Detailed production schedule for a resource that sets the pace for the entire system; must reconcile the customer requirements with system constraint(s)

• A. EOQ
• B. Drum schedule
• C. Distribution center
• D. Distribution warehouse

Answer: (B)

The main idea is pacing the entire system around the bottleneck. In Theory of Constraints, the resource that limits throughput sets the pace, and the drum schedule is the mechanism that releases work into the system at that same rate. By aligning downstream and upstream activities to the bottleneck’s capacity, you reconcile customer requirements with system constraints: you produce enough to meet demand without overwhelming the bottleneck, keeping throughput steady and reducing excess work in process. The drum helps ensure the bottleneck is always fed just enough to stay busy, and buffers before the bottleneck absorb variability so due dates are more reliably met. The rope ties the release of new work to the bottleneck’s schedule, while the buffer protects the constraint from disruptions. This approach is distinct from EOQ, which is about inventory lot sizing, or from facilities like distribution centers or warehouses, which are places rather than pacing mechanisms.
