Advances, Systems and Applications
Scheduling Method | Strength and Advantages | Disadvantages or Limitations |
---|---|---|
Monte Carlo Simulation Method | High precision to get the best schedule. The Monte Carlo method reduces the memory requirements of the fixed short scheduling period, resulting in high system throughput. | High simulation work with exhaustive searches for optimization. This method does not make the adapt to sudden changes in workload. Longer planning horizons degrade performance. |
Blind Pick Scheduling Method | With moderate overhead, this method applies a reduced search space and can somewhat adapt to rapid workload fluctuations. | It has moderate accuracy because it has less overhead. With a bad selection set, the performance drops in Monte Carlo. |
Ordinal Optimization (Proposed) Method | With very little overhead, OO can adapt to fast workload fluctuations and run suboptimal schedules with high multitasking throughput and reduced memory footprint. | The suboptimal schedule generated at each period may not be as optimal as the schedule generated by the Monte Carlo method. A high noise level can degrade the schedule generated by OO. |
