CASE PREMIUM PAPER (50%)
Company “Premium Paper” is located near Paris. The design and print paper for
furniture applications (usually called melamine paper). Production process consists on
printing raw paper. Raw paper is delivered in big rolls (700 Kgs). Production process is done
in multi-stage printing machines. Each stage of the machine contains an engraved cylinder
and ink. Paper runs on the different stages and the combination of all of them provides the
final printed paper.
Set up times in these machines are very long (3/4 hours). This means that every time the
process is stopped because of any technical issue, the costs can be enormous.

a breakdown they run and try to fix it as soon as possible. However due to some unexpected
failures and lack of spare parts, “Premium Paper” is suffering very serious productivity
problems.
