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.

Premium paper has 6 printing lines (3 "Stoner" Machines , 2 "Rotomec" Machines and 1 "Grimaldi" Machine (the oldest one).

Premium Paper has a highly experienced maintenance team. Every time a machine suffers 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.

How should you define the maintenance process? Which changes should you implement in terms of maintenance? Which recommendations should you address to the Top Management with respect the machines park?
