Generating, more costs on labor and initial costs for training. 2nd recommendation Machine 3 should be replaced entirely since it generates the most defects among all the machines. The assumption of replacing machine 3 is that all the defects generated by machine 3 will be down to 0 % Winder 3 142 x 0 = 0 Number of original defects less rework 261 – 142 = 119 Percentage difference after rework 54.41% over 45.59% remaining defects This would mean buying a new machine to replace machine 3 3rd recommendation Machine 1, 2 and 3 will undergo punitive maintenance since all the defects have been accounted for, for each machine. The assumption is that 65% of defects for each machine will go down. With a margin of 35% defects remaining. Winder 1, 2 and 3 261 x 65%= 170 Number of original defects less rework 261 – 170 = 91 Percentage difference after rework 65.13% over 34.87% remaining defects This would mean we will halt production to remedy the problems with the machines to reduce the defects generated by each machine Best SolutionThe best recommendation is the 1st one.
