Which principle emphasizes that actual customer demand influences production scheduling?

The principle that emphasizes actual customer demand influencing production scheduling is the Pull System. This approach is designed to produce goods based on actual demand rather than forecasting or speculation. In a Pull System, production is triggered by customer orders, which means that no products are made unless there is a specific requirement from the customer. This method helps to minimize excess inventory, reduce waste, and align production closely with real-time demand.

In contrast, Just-In-Time focuses on minimizing inventory and improving efficiency but does not explicitly highlight the role of customer demand in scheduling production. Lean Manufacturing aims to streamline processes and eliminate waste in a broad sense, which is important but does not solely focus on demand-driven production. Aggressive Forecasting, on the other hand, relies on predictions about demand rather than responding to actual customer orders, which diverges from the core principle of a Pull System. Thus, the correct choice reflects the philosophy of allowing actual demand to dictate production rather than relying on forecasts or push strategies.
