The Demand Time Fence (DTF) refers to what aspect of scheduling?

The Demand Time Fence (DTF) is an essential concept in scheduling that specifically aims to protect the integrity of existing customer orders. Within this time frame, changes to production schedules or order allocations are typically not allowed, as it helps ensure that commitments made to customers are honored. This safeguarding of existing orders is crucial for maintaining customer satisfaction and trust, as it minimizes the risk of disruptions that could arise from last-minute changes.

Understanding the Demand Time Fence also highlights the importance of balancing operational flexibility with the need for stability in fulfilling customer demands. The DTF essentially creates a boundary that defines a safe zone for customer orders, ensuring that all stakeholders involved in the supply chain management can rely on the set commitments without facing unexpected changes.
