This section specifies the template ItemDefinition.
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 ItemDefinition 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 ItemDefinition template as
described in section Template
Parametric Diagram;
- Section Template Constraints specifies
the constraints on PLCS PSMTemplate objects instantiated by the
ItemDefinition template;
- Section Template Parametric
Diagram specifies the templates and PLCS PSMTemplate objects instantiated by the
ItemDefinition template;
- Section Instantiated blocks specifies
the templates and PLCS PSMTemplate objects instantiated by the
ItemDefinition 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
overview
The ItemDefinition template is an abstract template subtyped into either an ItemOfSupply
(used for materiel that has an identifier owned by the Swedish Defence) or a PartDefinition
(typically materiel that has only the supplier's or manufacturer's part number as
identifier). There are traditionally five categories of ItemDefinition: Materiel;
Ammunition; Food; Fuel, Medical supply.
The following templates are related to the ItemDefinition template:
NOTE
The ItemDefinition 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.
Figure 1 - Template block definition diagram for ItemDefinition
The following SysML Part, Reference, and Value properties are defined for this template:
Parts:
longevity [0..1] (Template: OASIS:
PropertyValueNumeric)
Life expectancy of the Item Definition as provided by the supplier (without taking
in consideration the actual operating mode etc.)
The reference data used in Template: OASIS:
PropertyValueNumeric is restricted as follows:
RDL constraint 1:longevity constraint
The reference data for:
OASIS:PropertyValueNumeric.unit -> ExternalOwlObject.individual
is restricted to the following individual:
RDL constraint 2:longevity constraint
The reference data for:
OASIS:PropertyValueNumeric.property -> ExternalOwlObject.individual
is restricted to the following individual:
meanTimeBetweenFailure [0..1] (Template: OASIS:
PropertyValueNumeric)
The estimated value for established component types (Item Definitions). Note that
this value will not necessarily tell how well the item of supply individual will perform
in the field under different environmental and operating conditions - as opposed to
the aggregated Mean Time Between Failure value as indicated on the Valid Element Realization
of the Physical Maintenance Structure (PhysicalBreakdown).
The reference data used in Template: OASIS:
PropertyValueNumeric is restricted as follows:
RDL constraint 1:meanTimeBetweenFailure constraint
The reference data for:
OASIS:PropertyValueNumeric.property -> ExternalOwlObject.individual
is restricted to the following individual:
The following output ports are defined for this template:
OASISpart (Template: OASIS:
Part)
Enables the
Template: OASIS:
Part instantiated by this template to be referenced
when the template is used.
PSMpart (Block: Ap239Ap233Psm:
Part)
Enables the
Block: Ap239Ap233Psm:
Part 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 ItemDefinition.
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.
Figure 2 - ItemDefinition
The following blocks are instantiated by this template and bound to private parts
of the
template as shown in the Parametric Diagram
section:
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.
