An eight-station assembly machine has an ideal cycle time of 6 sec. The fraction defect rate at each of the 8 stations is q = 0.015 and a defect always jams the affected station. When a breakdown occurs, it takes 1 minute, on average, for the system to be put back into operation. Determine the production rate for the assembly machine, the yield of good product (final assemblies containing no defective components), and proportion uptime of the system.
