A flow line mass production operation consists of eight manual workstations. Work units are moved synchronously and automatically between stations, with a transfer time of 15 sec. The manual processing operations performed at the eight stations take 40 sec, 52 sec, 43 sec, 48 sec, 30 sec, 57 sec, 53 sec, and 49 sec, respectively. Determine (a) cycle time for the line, (b) time to process one work unit through the eight workstations, (c) average production rate, and (d) time to produce 10,000 units.
