Template:- OASIS:FunctionalBreakdownStructure

The FunctionalBreakdownStructure template describes how to represent a relationship between a FunctionalElementDefinition and another FunctionalElementDefinition that is a constituent.

The SysML Block Definition diagram in Figure 1 shows how a functional breakdown is represented in the PLCS PSM.

Template Properties

The following SysML Part, Reference, and Value properties are defined for this template:

References:
child [1] (Block: Ap239Ap233Psm:FunctionalElementDefinition)
The constituent FunctionalElementDefinition.
parent [1] (Block: Ap239Ap233Psm:FunctionalElementDefinition)
Parts:
ids [0..*] (Template: OASIS:Identification)
The collection of identifiers of the FunctionalElementUsage.
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
The id must be classified as a Functional_element_usage_identification_code or a subclass thereof.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
effectivityRole [0..1] (Template: OASIS:Classifier)
A classification of the EffectivityAssignment.
structureRole [0..1] (Template: OASIS:Classifier)
A classification of the FunctionalElementUsage.
Values:
startEffectivityDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)
The date that defines the lower bound of the interval of applicability.

The following constraint, normally a uniqueness constraint, is applicable when instantiating the DateTimeString:

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: XSDDATETIME
Specification: (OCL2.0)
self.matches('[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}Z')
endEffectivityDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)
The date that defines the upper bound of the interval of applicability. The value of the attribute need not be specified. If the value for this attribute is not specified, the interval of applicability has no upper limit.

The following constraint, normally a uniqueness constraint, is applicable when instantiating the DateTimeString:

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: XSDDATETIME
Specification: (OCL2.0)
self.matches('[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}Z')
