REALLY simulating the Supply Chain Block 1-4

I have seen a couple people stall when facing the challenge of simulating a real picking operation. There are plenty of ways to organize both the resources and the picking tasks. These configuration decisions respond to product size, weight, order profile, frequency, complexity and size layout, picking technology, levels of automation and other factors.


Out of the many order processing activities, picking receives most of the attention. Why?

  1. In the picking process clerks will handle pallets, cases, inner packs displays and even units.

  2. According to Bartholdi, Frazelle and several other authors from 40% to 60% of the Distribution Center's workfoce, is spent in picking, and most of the pickers’ time is used in traveling.

  3. Finally, picking mistakes are not trivial, since it is highly possible they will reach the customer.

Today we will create a forward picking area (FPA), replenish it with a pull system and assure that our FPA is scalable.


By using pull and pull requirement, you can respect the locations assigned to each SKU in your FPA.

Today's key concepts:

  1. PULL AND PULL REQUIREMENT

  2. LOADING AN AUTOCAD LAYOUT

  3. PREPARING THE AUTOCAD FILE TO BE LOADED

  4. CREATING FLOWITEMS FROM A QUEUE

Next we will begin the construction of the decision-making processes intrinsic to picking, replicate an order profile through a statistical distribution and handling of process exceptions

(there are so many of them :P ).


This is REALLY simulating the Supply Chain, your best source for simulation tutorials and references. I am Enrique Elizaga head of simulation projects at Supply Chain Institute and I'm very excited to help you become a simulation expert!
