Supply Systems 
deal with how parts are replenished and connect parts to a particular replenishment system type, source area and notification output methods.
Output methods deal with the way in which notification is sent that replenishment is necessary.
There are 5 main replenishment system types in PFEP. Each of these types (can also be thought of as delivery methods) incorporates a certain logic to enabling replenishment of parts.
Kanban - These are parts that are replenished based on MIN-MAX logic. Typically there are two or more containers being maintained line side; once one (or another specified number) of containers reaches the MIN mark, a request for a new container is made.
Kitting - These are parts for sequenced units that are put on carts and delivered to the line. A single cart can contain parts for a single unit or multiple units. The carts are typically loaded well ahead of the units reaching the line. The list of parts to be placed on the cart is calculated by looking at the production schedule and order configuration.
Direct - These are parts that are delivered directly to the line upon being received. Typically these are vendor managed parts, where the replenishment is handled by the part vendors.
Sequenced - These are parts for multiple sequential units put on a single cart, arranged in sequential order of use. This system operates like the Kitting system, but with the added factor of specifically arranged parts.
Unit Kitting - A unit kit is one that contains parts for one unit, is delivered to a particular location on the line, and then moves with the unit. Parts are consumed from the cart as it moves along the line.
