Problem #3: A manual assembly line is being planned to produce a small consumer appliance. The work elements, element times, and precedence constraints are indicated in the table below. The workers will work for 420 min/shift and must produce 350 units/day. A mechanized conveyor will transport work units through stations. 1. Determine the ideal minimum number of workers (round up) = total time / takt time. 2. Use the largest candidate rule to solve the line balancing problem. 3. For your line balancing solution, compute the balancing efficiency. Work element Time (min) Predecessors 0.4 0.5 0.2 0.6 0.25 0.3 0.37 0.15 0.41 0.2 0.3 0.33 0.4 0.62 THINM70 8 9, 10 11 12, 13
