Maintenance Strategies
Organizations use a variety of maintenance strategies to manage their assets effectively. The systems are broadly classified into:
- Reactive maintenance: This strategy, also known as "breakdown" or "run to failure" care, involves only fixing the equipment when it breaks. It is suitable for assets that are not critical and have low downtime costs. Still, it can become expensive and disruptive when used on equipment, which is crucial.
- Maintenance Preventive: The strategy involves scheduling regular maintenance, regardless of equipment condition. The goal of preventive care is to avoid failures through the replacement or refurbishment of components before they wear out. It can reduce the likelihood of unplanned breakdowns. Still, it may also result in excessive maintenance on equipment in good shape.
- Maintenance Predictive: Data and analytics are used to determine when maintenance on equipment is required. By collecting and monitoring data and continuously monitoring equipment performance, companies can detect wear and tear, degradation, and impending failure and plan maintenance at the right time. This reduces unplanned maintenance and downtime.
- Reliability Centered Maintenance (RCM). The RCM approach prioritizes assets according to their risk and criticality. This involves in-depth analysis to determine the best maintenance strategy for each purchase and optimize resource allocation.
- Total productive maintenance (TPM). The TPM approach is holistic and aims to increase the overall effectiveness of equipment (OEE) through engaging all employees. The focus is eliminating defects and downtime while promoting an ownership culture.
- Condition Based Maintenance (CBM). TO DETERMINE EQUIPMENT HEALTH, the CBM process involves monitoring specific requirements or parameters, like vibration, temperature, or lubrication. The maintenance is performed according to the state of an asset. This ensures that resources are utilized efficiently.
- Run-to-Overhaul (RTO). This is a common strategy in the aerospace sector. The equipment is run until it reaches the predetermined threshold. At that point, it's overhauled, or it can be replaced. The strategy aims to balance the requirement for component reliability and the desire to extend the life of the components.
