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%
