This fourth post in the series on the inner workings of the Amazon Fulfillment Center will continue to look at the outbound material flow, including pack, SLAM, and the loading of the trucks. In the next and last posts, I will also look at the software behind it as well as some surrounding processes.
This is the third post on my series on the inner workings of the Amazon Fulfillment Center. In this post I start with the highly interesting process of the outbound value stream (i.e., how the goodies go from storage to your door). Since this is the core process, the next post will continue this outbound value stream.
This is the second post in my series on the inner workings of Amazon Fulfillment Centers. In this post I will look at the typical layout of the fulfillment centers and start with the inbound value stream. After all, while we all are looking forward to getting stuff from Amazon, Amazon first has to get the stuff from somewhere else.
Recently I had the chance to visit two Amazon Fulfillment Centers to take an in-depth look at their inner workings. While many articles about Amazon go over the basics, I will give you a deep dive into the workings of their fulfillment centers. Due to the amount of information, I divided the content across a series of posts. In this first post I will go through their general layout as well as their Kiva robotics system.

FIFO lanes are a common and easy way to manage material flow. However, sometimes there is not enough space to make a long FIFO lane. In this case the FIFO lane is often split into multiple sub-segments. This post looks at how to maintain strict (or strong) FIFO in such parallel FIFO lanes. Continue reading Maintaining Strong FIFO in Parallel FIFO Lanes
In my last post I looked at delivery sequences like FIFO, LIFO, etc. This second post looks at simple production sequences where you do have to deal with limited production capacity. If you cannot make everything at once, you need a sequence in which you process the parts. Continue reading Production Sequences: FCFS, EDD, and Others
Sometimes, when you need a part or product from your inventory, you may have more than one item in stock. Which one do you pick? In this blog post I want to present a few strategies for choosing which item to take. The most famous one is FIFO, but there are more options available. In my next post I will present similar strategies if you need to start production before the item becomes available. Continue reading Delivery Sequences: FIFO, LIFO, and Others
In my previous posts I explained how POLCA works and discussed the pros and cons of POLCA. In this post I will explain how to calculate the number of POLCA cards. While POLCA is overall a feasible method, I do have some critical comments on the method to calculate the number of POLCA cards. Continue reading Calculating the Number of POLCA Cards
