| Summary: | 碩士 === 國立交通大學 === 管理學院碩士在職專班工業工程與管理組 === 93 === Manufacturing Companies often face some problems , such as low orders’ hit ratio , too many Works-In- Process (WIP) , high machine down times and quality issues . They always think problems from the complexity of manufacturing processes and frequent abnormal events. Coming out the action items are to stable the machines’ running and products’ quality . But Drum-Buffer-Rope (DBR) provide another way to manage abnormal events , by three steps （1）Identify the system’s constraint（2）Decide how to Exploit the system’s constraint（3） Subordinate everything else to the above decision . Reaching max throughput and min WIP , managing the effect of abnormal events , and smoothly manufacturing.
The research is an application of one array fab of a TFT-LCD company in our country , manufacturing below 17 inches’ panels . In July 2004 they try to direct the solution of DBR . In practice they transfer the three steps of DBR to seven operations（1）Decide the shipping plan（2）Setup system parameters（3）Decide the bottleneck plan（4）Form the input plan（5）The dispatching in the bottleneck（6）The dispatching in none-bottleneck （7）Buffer management . By the practice the result shows that DBR could reach higher orders’ hit ratio , higher throughput and lower WIP . And it solves the conflict of keeping machine efficiency and hitting the orders . Let the operations in the manufacturing more consistent .
