is

digital

twin

is

a

digital

model

or

replica

of

aphysical

asset,

be

it

a

product,

an

organisation,

apublic

infrastructure

or

even

an

entire

city.

It

has

awide

range

of

applications

–

from

conductingdiagnostics

on

organisational

health,

augmentingservice

designs

to

enabling

more

effective

citymanagement.

In

the

context

of

a

smart

city,adigital

twin

of

the

city

continuously

collectsinformation

from

the

built

environment

(viatechnologies

such

as

sensors,

drones,

or

mobiledevices).

It

is

made

possible

with

the

use

of

remote

communication

technologies

such

as

WiFi

and

Bluetooth

as

well

as

through

Internet

of

Things(IoT)

sensors

that

gather

data

from

the

physicalworld

to

reconstruct

an

identical

digital

copy

of

thecity.

Apart

from

IoT,

the

use

of

Big

Data,

ArtificialIntelligence

(AI),

cloud

computing,

machine

learning

and

advanced

analytics

also

enhance

theaccuracy

and

dynamism

of

this

replica,

allowingstatic,

historical

and

real-

time

data

to

be

processed

and

synthesised

almost

immediately

toprovide

valuable

insights

about

the

performanceof

the

city.

Therefore,

a

digital

twin

can

beconsidered

as

a

“strategy

accelerator”

thatfacilitates

public

organisations

to

identifyinsights

and

more
