Reactive maintenance, also known as corrective maintenance or fault maintenance;. Preventive maintenance, which is the periodic maintenance that is performed. Since it does not require complicated or costly implementation requirements, preventive maintenance is often the preferred option for all companies that want to reduce the long-term costs of their maintenance operations and remain competitive in the market. The opposite of planned maintenance is unplanned maintenance, which has not been properly prepared and is planned according to plan as the work is being done.
It's not uncommon for emergency maintenance costs to cost twice what a preventive maintenance strategy costs, since the response is very urgent and the nature of the maintenance is often extensive. Whereas preventive maintenance is maintenance that has been identified to prevent or mitigate a mode of failure. An inevitable aspect of running a company is the regular maintenance of its assets, equipment and properties. Risk-based maintenance is essentially preventive maintenance in which the frequency and scope of maintenance activities are continuously optimized based on the results of tests or inspections and a comprehensive risk assessment.
This means you need to have a way to track available spare parts, quickly communicate changes in task priority, stay on top of pending maintenance activities, and keep track of essential maintenance KPIs, such as failure metrics. Predictive maintenance is actually a type of preventive maintenance, since both allow maintenance to be performed before the fault occurs. Risk-based maintenance (RBM) consists of using a risk assessment methodology to assign scarce maintenance resources to assets that pose the greatest risk in the event of a failure (taking into account that risk = probability x consequence). Because they are not based on the actual condition of the equipment, preventive maintenance plans can sometimes be inefficient and result in unnecessary maintenance (including replacement of parts) that costs time and money.
However, the problem is that most people think of traditional time-based maintenance when they talk about preventive maintenance. Another common problem with emergency maintenance is that parts and services often arrive faster and, to do so, higher costs are incurred. Planning refers to the process of planning and scheduling maintenance, so maintenance planning consists of preparing the maintenance work so that it is ready to be executed. When most people talk about preventive maintenance, they're actually referring to time-based maintenance, that is, a repair or replacement at a fixed interval, regardless of the condition of the equipment.
