Q

how can tracking of materials, tools, equipment and products be done

A

automatically by tagging

17
Q

how do tags help with tracking items in factories

A

they can be scanned or detected so a status can be kept up to date in a computer system

18
Q

what are the uses of tracking items in a factory

A

monitoring stock levels,
monitoring movement of products, number of finished products

19
Q

in modern automated factories info can be passed around by ..

A

smart machines

20
Q

what can human workers used to share info

A

internet based communication systems

21
Q

what is specialised buildings

A

factories being designed to incorporate smart technology and minimise environmental impact

22
Q

in specialised buildings technological advances can lead to…

A

a reduced need for room

23
Q

what does FMS stand for

A

Flexible manufacturing systems

24
Q

what is FMS

A

a set of different machines which carry out the different stages of production

25
what do the computer-controlled automated systems in FMS do
transport materials through different processes then store finished product
26
what is FMS called Flexible
the system is easy to adapt
27
what are the aims of lean manufacturing
minimise: amount of resources used, waste produced, costs maximise: efficiency
28
what is an example of a lean manufacturing system
Just-In-Time system of stock control (JIT)
29
what does JIT stand for
Just-In-Time
30
what is the main advantage of JIT
saves money when works
31
what is the main disadvantage of JIT
lose money if something goes wrong
32
what are the two things JIT relies on to work properly
things being delivered on time and fault free
