4.1.6 Process Type Assignment

Process types may have assignments indicating re-usable resource types for which occurrences may be consumed or occupied by occurrences of the process type. An example of such assignment is a concrete mixer resource type for delivering concrete.

The following diagram shows the generic classes and relationships used when applying this concept. In addition, concepts may have particular importance to common or standardised industry practices and scenarios. For these specific usage scenarios, the tables below shows a recommended list of general usage patterns that users may adopt.
