Which term refers to the production scheduling approach that enables mixed-model production across a single day?

• A. Materials Handling
• B. Nesting
• C. Mixed-Model Scheduling
• D. Muri

Answer: (C)

Producing different models in one day requires a scheduling approach that keeps the workflow even while switching among models. Mixed-model scheduling is the method that designs the daily or shift sequence so multiple product variants are produced within the same day. It coordinates small, balanced runs of each model, plans changeovers efficiently, and uses a steady takt to meet demand without creating bottlenecks or idle time. This approach aligns with the idea of leveling production across models to maintain a smooth, flexible flow, even when demand shifts between products.

Other terms describe different ideas. Materials handling is about moving and storing materials rather than how to sequence production by model. Nesting is typically about optimizing material usage or layout, not about scheduling multiple models in a single day. Muri refers to overburden or strain on people or equipment, a waste concept, not a scheduling method. So the concept that enables mixed-model production across a single day is mixed-model scheduling.
