Explanation / Answer

24

a

Customer arrival is not consistent

25

c

In pooled system demand is shared across all servers

26

d

Here demand rate is less than capacity

27

c

work overtime is requirement not waste

28

a

OEE calculates effective usable time

29

b

A process flow diagram shows where time is wasted

30

c

In lean waste is reduced

31

c

it is a pull system based on demand
