500 garments per shipment. Although the number of garments changes‚ the total change-over costs would stay the same‚ because no additional retooling of the machine would be necessary. The whole change-over process takes 3 hours regarding if the number of garments is 200‚ 500 or 800. Furthermore‚ let’s strictly theoretically assume that the company is able to achieve some extra capacity and one batch is now composed of 150 garments instead of 100 garments. Still‚ although the total number of garments
