A plant runs in two shifts, one shift of 8 hours and during each shift there is 2 hours of planned downtime. If the machine is stopped each day an average- of 110 minutes for setups and 75 minutes for breakdowns and repairs. Determine the availability of machines. Also suppose the average daily throughput of the machine is observed to be 830 units, and the actual cycle time is observed to be 0.6 min/part. Determine the rate efficiency and performance efficiency of machines (Assume speed efficiency = 0.83).
