Introduction
ou
'
re
looking
to
cut
manufacturing
downtime
and
costs
without
betting
your
operation
on
vague
experiments
.
If
you
'
ve
already
tried
spreadsheets
,
alerts
,
or
one
-
off
automation
,
you
know
the
hard
part
isn
'
t
wanting
better
results
it
'
s
turning
data
into
decisions
on
a
repeatable
schedule
.
This
book
gives
you
a
clear
,
step
-
by
-
step
way
to
apply
AI
where
it
matters
most
,
from
seeing
problems
before
they
stop
production
to
planning
work
and
energy
with
confidence
.
You
'
ll
walk
through
the
practical
playbook
behind
AI
In
Manufacturing
Playbook
:
predictive
maintenance
,
defect
detection
with
computer
vision
,
demand
-
aware
supply
forecasting
,
constraint
-
based
scheduling
,
and
energy
cost
reduction
.
WHAT YOU'LL BUILD
Five
connected
capabilities
:
a
failure
forecast
that
turns
sensor
data
into
repair
plans
,
a
defect
triage
loop
that
stops
scrap
before
it
spreads
,
a
supply
model
that
fuses
demand
with
supplier
risk
,
a
constraint
-
aware
scheduler
that
protects
throughput
,
and
an
energy
forecast
that
targets
peak
demand
before
it
gets
expensive
.
I
PA RT 1 : R E D U C I N G U N P L A N N E D D O W N T I M E
Predictive Maintenance for
Downtime
f
you
only
react
after
a
machine
stops
,
you
accept
the
worst
timing
:
you
fix
damage
after
it
grows
,
you
hunt
for
parts
when
lead
times
hurt
,
and
you
reshuffle
work
because
production
already
slipped
.
Your
equipment
usually
gives
clues
earlier
vibration
shifts
,
heat
changes
,
motor
current
drift
,
oil
quality
decay
,
cycle
irregularity
,
and
repeated
micro
-
stops
.
The
question
is
whether
you
turn
those
clues
into
a
repair
plan
before
the
stop
happens
.
This
chapter
delivers
a
hands
-
on
approach
to
forecasting
breakdowns
using
sensor
data
and
failure
patterns
,
then
scheduling
repairs
with
confidence
,
using
the
3-
Layer
Failure
Forecast
.
The 3-Layer Failure Forecast: Signals
Patterns
Actions
Your
AI
system
should
not
start
with
a
prediction
label
like
"
will
fail
."
It
should
start
with
the
smallest
truth
you
can
measure
reliably
.
Layer
1
Signals
.
Collect
raw
or
near
-
raw
readings
that
reflect
the
machine
'
s
condition
:
vibration
amplitude
,
bearing
temperature
,
motor
current
,
hydraulic
pressure
,
oil
contamination
.
You
don
'
t
need
every
signal
you
need
the
ones
your
equipment
actually
changes
as
it
approaches
failure
.
Layer
2
Patterns
.
Convert
signals
into
failure
-
related
behavior
:
trends
,
repeatable
signatures
,
or
"
shape
changes
"
that
show
up
before
breakdown
.
Instead
of
asking
"
what
'
s
wrong
right
now
,"
ask
"
how
does
this
machine
behave
as
it
moves
toward
failure
?"
"Your machine didn't fail randomly so why do you treat it like it did?"
Layer
3
Actions
.
Translate
the
pattern
into
a
maintenance
decision
inspect
,
replace
,
schedule
shutdown
,
tighten
alignment
,
change
oil
,
or
monitor
more
frequently
tied
to
a
time
window
and
a
confidence
level
so
technicians
know
what
to
do
and
when
.
Choosing Sensor Inputs That Actually Reflect Failure
Start
with
the
failure
history
you
already
have
.
Look
at
your
last
stoppages
and
write
down
what
each
failure
typically
changes
:
heat
,
load
,
friction
,
lubrication
quality
,
alignment
,
fluid
flow
,
or
mechanical
clearance
.
Then
map
those
changes
to
signals
you
can
measure
.
For
motor
-
driven
machines
,
vibration
and
motor
current
often
reveal
load
changes
and
bearing
issues
.
For
hydraulic
systems
,
pressure
stability
and
flow
behavior
show
internal
wear
.
For
gearboxes
,
temperature
plus
vibration
frequency
content
surfaces
gear
mesh
damage
early
.
Pick
signals
that
meet
three
rules
:
Confirm
you
log
time
consistently
,
capture
enough
samples
during
real
operation
,
and
don
'
t
mix
readings
from
different
operating
modes
without
labeling
them
otherwise
your
patterns
will
learn
"
normal
mode
changes
"
as
if
they
were
failure
.
PRACTICAL TAKEAWAY
Build
your
predictive
maintenance
plan
around
Signals
Patterns
Actions
,
not
around
a
single
prediction
number
you
can
'
t
act
on
.
They
change
before
the
breakdown
not
only
at
the
moment
the
machine
stops
.
They
stay
measurable
across
normal
operations
,
without
constant
drift
or
dropout
.
They
connect
to
a
maintenance
action
,
not
just
"
interesting
data
."
Turning Sensor Data Into Failure Patterns
For
each
known
failure
event
,
pull
the
sensor
history
leading
up
to
it
.
Mark
a
"
before
"
window
(
how
far
back
you
want
to
detect
)
and
a
"
near
"
window
(
how
close
to
failure
you
want
the
strongest
signal
).
Compare
these
against
normal
runs
from
similar
operating
conditions
,
and
test
whether
a
trend
or
signature
strengthens
as
failure
approaches
you
can
start
with
simple
rule
-
based
thresholds
before
training
a
full
model
.
When
you
train
,
keep
it
practical
:
train
per
asset
type
or
machine
family
,
include
operating
mode
context
(
speed
/
load
),
and
validate
on
failures
the
model
hasn
'
t
seen
.
Finally
,
calibrate
the
raw
model
score
into
a
decision
-
friendly
risk
band
that
maps
directly
to
Layer
3
actions
.
Scheduling Repairs From Predictions
Predictions
don
'
t
reduce
downtime
unless
they
change
what
you
schedule
.
Define
a
small
set
of
action
rules
tied
to
risk
levels
and
time
windows
:
FIELD EXAMPLE TANYA, PLANT MAINTENANCE SUPERVISOR
Tanya
managed
a
line
where
a
gearbox
-
driven
unit
often
failed
"
without
warning
."
Technicians
had
been
changing
parts
based
on
hours
,
not
condition
.
By
aligning
sensor
timelines
with
work
orders
,
her
team
found
that
vibration
temperature
and
vibration
energy
drifted
and
spiked
in
the
same
window
before
every
breakdown
.
They
trained
a
failure
pattern
model
for
that
gearbox
class
and
calibrated
the
risk
band
to
trigger
earlier
inspection
while
the
machine
still
ran
reliably
.
The
change
wasn
'
t
the
AI
itself
it
was
tying
machine
behavior
to
the
maintenance
record
precisely
enough
to
learn
the
real
failure
-
approach
pattern
.
Low
risk
continue
run
-
to
-
plan
and
collect
more
data
.
Medium
risk
schedule
inspection
during
the
next
planned
maintenance
window
.
High
risk
plan
a
corrective
repair
at
the
next
feasible
shutdown
and
prepare
parts
.
Critical
risk
request
immediate
intervention
if
safety
or
catastrophic
failure
risk
rises
.
Connect
every
flagged
risk
band
to
a
work
order
with
the
evidence
summary
(
which
signals
and
pattern
features
drove
it
)
and
the
recommended
time
window
and
close
the
loop
by
recording
what
you
found
after
every
repair
,
so
misses
and
near
-
misses
keep
improving
your
labels
.
QUICK ACTION STEP
Pick
one
critical
asset
with
frequent
downtime
.
Collect
24
months
of
sensor
data
plus
work
order
timestamps
.
Match
each
breakdown
to
a
labeled
failure
event
and
pull
the
"
before
"
window
.
Test
whether
signals
repeat
in
failure
-
approach
windows
.
Train
and
calibrate
a
pattern
model
,
set
risk
bands
,
and
create
action
rules
that
open
work
orders
.
After
the
first
planned
repair
,
log
what
you
found
and
update
your
labels
.
CLOSING THOUGHT
Predictive
maintenance
becomes
real
when
actions
get
scheduled
.
When
your
AI
forecast
stops
being
a
dashboard
and
starts
becoming
a
work
-
order
plan
,
downtime
drops
because
you
stopped
guessing
you
learned
what
failure
looks
like
in
your
signals
,
converted
it
into
patterns
your
team
trusts
,
and
scheduled
actions
while
the
machine
still
gave
you
time
.
O
PA R T 2 : C U T T I N G S C R A P A N D R E W O R K
Defect Detection with Computer
Vision
ne
damaged
part
can
trigger
a
chain
reaction
:
the
line
slows
for
inspection
,
workers
rework
,
packaging
gets
reprinted
,
and
the
shipment
slips
.
In
many
mechanical
plants
,
defect
-
driven
rework
and
scrap
quietly
outspend
"
real
downtime
,"
because
defects
show
up
after
the
value
has
already
been
added
during
assembly
,
at
final
inspection
,
or
even
in
the
customer
return
window
.
The
fastest
way
to
cut
that
cost
is
to
stop
treating
defects
like
a
paperwork
problem
and
start
treating
them
like
a
visual
detection
problem
,
using
the
Defect
Triage
Loop
.
The Defect Triage Loop: Detect
Classify
Contain
Detect
.
Your
camera
system
and
lighting
capture
images
from
a
known
position
and
distance
,
and
the
AI
flags
"
something
looks
wrong
"
based
on
visual
patterns
.
Classify
.
Don
'
t
stop
at
"
defect
/
no
defect
."
Label
what
kind
of
defect
it
is
surface
scratch
vs
.
missing
material
vs
.
misalignment
vs
.
wrong
component
because
your
containment
decision
depends
on
the
label
.
FIELD EXAMPLE LUIS, QUALITY MANAGER, PRECISION PARTS
Luis
'
s
real
pain
wasn
'
t
that
defects
happened
it
was
that
they
didn
'
t
show
up
consistently
.
Surface
flaws
and
assembly
defects
popped
up
in
clusters
after
a
tooling
change
or
a
shift
handoff
,
and
his
team
kept
catching
issues
late
,
then
spent
hours
tracing
which
machine
,
batch
,
or
operator
caused
it
.
Computer
vision
became
the
bottom
-
line
lever
:
detect
surface
flaws
and
assembly
defects
automatically
,
classify
them
the
same
way
every
time
,
and
contain
the
problem
before
it
spreads
.
Contain
.
The
system
routes
the
part
to
the
right
path
:
reject
,
rework
,
hold
the
lot
,
or
request
a
quick
human
check
for
borderline
cases
.
Detect: Build a Camera Setup That Finds Flaws Reliably
Computer
vision
fails
most
often
for
a
boring
reason
:
the
image
doesn
'
t
stay
consistent
.
Control
three
things
illumination
,
part
presentation
,
and
camera
angle
.
Lock
the
part
location
with
fixtures
,
keep
the
camera
fixed
,
and
design
lighting
that
highlights
the
defect
instead
of
hiding
it
.
Confirm
steady
brightness
and
sharpness
on
normal
parts
,
then
confirm
defect
pixels
stand
out
repeatably
on
known
-
defective
samples
.
Classify: Label Defects So Quality Can Take Action
Build
a
label
set
based
on
real
actions
,
not
vague
categories
.
For
surface
flaws
,
label
by
defect
type
and
location
.
For
assembly
defects
,
label
by
the
specific
failure
mode
:
missing
component
,
upside
-
down
part
,
offset
feature
,
wrong
orientation
,
or
incomplete
seating
.
Define
each
label
in
simple
,
unambiguous
language
if
two
people
can
look
at
the
same
image
and
disagree
,
your
training
data
will
reflect
that
confusion
.
Luis
tied
each
label
to
a
downstream
decision
:
reworkable
,
scrap
,
or
verify
the
same
paths
his
team
already
used
.
PRACTICAL TAKEAWAY
If
your
images
vary
more
than
your
defects
,
you
'
ll
chase
ghosts
.
Stabilize
light
and
placement
before
you
train
anything
.
Contain: Turn AI Decisions Into Hold, Reject, and Rework Paths
Containment
is
where
computer
vision
starts
cutting
money
.
Build
a
decision
policy
tied
to
classification
output
:
auto
-
reject
high
-
confidence
scrap
-
worthy
defects
,
route
reworkable
defects
to
the
correct
station
,
and
hold
borderline
cases
for
quick
human
verification
.
Add
lot
-
containment
logic
when
a
specific
defect
label
clusters
above
normal
rate
,
pause
and
check
fixture
wear
,
tooling
condition
,
and
the
last
shift
handoff
.
Quality Data Collection That Doesn't Waste Your Team's Time
Start
with
a
baseline
dataset
from
normal
production
,
then
collect
defect
images
from
confirmed
scrap
,
known
rework
outcomes
,
and
misses
from
your
current
inspection
process
.
Use
a
sampling
rule
so
rare
-
but
-
costly
defects
(
like
missing
components
)
still
get
enough
coverage
.
Keep
camera
settings
,
lighting
,
and
orientation
consistent
,
and
store
images
with
metadata
:
product
type
,
station
ID
,
time
window
,
and
the
human
-
confirmed
label
.
Deployment Checklist: Make Vision Live Without Surprises
WATCH FOR
A
vision
model
without
containment
logic
only
creates
extra
inspection
.
Add
routing
first
,
then
add
lot
holds
for
defect
clusters
.
Start
with
a
pilot
station
or
limited
product
run
,
in
"
assist
mode
"
first
.
Track
disagreements
between
the
AI
and
inspectors
;
use
them
to
refine
labels
.
Move
to
"
automation
mode
"
only
for
the
labels
you
trust
usually
scrap
decisions
first
.
Run
a
per
-
shift
check
:
image
sharpness
plus
known
-
good
and
known
-
bad
reference
samples
.
Document
containment
actions
so
operators
know
exactly
what
to
do
for
every
label
.
CLOSE: MAKE DEFECT DETECTION PAY FOR ITSELF
Computer
vision
reduces
scrap
and
rework
when
you
connect
three
pieces
:
Detect
what
looks
wrong
,
Classify
it
into
labels
that
match
your
actions
,
and
Contain
the
outcome
so
defects
don
'
t
keep
flowing
.
Ask
yourself
:
do
you
already
have
a
clear
path
for
every
defect
label
the
AI
will
produce
?
If
yes
,
deploy
quickly
.
If
no
,
fix
containment
and
labeling
first
that
'
s
where
the
savings
show
up
.
Y
PA R T 3 : P R E D I C T I N G M AT E R I A L R I S K
Forecast Supply with Demand
Signals
our
next
production
shortage
won
'
t
start
with
a
dramatic
"
out
of
stock
"
alert
.
It
starts
quietly
sales
orders
pick
up
,
lead
times
drift
longer
,
and
a
supplier
quietly
moves
you
to
the
back
of
the
loading
queue
.
By
the
time
the
missing
material
shows
up
on
the
shop
floor
,
you
'
ve
already
paid
for
the
damage
in
expediting
fees
,
overtime
,
and
rescheduling
.
Build the Demand-Lead-Time Fusion Model
Fuse
what
you
expect
to
build
(
sales
orders
and
demand
plans
)
with
how
long
it
takes
to
get
the
parts
(
lead
-
time
history
and
supplier
performance
),
then
add
operational
signals
that
tell
you
whether
the
supplier
will
actually
hit
the
date
.
Define
a
demand
calendar
that
matches
your
release
cadence
weekly
or
daily
.
For
each
finished
product
,
map
sales
demand
to
component
quantities
using
your
bill
of
materials
,
so
the
output
is
a
clean
table
of
component
demand
by
date
.
FIELD EXAMPLE PRIYA, SUPPLY CHAIN ANALYST
Priya
learned
this
after
one
late
shipment
of
a
machined
component
stopped
a
key
assembly
line
.
She
didn
'
t
need
a
magic
forecast
she
needed
a
repeatable
way
to
predict
material
needs
and
supplier
risk
early
,
using
signals
her
team
already
had
:
sales
demand
,
confirmed
lead
times
,
and
operational
status
.
That
'
s
exactly
what
the
Demand
-
Lead
-
Time
Fusion
Model
gives
you
.
Use
two
lead
-
time
concepts
:
planned
lead
time
(
what
you
promise
)
and
observed
lead
time
(
what
you
actually
get
,
calculated
as
receipt
date
minus
order
date
per
supplier
and
part
).
Compute
an
expected
arrival
date
for
each
requirement
by
subtracting
lead
time
from
the
need
date
if
expected
arrival
slips
past
your
need
date
,
treat
that
as
a
risk
event
.
Operational Signals: Forecasting "Current Reality"
Lead
-
time
history
forecasts
the
average
future
.
Operational
signals
forecast
current
reality
,
in
three
buckets
:
Priya
'
s
team
got
value
fast
tracking
one
signal
:
how
often
suppliers
changed
promised
dates
after
first
confirming
.
When
a
supplier
repeatedly
pushed
promises
later
,
that

Close the Loop
Every

Optimize Scheduling with
Constraint AI
schedule
doesn
'
t
fail
because
your
team
lacks
effort
.
It
fails
because
constraints
show
up
late
,
in
ways
spreadsheets
can
'
t
handle
cleanly
:
frequent
rescheduling
,
late
jobs
that
never
recover
,
and
changeovers
that
spike
because
the
plan
ignored
what
happens
between
runs
.
The Constraint Chessboard Scheduler Framework
Treat
scheduling
like
a
board
game
where
each
job
placement
must
follow
rules
.
The
AI
doesn
'
t
guess
a
best
schedule
it
searches
for
one
that
satisfies
your
constraints
and
optimizes
your
objective
,
usually
throughput
and
changeover
reduction
.
FIELD EXAMPLE MARCUS, MACHINE SHOP OWNER
Marcus
would
watch
the
shop
floor
"
go
sideways
"
in
small
,
predictable
ways
every
Monday
:
a
job
slipped
because
a
tool
holder
wasn
'
t
back
yet
,
another
got
bumped
for
a
safety
check
,
and
suddenly
half
the
schedule
looked
wrong
.
He
needed
a
scheduling
system
that
respected
real
constraints
and
still
found
a
workable
plan
fast
enough
to
matter
the
Constraint
Chessboard
Scheduler
.
Define
the
objective
for
example
,
reduce
total
changeover
minutes
while
keeping
due
dates
feasible
.
Define
the
board
the
time
buckets
and
machine
resources
the
schedule
covers
.
Define
the
pieces
jobs
with
processing
times
,
setup
requirements
,
and
readiness
status
.
Define
the
rules
the
constraints
the
scheduler
must
respect
.
Capture Constraints That Actually Affect Changeover
Start
with
constraint
types
that
directly
drive
setup
work
:
job
-
to
-
machine
compatibility
,
tooling
and
setup
state
,
labor
and
operator
availability
,
maintenance
windows
,
and
quality
holds
.
Then
add
the
constraints
that
protect
due
dates
and
flow
:
release
dates
and
job
readiness
(
material
,
drawings
,
pre
-
operations
)
and
sequence
-
dependent
setups
(
setup
time
that
changes
depending
on
the
previous
job
type
).
Build the Chessboard Inputs
You
need
three
clean
input
tables
.
The
jobs
table
covers
processing
time
,
due
date
,
eligible
machines
,
and
setup
requirements
.
The
resource
and
time
slots
table
sets
your
horizon
and
a
consistent
granularity
don
'
t
mix
minute
-
level
precision
for
one
job
with
shift
-
level
assumptions
for
another
.
The
setup
cost
matrix
is
where
changeover
reduction
becomes
real
group
jobs
by
part
family
or
process
type
and
estimate
setup
time
between
families
if
you
can
'
t
measure
every
pair
exactly
.
Encode
readiness
so
jobs
only
enter
the
board
when
material
and
prerequisites
arrive
,
and
optimize
for
changeover
minutes
plus
lateness
penalties
,
not
makespan
alone
.
PRACTICAL TAKEAWAY
You
win
when
your
objective
matches
what
costs
you
money
:
changeover
time
and
missed
commitments
not
just
"
minimize
time
"
on
paper
.
QUICK ACTION STEP
Write
down
the
top
5
constraints
your
team
overrides
manually
each
week
.
For
each
one
,
specify
what
data
you
already
have
tool
readiness
timestamps
,
operator
shift
calendars
,
maintenance
windows
,
job
release
dates
then
turn
those
into
"
hard
"
or
"
soft
"
rules
for
the
scheduler
.
Run the Solver, Then Tighten It Like a Planner
Start
with
a
baseline
run
that
respects
hard
constraints
machine
eligibility
,
maintenance
blocking
,
operator
coverage
,
tooling
readiness
.
Then
review
the
schedule
against
a
changeover
-
focused
checklist
:
does
it
group
similar
work
to
reduce
setup
frequency
?
Does
it
avoid
"
tool
thrashing
"?
Do
transitions
fit
within
real
setup
windows
?
Does
it
respect
job
readiness
?
After
the
first
run
,
tighten
soft
constraints
preferences
like
minimizing
changeover
or
limiting
setups
per
day
and
add
stability
rules
so
a
single
job
change
doesn
'
t
reshuffle
the
whole
plan
.
Marcus's Workflow
Marcus
builds
a
setup
cost
proxy
grouped
by
process
type
and
tooling
family
,
loads
jobs
with
readiness
from
material
arrival
and
drawing
release
,
blocks
maintenance
windows
and
operator
coverage
as
hard
constraints
,
and
runs
the
solver
with
an
objective
that
prioritizes
changeover
minutes
while
penalizing
lateness
.
When
a
job
slips
,
he
updates
only
the
affected
constraints
and
reruns
rather
than
rebuilding
the
whole
plan
and
forcing
the
floor
to
relearn
it
.
What to Measure So the AI Stays Honest
Changeover
minutes
per
machine
per
day
whether
the
solver
actually
reduces
setup
churn
.
Distinct
setups
per
shift
reveals
"
thrashing
"
even
when
total
minutes
look
acceptable
.
Schedule
stability
how
often
the
plan
changes
after
first
approval
.
Infeasible
start
attempts
job
starts
the
schedule
implies
that
you
can
'
t
actually
execute
.
CLOSING THOUGHT
Marcus
learned
to
stop
asking
for
"
better
schedules
"
and
start
asking
for
"
schedules
that
obey
the
board
rules
."
When
AI
follows
your
real
constraints
,
you
cut
the
waste
that
keeps
showing
up
in
downtime
reports
and
cost
sheets
,
week
after

Energy Cost Reduction with AI

your

you
,
your
factory
schedule
and
utility
meters
already
tell
the
truth
you
just
haven
'
t
turned
that
truth
into

.
The
goal
is
simple
:
predict
your
next

day
and
next

shift
energy
load
so
you
can
run
smarter
,
not
just
react
faster
.
Define Load in Plain Terms
For
most
mechanical
plants
,
load
means
total
kW
demand
(
how
much
power
you
pull
at
a
moment
)
and
kWh
consumption
(
how
much
energy
you
use
over
time
).
If
your
utility
charges
demand
fees
or
penalties
for
high
kW
peaks
,
kW
prediction
matters
most
.
If
your
biggest
pain
is
monthly
energy
spend
with
no
demand
spikes
,
kWh
optimization
matters
more
.
"Energy cost control starts with knowing what you will burn before you burn it."
FIELD EXAMPLE AISHA, SUSTAINABILITY & UTILITIES LEAD
Aisha
'

tried
to
"
reduce

"
but
couldn

t
explain
why
one
week
looked
cheap
and
the
next
looked
brutal
the
machines
didn
'
t
just
run
more
,
they
ran
differently
.
AI
helped
by
building
a
predictive
model
using
both
operational
signals
(
production
plan
,
line
states
,
schedules
)
and
facility
signals
(
outdoor
temperature
,
compressed
air
patterns
,
time
-

day
effects
),
outputting
a
forecast
curve
of
expected
kW
by
hour
and
kWh
by
day
,
with
confidence
ranges
.
What to Feed the AI So It Can Predict Load
Pull
at
least
36
months
of
interval
data
(
hourly
or
15-
minute
billing
data
works
)
and
align
it
with
operational
states
:
which
lines
ran
,
how
many
shifts
you
staffed
,
and
whether
high
-
energy
steps
heat
treating
,
curing
,
forging
,
large
motor
loads
,
major
compressor
stages
happened
during
those

.
Add

,
identify

.
If
a

Targeting Peak Demand
Many
utility
structures
punish
high
kW
demand
more
than
they
punish
total
energy
use
,
so
peak
management
is
often
the
fastest
path
to
real
savings
.
Pull
your
utility

,
identify
the

,
and
translate
it
into
an
internal
peak
target
kW
value
even
an
approximate
one
based
on
your
recent
worst
hours
is
enough
to
drive
behavior
.
Then
identify
your
top
peak
reducers
:
intermittent
high
-
energy
processes
,
compressed
air
staging
,
and
HVAC
or
auxiliary
systems
that
don
'
t
scale
down
with
production
.
Execute Peak Plans With a Weekly Feedback Loop
When
a
peak
still
happens
,
inspect
the
plan

CLOSING THOUGHT: MAKE ENERGY A REAL SCHEDULING VARIABLE
Energy

variable
you
can
control
:
forecast
when

will
rise
,
adjust

to
