- Abstract:
-
The global optimization algorithm for solving the production scheduling optimization problem of the flexible flow shops often adopts the group evolution algorithm or the mathematical programming algorithm. In the process of scheduling and optimizing new production tasks, these optimization methods need to perform time-consuming iterative optimization calculations again every time. Therefore, an intelligent scheduling optimization method based on deep learning is proposed to solve above problem. Through historical production data training, a sequence-to-sequence (Seq2Seq) deep learning model based on gated recurrent unit (GRU) is used to focus on the correlation between the production task information and process information in the scheduling data and the scheduling results. And further this correlation is used as the input of the model encoder; and the output of the model decoder is the on-line sequence of the workpiece. According to the on-line sequence, effective scheduling results can be quickly given, and the accuracy and speed of optimization can be further improved by introducing an attention mechanism. The results of simulation experiment show that the flexible flow shop scheduling optimization method based on deep learning can quickly obtain better scheduling optimization results.
