Abstract: In order to overcome the problems such as low efficiency of flexible production line and delay of production, this paper proposes a scheduling method of green flexible production line based on task priority. The mathematical model of green flexible production line scheduling is established with the constraints of non-interruptibility and machine uniqueness. The dynamic algorithm of task priority based on the number value of remaining operations is applied to the model to determine the priority distribution order. Through ant colony optimisation algorithm to determine the processing path, through the expression of pheromone and the establishment of ant colony solution to achieve green flexible production line scheduling. The experimental results show that the research method can effectively schedule the green flexible production line, and the machine utilisation rate is more than 90% of the processing level, which effectively reduces the production delay of the workpiece.
