A Novel Hybrid Algorithm for Order Picking Optimization in Automated Warehouse

Automated storage and retrieval system (AS/RS) is widely used in the logistics industry. To improve the efficiency of the AS/RS, this paper investigates the order picking problem. An optimization model is constructed for the problem, which aims to minimize the time of the retrieval and storage operation. By combining free search(FS) and amendment circle algorithm, a novel algorithm is developed to solve the model. Simulation results demonstrate the approach has quick and good search ability, satisfying the demands of the large scale problem.
