One is traditional capacity balance design, and the other is DBR（Drum-Buffer-Rope, DBR）ramp-up protective capacity design. A good manufacturing system is enable to reduce production cycle time and raises the reliability of due day. In order to reach the objectives, manufacturing system must overcome the effects of various variable events, random fluctuation on production line, and minimum of the production cost as well. In view of the foregoing, traditional production system pursues capacity balance and places work-in-process (WIP) inventory in front of every machines to protect overall line, which will lead to production cycle time raise and lower the reliability of due day. Meanwhile, the DBR production system pursues flow balance and ramp-up capacity to protect overall line, ramp-up capacity investment will change by line bottleneck’s location. In general, ramp-up capacity investment will greater than traditional capacity balance, but it will show good results in lowering WIP, cycle time, and due day. As to the results, how many the benefits will be? In order to answer the benefits, this research builds a simulation production line (DBR and traditional system) with EM-Plant software to simulate and analyze the results of both production line design concepts. It shows that the DBR system gets better results than traditional system as a whole.
