4.1.11 Resource Type Assignment

Resource types may have assignments indicating re-usable product types for which occurrences may be sourced by occurrences of the resource type. An example of such assignment is a particular crane model that may be used for a crane equipment resource used for erecting steel.

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.
