Question: Work content time for a product assembled on a manual production line is 45.0 min. Production rate of the line must he 40 units/hr. Work units are attached to a moving conveyor whose speed e 8 ft/min. Repositioning time per worker is 8 sec, uptime efficiency of the line is 93%,and manning level = 125. Because of imperfect line balancing, it is expected that the number of workers needed on the line will be about 10% more than the number required for perfect balance, if the workstations are arranged in a line, and the length of each station is 12 ft.
(a) how long is the entire production line, and
(b) what is the elapsed time a work unit spends on the line?
