1 – Corrective or reactive maintenance
The corrective maintenance strategy should always be reserved for equipment that is not essential for production and that has a low replacement cost.
Applying a corrective maintenance strategy carries the highest costs, as this kind of maintenance can’t be scheduled, requires excessive staffing in order to handle high incident volumes, necessitates expensive on-call staffing, and causes stress for maintenance personnel and dissatisfaction for the client, resident, or user.
2 – Preventive maintenance
Preventive maintenance is the most commonly used strategy. Inspections, tests, and maintenance on technical equipment are scheduled at regular intervals. While Twimm’s CMMS tool makes preventive maintenance tasks easy to schedule, carry out, and monitor, the time and labor involved constitute a substantial expense. In most cases, service calls are triggered by theoretical and arbitrary criteria and decisions, in terms of the actions taken and the frequency of visits. As a result, it is still possible to reduce the cost involved in this maintenance approach. Choosing the best strategy is a major driver of savings for the property manager, as well as a way for maintenance service providers to stand out.
Twimm assists in this optimization by providing the indicators you need to measure the efficiency of your operations. For example, an annual review of the efficiency of your preventive maintenance schedule will help reduce time spent on maintaining equipment in operational condition.
However, preventive maintenance is not as efficient as predictive maintenance.
3 – Predictive maintenance
Predictive maintenance allows you to foresee the need to replace or service an item before it causes any damage. The goal of predictive maintenance is to increase facilities’ lifespan and reliability. It also produces a considerable reduction in technical teams’ workload and facilities’ downtime. As you can see, predictive maintenance allows you to optimize your maintenance budget.
The only drawback is that implementing a predictive maintenance strategy can be complex, as it requires sensors and a good deal of data processing. We at Twimm can guide you through those challenges.
4 – Reliability-centered maintenance
The concept of reliability-centered maintenance (RCM) comes to us from the aviation industry, where maintenance is clearly a vital concern. In this strategy, priority is given to critical elements that, in the event of malfunction, can lead to a technical facility’s systemic failure. Based on the priority levels assigned to equipment items, RCM guides the selection of the most suitable maintenance strategy (corrective, preventive, or predictive).
When we apply a reliability-centered maintenance strategy, we also come to understand that the age of a piece of equipment is not, in most cases, a decisive factor in the likelihood of a breakdown. This strategy is the preserve of experienced teams with significant means at their disposal. It signals a high degree of maturity. When implemented appropriately, this is the most suitable strategy for heavy industry.
