Okay,
we're
live!
So
let
me
just
kick
this
off:
okay,
so
a
very

afternoon
to
everyone
joining
us.
It
seems
like
from
around
the
world
and
we've
got
people
from
Nigeria
people
from
Texas
people
from
Brisbane
and
people
from
around
around
Asia
Pacific
so
good
morning,
good
afternoon
good
evening.
A
Everyone
and
welcome
to
this
event:
I'm
Julian
Gordon
I'm,
the
VP
Asia
Pacific
for
hyper
later
foundation
and
I'm
delighted
to
be
here
to
host
this
virtual
Macau
meet
up
the
first
Meetup
we've
had
in
a
Macau
for
a
while.
So
this
is
great.
We're
live
on.
Youtube
I
had
a
pleasure
of
meeting
our
presenter
here
at
dalibur
Von
chasky,
who
in
last
month
in
Hong
Kong.
A
So
we
had
a
really
interesting
discussion
about
his
PhD,
where
he's
building
a
cmms
system,
which
is
a
computerized
maintenance
management
system
using
hyperledger
Fabric
and
it's
great,
and
it's
really
great
that
he
can
share
it
here
today.
So
we
discussed
doing
that
and
it's
great
that
this
is
this
has
happened.
A
So
dalibur
is
the
operations
and
maintenance
manager
at
Dollar,
Palmyra
Macau,
which
runs
the
sky
cab,
cable
car
system
at
the
famous
wind,
Palace
Resort,
and
he
is
doing
his
PhD
in
information
systems
at
the
University
of
Saint,
Joseph
and
I
will
be
meeting
him.
Actually,
we've
got
another
event
happening
a
un
event
happening
in
Macau,
which
is
a
very
cool.
It's
kind
of
like
a
Macau
week
before
I
hand
over
to
dalibur
I've
got
a
quick
housekeeping
item,
as
this
is
a
Linux
Foundation
Meetup
event.
A
I
have
to
note
that
to
all
participants
they
must
comply
with
our
antitrust
policy,
which
you
can
always

questions
in
the
chat
below
I.
See
that
also
tell
us
where
you're
from
that'll
be
fun
and
I
will
track
the
questions
and
we'll
actually
make
this
a
little
bit
interactive
and
now
I'm
now
going
to
pass
over
to
you
delabour.
So
please
take
it
from
here.
Thank
you
again
for

to
us
today.
B
Yeah,
thank
you
Julian.
Thank
you
for
introduction.
Thank
you.
Everybody!
Everybody
who
attended
this
presentation
good
morning
good
afternoon
good
good
evening,
wherever
you
come
from
yeah
today,
I
will
be
presenting
about
my
my
my
current
research
and
with
some
some
slight
demo
with
how
we
build
the
computerized
maintenance
management
system
with
hyperledger
fabric.
We
will
learn
how
cmms
can
change
operational
services
and
and
operational
Services
of
one
cable
car
companies.
B
In
short,
we
will
have
a
introduction
of
myself
my
my
my
project,
short
abstract,
cmms,
how
it's
defined.
What
does
it
mean
Urban,
cable
car?
Why
we,
why
we
choose
to
do
the
the
Europe,
Urban,
cable,
car,
operational
services
and
business
processes
of
of
that
that
Enterprise,
who
run
the
operational
Services
of
an
encable
car
development
of
the
smart
contracts
in
go
where
I
will
present
my
my
current
status
of
my
my
smart
contracts
or
chain
codes?
B
B
In
the
meantime,
I
was
promoted
senior
operations
and
maintenance
manager
at
Doppler,
Macaulay
mitada
members
of
the
Serbian
Chamber
of
Commerce
Austrian
Chamber
of
Commerce
and
Macau
data,
Lab
Association,
Community
member.
My
current
research
include
blockchain
technology,
Internet
of
Things
industry
4-0
and
data
science.
In
short,
we
will
move
now
to
to
just
briefly
explain
you.
B
Let's
define
cmms
literature,
it's
it's
very
fruity.
There
is
a
lot
of
a
lot
of
different
definitions
and
whatever
you
use
would
be
fine.
I
personally,
like
like
this
one
as
cmms,
it's
defined
as
a
software
application
designed
to
assist
in
planning
and
managing
maintenance
operations,
Enterprise
Asset
Management,
their
intelligence
utilization,
tracking,
the
work
records,
effective
maintenance
in
in
various
various
really
various
Industries.
B
B
You
I'm,
quite
sure
you
you
already
have
this.
You
experience
this
everything
goes
on
a
on
a
smart
devices,
utilizing
the
the
faster
internet
speeds
and
and
higher
requirements
to
support
further
iot
devices
and
artificial
intelligence.
This
is
current,
and
this
is
where,
where
cmms?
Actually
it's
it's
its
heading,
demystifying
maintenance
with
the
cmms,
although
the
the
level
of
of
today's
development
of
of
of
digital
technology
and
all
other
Technologies
available
to
all
of
us,
cmms
still
facing
issues,
management,
assisting
software
tool
called
cmms.
B
How
I
like
really
to
call
it
still
struggle
to
overreach
over
Arch
the
needs
on
on
complete
and
and
complete
Synergy
of
of
business
processes
of
an
an
Enterprise
organizations
failed
to
to
harness
that
all
the
benefits
cmms
could
bring
and
and
I
found
in
a
literature,
and
that
that
the
the
failing
rate
it's
it's
really
shocking,
it's
90
and
usually,
when
you
talk
to
the
people,
they
will
always
say:
oh
yeah,
you
know,
but
my
previous
system
was
better.
Previous
system
was
better.
B
You
know
somehow
tmms
it's
falling
into
its
with
its
implementations.
Solutions
need
more
integration
with
a
relative
organizational
factors
like
asset
allocation
decision
making
structures,
Senior
Management
support,
which
is
very,
very
important.
Employee
involvement,
cmms
are
falling
because
employees
are
are
most
of,
the
cases
are
not
trained,
practical
instructions
are,
are,
are
not
there,
and
all
this
lead
should
shall
lead
actually
to
effectiveness
of
total
predictive,
productive,
productive
maintenance
overall
and
predominantly
still
as
of
today.
B
Cmms
is
just
is
used
as
a
reactive
tool
that
that
should
not
happen.
Where
are
the
solutions?
Sophisticated
cmms
application
must
improve
maintenance
operations,
reduce
costly
down
times
and
increase
acid
utilization,
and
reliability
and
I
would
say,
mass
mass
enhance
planning
and,
and
we
are
moving
toward
the
predictive
predictive
maintenance
cmms
system,
as
it
seems
by
me
and
and
my
my
research
team
has
to
be
built
on
a
base
on
for
for
paradigms:
blockchain
iot,
industry,
4-0
and
smart
maintenance.
B
When
we
talk
about
the
maintenance
you
know
and
and
maintenance
maintenance
operation
or
actually
operational
Services,
it's
gather
big
big
amount
of
data
and,
and
this
collected
maintenance
data
becoming
a
primarily
structured
information.
Now,
if
we
put
big
data
analytics
and
deep
learning
to
identify
the
problems,
improve
maintenance
processes,
reduce
knowledge
gaps
consequently
will
increase
our
costs,
Effectiveness
and
the
uptime,
and
at
the
end,
if
we
have
this
integrated
software
solution,
it
will
help
cable
cars.
B
You
know
companies
to
to
manage
their
product
life
cycle
and
increase
the
value
of
their
assets.
Once
once
you
properly
use
the
cmms,
you
know
for
sure
you
you
we
will.
We
will
get
it.
Elevated
cost,
effective
experience
where
computers
and
maintenance
software
can
store
data
and
make
cost-effective
maintenance
decisions
which
will
support
the
management
better
sharing
between
the
organizations
organization
can
can
use
this
integral
method
management
system,
which
should
share
improvements
between
the
the
different
sites,
maintenance,
safety,
very
important
part
of
of
Maintenance.
We
are
all
aware
of
this.
B
B
At
the
very
end,
yeah
I
I,
like
the
the
this,
is
one
sentence
from
the
from
the
book
digital
disciplines
where,
where
now
digital
Solutions,
when
we
talk
about
cmms,
obviously
it's
it's
a
digital
solution.
Digital
Solutions
should
be
informative,
driven
and
incorporate
Mobility
connectivity
and
visualization
to
create
new
business
value.
B
That's
the
primary
job,
primarily
job
of
the
cmms,
to
create
the
business
business
value.
Now,
if
we
talk
about
my
projects,
why
I
choose
the
urban
Cable
Car?
Naturally
I'm
15
years
in
in
in
in
this
in
this
industry
and
I,
see
that
industry
it's
lacking
off
of
one
cmms,
who
will
Who
will
really
overarch
all
the
businesses
processes
a
little
bit
later,
I
will
talk
which
Which
business
processes
are
important
and
which
business
processes
are
are
actually
put
in
in
place
to
work
just
a
little
bit
short.
B
Why
Urban
cable
cars,
the
next
generation
of
public
public
transport
technologies
that
will
transfer
urban
life
significantly
from
the
stand
of
public
transport,
the
cable
cars
technology
they're
dealing
with
a
massive
demand
of
safe
and
reliable
level
transport
operations?
At
the
same
time,
that
means
that
new
emerging
digital
technology
with
has
to
deal
with
the
enormous
amount
of
data
data
which
has
are
produced
by
by
daily
operations.
This
data
must
be
analyzed,
calculated
and
compiled
in
this
new
digital
Technologies.
B
Why?
Why
why
everybody
will
say
yeah
why
why
cable
cars
are
are
are
are
important
to
you
know.
The
awareness
of
cable
cars
should
be
more
elevated
should
be
yeah.
We
should
more
talk
about
the
cable
cars
because
it
brings
benefits
to
for
the
community
cable
cars
offer
a
new
level
of
urban
transport.
Where
can
be
easily
integrated
into
already
existing
system
fill
the
gaps
offer
trip
times.
A
huge
capacity,
of
course
cannot.
B
Reach
cannot
match
the
the
capacity
of
of
of
a
Metro,
but
some
some
other
Solutions
are
are
very,
very
visible,
feasible
with,
with
with
the
cable
cars,
three
important
tenants,
Mobility
for
all
cable
cars,
affordable
and
barrier-free.
Urban
integration,
as
I
mentioned,
seems
to
be
easy.
Integrated
into
existing
transport.
Next
Network
can
extend,
can
go
over,
let's
say
a
geographical
obstacles
and
the
most
important
is
really
environmental,
friendly,
ropeway
system,
zero,
zero,
zero,
local
emission
of
the
CO2-
and
here
it's
one
very
nice
graph.
B
When
when
we
can
see
how
what
how
the
the
actually
which
are
the
functions
performed
by
the
cable
cars
you
can
connect,
you
can
create
mini
transport
networks.
You
can
bridge.
This
is
the
river
you
can
go
over
the
over
the
river
extend
the
the
lines.
Relief
streets
are
mostly
most
of
the
time,
blocked
by
The
Cars
and
and
that's
where
the
cable
cars
technology
steps
in
we
we
in
Doppler,
we
have
a
new
paradigm.
B
B
Operational
Services,
it's
referring
to
day-to-day
activities,
business
processes
referring
to
the
long-term
or
or
business
strategies,
and
all
of
these
shall
be
presented
and
shall
be
interpreted
into
the
next
next
graph,
where
we,
where,
where
I,
where
I
I
I
presenting
the
the
business
processes
of
an
and
cable
car
Enterprise,
where
we
have
a
human
resources,
business
operations,
business
processes,
operational
business
processes,
maintenance,
proficiency,
Safety,
Management
and
financial
business
processes.
These
business
processes
are
essential
for
an
Enterprise
for
various
reasons.
B
Right
when,
first,
when,
whenever
we
come
to
a
new
company-
or
you
know,
we
are
employee,
we
first,
we
Face
human
resources,
and
now
we
can
see
that
human
resources
providing
the
information
to
the
operational
business
processes,
human
resources,
of
course,
supplying
data
to
the
maintenance.
And
if
we
look
now
the
maintenance,
it's
just
collecting
the
data
from
the
proficiency
right
when,
when
somebody
comes
to
the
company
needs
to
be
trained
and
only
trained
people
can
do
the
maintenance
same
as
the
train
people
can
do.
B
The
the
the
the
operations
same
is
the
Safety
Management
business
processes,
which
are
really
indirect,
direct
link
with
the
business
maintenance
processes
and
at
the
end,
of
course,
we
all
do
this
for
a
money.
There
is
a
financial
business
processes
where,
where
where
the
company
has
to
yeah
issue
the
invoice
purchases
of
the
spare
parts,
etc,
etc.
B
B
And
we
talk
when
we
say
the
smart
contracts,
yeah
Nick
zabbo
for
me
still
the
best
definition
of
the
smart
contracts,
computerized
transaction
protocol
that
executes
the
terms
of
the
contracts.
Yeah
smart
contracts
is
nothing
he's
just
nothing
else
than
dealing
with
it's
invoked
by
other
functions
and
storing
and
updating
The
Ledger
before
I
move
to
to
to
hyperledger
and
and
and
my
my
my
my
deeply
explanation
of
my
project,
four
tenants
of
the
blockchain.
Of
course,
smart
concert,
it's
one
of
them.
What
are
the
advantages?
B
B
In
short,
hyperledger
fabric,
you
tend
to
be
extended
as
a
foundation
for
developing
application
solution
with
modular
architecture,
allows
yeah
components
such
as
consensus
and
memberships,
Services,
modular
and
versatile
design
permission
architecture.
That
was
very
important
for
my
project
that
it's
I'm
personally
I
think
that
that's
the
right
approach,
because
it's
Enterprise
you're
dealing
with
a
huge
amount
of
data
and
making
it
permissioned
make
our
life
easier,
open,
Smart,
contract,
crude
definition.
B
B
B
I
I
use,
hyperledger
Firefly
with
my
iot
works,
really
fast
was
really
reliable
and
some
some
initial
test
proof
the
the
concept
it
it's
the
it's
it's
a
system
of
records
for
any
digital
digital
asset.
It
enables
developers
to
build
blockchains
application
for
Enterprise
and
really
radically
faster.
B
B
My
my
network,
my
my
blockchain
network,
it's
it's
created
on
a
on
a
blockchain
business
Cloud
provided
by
collido,
it's
very,
very,
very
easy,
very,
very
approachable
user
experience.
I
might
say
this
is
basic.
Where
I
create
you
can
see
here,
Ops
and
Mt.
It's
Ops
referring
to
operational
business
processes.
B
This
is
the
maintenance
business
processes
with
two
peers
where
maintenance
contract
is
created,
sent
to
the
peers,
sent
back
for
endorse
and
send
back
then
send
to
the
ordering
Services
ordering,
certainly
putting
back
it's
updating
the
The
Ledger
the
world
State
and
The
Ledger.
Then
we
have
information
that
that
transaction
transaction.
It's
it's
done.
The
second
part.
It's
also
hyperledger
Firefly.
B
In
this
case,
my
my
hyperledger
Firefly,
which
or
it's
run
locally
really
stores
all
the
data
from
the
sensors.
How
how
my
my
smart
contracts
are
organized
and
how
how
how
would
they
were
develop?
This
is
currently
list
of
my
smart
contracts.
Yeah.
It's
a
function,
but
I
keep
this
just
because
of
the
name.
Actually,
there
are
two
more
but
just
because
of
the
space
I
I
put
yeah
employee,
smart
contracts,
which
obviously
deals
with
HR
essential
HR.
B
We
have
a
daily
operational
log,
smart
contracts,
which
deals
with
daily
operational
logs,
update
downtime
events,
contract
yeah.
We
we
don't
love
downtime,
but
our
solution
has
to
has
to
deal
with
has
to
deal
with
the
down
times
in
the
best
proper
way
operational
down
times
technical
down
times
passenger
related
down
times
and
and
all
this
information
shall
be
stored
properly
on
shop
stores
properly
on
The
Ledger.
B
I
have
developed
one
smart
contracts,
it's
called
iot
smart
contracts,
which
is
installed
on
a
firefly
who
is
dealing
with
with
information
from
the
sensors
storing
the
sensor,
potentially
the
the
the
the
Firefly
super
node
shall
communicate
with
with
the
collido
blockchain
network
and
and
updating
and-
and
you
know
you
have
to
if
you
have
a
sensor,
detecting
the
the
the
breakdown
operator
show
Define.
Is
it
corrective
or
it's
failure
or
yeah?
B
The
repository
I
used
repositories,
I've
used,
of
course,
fabric
chain,
cargo
contract,
API
and
and
less
the
sheen
package,
but
the
public
samples,
of
course,
Firefly
I
also
must
mention
mini
fabric,
it's
called
mini
fabric,
but
there
is
nothing
mini.
There's
that's
great
tool,
working
really
supporting
100
of
the
of
the
of
the
function.
I
need
for
testing.
B
My
smart
contracts
here
is
one
simple
example:
several
function
I
listed
from
my
my
smart
contracts,
the
structure
of
my
daily
Operation
Log,
smart
contracts,
the
structure,
yeah
structure,
yes,
I
mentioned
on
the
beginning,
but
I
have
to
mention
it
again.
I
choose
golang
because
they
are
simply
availability
of
the
of
the
of
the
literature
and
documentation.
It's
it's
well
organized
it's
easy
to
use,
especially
for
me
who
is
not
coming
from
the
computer
science
with
computer
science
background
the
function
defined
I
are
several
I
put
this
this.
B
Typically,
this
smart
contract
has
more
than
12
functions,
but,
let's
say
create
new
new
daily
operational
log
read
get
daily
operation
by
range
update
daily
operational
log.
Here
it's
very
important
to
define
the
structure,
the
data
item.
We
we
we
will
use
like
a
daily
number
of
passengers
who
is
on
the
shift
early
shift,
late
shift
in
cable
cars
has
a
usually
most
of
the
time
they
have
a
two
stations
Drive
station
return
station,
who
is
who,
where
it's
going?
B
You
know
daily
daily
updates
weather
condition,
also
querying
daily
operational
log
by
by
who,
by
by
the
by
the
down
times
they
also
what
what
I
massively
massively
use
and
what
I
was
really
happy
to
to
achieve.
It
was
calling
cross-chain
codes
function
where,
from
one
daily
operational
log,
I
managed
to
create
corrective
maintenance
work
order,
I
can
create
down
times,
etc,
etc
and,
of
course,
very,
very
get
yeah
very
easy
to
to
to
get
query
results.
B
B
I
need
just
to
put
everything
in
in
working.
Here
is
the
yeah,
as
I
said:
I
use
micro,
Raspberry,
Pi,
Pico
and
micro
python
to
create
one
application
to
create
one
one,
small
software
which
is
uploaded
on
a
on
a
Pico,
and
this
Pico
will
generate
Json
format
file,
and
we
can
see
that
now.
It's
already
I
will
run
simply,
and
we
can
see
now
should
be
test
hello
world.
This
is
code
which
which
just
simply
testing
yeah.
B
Now,
if
we
go
back
to
to
my
yeah
I
use
certificates,
its
connection
is
secured,
which,
via
the
mqtt
broker
waiting
for
the
event,
I
will
now
press
the
button
very
simply
press
the
stop
button
which
will
mimicking
the
the
sensor
and
yeah.
Now
you
can
see
that
that
the
Json
file
it's
it's
generated.
This
is
just
printed
with
ID,
19,
19e
and
I
will
just
go
back
here
and
see
yeah.
B
You
can
see
now
on
our
web
broker
web
broker,
our
our
stop,
stop
button
is
recorded,
and
when
we
use
the
the
Firefly,
we
can
see
that
yeah.
Now
the
the
succeeded,
transfer,
it's
cons,
succeeded
it's
here
and
it's
store
and
you
can
see
that
it's
matching
here,
just
for
the
sake
of
of
Saving
Times
I
put
here,
the
the
I
just
added
five
minutes
to
the
I,
just
added
five
minutes
for
the
downtime,
but
you
can
see
that
the
entire
information
of
that
stoppage.
B
Its
store
has
is
description,
emergency
stop
button,
usually
events
and
referring
to
the
to
the
events
when
the
the
actually
the
stop
button.
It's
it's
reset
when
this
is
the
ID.
This
is
the
event
when
the
event
starts,
which
is
pretty
much
match
with
which
my
time
and
events
type
its
emergency,
stop.
B
Whoever
Works
in
a
in
a
with
a
firefly,
it's
very,
very
straightforward,
very
easy
to
use.
There
is
a
very
nice
documentation
and
how
to
deploy
the
smart
contracts.
We
can
see
that
that
here
now
we
can
see
that
when
you,
when
you
define
your
your
smart
contract
interfaces
and
instances
it's
generating
the
Swagger
in
a
Swagger
I
can
yeah
just
simply
post
query,
get
all
the
events,
and
my
my
my
let's
say:
emergency
stop.
19
e
should
be
now
stored
and
recorded.
B
B
Where
now,
when
I,
as
I
said,
you
know,
we
will
have
a
big
data
of
of
big
stoppages,
big
amount
of
stoppages-
it's
not
only.
This
is
just
a
stop
button.
You
will
have
a
switches,
sensors,
etc,
etc,
and
all
this
has
to
be
analyzed
and
and
and
and
and
big
data
analytics
are
coming,
and
that's
where
my
my
project
is
heading
I
will
need
deep,
deep,
deep
learning
approach
to
find
a
you
know
if
some
faults
are
repeatable,
why
they're,
repeatable,
etc,
etc.
B
Another
another
part
of
it's,
my
my
collider
platform,
really
really
easy
to
use
and
I'm
really
enjoying
using
it.
Give
me
give
me
really
this
sense
of
power
that
I
could
I
can
develop
a
smart
contracts,
as
I
said:
I'm,
not
computer
science,
but
my
my
my
my
my
love
with
coding
yeah,
it's
fully
fully
utilized.
What
is
great,
with
this
platform,
we
have
a
rest
API
Gateway,
which
can
be
which
can
be
used
to
really
communicate.
B
B
Yeah
a
little
typo
but
should
be
okay.
Yeah
we
can
see
transaction
went
through
signer,
it's
a
maintenance
technician.
We
can
again
easily
query
this
we
can
see.
Now,
where
is
our?
Where
is
our?
How
how
this
daily
operational
logs
log,
it's
it's
actually
stored,
read
daily
operational
log,
we
say
888,
we
say.
B
Yeah
here
it
is
and
yeah.
Of
course,
this
is
now
a
pre
pre-recorded
data
and
you
can
see
you
can
store
whatever
you
need
for
your
for
your
application
owner.
It's
creator
of
the
daily
operational
log
yeah
could
be
here:
assigner,
operational,
operational
hours,
number
of
passengers,
number
of
carriers,
carriers
or
cabins,
etc,
etc.
One
thing
which
is
very,
very
interesting
for
me
very
important,
I
I,
really
like
it.
B
Maintenance
technicians,
you
see
that
the
chain
codes
I'm
using
calling
the
the
other
chain
codes.
It's
I'm,
using
calling
using
the
chain
codes,
Ops
operations
on
default,
channel
yep.
Let's
use
zero,
zero,
zero,
eight
eight
to
eight,
let's
see
lucky
number,
and
now
we
have
it
valid
and
stored
on
on
a
ledger
that
the
speed
is
just
amazing
again.
B
We
can
simply
query
now
this,
but
we
will
query
with
our
downtime
event
or
downtime
events:
smart
contract
right,
we
use
operational,
smart
contracts
to
create
downtime
event,
but
now,
with
these
downtime
events,
we
will
with
the
downtime
event,
we
will
see
if
this
is
really
existing
yeah
user
test.
3
is
my
my
really
lucky
user.
B
I
really
like
to
use
it,
but
yeah
now
we
are
using
chenco
downtime
event
yeah,
where
I'm,
where
I'm
querying
get
the
status
of
the
downtime
event,
condition
condition
zero.
Referring
to
that
that
downtime,
it's
not
it's,
not
validated.
It's
not
completed
another
cross
cross
chain
code
call
could
be
also
calling
corrective
maintenance.
You
know
during
the
during
the
daily
operations,
sometimes
we
experiencing
the
finding
some
errors,
some
some
some
system
yeah.
That
system
needs
some.
B
Some
some
corrective
actions
here
I
will
now
call
the
transaction
calling
cross
change
corrective
maintenance
task
very
simple
again
from
operation
smart
contracts,
I
will
call
maintenance,
smart
contracts,
calling
cross
chain
code.
Yeah
I
will
put
here
today.
It's
22nd
and
yep
again
message
message:
the
blockage
form
went
through
it's
already
on
The
Ledger.
Now
we
can
simply
now,
even
with
with
the
fire
with
with
a
rest
API.
We
can
query
to
see.
Where
is
our
Ops?
B
B
B
B
B
B
B
B
Just
some
closing
thoughts
with
after
this
presentation,
Where
We,
Are,
yeah
conclusions
and
Future
Works
I
will
get
back
again
to
to
my
really
favorite
book
digital
disciplines.
We
see
how
datas
are
created
and
how
data
has
to
be
used
in
his
book
weinman
and
verse,
Neymar
defined
for
digital
disciplines.
Operational
excellence
must
now
be
complemented
by
information
Excellence.
We
see
that
now
solution.
We
we
have
this
digital
transformation,
which
must
extend
product
leadership
to
solution
leadership.
B
Not
only
you
know
providing
the
the
manufacturing,
the
cable
cars
yeah.
We
can
provide
the
entire
solution
with
data
analysis
of
of
one
operational
site,
customer
intimacy,
it's
evolving
into
Collective,
intimacy
and
now
what
we
are
getting
is
a
final
result.
It's
traditional
Innovation!
It's
no
longer
enough.
We
will
have
accelerated
information
with
all
these
fire
hose,
like
stream
of
data.
B
Your
push
to
to
to
to
the
new
new
Innovations
and
really
my
closing
thoughts
on
on
this
on
on
my
project
is
that
we
we
Define
here
I
found
very
nice:
smart
maintenance
definition.
We
Define
an
interpret
smart
defense,
some
smart
maintenance
with
four
underlying
Dimension
data-driven
decision
making
human
capital
resource
and
internal
and
external
integration.
Through
my
demo
and
all
my
my
samples
you,
you
can
see
that
all
datas
are
there,
data
has
to
be
used,
people
has
to
be
involved.
A
A
A
A
C
Yeah,
so
I'll
just
go
over
them
by
the
way
question
two
I
think
you
partially
answered
for
me
and
I've
got
to
follow
on
to
it
further
down
in
the
chat.
But
the
first
question
is
really
in
you:
the
use
of
a
cmms
or
Erp
or
eam
or
whatever
you
want
to
call
it
when
you're
using
it
for
condition
based
asset
maintenance
strategies,
so
more
that
predictive
maintenance
moving
into
prescriptive
maintenance.
C
Where
do
you
see
the
use
of
a
blockchain
and
smart
contracts
or
chain
code
in
dealing
with
the
data,
be
it
streaming
data
or
even
bulk
data
that
comes
in,
for
example,
an
oil
sample
that
comes
in
every
month?
How
do
you
see
that
fit
into
you
know
this
sort
of
architecture
of
the
use
of
a
of
a
blockchain
yeah
I
can
talk
about
the
other
questions
after
that,
if
you
like.
B
B
B
This
data
must
be
now
compiled
extracted
and
we
we
see
what
these
datas
are
telling
us,
as
I
presented
with
I,
founded
that
the
hyperledger
Firefly,
for
example,
is
doing
great
job
I,
simply
coded
my
my
picot
to
to
send
Json
file,
and
once
you
get
the
Json
file
store
it
on
on
a
ledger
yeah,
you
can
extract
it
all
all
these
files,
all
these
datas
and
and
with
some
Advanced
deep
learning
yeah.
You
can
also
you
you
you.
B
You
mentioned
oil
samples
in
in
in
our
in
in
cable
car
industry,
for
example,
we
are
taking
the
oil
samples
every
every
1000
operating
hours,
which
comes
like
half
yearly,
for
example,
just
just
a
gearbox
oil
samples
yeah.
This
could
be
also
edited.
Could
be
ways
right:
we
we
can
enter
this
data
because
I'm,
usually
I,
don't
do
my
oil
analysis
in
in
my
company.
We
are
sending
this
to
to
our
our
vendors
but
yeah
that
that's
that's
that's
great
question.
Yeah!
B
C
And
so
the
follow-on
from
that,
which
is
the
question
to
part
two
of
question
two
is
really
about
now.
You've
got
that
data,
be
it
transactional
or
maybe
it's
a
change
out
of
a
component
in
a
piece
of
equipment
that
sort
of
thing
that
gets
recorded
on
the
blockchain,
the
I
guess.
My
question
is:
do
you
see
that's
the
thing
to
use
to
establish
Providence
of
the
data
that
relates
to
that
piece
of
equipment,
for
example
selling
it
on
a
list
on
a
second-hand
Market
with
equipment?
C
Because
not
all
equipment
gets
kept,
it
sometimes
it
gets
it
gets
sold
because
there
are
changes
and
purpose,
oh
yeah,
but
definitely
from
a
mining
perspective
which
is
where
I'm
coming
from.
But
you
know
that's
one
of
the
things
I
thought
that
would
be
appropriate
with
the
blockchain
was
the
use
of
storing
the
data
to
show
that
you
have
an
immutable
record
of.
B
B
Yeah,
that's
very
good
question.
I!
Must
it's
not
the
phrase?
But
it's
really
good
question
just
to
explain
you
as
I'm,
coming
from
the
cable
car
industry
and
in
a
cable
car
industry,
I'm
working
for
the
doppelmeyer
and
I'm
I'm
I
have
a
direct
direct
purchasing
link
with
the
dopamine
customer
support
and
you
know
like
100.
B
We
are
installing
only
original
spare
parts
from
our
manufacturer,
but
yeah
good
question
that
that
the
spare
parts
were
coming
because
I
created
one
smart
contract
which
is
dealing
with
assets
where
I,
where
I
put
the
the
origin
of
of
of
supplier
and
that
could
be
really
could
be
really
in
in
more
details.
That's
very
good,
very
good
suggestions,
because
I
have
to
pay
attention
because
yeah
naturally
I'm
buying
spare
part
just
from
one
by
and
also
my
contractual
obligation
with
with
with
my
client.
B
It's
that
we
always
buy
original
spare
parts
yeah,
but
a
very
good
question
yeah,
maybe
I
should
I
will
definitely
adapt.
My
my
adjust
my
my
my
my
smart
contract
for
for
assets
that
that
the
provenance
is
that
yeah
that
we
cannot
use.
But
again
you
know
that
that's
where
the
the
blockchain,
actually
it's
a
little
bit
falling
apart.
I
must
say
this
scalability.
You
know,
because
I
can't
do
that.
B
You
know
without
my
my
my
my
counterpart,
where,
where
the
blockchain
there
were
the
spare
parts
are
coming
right.
They
have
to
put
this.
They
have
to
put
this.
You
know
the
format
of
data
and
yeah.
It's
it's
quite
interesting,
yeah
very,
very
interesting.
Thank
you,
Mark
that
that's
very
good
question.
I
will
really
work
on
it.
C
I'll
just
follow
the
third
one,
I
think
it
also
relates,
and
maybe
there's
an
answer
for
Muhammad
as
well,
about
attaching
a
SQL
database
to
fabric
for
backup
along
those
same
lines.
Is
that
sort
of
what
you
would
need
to
do
to
pull
data
for
use
in,
say
a
data
Lake
to
mine
to
do
things
like
prescriptive,
maintaining
sections
or.
B
What
what
I
presented?
It's
a
it's
really
exactly.
As
you
said,
it's
it's
a
blockchain
infrastructure
based
on
a
hyperledger
fabric
protocol.
You
you
see
that
I'm
not
avoiding,
but
there
there
is
no
application.
That
should
be
decentralized
app.
Who
will
Who
will
access
this
this?
You
know
that
you
know
that
smart
contracts
create
this
world
State
and
create
immutable
records.
Yes,
there
should
be.
B
A
B
A
B
A
A
Is
it
the
data
hard
to
find
or
don't
they
see
the
value
of
using
it?
So
what
if
you
look
at
the
question
so
which
department
and
it
is,
is
and
with
the
hardest
to
put
it
on
CMS
their
partner?
Is
it
because
they
find
it
hard
to
find
the
data
or
basically
they
may
not
see
the
value?
The
conceptual
question:
why
do
you
think
the
challenges
will
be.
B
The
biggest
challenge,
the
biggest
challenge,
is
actually
the
Senior
Management.
Usually
you
know
when,
when
you're
employing
the
blockchain
and
and
even
even
this
solution,
if
thanks
God
once
would
be
implemented,
you
will
not
know
that
it's
a
blockchain
right.
You
will
have
a
front
front-end
application
and
you
know
where
I
see
the
struggle.
It's
that
the
top
management
you
know
has
to
has
to
be
tackled.
B
They
have
to
be
aware
of
the
advantages
and
once
when,
when
when
they,
when
they,
when
they
accept
the
solution,
then
then
would
be,
would
be
easy,
actually
Terrence
very
good
question.
But
you
know
once
you
you
start
using
you.
You
should
not
notice
the
difference,
because
you
will
have
a
you,
will
have
a
front
front-end
application
and
and
all
what
it's,
what
I
show
it
will
be
happen.
Yeah
under
the
hood
I,
don't
expect
yeah.
B
Actually,
all
these
departments
I
don't
expect,
let's
say
any
resistance
once
if
it's
approved
by
the
serial
management,
if
they
are
aware
of
of
how
data
would
be
managed
and
that
you
will
have
a
because
even
yeah
on
my
previous
sites,
I
always
was
struggling.
Oh,
what
yeah,
because
they
will
say
yeah,
you
know
we
had
this
fault
before,
but
how
it
happens.
Where
it
happens,
you
know,
datars
are
lost
when
once
you
have
a
I
have
a
blockchain
and
you
have
a
immutable
Ledger
and
you
will.
A
Yes,
I
think
what
Terence
is
they
just
put
a
comment?
He
said
he's
got
bad
earlier.
He
said
once
you
get
obviously
like
all
these
things.
You've
got
to
get
commitment
for
management.
You
can
do
that.
You
speed
it
up.
It's
a
strong
value,
proposition
I
think
which
we
discussed
right,
but
yeah.
It's
it's
always
difficult
to
get
there,
but
once
you've
got
it,
everything
comes
into
line,
hopefully
yeah,
all
right,
so
I
think
I
would
come
to.
A
A
Thank
you
for
for
that
presentation,
and
everyone

YouTube

insightful

Thank

the
question
really

how
is
that?
How
would
anyone
get
in
contact
with
you
is?
It
is
oh.
B
Oh
yeah,
LinkedIn
yeah
LinkedIn,
please
anything
about
what
what
I
presented
please
just
let
me
know:
I
cannot
share
still
the
smart
contracts.
I
have
my
repository,
which
is
really
under
heavy
development,
and
it's
not
yet
ready
for
for
to
to
be
probably
published,
but
yeah
I'm
really
happy
to
talk
and
I'm
really
happy
to
to
to
listen
to
any
any
suggestions.
Any
any
any
proposal.
Yeah
Mark
was
great
Terence
as
well.
B
Thanks
for
all
the
all
the
questions
and
yeah
I
see
here,
one
more
question
for
from
Wong
may
know
if
you
need
to
take
care
of
yeah
date
time
related
events,
as
I
mentioned,
you
can
easily
work
with
the
timestamps
in
hyperledger.
You
can
create
preventive
tasks
and
again
you
need
a
good
dap
development
developer.
Who
will
Who
will
manage
the
because
yeah,
even
you
can
create
preventive
maintenance
tasks
and
it's
on
a
ledger
and
once
you
it's
triggered
by
time
or
working
hours,
you
will
just
update
the
state.
B
A
Okay,
excellent.
Thank
you.
Thank
you.
Thank
you.
Everybody.
Thank
you,
yeah.
You
can
also
connect
with
me
on
LinkedIn.
You
can
connect
within
within
the
community
on
the
Meetup
yeah.

continue
this
conversation
once
again.

Dad.
