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.
Yeah, I've read that fulfulment warehouses are a terrible place to work: http://www.alternet.org/story/154344/what_happened_when_i_got_a_job_at_a_soul-crushing%2C_abusive_warehouse

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.

Not true. They bought Kiva. It probably takes a while before they work out the changes needed and roll that out.
As for humans getting rest, in many countries if you end up without a job and are not in the "ruling caste" the rest of the people don't seem to think you deserve to get any $$$$ for "resting" aka "doing nothing productive".
Careful for what you ask for, you may get it.
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...
As others have noted, Amazon purchased Zappos which utilizes Kiva in their warehouses. I expect Amazon to adapt Zappos models more than Amazon to migrate Zappos to their model. Every time a robot/computer replaces a human (been going on for 40 years), the fractional replacement human is a high skilled person than the multiple people they replaced. Think stocking -- the programmer costs a lot more and requires a lot more education than the human picker -- but the programmer's work can be deployed without limitations to service 6 billion people (and more later).
The first world societies have to understand real soon that they need to figure out what to do with the jobless masses with IQs under 110 in fifty years. The answer can't be "pay them to breed more crack babies", the answer has to be "each generation values breeding less and eduction more" - or expect their economy to sink under the economic sea like most of the PIGS probably will.

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.

"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.
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.

Well, the problem of "masses" is taking care of itself. No need for government policy there; market forces are driving population growth down.
As to the "IQ under 110," there are lots of productive and necessary jobs that can't easily be automated. It's going to be a long time before a robot can cook a gourmet meal or repair a leaky faucet or give me a good haircut.
One doesn't need to be educated or even terribly smart to be a productive member of society. One just needs a work ethic.
