carlo法、Panjer递推法和Fourier变换法，并进行了比较。同时，对几种基于矩匹配的闭式逼近和重尾分布的渐近结果进行了评述。

英文摘要：
  Estimation of the operational risk capital under the Loss Distribution Approach requires evaluation of aggregate (compound) loss distributions which is one of the classic problems in risk theory. Closed-form solutions are not available for the distributions typically used in operational risk. However with modern computer processing power, these distributions can be calculated virtually exactly using numerical methods. This paper reviews numerical algorithms that can be successfully used to calculate the aggregate loss distributions. In particular Monte Carlo, Panjer recursion and Fourier transformation methods are presented and compared. Also, several closed-form approximations based on moment matching and asymptotic result for heavy-tailed distributions are reviewed.
