Development of Decision Support Model for Selecting a Maintenance Plan Using a Fuzzy MCDM Approach: A Theoretical Framework
Table 1
Comparison between equipment maintenance strategies [
10].
| Factor | Corrective | Preventive | Condition Based |
| Concept | Machine to run to failure and repair or replace to occur when damage is apparent | Periodic maintenance, so that any possible damaged parts are replaced | Maintenance based on machine condition |
| Reliable for | Small and noncritical equipment, and if equipment has less probability to fail or system is redundant | Deteriorating and consumable equipment, as well as the ones with higher failure pattern | Critical equipment with random failure patterns |
| Pros | Low cost and staff requirements | Flexibility Increase machine life Reduce failures Cost saving up to 18% in comparison with corrective | Increase machine life Decrease costs Maintain product quality Energy saving Cost saving up to 12% in comparison with preventive |
| Cons | Increase downtime, labor costs, replacement incidents | High labor requirement Unneeded maintenance Damage of sound components | Increase diagnosis costs Increase training costs |
| Usage in industry | 55% | 31% | 12% |
