In corrugated plants, a high percentage of all orders comes from a small number of customers who place orders in a regular pattern, but often very late, only a short time before production starts.
Obviously, Sales must keep capacity free for those guaranteed orders until they arrive. With Capacity Reservations, the known required capacity can be reserved machine by machine, and the reserved capacity is automatically released when the actual orders arrive. The TGV Machine Load then shows the remaining free capacity for other orders, and does not create a false impression of too little work where machines are actually almost fully loaded.
Capacity Reservations can be made in several different categories:
Customer Reservations are the most relevant of those categories. The system knows the number of hours to be blocked per week (or per day) for each customer and each machine, and automatically applies the same standard reservations for each new week.
Stock Reservations are an example of other categories for which capacity can be reserved.
The Planning Reservation finally allows Planning to keep a safety margin on selected (or all) machines. Contrary to the other reservations, that number of hours is never released automatically, but Planning must do so manually when they feel the time has come.
To let PC-Topp know for which orders it must release a corresponding part of the reservation when the order arrives, the order must be marked by a Reservation Code in the order data transfer. That code can be, for example, S for the Stock Reservations, and C for the Customer Reservations: An order that has a reservation code C for one of the special customers for which there can be reservations (the "Service Customers") reduces the capacity reserved for that customer, an order with an S reserves the Stock Reserve.
(That means that an order for a service customer without the C will not affect the reservation, which is exactly right when a Service Customer places some extra order, which should not reduce the room reserved for the regular orders of that customer.)
The Capacity Reservations page visualizes the reservations and the resulting machine load in a TGV-like timeline as well as in a bar diagram to make it as easy as possible to identify bottlenecks and available capacity.
