Production Planning for Process Industries (PP-PI)

Storage or production unit that combines the functions of storage facilities (for example, inventory management) and resources (for example, capacity requirements planning).

Storage resources link a storage location to a resource and can be used for intermediate storage of materials during production. Their capacities are not only defined based on time, but also based on quantity.

The following types of storage resource are distinguished:

• Storage resources that are only used for storing materials

These storage resources are available for storage continuously over time. During planning, they are only considered with regard to their stocks.

• Storage resources where production processes also take place

During planning, these storage resources are considered both with regard to their stock level, as well as their commitment based on time.
