Abstract |
CertainTeed manufactures roofing shingles at it's Shakopee, MN facility. Two process coating lines, and one assembly line, produce fifteen shingle types in fifteen different colors. The wastes generated by this process were the result of planned and unplanned variations in the continuous production process. Planned variations included changes in color, while felt breaks were common unplanned variations. Five options were identified that could reduce the amount of waste generated: Using a standard procedure for recovering from felt breaks, Creating a process cushion to maintain continuous production in the event of temporary shutdowns, An automated color change process, Manufacture of a new product from waste material, Minor process changes to reduce the frequency of breaks. |
