The correct answer is A. in-time production.
In-time production, also known as just-in-time production, is a production method in which components are manufactured and delivered only as they are needed for assembly. This system is designed to reduce inventory costs and improve efficiency.
Materials requirement planning (MRP) is a production planning and inventory control system used to manage manufacturing processes. MRP systems use bill of materials (BOM) data, inventory data, and production schedules to calculate the exact quantities of materials and components that are needed to manufacture a product.
On-time production is a production method in which products are manufactured and delivered on time, according to customer demand. This system is designed to improve customer satisfaction and reduce costs associated with late deliveries.
Pull strategy of production is a production method in which production is triggered by customer demand. This system is designed to reduce inventory costs and improve efficiency.
In a push-through system, goods are manufactured for finished inventory solely, on basis of forecasted demand. This system is not as efficient as in-time production, as it can lead to excess inventory and production costs.
