A manual assembly line must be designed for a product with annual demand le 100.000 units. The line will operate 50 wk/yr, 5 shifts/wit, and 7.5 hr/shift. Work units will be attached to a continuously moving conveyor. Work content time = 42.0 min. Assume line efficiency E = 0.97, balancing efficiency Eb = 0.92, and repositioning time Tr = 6 sec. Determine: (a) hourly production rate to meet demand and (b) number of workers required.
