Model 4 concepts
Itemtypes
Push vs. Pull
The Bernoulli Distribution

Purpose
Learn how to use pull logic in defining routings based on a flowitem’s itemtype.
Description
Electronic components need to be tested after manufacture.
There are two types of components that arrive in a queue at random with the mix being 40% of one and 60% the other.
The inter-arrival time of components is exponential(0,30,1)
There are two testers for component 1 and three testers for component 2.  Components will go to the first available tester.
Testing times are all between 120 and 150 seconds uniformly distributed.
Questions & Bonus
Are all testers equally utilized?
Can you model this with push?
Try assigning colors to the itemtypes.

模型 4 – 概述
临时实体类型
推式 vs. 拉式
伯努利分布

目的
学习如何基于临时实体的类型使用拉式逻辑定义路线。
描述
电子组件在生产之后需要测试。
有两种类型的组件随机到达暂存区，比例是40%和60%
组件到达的时间间隔按照指数分布 exponential(0,30,1)
由两个测试员测试组件 1.三个测试员测试组件2.  组件将被送到第一个可用的测试员处。
测试时间为120-150秒之间，服从均匀分布。

问题
测试员的利用率相同吗?
这个模型可以用推式方式实现吗?
尝试设置实体类型的颜色。
