41
Q

one-off

  • capital outlay is huge
43
Q

batch production

A
  • any quantity between 2 and several thousand
  • semi-skilled / skilled workforce
  • flexibility - ability to produce a wide range of different products
  • important that it is easy to switch from one product to the next with minimum down time / to adapt quickly to changes in demand
  • often operated as a modular / cell production system
44
Q

modular / cell production

A
  • use a number of production cells grouped together to manufacture a component / a sub-assembly
  • usually consist of - group of machines - assembly - inspection point
  • multi skilled workers
  • can be automated
45
Q

cell / team manufacturing

A
  • work stations are carefully positioned in a logical manner to ensure minimal and quick movements from one operation to the next
  • team is responsible for the production of their output
  • high job satisfaction
46
Q

what is the aim of lean production

A

get to the right place at the right time, in the right quantity to achieve perfect workforce

47
Q

what are the three groups of stock / inventory

A
  • materials and components
  • work in progress

Q

what needs to happen in just in time for it to work

A

goods needs to be manufactured as they are required

53
Q

benefits of just in time

A

less space
reduce cost
less risk of damage sue to less transport
goods are made to order
nothing manufactured that isnt required
less waste

A

take place throughout the production process and are performed in conjunction with strict guidance documentation produced by the company and the client
