fennntartása

Fenntartása (the correct form is fenntartása; fennntartása is a common misspelling) is a Hungarian noun meaning maintenance or upkeep—the set of activities that keep a system, structure, or organization in good working order over time. It covers preserving, repairing, and renewing components to prevent deterioration and to sustain functionality.

The term is used across many contexts, including infrastructure (buildings, roads, public facilities), machinery and equipment, information technology, and organizational management. In everyday language it often appears with references to maintenance costs (fenntartási költségek) and the party responsible for upkeep (fenntartó).

Maintenance activities can be categorized by approach. Preventive maintenance (megelőző karbantartás) involves planned inspections and replacements to prevent faults. Corrective maintenance (hibajavítás) addresses faults after they occur. Predictive maintenance (előrejelző karbantartás) uses data and analytics to forecast when maintenance should occur. Routine tasks such as cleaning, lubrication, calibration, software updates, and backups are common components of fenntartása.

Management of fenntartása often relies on formal maintenance plans, service contracts, and allocated budgets. It is closely linked to asset management, lifecycle management, and, in information technology, to change and patch management. Effective fenntartása reduces risk, extends service life, and can lower total cost of ownership by minimizing unplanned downtime.

Related concepts include üzemeltetés (operation) and karbantartás (maintenance) in various industries; terminology and emphasis can vary by sector.
