Final answer:
Just-in-time systems are systems in which supplies and assemblies are "pulled" through the system when and where they are needed.
Step-by-step explanation:
Just-in-time systems c. Systems in which supplies and assemblies are "pulled" through the system when and where they are needed. This approach aims to minimize inventory costs and increase efficiency by closely aligning production with demand. Rather than stockpiling large quantities of parts or products, supplies are delivered in small quantities as they are needed. For example, in the automotive industry, car manufacturers use just-in-time systems to have parts delivered to assembly plants right when they are needed in the production process. This helps to reduce waste, improve quality control, and optimize overall operations.
