Formula: Throughput = Min(Demand Rate, Constraint Rate)

Introduction to Drum Buffer Rope Throughput Calculator

The Drum Buffer Rope (DBR) throughput calculation is a key component in the Theory of Constraints (TOC). This formula is used within the DBR scheduling system to determine the rate at which a system should produce to meet demand without exceeding the system's constraint, often called the 'drum'. The 'buffer' protects the drum, ensuring the process flow is not interrupted.

Parameter usage:

Output:

Data validation

The demand and constraint rates must be greater than zero, and the constraint rate must not exceed demand rate.

Summary

This calculation is used to synchronize the production rate with the market demand, considering the most limiting factor in the production chain.
