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.
