北戴河火车站售票系统仿真. 《建模与仿真》课程 姓名:王小刚 学号:1111028 北戴河火车站售票系统仿真 一、模型描述 1、 假设北戴河火车站有2个自动售票机机、1个网络购票取票机，1个成人票 窗口，1个学生票窗口，1个改签(退票)窗口。 2、 已知前往天津、北京、河北省内车票数量充足，绝大多数人直接在自动售票 机上购票，方便，高效;开往新疆、海南、云南等地的火车车票价格较高， 需要在柜台办理;取票，退票，改签业务在特殊窗口办理。由于取票机不能 取学生票，所以使用人数仅针对成人票的业务办理，使用人数较少。 3、 票价<100的建议在自动售票机上完成，300<票价<600,或>1000的建议在人 工售票窗口购票，学生票仅能在学生票窗口购得。 4、 顾客会选择最短队列的机器或柜台。 5、 乘客到达时间间隔服从参数为2的泊松分布。 6、 乘客购票花费金额服从正态分布N(600，100)，正态分布N(3000，500)。 在自动售票机上操作时间服从均匀分布UNIFORM(2，5)的随机分布，自动取票机的时间服从均匀分布UNIFORM(4，10)，柜台售票的时间服从均匀分布UNIFORM(3，7)，柜台取票时间服从均匀分布UNIFORM(6，9)，其他业务办理时间服从均匀分布UNIFORM(5，25)，退票、改签业务办理时间服从均匀分布UNIFORM(10，40)。 二、模型归档 1、模型逻辑结构图 2、模型细节 MODEL INFORMATION: Model Name: 北戴河火车站售票系统 Model Title: Base Model.
