摘要
A real-time scheduling algorithm is proposed, that is, to first make a fuzzy classification for the operations of jobs in real-time and then, according to their fuzzy sort, to schedule them with the heuristic. The heuristic is obtained by training a neural network offline with the genetic algorithm. Based on these ideas a real-time scheduler is built with neuro-fuzzy network (NFN). Finally the simulation for the real-time scheduling and the rescheduling are made. The results show that the real-time scheduling algorithm is effective and highly efficient compared to the first in and first out (FIFO) and the Lagrangian relaxation (LR) method.
