蒙特卡洛模拟法是当系统中各个单元的可靠性特征量已知，但系统的可靠性过于复杂，难以建立可靠性预计的精确数学模型或模型太复杂而不便应用则可用随机模拟法近似计算出系统可靠性的预计值。随着模拟次数的增多，其预计精度也逐渐增高。由于需要大量反复的计算，一般均用计算机来完成。本文件用来求解医院排队论问题。
English Description：
Monte Carlo simulation method is that when the reliability characteristic quantity of each unit in the system is known, but the reliability of the system is too complex to establish an accurate mathematical model for reliability prediction, or the model is too complex to be applied, the estimated value of system reliability can be approximately calculated by random simulation method. With the increase of simulation times, the prediction accuracy increases gradually. Due to the need for a large number of repeated calculations, they are generally completed by computer.
