Implementing Drum‐Buffer‐Rope to Control Manufacturing Lead Time

Drum‐Buffer‐Rope (DBR) is a relatively new approach to inventory and logistics management that effectively supports reduced manufacturing lead‐time. Previous studies have not emphasized this fact nor explained how it is accomplished. This paper describes DBR mechanics, proposes appropriate implementation steps, identifies key ideas, and reports experience with one DBR application. Key ideas identified include the use of input control and excess capacity. Input control is readily implemented within DBR while excess capacity permits DBR flow to be maintained. The reported application demonstrates both the effectiveness of DBR in reducing lead‐time and its vulnerability to misunderstanding.
