Balance the assembly line in Exhibit 8.12 for (a) a shift output of 60 pieces and (b) a shift output of 40 pieces. Assume an eight-hour shift, and use the rule, choose the assignable task with the longest processing time. Compute the line efficiency for each case. For an output of 60 pieces/shift, cycle time = 8(60)/60 = 8 minutes/unit. You need to go over the cycle time calculation carefully. Work station Tasks Total Time Idle Time 1 2 3 4 5 6 7 Total
