In a typical five-day period, the planning department programs a particular machine to work for 80 hours – its loading time. Changeovers and set-ups take an average of 4 hours and breakdown failures average 3 hours every five days. The time when the machine cannot work because it is waiting for material to be delivered from other parts of the process is 2 hour on average and during the period when the machine is running, it averages 98 per cent of its rated speed. Subsequently 4 per cent of the parts processed by the machine are found to be defective in some way. Based on the information given above, calculate the Overall Equipment Effectiveness.
