Analysis of maintenance policies supported by simulation in a flexible manufacturing cell

ABSTRACT The purpose of this article is to analyze three maintenance policies in a flexible manufacturing cell from a mechanical manufacturing company. The policies were opportunistic maintenance, in which all the machines are repaired whenever the cell stops, corrective maintenance, in which only t...

The policies were opportunistic maintenance, in which all the machines are repaired whenever the cell stops, corrective maintenance, in which only the failed machines are repaired whenever the cell stops, and partial corrective maintenance, in which only the failed subsystem is repaired whenever the cell stops.

The evaluation of the policies relied on the number of repairs and the resulting MTBF of the cell. The simulation relied on twenty replications of the three policies to ground the analysis.
