A seven-station transfer line has been observed over a 40-hour period. The process times at each station are as follows: station 1, 0.80 min; station 2, 1.10 min; station 3, 1.15 min; station 4, 0.95 min; station 5, 1.06 min; station 6, 0.92 min; and station 7, 0.80 min. The transfer time between stations = 6 sec. The number of downtime occurrences = 110, and hours of downtime = 14.5 hr. Determine
(a) the number of parts produced during the week,
(b) the average actual production rate in parts/hr, and
(c) the line efficiency.
(d) If the balancing efficiency were computed for this line, what would its value be?
