Suppose SureStep could begin a machinery upgrade and training program to increase its worker productivity. This program would result in the following values of labor hours per pair of shoes over the next four months: 4, 3.9, 3.8, and 3.8. How much would this new program be worth to SureStep, at least for this four-month planning horizon with no backlogging? How might you evaluate the program’s worth beyond the next four months?
Answer to relevant QuestionsIn the current no-backlogging problem, SureStep doesn’t hire any workers, and it uses almost no overtime. This is evidently because of low demand. Change the demands to 6000, 8000, 5000, and 3000, and rerun Solver. Is ...We claimed that our model for Barney-Jones is generalizable.
