Template: OASIS:SystemBreakdown

This section specifies the template SystemBreakdown.

The specification comprises a SysML Block that represents the template and an associated Parametric Diagram that defines the templates and PLCS PSMTemplate objects instantiated by the SystemBreakdown template.

The specification comprises the following sections:

NOTE    An explanation of a template and its specification is provided in the Template overview

The SystemBreakdown template describes how to represent the decomposition of systems for a product

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

Figure 1 -  System Breakdown model

No templates have been explicitly defined as being related to the SystemBreakdown template.

NOTE    The SystemBreakdown template may make reference to other templates as part of the Parametric Diagram. These are not listed here.

Figure 2 shows the SysML Block that represents the template. The Block is an abstraction representing a pattern of templates and PLCS PSMTemplate objects.

The properties, i.e. the SysML Block Part, Reference and Value properties, of the template's SysML Block are described in the Template Properties section.

The output ports shown on the template's SysML Block are described in the template output ports section.

The SysML Parametric diagrams for the template Block are shown in template parametric diagram section.

Figure 2 -  Template block definition diagram for SystemBreakdown

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

References:
breakdownOf [1] (Block: Ap239Ap233Psm:BreakdownOfSelect)
The product that has been broken down.
Parts:
ids [1..*] (Template: OASIS:Identification)
The identifiers of the breakdown There shall be at least one identifier that is the breakdown_id. Hence there shall be at least one identifier classified to be a "Breakdown_identification_code" or a sub-class of "Breakdown_identification_code".
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
There must be one identifier that is the breakdown identifier.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
versionIds [0..*] (Template: OASIS:Identification)
The identifiers of the SystemBreakdownVersion.
NOTE    If no versionIds are specified a unique, unidentified SystemBreakdownVersion is created.
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
The identifiers must be version identifiers.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
classifications [0..*] (Template: OASIS:Classifier)
The classification of the SystemBreakdown
The reference data used in Template: OASIS:Classifier is restricted as follows:
RDL constraint 1:
The reference data for:
OASIS:Classifier.class -> ExternalOwlClass.class
is restricted to classes that are subclasses of the following class:
descriptions [0..*] (Template: OASIS:Descriptor)
The descriptions of the SystemBreakdown.
names [0..*] (Template: OASIS:Name)
The names of the SystemBreakdown.

The following output ports are defined for this template:

sysbkdn (Block: Ap239Ap233Psm:SystemBreakdown)
Enables the Block: Ap239Ap233Psm:SystemBreakdown instantiated by this template to be referenced when the template is used.
sysbkdn_vn (Block: Ap239Ap233Psm:SystemBreakdownVersion)
Enables the Block: Ap239Ap233Psm:SystemBreakdownVersion instantiated by this template to be referenced when the template is used.
sysbkdn_of (Block: Ap239Ap233Psm:BreakdownOf)
Enables the Block: Ap239Ap233Psm:BreakdownOf instantiated by this template to be referenced when the template is used.

There are no constraints defined for this template.

This section describes the template's Parametric Diagram. The diagram details the pattern of templates and PLCS PSMTemplate objects that are required to represent the template SystemBreakdown.

The public properties, i.e. those visible in the template's SysML block (See Figure 2) are shown on the left of a Parametric Diagram.

NOTE    Restrictions on the reference data to be set on the public properties is defined in the Template Properties section.

The output ports are shown on the right of a Parametric Diagram.

PLCS PSM objects are shaded khaki and Templates are shaded light green in a Parametric Diagram.

The following blocks are instantiated by this template and bound to private parts of the template as shown in the Parametric Diagram section:

Private Part Property:systemBreakdown [1] (Block: Ap239Ap233Psm:SystemBreakdown)
Private Part Property:systemBreakdownVersion [1] (Block: Ap239Ap233Psm:SystemBreakdownVersion)
Private Part Property:systemBreakdownOf [1] (Block: Ap239Ap233Psm:BreakdownOf)

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

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: UR1
Specification: (OCL2.0)
BreakdownOf::allInstances()->isUnique(Sequence{breakdown, ofView})
Private Part Property:combNameAndDesc [1] (Constraint Block: OASIS:Name:CombineNamesAndDescriptors)

There are no instances that have been instantiated in this template.

There are no constraint blocks defined in this template.

No example data sets have been provided for this Template.
