primitiveRationale = “As a disposition will come into its existance prior to its realization in a failure process necessary and sufficient conditions can not be created at this point due to a lack of patterns to express process types regardless of the time of their existence”

Annotations

primitiveRationale = “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.”

Annotations

explanatoryNote = “Qualified person on its own is not particularly useful unless reasoning is constrained to only the individuals of interest at some time. Specific subtypes of qualified person are necessary to determine if specific qualification types are satisfied. Still, care must be taken when reasoning over temporal information as, if the critieria are met at some time, the classification will hold.”

IRI: https://spec.industrialontologies.org/ontology/construct/UndesireableDisposition

Annotations

label = “undesireable disposition”@en-US
explanatoryNote = “There are two subclasses, disposition to fail and disposition to exhibit undesirable behavior. We need to distinguish between the disposition to leak which is realised in a leaking process (regarded as a failure) and the disposition to overheat realised in a heating process (which, in this example) is not a failure process). We asset that disposition to exhibit undesirable behavior is the disposition of an item that would not be expected under normal operating conditions but may occur such as vibration or overheating.”
