Globalization has had a huge impact on today's manufacturing sector. Manufacturers need to find new and innovative ways to increase efficiency and reduce manufacturing time wastage. Lean/six sigma tools can help companies increase production efficiency and maintain competition. Fertilization in smaller batches can keep production volumes customizable. This leads to frequent changes and crashes. Usually a change is required when one machine produces different products based on the requirements. A large-scale industry can either install several individual production lines to meet demand (usually expensive) or make frequent changes to machinery. Single Minute Exchange Die (SMED) is a system designed to reduce machine changeover time. This paper proposes a model for production scheduling in machine change and discusses its implementation in SMED stages. The paper further explains the feasibility and usefulness of the proposed model. This resulted in a benefit-cost ratio of 8.5 percent.
