Balance the assembly line shown below for (a) a shift output of 30 pieces and (b) a shift output of 24 pieces. Assume an 6-hour shift, and use the rule: choose the assignable task with the longest processing time. Compute the line efficiency for each case. a. Fill in the table below for a shift output of 30 pieces. Break ties by choosing the lowest task number. If your answer is zero, enter "0". Round your answers to the nearest whole number. a. Fill in the table below for a shift output of 30 pieces. Break ties by choosing the lowest task number. If your answer is zero, enter "0". Round your answers to the nearest whole number. What is the assembly-line efficiency? Round your answer to one decimal place. % b. Fill in the table below for a shift output of 24 pieces. Break ties by choosing the lowest task number. If your answer is zero, enter "0". Round your answers to the nearest whole number. What is the assembly-line efficiency? Round your answer to one decimal place. % b. Fill in the table below for a shift output of 24 pieces. Break ties by choosing the lowest task number. If your answer is zero, enter "0". Round your answers to the nearest whole number.
