Abstract: Considering the situation that the stacking machine performing the operation in the automated warehouse, the optimization problem of the selection path of the stacking machine in the case of semi-tray out of the automated warehouse is put forward, and a model is built. Concerning the features of the problem, a discrete fireworks algorithm is used to solve the model. The algorithm uses explosion operators and mutation operators in the iterative optimization process to implement the algorithm's global search and local search. The algorithm applies the elite selection strategy and similar roulette strategy to improve the convergence effect. Taking the automated warehouse system of a tobacco logistics company as an example, the discrete fireworks algorithm is compared with other algorithms. The results of discrete fireworks algorithm is compared with those of other algorithms, and it is verified that the algorithm has a superior solution.
