【 摘 要 】

Maintenance plays an important role in the pursuit of competitive advantages by companies. Equipment reliability analysis is in this regard essential in defining the most appropriate maintenance strategies. This study applies reliability analysis to evaluate the coherence of the current equipment maintenance strategy employed in a Brazilian food industry company in São Paulo state. The research method used was statistical modeling applied to the time to repair (TTR) and time between failures (TBF) for six packaging machines on one of the company's production lines. These times were modeled by Log-normal and Weibull probability distributions. The results indicate that the current preventive maintenance strategy adopted for the equipment is not appropriate, as the equipment is in the infant mortality phase in the cycle of its working life, which indicates a corrective maintenance strategy be used to identify and eliminate the origin faults.
