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 .
