Research on Job Scheduling Problems with DMS for Cell Controller Based Bogie
For tackling job scheduling problems encountered with discrete manufacturing system for 380km/h motor bogie, Object-oriented Petri Net based Job-Shop Cell Controller System (OPNCC) was brought forward identifying categories of all objects within cell control model, describing relationship between categories, analyzing and recognizing cell control logic through the dynamic behavior of physical objects and introducing control decision and strategy into the control logic of as designed OPN model, thereby constituting a complete object-oriented cell control model. With improved genetic algorithm, it can offer dynamic optimization to balanced production of multiple work pieces on several machine tools so that the machine tools can be utilized to a maximum extent.
