Selection of Preventive Maintenance Methods and Strategies
Preventive maintenance - Methods and technologies

The previous sections presented the principles and technologies applicable to maintenance, without addressing selection criteria or the frequency of maintenance interventions. This section focuses on the elements necessary for developing a preventive maintenance program for complex industrial equipment. Analyzing operational experience (REX) is essential, as it allows for determining the probability distributions of equipment failure rates. Figure 32 illustrates the most common patterns of these rates. For example, curve E applies to electronic equipment with a constant failure rate: a failure can occur...
