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 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:
