A five process goes through the sequence of machines A-B-C-D-E. Each machine discards 5% scrap. The current demand is 5000 good units per day. (a) Determine the number of units per day (b) The standard time per part processed at each machine is 3 minutes. The corresponding machine requires a 20-minute set-up every day. Assuming one daily 8-hour shift, and a machine availability factor equal to 0.85, determine the fractional number of machines required.
