A machine, person, facility, warehouse, means of transportation or
other asset with a limited capacity that fulfills a particular function in the supply chain.
In APO, the following resources can be modeled:
Resources whose capacity is determined by working time data. The
capacity of these resources is continuously available during working
hours. There are single-activity resources, on which only one activity
can be processed at any one time, and multi-activity resources, on which several activities can be processed simultaneously.
Single-activity resources and multi-activity resources are used for
scheduling in the APO components Capable-to-Match (CTM) and Production
Planning and Detailed Scheduling (PP/DS), in which production dates of orders and operations are scheduled in seconds.
Bucket resources, whose capacities are defined by quantities (for
example, transport or warehouse capacities) or by daily rates (for
example, production rates). Bucket resources are used for scheduling in
Supply Network Planning (SNP). The most detailed scheduling that can be done is on a daily basis.
