During every 8 hours of scheduled work, Abe takes 45 minutes of break. He must perform 20 minutes of maintenance on each machine (separately) during every 8 hours of scheduled work. Abe is unable process work while he is performing maintenance. Abe’s company is making some changes to the maintenance schedule. The changes will result in a new weekly capacity of 6000 minutes when Abe is scheduled for a 40-hour work week. If efficiency remains at 90%, what is the new workstation utilization?
