This section specifies the template ValidElementRealization.
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 ValidElementRealization template.
The specification comprises the following sections:
- Section Description provides a
description of the template;
- Section Template Block specifies the SysML
Block that represents the template;
- Section Template Properties specifies
the properties, i.e. the SysML Part, Reference and Value properties of the
templates SysML Block;
- Section Template Output Ports
specifies the SysML Output Ports of the templates SysML Block. These bind to the
templates and PLCS PSM objects
instantiated by the ValidElementRealization template as
described in section Template
Parametric Diagram;
- Section Template Constraints specifies
the constraints on PLCS PSMTemplate objects instantiated by the
ValidElementRealization template;
- Section Template Parametric
Diagram specifies the templates and PLCS PSMTemplate objects instantiated by the
ValidElementRealization template;
- Section Instantiated blocks specifies
the templates and PLCS PSMTemplate objects instantiated by the
ValidElementRealization template and bound to private
parts of the template;
- Section Default instances species the
instances that have been instantiated in the template. These are used to set
the default value of blocks.
- Section Constraint blocks identifies the
constraint blocks that have been specified in this template;
- Section Example data
provides example XML data sets that have been instantiated in accordance
with this template.
NOTE
An explanation of a template and its specification is provided in
the
Template
overviewThe ValidElementRealization template describes how to represent the relationship between
an element in a physical structure and items of supply or part definitions that may
be validly fitted as the element in question. The validity may be time limited and
other constraints on validity may be documented.
No templates have been explicitly defined as being related to the ValidElementRealization template.
NOTE
The ValidElementRealization template may make reference
to other templates as part of the Parametric Diagram. These are not listed
here.
Figure 1 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.

The following SysML Part, Reference, and Value properties are defined for this template:
References:
item [1] (Template: SwedishDefence:
ItemDefinition)
Relationship to the item definition that is realized.
physicalElement [1] (Template: SwedishDefence:

OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
standardItem [1] (ValueType:
ExternalOwlClass)
The characterization of the valid element realization as standard or non-standard.
The reference data used is restricted to the following set:
setpointValue [0..*] (Template: SwedishDefence:
PropertyValue)
The desired (expected) values of the Operational Properties that shall be followed-up
for a Physical Element (pos), given Operating Mode.
The reference data used in Template: SwedishDefence:
PropertyValue is restricted as follows:
RDL constraint 1:setpointValue constraint
The reference data for:
OASIS:PropertyValueNumeric.property -> ExternalOwlObject.individual
is restricted to the following individual:
aggregatedMTBF [0..1] (Template: SwedishDefence:
PropertyValue)
An indication of how often an ItemDefinition may break in the current location, regardless
of fault mode, that is used for simulation and planning. (MTBF = Mean Time Between
Failure).
The reference data used in Template: SwedishDefence:
PropertyValue is restricted as follows:
RDL constraint 1:aggregatedMTBF constraint
The reference data for:
OASIS:PropertyValueNumeric.property -> ExternalOwlObject.individual
is restricted to the following individual:
longevityAsCalculated [0..*] (Template: SwedishDefence:
PropertyValue)
Life expectancy of the item definition for a certain operating mode (as compared to
longevityAsCalculated on Item Definition).
Values:
validRealizationToDate [0..1] (Block: Ap239Ap233Psm:
DateTimeString)
The data and time until which the element realization was valid.
The following constraint, normally a uniqueness constraint, is
applicable when instantiating the DateTimeString:
rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: XSDDATETIMESpecification: (OCL2.0)
self.matches('[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}Z')
validRealizationFromDate [1] (Block: Ap239Ap233Psm:
DateTimeString)
The data and time from which the element realization became valid.
The following constraint, normally a uniqueness constraint, is
applicable when instantiating the DateTimeString:
rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: XSDDATETIMESpecification: (OCL2.0)
self.matches('[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}Z')
The following output ports are defined for this template:
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 ValidElementRealization.
The public properties, i.e. those visible in the template's SysML block (See Figure 1) 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.

There are no instances that have been instantiated in this template.
Figure 3 shows the constraint blocks that have been created in the template.
Constraint Blocks are typically used to combine blocks into a collection that
can then be bound to a property. For example, combining a set of identifications
that can then be bound to property of type Identification.

The following constraint blocks have been created:
Constraint: PartOrResourceItemSpecification: (OCL2.0)
partOrResourceItem = if not part.oclIsUndefined() then part
else resourceItem endif
