| description | The invention discloses a flexible job shop scheduling optimization method based on a Petri network and brainstorm. The method comprises the following steps: step 1, collecting production data of a flexible intelligent manufacturing production line workshop; 2, constructing a time delay Petri net model of the flexible intelligent manufacturing production line workshop according to the collected production data; step 3, determining description of a flexible intelligent manufacturing workshop production line scheduling problem, considering constraint conditions during actual processing production, and establishing a target function of a flexible production scheduling problem; and step 4, optimizing the objective function by using a time delay Petri network model and a scheduling algorithm of a discussion mechanism BSO, and obtaining an optimal solution of the objective function, namely completing optimization of the scheduling problem of the flexible intelligent scheduling workshop. According to the method, the |
