Abstract:This research looks at the improvement of the capacity of one of the three MDF sawing machines at Nelson Pine Industries Ltd, to reduce overtime of the sawing machines. The overall equipment effectiveness is used as a framework for improvements. By doing a Pareto analysis on the downtime causes of one year, the top ten downtime causes are found. These downtime causes are discussed with Nelson Pine. One of the causes is solved during this research, which should reduce the downtime by at least 6%. An additional result is that the solution should increase the quality of the MDF. To increase the speed of the sawing machine, a simulation study is done. By implementing the results of the simulation study, the throughput should be increased by almost 10%. Since this is amplified by a higher uptime, this research leads to a direct increase in overall equipment effectiveness of the sawing machine of about 16%. Next to that, by implementing a system which automatically records the downtime and the related downtime causes, this research should facilitate with a culture of continuous improvements.
