The breakdowns code represents each recorded breakdown. If the same code appears on more than one day, it is because the repair did not take place or was not finished on the preceeding day. The machine total set up time is 187 minutes, and in those 15 days the machine produced a total of 6280 products. The company works 24/7. The theoretical cycle time is 2 minutes per part.
