According to the Oracle Manufacturing Cloud User Guide, a work area represents a physical,
geographical, or logical cluster of work centers. A work area can contain one or more resources that
perform similar operations or activities. A resource instance (A) is an individual machine, tool,
person, or crew that performs an operation in a work definition. A resource (B) is a generic
representation of a resource instance that defines its attributes, such as cost, availability, and
capacity. A manufacturing calendar (D) is a calendar that defines the working days and hours for a
plant or a work area.
