For the next few minutes
I want to talk to you about...
-
or share with you a
breakthrough new approach
-
for managing items of
inventory inside of a warehouse.
-
We're talking about a Pick,
Pack and Ship setting here.
-
So as a hint,
-
this solution involves
hundreds of mobile robots,
-
sometimes thousands
of mobile robots,
-
moving around a warehouse.
And I'll get to the solution.
-
But for a moment, just think
-
about the last time
you ordered something online.
-
You were sitting
on your couch
-
and you decided that you
absolutely had to have this red t-shirt.
-
So click you put it
into your shopping cart.
-
And then you decided
that green pair of pants
-
looks pretty good too, click.
-
And maybe a blue
pair of shoes, click.
-
So at this point you've
assembled your order.
-
You didn't stop to think
for a moment that
-
that might not be a great outfit.
-
But you hit
Submit Order.
-
And two days later, this package
shows up on your doorstep.
-
And you open the box and like
Wow, there's my goo.
-
Did you ever stop to think about
how those items of inventory
-
actually found their way inside
that box in the warehouse?
-
So I'm here to tell you
it's that guy right there.
-
So deep in the
middle of that picture
-
you see a classic
Pick Pack Worker
-
in a distribution or
order fulfillments setting.
-
Classically these pick workers
will spend 60 to 70% of their day
-
wandering around
the warehouse.
-
They'll often walk
as much as 5, 10 miles
-
in pursuit of
those items of inventory.
-
Not only is this an
unproductive way to fill orders,
-
it also turns out to be an
unfulfilling way to fill orders.
-
So let me tell you where I
first bumped into this problem.
-
I was out in the Bay area
in 1999-2000, the dot com boom.
-
I worked for a fabulously
spectacular flame out called Webvan.
-
(Laughter)
-
This company raised hundreds of
millions of dollars with the notion that
-
we will deliver
grocery orders online.
-
And it really came down to the fact
that we couldn't do it cost effectively.
-
Turns out e-commerce was something
that was very hard and very costly.
-
In this particular instance we were trying
to assemble 30 items of inventory
-
into a few totes, onto a van
to deliver to the home.
-
And when you think about it,
it was costing us $30.
-
Imagine, we had an
89-cent can of soup
-
that was costing us $1 to
pick and pack into that tote.
-
And that's before we actually
tried to deliver it to the home.
-
So long story short,
during my 1-year at Webvan,
-
what I realized by talking to
all the material-handling providers
-
was that there was no solution designed
specifically to solve each base picking.
-
Red item, green, blue, getting
those 3 things in a box.
-
So we said, you know, there's just
got to be a better way to do this.
-
Existing material handling
was setup to pump
-
pallets and cases of
goo to retail stores.
-
Of course Webvan went out of business
and about a year and a half later,
-
I was still noodling on this problem.
It was still nagging at me.
-
And I started
thinking about it again.
-
And I said "Let me just focus briefly
on what I wanted as a pick worker."
-
What my vision for
how it should work.
-
(Laughter)
-
I said "let's focus
on the problem."
-
I have an order here and what
I want to do is I want to put
-
red, green and blue
in this box right here.
-
What I need is a system where I put out
my hand and poof!
-
the product shows up
and I pack it into the order,
-
and now we're thinking,
-
"this would be a very operator-centric
approach to solving the problem.
-
This is what I need. What technology
is available to solve this problem?"
-
But as you can see, orders can come
and go, product can come and go.
-
It allows us to focus on making the
pick worker the center of the problem,
-
and providing them the tools to make
them as productive as possible.
-
So how did I
arrive at this notion?
-
Well, actually it came from
a brainstorming exercise,
-
probably a technique
that many of you use,
-
It's this notion of
testing your ideas.
-
Take a blank sheet of course,
-
but then test your ideas
at the limits. Infinity, zero...
-
In this particular case, we
challenged ourselves with the idea:
-
wWhat if we had to build a
distribution center in China,
-
where it's a very,
very low cost market?
-
And say, labor is cheap,
land is cheap.
-
And we said specificall:
-
"what if it was zero dollars
an hour for direct labor
-
and we could build a million
square foot distribution center?"
-
So naturally that
led to ideas that said:
-
"Let's put lots of people
in the warehouse."
-
And I said: "hold on,
zero dollars per hour,
-
what I would do is "hire"
-
10,000 workers to come to the
warehouse every morning at 8:00 am,
-
walk into the warehouse and
pickup 1 item of inventory
-
and then just stand there.
-
So you hold Captain Crunch,
you hold the Mountain Dew,
-
you hold the Diet Coke.
-
If I need it, I'll call you,
otherwise just stand there.
-
But when I need Diet Coke and I call
you guys talk amongst yourselves,
-
Diet Coke walks up to the front,
pick it, put it in the tote, away it goes."
-
Like wow, what if the products
could walk and talk on their own?
-
That's a very interesting
very powerful way
-
that we could potentially
organize this warehouse.
-
So of course,
labor isn't free,
-
on that practical
versus awesome spectrum.
-
(Laughter)
-
So we said mobile shelving.
We'll put them on mobile shelving.
-
We'll use mobile robots and
we'll move the inventory around.
-
And so we got underway on that and
then I'm sitting on my couch in 2008.
-
Did any of you see the Beijing
Olympics, the opening ceremonies?
-
I about fell out of my
couch when I saw this.
-
I'm like, that was the idea!
-
(Laughter and Applause)
-
We'll put thousands of people on
the warehouse floor, the stadium floor.
-
But interesting enough, this
actually relates to the idea
-
in that these guys were creating some
incredibly powerful impressive digital art,
-
all without computers,
I'm told,
-
it was all peer-to-peer
coordination and communication.
-
You stand up,
I'll squat down.
-
And they made
some fabulous art.
-
It speaks to the
power of emergence
-
in systems when you let things
start to talk with each other.
-
So that was a little
bit of the journey.
-
So of course, now what became
of the practical reality of this idea?
-
Here is a warehouse.
-
It's a pick, pack and ship center
that has about 10,000 different SKU's.
-
We'll call them red pens,
green pens, yellow Post-It Notes.
-
We send the little orange robots
out to pick up the blue shelving pods.
-
And we deliver them
to the side of the building.
-
So all the pick workers now
get to stay on the perimeter.
-
And the game here is
to pick up the shelves,
-
take them down the highway and
deliver them straight to the pick worker.
-
This pick worker's life
is completely different.
-
Rather than wandering around
the warehouse, she gets to stay still
-
in a pick station like this
-
and every product in the
building can now come to her.
-
So the process
is very productive.
-
Reach in, pick an item,
scan the bar code, pack it out.
-
By the time
you turn around,
-
there's another product there
ready to be picked and packed.
-
So what we've done is take
out all of the non-value added
-
walking, searching,
wasting, waited time,
-
and we've developed a very
high-fidelity way to pick these orders,
-
where you point at it with
a laser, scan UPC barcode,
-
and then indicate with a light
which box it needs to go into.
-
So more productive, more
accurate and it turns out
-
it's a more interesting office
environment for these pick workers.
-
They actually complete
the whole order.
-
So they do red, green and blue
not just a part of the order.
-
And they feel a little bit more
in control of their environment.
-
So the side effects
of this approach
-
are what really surprised us.
-
We knew it was going
to be more productive.
-
But we didn't realize just how
pervasive this way of thinking
-
extended to other
functions in the warehouse.
-
But what effectively this approach
is doing inside of the DC
-
is turning it into a massively
parallel processing engine.
-
So this is again a
cross fertilization of ideas.
-
Here's a warehouse
and we're thinking about
-
parallel processing
supercomputer architectures.
-
The notion here is that you have
-
10 workers on
the right side of the screen
-
that are now all independent
autonomous pick workers.
-
If the worker in station 3 decides
to leave and go to the bathroom,
-
it has no impact on the
productivity of the other 9 workers.
-
Contrast that, for a moment, with the
traditional method of using a conveyor.
-
When one person
passes the order to you,
-
you put something in
and pass it downstream.
-
Everyone has to be in place
for that serial process to work.
-
This becomes a more robust
way to think about the warehouse.
-
And underneath the hoods gets
interesting in that we're tracking
-
the popularity
of the products.
-
And we're using dynamic
and adaptive algorithms
-
to tune the floor
of the warehouse.
-
So what you see here potentially
the week leading up to Valentines' Day.
-
All that pink chalky candy has
moved to the front on the building
-
and is now being picked into a
lot of orders in those pick stations.
-
Come in two days after Valentine's Day
and that candy, the leftover candy,
-
has all drifted to the
back of the warehouse
-
and is occupying the cooler
zone on the thermo map there.
-
One other side effect of this
approach using the parallel processing
-
is these things can
scale to ginormous.
-
(Laughter)
-
So whether you(re doing
2 pick stations, 20 pick stations, or
-
200 pick stations, the
path planning algorithms
-
and all of the inventory
algorithms just work.
-
In this example you
see that the inventory
-
has now occupied all the
perimeter of the building
-
because that's where
the pick stations were.
-
They sorted it
out for themselves.
-
So I'll conclude with
just one final video
-
that shows how
this comes to bear
-
on the pick worker's actual
kind of day in the life of.
-
So as we mentioned, the process is
to move inventory along the highway
-
and then find your way
into these pick stations.
-
And our software in the background
-
understands what's going on
in each station,
-
we direct deposit
across the highway
-
and we're attempting to
get into a queuing system
-
to present the work
to the pick worker.
-
What's interesting is we can even
adapt the speed of the pick workers.
-
The faster pickers get more pods
and the slower pickers get few.
-
But this pick worker now is
literally having that experience
-
that we described before.
-
She puts out her hand.
The product jumps into it.
-
Or she has to reach in and get it.
-
She scans it and
she puts it in the bucket.
-
And all of the rest of the technology
is kind of behind the scenes.
-
So she gets to now focus on the
picking and packing portion of her job.
-
Never has any idle time,
never has to leave her matt.
-
And actually we think
not only a more productive
-
and more accurate
way to fill orders.
-
We think it is a more
fulfilling way to fill orders.
-
The reason we can say
that though is that workers
-
in a lot of these
buildings now compete
-
for the privilege of working
in the KIVA zone that day.
-
And sometimes we'll catch
them on testimonial videos
-
saying such things as,
-
they have more energy after the
day to play with their grandchildren,
-
or in one case a guy said, "the
KIVA zone is so stress-free
-
that I've actually stopped taking
my blood pressure medication."
-
(Laughter)
-
That was at a pharmaceutical distributor.
So they told us not to use that video.
-
(Laughter)
-
So what I wanted to leave you
with today is the notion that
-
when you let things start
to kind of think and walk
-
and talk on their own, interesting
processes and productivities can emerge.
-
And now I think next time
you go to your front step
-
and pick up that box that
you just ordered online,
-
you break it open and
the goo is in there,
-
you'll have some wonderment
as to whether a robot
-
assisted in the picking
and packing of that order.
-
Thank you
-
(Applause)
