Features of inventory management control systems (6)
- maximum/economic inventory level
- minimum inventory level
- re-order level
- re-order quantity
- lead time
- buffer inventory
maximum inventory level description and justification
- this is the most amount of inventory that should be held
- avoid consequences of over stocking
minimum inventory level description and justification
- this is the least amount of inventory that should be held
- avoids consequences of under stocking
re-order level description and justification

producing products using machinery or equipment. can use automation (only computer aided manufacturing) or mechanisation(labour and machines working together)
automation advantages (5)

what is labour intensive production
when humans do most of the work
