Characteristics  Of  Computer  Controlled Scheduling (Ccs)

To control the manufacturing system in an effectual way, the system is normally composed in a task-based hierarchy. The hierarchy contains five levels and is demonstrated in figure. At The lowest level of the system, the system contains physical machining equipment. Workstation equipment gives integration and interface functions for the equipment and it that resides just above the process level.

This must be noted in various existing models that several of the above assumptions are partially relaxed. For the illustration, the literature on parallel machine scheduling studies the work centers which comprise m processors that may be capable to process m jobs simultaneously.

Within computer controlled Scheduling models, all the equipments should explicitly identify under the supervisory computer control. This comprises machines, auxiliary stations, material handlers, and restricted capacity storage space. The individuality of the CCS problem originates mostly from the following figure as given below:

  • Usual resource models;
  • Part contact states;
  • Deadlocking;
  • Dynamic machine routing;
