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-Monte Carlo simulation when the system reliability characteristics of each unit volume is known, but the reliability of the system is too complicated, difficult to establish accurate mathematical model of reliability prediction models are too complex or inconvenient applications are available stochastic simulation method to approximate calculation the expected value of system reliability. With the increase in simulation times, which is expected to gradually increase precision. As the need for a large number of repeated calculations, generally using the computer to complete. This document is used to solve the problem of queuing theory Hospital
