简便食堂

This paper use Monte Carlo method in Excel to dynamically simulate the service status and waiting time of university dinning room windows. This method based on "random number" is usually used to solve practical problems with complicate probability distribution. This paper simulates one window and two windows of a dinning room separately. Through 1000 simulations and statistic analysis to get conclusions, thus bring up reference frame to decision maker.

用蒙特卡洛法在Excel上对大学食堂的窗口服务状态和排队等待问题进行模拟，分别模拟了食堂在开设一个窗口和两个窗口的情况下学生的排队问题，通过1000次模拟的统计分析得出，该方法具有简便、易行、实用性强的特点，为决策者提供了参考依据。
