Abstract: Different from traditional single-export and single-check stations in small warehouses, large warehouses are often equipped with multiple check stations and multiple outlets to improve the efficiency of warehouse picking and leaving. This article proposes a dynamic adjustment algorithm based on replacing review station to solve the difficulty in traversal search caused by the uncertainty of the start and end points in the scenario of multiple review stations. On this basis, dynamical adjustment strategies with path optimization and reasonable allocation of multi-task orders are provided to meet the requirement of picking operations in large-scale and complex scenarios. Compared with the example of Jingdong logistics, it is shown that the dynamic adjustment algorithm based on the replacement of review station proposed in this paper is more efficient, with shorter picking path, less picking time and more accurate warehouse picking under the same conditions.
