Purpose
Introduction to the 5 basic steps of model building using a single queue, single server system (post office).
Description
people arrive at a post office every 60 seconds, on average. The statistical probability distribution which best simulates the inter-arrival pattern is an exponential distribution with a location value of 0 and a scale value of 60.
the service time at the one and only service window in the post office is lognormal2(31, 3.1, 0.5) seconds.
if the queue for the service window exceeds 20 people, new arrivals are routed out of the model as “unhappy customers”.
Basic Steps of Modeling in FlexSim
- Create a layout using library objects
- Make port connections
- Edit the look and behavior of objects
- Compile and run the simulation
- View the results

模型 1
目的
通过排队、服务系统(邮局)学习建模的5个基本步骤。
描述
- 每60秒有一位客户到达邮局。模拟时间间隔的最符合的分布是指数分布[方差(location value)为 0 ,均值为(scale value)60)].
邮局服务窗口的服务时间为 lognormal2(31,3.1,0.5)秒。
- 如果服务窗口前排队的队列超过20个人,新到的人(unhappy customers),则会直接离开。
FlexSim 建模的基本步骤
-使用实体库中的实体创建布局
- 端口连接
- 编辑实体的外观和逻辑
-仿真的编译和运行
- 查看结果
希望大家独立完成此模型,可以把做好的模型截图和相应的设置截图发上来分享。
