Template: OASIS:RealizedPartAssembly
Introduction

This section specifies the template RealizedPartAssembly.

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

The specification comprises the following sections:

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

The RealizedPartAssembly template describes how to represent the parent/child relationship betwen parts in the real world (a realized assembly)

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

Related Templates

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

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

Figure 2 shows the SysML Block that represents the template. The Block is an abstraction representing a pattern of templates and PLCS PSM 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 constraints shown on the template's SysML Block are described in the template constraints section.

Template Properties

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

References:
parent [1] (Template: OASIS:RealizedPart)
The parent real part
child [1] (Block: Ap239Ap233Psm:ProductViewDefinition)
The child part really used in the parent

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

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: ur1
Specification: (OCL2.0)
ProductViewDefinition::allInstances()->isUnique(Sequence{viewDefinitionOf, initialContext})
effectivityRole [0..1] (Template: OASIS:Classifier)
The role of the effectivity
Parts:
locationIndicators [0..*] (Template: OASIS:Identification)
The collection of Identifiers that identifies the usage of the child in the assembly in a diagram, list, chart, or on a physical piece of equipment.
quantity [0..1] (Block: Ap239Ap233Psm:ValueWithUnit)
The amount of the child in the assembly.
Values:
startEffectivityDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)
The date when the assembly relationship starts to be valid
endEffectivityDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)
The date when the assembly relationship ends to be valid
Template Output Ports

The following output ports are defined for this template:

assembly (Block: Ap239Ap233Psm:NextAssemblyViewUsage)
Enables the Block: Ap239Ap233Psm:NextAssemblyViewUsage instantiated by this template to be referenced when the template is used.
Template constraints

The following constraints are defined for this template:

Constraint: parentViewMustBeProvided
Specification: (English)
parent.ViewDefinitionContext not null
Constraint: childTypeRestriction
Specification: (English)
child must be an instance of either PartViewDefinition or ProductAsIndividualView
Template Parametric diagram

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

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 the Parametric Diagram.

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

Instantiated Blocks

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:nau [1] (Block: Ap239Ap233Psm:NextAssemblyViewUsage)
Private Part Property:classifyNAU [1] (Template: OASIS:Classifier)
Private Reference Property:classRealizedPartAss [1] (Block: Ap239Ap233Psm:ExternalOwlClass)

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

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: ur1
Specification: (OCL2.0)
ExternalOwlClass::allInstances()->isUnique(class)
