Question: Total work content for a product assembled on a manual production line is 33.0 min. Pro-&elfin rate of the line mast he 47 units/hr. work units are attached to a moving conveyor whose speed = 7.5 ft/min. Repositioning time per worker is 6 sec, and uptime efficiency of the line is 94%. Because of imperfect line balancing, the number of workers needed on the line mast he four more workers than the number required for perfect balance. Assume the manning level = 1.6.
(a) How many workers are required on the line?
(b) How many workstations are on the line?
(c) What is the balance efficiency for this line?
(d) If the work-stations are arranged in a line, and the length of each station is 11 ft, what is the tolerance time in each station?
(e) What is the elapsed time a work unit spends on the line?
