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.
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?

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

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...
It's likely mostly the physical skill of opening a wrapper and taking a book out of it. Or worse, some odd shaped item. That's stuck in the tight wrapper.
The first (and only photo visible to me) on that that site showed a bunch of shipping pallets aligned haphazardly with cartons stacked on top of them. Assuming one item per pallet, you go find the pallet (easy), then find which carton is currently open already (harder), then manouvre your arms and hands to take an item out of the carton (that's the tough one - especially the getting your fingers around it part), and place it in your shopping trolley or whatever they use there (easy again).
Finding and scanning bar codes may also be tricky, as they're likely not on fixed locations.
Current robots work where a blind man could work. They are as good as blind, after all. And need to know exactly where to find a product, and how to take one and only one. That's not easy with all those odd shaped, and constantly changing products.
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.
