Hooldusaegu

Hooldusaegu is a planning concept in maintenance and operations management that designates the scheduled window allocated for preventive maintenance, inspection, and related activities within a production or service cycle. The term is used in discussions of reliability engineering and asset management to contrast planned maintenance with unplanned downtime caused by equipment failure. In practice, hooldusaegu aims to balance the need for regular servicing with the demand for continuous operation, seeking to reduce unplanned outages and extend asset life.

In application, it is used across industries such as manufacturing, power generation, and data centers. A hooldusaegu may be aligned with shift patterns, calendar dates, or production milestones. Typical tasks include lubrication, calibration, component replacements, cleaning, and software updates. The length and timing depend on asset criticality, manufacturer recommendations, regulatory requirements, and risk assessments.

Implementation and metrics: Effective hooldusaegu planning requires asset inventories, failure mode analyses, and integrated scheduling with production planning and maintenance management systems. It is often supported by risk-based maintenance and predictive analytics. Key metrics include maintenance on time, planned versus unplanned maintenance ratio, uptime, MTBF, MTTR, and maintenance backlog. Challenges include accurate asset data, coordination across departments, and ensuring that maintenance does not degrade service levels.
