Maintenance Ontology

Maturity: 🟢 Released

IRI: https://spec.industrialontologies.org/ontology/maintenance/Maintenance/

The purpose of this IOF Maintenance Reference ontology is to support semantic interoperatibility through the use modular ontologies in the maintenance domain. This Ontology contains terms and concepts identified as common in a number of application ontologies for maintenance management, maintenance procedures, asset failure and failure modes and effects analysis. The ontology is aligned with the IOF Core Ontology which is aligned with Basic Formal Ontology and importas terms for other domain independent ontologies.

Class Definition
degraded state state of reduced ability to perform as required but with acceptable reduced performance
disposition to exhibit undesirable behavior disposition of an item that would not be expected under normal operating conditions
disposition to fail disposition of an item to undergo a failure process
failed state state of an item being unable to perform a required function due to a failure event
failure effect process that is the consequence of failure, within or beyond the boundary of the failed item
failure event event that causes an item to lose its ability to perform a required function
failure mode code information content entity that describes an undesireable disposition
failure process process that changes some quality of an item causing the item to become degraded or failed
functioning process process in which an item performs its function
maintenance activity maintenance process that is a single task to retain or restore the function of a maintainable material item
maintenance process process to do with retaining or restoring the function of a maintainable material item under a maintenance strategy
maintenance state stasis that holds during a temporal interval when the realizable functions and capabilities of the participating item, or the grad…
maintenance strategy maintenance (method/ approach/ actions) to enable (the/an) asset to achieve (management’s/ desired) objectives
maintenance work order record information content entity that describes a maintenance process
operating state state of an item being able to perform a required function
qualification specification requirement specification that identifies the need for a person to have an assessed skill for a specific task
qualified maintenance person person who is qualified to perform a specified specified maintenance activity
required function function of a maintainable material item which is considered necessary to fulfil a process requirement
supporting maintenance activity single action in support of the execution of a maintenance process
