Abstract: In order to solve the problem that emergency event scheduling in agricultural machinery steering gear workshop was not timely, the related problems of workshop scheduling were studied, and a workshop scheduling model based on improved immune clonal algorithm was proposed. Firstly, combined with the actual production of agricultural steering gear, the objective function was constructed with the maximal completion time, equipment energy consumption and equipment load. Then, multistrategy population initialization and adaptive mutation operator were used to improve the immune cloning algorithm. Finally, on the basis of analyzing the data of workshop scheduling processing time and energy consumption, taking the fitness of the scheduling model and Gantt chart as indicators, the scheduling effect of the model was validated. The results show that compared with the traditional immune clone algorithm, the improved immune clone algorithm has faster optimization speed and higher optimization accuracy, and can realize fast dynamic scheduling of agricultural machinery steering workshop.
