Kunnossapitohallintajärjestelmät

Kunnossapito, in Finnish, refers to the systematic care and upkeep of assets to preserve their functionality, safety, and efficiency. It covers activities aimed at machines, equipment, buildings, infrastructure, and other physical assets throughout their life cycles. The goal is to prevent failures, extend service life, reduce downtime, and optimize total costs.

Maintenance activities typically include inspection, cleaning, lubrication, calibration, adjustment, repair, replacement of worn components, and testing after interventions. These tasks are planned and carried out according to a maintenance strategy that balances reliability with operating costs. Common approaches are preventive maintenance, which is scheduled based on time or usage; predictive or condition-based maintenance, which relies on real-time measurements and data; and corrective or reactive maintenance, which responds to faults after they occur. Proactive methods such as reliability-centered maintenance and total productive maintenance aim to optimize system performance and operator involvement.

The maintenance process often relies on formal planning, work orders, spare-part management, and documentation within a maintenance management system or computerized maintenance management system (CMMS). Key performance indicators include mean time between failures (MTBF), mean time to repair (MTTR), and overall equipment effectiveness (OEE), used to assess reliability and efficiency. ISO standards such as ISO 55001 (Asset Management) and ISO 9001 (Quality Management) provide frameworks for governance and continual improvement.

Benefits of effective kunnossapito include higher asset reliability, safer operations, energy efficiency, and better budgeting through lifecycle costing. Challenges may involve aging infrastructure, data quality and integration, skilled labor availability, and aligning maintenance with production or service schedules. In practice, kunnossapito supports operational continuity and long-term value for organizations managing physical assets.
