Inside an Amazon Warehouse
redletterdave writes "In each one of Amazon.com's 80 fulfillment centers around the globe, Amazon relies on barcodes and human hands rather than robots or automation to find and ship the proper items in a quick and efficient manner. Without robots, Amazon utilizes a system known as 'chaotic storage,' where products are essentially shelved at random but are tagged with barcodes to be scanned at every step of the ordering, selection and shipping process. The real advantage to chaotic storage is that it's significantly more flexible than conventional storage systems. If there are big changes in a product range, the company doesn't need to plan for more space, because the products or their sales volumes don't need to be known or planned in advance if they're simply being stored at random. Free space is also better utilized in a chaotic storage system, and it's also a major time saver to not organize products as they come in. This system is the true key to Amazon.com's success in online retail."
I utilize a chaotic storage system.
It sounds like someone needs to run a defrag on those warehouses.
May be nice if that site works with the latest Firefox, too... been a while since I had an issue with a site just not working.
My room is a disaster. My bed isn't made, nobody can find anything in here but me, and I have a couple bras right now hanging on the lamp to dry because there's nowhere else to put them. According to this article, I should be a major, successful retail vendor. So if that's true, instead of expecting me to be a billionaire or the President, my mom keeps telling me that at this point, she'd be happy if I'd just breed?

If you've ever worked at Wallmart or I guess any of the other major supermarkets, they do the same thing. Store stuff whereever and track where it is. So it might be organized on the computer, but in the storerooms its real-world location bears no relation to it's computerized structure.
Again for the same reason, seasonality and holidays etc. mean the sales are not constants and stocks of different items vary, and with small space at the supermarket for storage, it doesn't make sense to dedicate empty space to storing *potential* stuff.
But hey, perhaps Bezo's plans to patent it, like one click ordering. So he's pretending it's a new thing.
A friend of mine has a small business selling specialized shoes, and needs a new inventory system. Quickbooks just doesn't cut the load and such large inventories. Ideally, it should be an open source solution, either LAN or web-based, with very comprehensive inventory management and customer relationship management, barcode reading/printing, possibly unique ID (serial number) generation, and ideally some accounting/quickbooks integration.
Has anyone dealt with such systems? Any recomendations? Many thanks.
So, Amazon is refusing to invest in robots to do this repetitive work? Instead, they employ humans to perform mind-numbing running all over the place to fetch products and fill shipping boxes. Don't you think a company of Amazon's size should spend some of those billions on some modern industrial robots so that the humans can get a rest?

We could learn off Amazon for our own computer file systems. A metadata/database filesystem where everything is stored all in one folder (rather than organized into directories) would save everyone so much time. The barcode would be replaced by 'tags' or metadata. Popular and recent tags could be accessible via a dropdown. Hunting for files, reorganization, deciding where to store files, becomes suddenly much easier.

Don't we have something called the world wide web that's a bit like that now?
N.B. this user is far too lazy to write a witty and intelligent sig.
Chaotic storage works because the barcode of each shelved item is scanned together with the barcode of its shelve, so that the computer can later on tell the humans where to find the stuff for a certain order.
Apparently there is no reason why this wouldn't work with robots. Apparently robots are still to expensive or not smart (in terms of physical skills) enough.I wonder when we'll see Amazon experimenting with robots.

I use very much the same system in my room. Worked fine when I was young, had a brilliant memory and knew where everything was. Now I'm at the "get off my lawn" age, I forget where I put things within two minites of putting them down, Spend half my life looking for things.
Would get myself organised, but at my age the payback time is probably not worth the time spent doing it.

So Amazon is defragmenting their fulfillment centers :-)
I work in a fulfilment centre myself, and i can say that while the storage is very efficient, as mentioned, the algorithms that rout pickers to collect the various items leave a lot to be desired. Its all well and good having ingenious storage systems, but if you have to spend 2 minutes walking to a particular shelf location to collect item X passing 8 different bins containing item X along the way, it wastes huge amounts of time and effort. For example, our fulfilment centre is LOSING $250000 due simply to pick-routing inefficiencies...
>This system is the true key to Amazon.com's success in online retail.
I always believed it was the fact they didn't make any profits during at least 7 years (from 1994 to >2001. This is a very long time loosing money but suffisient to kill any concurrency.
Also forgot how to spell minutes :)
I also pretty much use the quasi-random organization technique. If I use it regularly, I know where it is. If I need it badly, I'll search for it. Other cases, demand the other party produce it.

The problem for me started when I switched from having "my room" to having "my house" and sharing it someone else who also calls it that, with every right. And this someone else also spends more time there than I do, and likes to rearrange "my stuff" ...so ...yeah
Amazon announces that, after a century of tweaking about, they have arrived at a self-replicating fulfillment warehouse system.
Everything is on 23 pairs of rows. The tips of the 23 rows of two warehouses break off intermittently, and circulate freely on the roadways disguised as traffic.
If any two sets of 23 show up in a fulfillment center parking lot and collide, a new fulfillment center is 'conceived', and 'gestates' for a few seasons before making a the shortest possible journey to a new location, where it starts doin' its thang'. A shocking amount of the row storage is metadata, such that a warehouse query fails outright or returns a product at roughly ludicrous speed. "Yeah, it's kind of a b-tree on Brawndo," said Dr. Joey "TT" Torvalds-Tridgell, the 800lb Brain of Amazon.
In other news, Walmart President Sanger is seeking to legalize the abortion of this burgeoning threat, saying that wanton murder, too, is a form of capitalism.

Just did the upgrade from 16.0.2 to 17, and now it works.
Since there's no organizational scheme, I assume that the human workers have to be told turn by turn where to go? That for anything but an item that they picked up recently, a human worker would need to be told where exactly to go to pick up the nearest item X. And even if one of the human workers did remember the last place they saw X, that spot probably is not the closest instance of X. This kind of storage scheme means that the human workers are simply meat waldos serving the computer software that runs the place.
Just imagine, a girl with all the bits labeled with barcodes so you can scan them and google the manual for it! And easily order replacement parts.

They've been doing "random shelving" of their items since their very first fulfillment center that wasn't Jeff Bezos's garage. It isn't particularly new, revolutionary, or a big secret.
This is an old and proven way to manage shelf space in a warehouse. This is no news and whoever wrote this article doesn't know much about logistics...
"This system is the true key to Amazon.com's success in online retail". That, and not paying any tax.
The second package had the same book in it.
So did the third.
It turns out that for some reason, possibly because they were part of the same product line, these two books were assigned the same Amazon-internal barcode. Because of this I never got the book that was ordered, but instead ended with two copies of the book that was mistakenly sent, and a credit for the cost of the original order.
What might have been an easily remedied issue, had storage followed a logical pattern and the fulfillment person given enough autonomy to detect and solve the problem, ended up taking months to get to the bottom of.

Since there's no organizational scheme, I assume that the human workers have to be told turn by turn where to go?
There is an organizational scheme, it's just not by by product and workers will be told where to go regardless of what storage system the company uses. I implemented a version of this about 10 years ago in our warehouse for an auction company I owned. Basically you build a warehouse with identifiers on the shelving system. Then you assign a random and (this is the important bit) uniformly distributed code to each box/pallet/SKU that you store. You can't tell where a product is by the product, you have to look up the location in the computer but after that it's easy to find. This system works really well when you have a wide array of rapidly changing merchandise that you can't predict arrival times or quantities for. Amazon would be a great fit for a warehousing system like this.
This kind of storage scheme means that the human workers are simply meat waldos serving the computer software that runs the place.
That's true for pretty much all warehouses regardless of organizational scheme. Once you get to a warehouse of any size you have to have a computer to direct where to find merchandise to pick to an order. Even if the worker knows where to get it they still will need direction from the computer on quantities to pick.
I know Amazon has take some great strikes in the shipping aspect of prime. They have warehouses just for staging then they have warehouses all around the world the Prime Shipping is great but it was a major under taking in the fulfillment center part of there operation.

But when you start adding foodstuffs and chemicals, you'll run into complications and be forced to keep them separate by legal regulation. That's probably part of the reason Amazon's so slow/not getting into foodstuffs.

The article slideshow isn[t working for me. Some photos from an Amazon warehouse were posted on reddit the other day. Here are those photos: http://imgur.com/a/q1WIO.
Homer no function beer well without.
I just read this article about how GAP and Zappos are using Kiva robots in their warehouses which makes a nice contrast. http://www.wired.com/wiredscience/2009/01/retailrobots/
As far as I can tell the Kiva warehouses could probably be said to use some form of cahotic storage too. The advantages they cite to using robots are: much higher productivity, less walking for employees, safer and more ergonomic environment, less 'shrinkage' (theft) due to most of the warehouse being robot-only, lower power usage due to greatly reduced need for climate control and lighting (again thanks to the large robot-only area) and lack of conveyor belts running all the time.
That said the Amazon warehouse stores much more diverse merchandise in terms of format, packaging type and weight. Also it has multiple stories, much higher shelves in some areas and generally seems much larger. That may have an impact on whether the Kiva robots would be workable. Or maybe it just means some adjustments would be needed.
I work at a fulfillment warehouse and it's actually a great place to work. Granted, I'm an office geek but we take care of our hourly workers very well. Everything we do to modify the shipping process (basically an assembly line) is to make things not only quicker but easier on the workers as well. Everyone is encouraged to make contributions to the team and there is plenty of opportunity to move up, get raises etc. Benefits are excellent and the pay is good. Nobody gets chewed out for making a mistake, we just look at the process itself and how we can prevent such a mistake in the future by doing things differently. Why would you run it any other way? The people packing the boxes can make or break the place. It pays to keep them happy and caring about their jobs.
It helps to land clients that ship 1 of item X to 10,000 different addresses on a bi-weekly basis ;)
In an Amazon-like model, orders are essentially random. We have processes to handle both and the "random" orders take up way, way more time and effort than the "batch" orders. Something crazy like 100 times as much effort. If you have the financial wiggle room, turn away the random clients and go after someone that has one or two products and a million customers.

I think real chaos could be introduced if someone were to swap locations of random items after the initial location was entered on the computer.
I'm not saying it's not an interesting, non-intuitive way of shelving goods. (At least its non-intuitive if you don't design DC's for a living) What I am saying is that it's not "the true key to Amazon's long-term success" like the summary stated. It wouldn't be an exaggeration to state that if Amazon had decided to organize their goods like a library, they'd have gone bankrupt a VERY long time ago. Pretty much EVERY retail-order DC of any size shelves goods this way, and has done so for quite some time; Amazon certainly wasn't the first.
What is a real shame is that Amazon HAS done very innovative and unique stuff with order assembly (bringing the items together in a multi-item order) in their warehouses, yet the article focused solely on the one thing that is utterly non-unique to Amazon.
This explains why I ordered Firefly and Serenity and received two random country music CDs instead!
It actually worked out pretty well. At the beginning of each 4-hour shift, you get a series of pull tags, put them in order by aisle and shelf, then just take a cart along and do a single circuit of the warehouse, pulling the parts in order of the tags.
I think they did make some attempt at keeping things in specific order, but since it changed so much it didn't really make any difference. As long as the computer knew where everything was, it worked.
No running back and forth or criss-crossing the warehouse needed. With a modern computer system, it could be even more efficient. The computer can give you the tags in order, and different people could take different parts of the warehouse to speed things up even more.
If the masses can keep you down, you're not the Ubermensch.

As posted earlier, Chaotic storage is great for automated pick lists and the picking is for low volume or high volumes of items.
The reason is apparent. With low volumes, the device goes to the row, aisle bin, and selects the item, goes to the next place, and returns with the goods.
At high volume, (many many picks), the system can reorder the picking to optimise the routes within that warehouse area. Picker units do not cross zones.
If an item is very popular, the idea is to move it closer to the shipping docks where human hands can take it, package, and ship it after invoicing.
Like other picklist systems, the orders are best handled in next day daily batches. Immediate day delivery adds cost. With batching, the sorting for picking for air, road, and rail delivery can be performed at a first level, and then by location within the warehouse as the second level sort.

Not exactly a new idea. Perhaps surprising that they rely on it with manual picking, but since a lot of their orders are timely, the "most recent" stuff is all together still on the pallet it arrived on. And as noted by others, as long as the pick list is arranged in physical order by the inventory system, there's not much lost time.
