There are different lines for different products running along the entire length of the manufacturing floor. Raw materials and parts go in one end and the product comes out at the other end. Most of the cabinets are custom built, so employees must be flexible. Schematics must be followed, parts reordered and quality rechecked at each stage along the line. As in any manufacturing plant, there is a great deal of math used on a daily basis.
Control charts deal with averages, plotting points, and interpreting graphs.
They are used to determine changes to implement based on dips and peaks on the graph. Nesting requires calculating area of rectangular regions and maximizing the area of materials that can be utilized for manufacturing parts.
