In manufacturing, it is always vital to keep costs down and for that reason we need to focus on the three cost drivers that can be controlled. These are lot size, set-up and changeover times, as well as machine costs. It is important to look at how lot sizes affect the costs of parts. Set-up changes and changeover times are also an important cost driver as these can keep machines running and... Read More
