Definition
state of an item being able to perform a required function
Explanatory Notes
In defining the state of an item as being able to perform a required function, we are assuming that the external resources, if required, are provided
Note that in an operating state the item may be functional (so in the operating state) and not currently operating (performing in the functioning process)
Examples
- running at desired speed, producing required power, pumping desired volume
Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
generally speaking, the determination of maintenance state is determined from outside of the ontology, e.g., through analytics, other reasoning mechanims, or by reports from the device or control system, and so is not determinable from the ontology alone. The required constructs for creation of a formal definition are not available in this release.
Formal Axioms
First-Order Logic Axioms
OperatingState(x) → MaintenanceState(x)
Semi-Formal Natural Language Axioms
if x is a ‘operating state’ then x is a ‘maintenance state’
