Template: OASIS:PartAssembly

This section specifies the template PartAssembly.

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 PartAssembly template.

The specification comprises the following sections:

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

The PartAssembly template describes how to represent the parent/child relationship betwen design parts (a design assembly).

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

Figure 1 -  Assembly structure

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

NOTE    The PartAssembly 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 constraints shown on the template's SysML Block are described in the template constraints 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:
parent [1] (Template: OASIS:Part)
The parent Part
child [1] (Template: OASIS:Part)
The child Part
Parts:
effectivityRole [0..1] (Template: OASIS:Classifier)
The role of the effectivity
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

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 when the assembly relationship ends to be valid

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')

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.

The following constraints are defined for this template:

Constraint: viewsMustBeProvided
Specification: (English)
parent.ViewDefinitionContext not null and child.ViewDefinitionContext not null

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 PartAssembly.

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.

Figure 3 -  Parametric diagram for PartAssembly

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:classPartAssembly [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)
Private Part Property:de [0..1] (Template: OASIS:DatedEffectivity)

Figure 3 shows the instances that have been instantiated in the template. These are used to set the default value of blocks.
