4.2.403 Process_operation_occurrence_relationship

A Process_operation_occurrence_relationship is a relationship between two Process_operation_occurrence objects.

NOTE The relating Process_operation_occurrence and the related Process_operation_occurrence need not belong to the same Process_plan_version.

The data associated with a Process_operation_occurrence_relationship are the following:

4.2.403.1 cycle_time

The cycle_time specifies the interval of time within which both Process_operation_occurrence objects have to take place in order to be declared as simultaneous.

The cycle_time need not be specified for a particular Process_operation_occurrence_relationship.

4.2.403.2 description

The description specifies additional information about the Process_operation_occurrence_relationship.

See process_operation_occurrence_relationship to multi_language_string for the application assertion.

The description need not be specified for a particular Process_operation_occurrence_relationship.

If present, there shall be exactly one object that defines the description for a Process_operation_occurrence_relationship.

4.2.403.3 related

The related specifies the second of the two Process_operation_occurrence objects related by a Process_operation_occurrence_relationship.

NOTE The semantics of this attribute are defined by the attribute relation_type.

See process_operation_occurrence_relationship to process_operation_occurrence for the application assertion.

4.2.403.4 relating

The relating specifies the first of the two Process_operation_occurrence objects related by a Process_operation_occurrence_relationship.

NOTE The semantics of this attribute are defined by the attribute relation_type.

See process_operation_occurrence_relationship to process_operation_occurrence for the application assertion.

4.2.403.5 relation_type

The relation_type specifies the meaning of the relationship.

Where applicable the following values shall be used:

4.2.403.6 waiting_time

The waiting_time specifies the time which shall elapse, at least, between the completion of the relating Process_operation_occurrence and the start of the related Process_operation_occurrence. The referenced shall have a definition that is a Duration_property.

EXAMPLE The Process_operation_occurrence 'polishing' must not be started less than 2 hours after the Process_operation_occurrence 'painting' ended.

See process_operation_occurrence_relationship to property_value for the application assertion.

The waiting_time need not be specified for a particular Process_operation_occurrence_relationship.
