Improving Manufacturing Supply Chain by Integrating SMED and Production Scheduling

Globalization has led to a significant effect on today’s manufacturing sector. Manufacturers need find new and innovative ways increase efficiency reduce waste in the supply chain. Lean/six sigma tools can help companies production stay competition. Manufacturing smaller batches keep chain lean customizable. This leads frequent changeovers downtime. A changeover is usually required when single machine produces different products based requirement. large-scale industry either install multiple individual lines cater demand (usually expensive) or make machinery changes. Single Minute Exchange Die (SMED) system designed for reducing time machines. It reduces taken complete activities eliminates non-essential throughout changeover. Scheduling an operating procedure within SMED such case challenge. Project scheduling model with workforce constraints be used create set of heuristics provide us optimized list tasks. The paper proposes design heuristic allocate tasks operators get least amount operator idle downtime costs. further illustrates benefit study its integration existing methodology. results benefit-to-cost ratio 7.5% compared that stages 4 5 SMED, which 1.2%.
