Abstract

The present study aims to analyze the main reliability measures for packing equipment used in the production process of corn chips. The Anderson-Darling test was used to evaluate the best distribution of the data collected, showing the lognormal distribution as the best model for the data. We used the Minitab v.17 software for the probability functions of some statistical models. The results showed an MTTF indicator at 2.5 days and R(t)=0.47. Furthermore, the packaging equipment depends on maintenance actions having only a 47% chance of not failing when in operation.
