Balance the assembly line shown below for (a) a shift output of 50 pleces and (b) a shift output of 45 pieces. Assume an six-hour shift, and use the rule: choose the assignable task with the longest processing time. Compute the line efficiency for each case. Time minutes a. Fill in the table below for a shift output of 60 pieces. Break ties by choosing the lowest task number. If your answer is zero, enter "O". Round your answers to the nearest whole number.
