Question: A moving belt line is used for a product whose work content = 20 min. Production rate -= 48 units/hr. Assume that the proportion uptime E = 0.96. The length of each station = 5 ft and manning level = 111.The beh speed can be set at any value between 1.0 and 6.0 ft/min. It is expected that the balance delay will be about 0.07 or slightly higher. Time lost for repositioning each cycle is 3 sec.
(a) Determine the number of stations needed on the line.
(b) What would be an appropriate belt speed, spacing between parts, and tolerance time for this line?
