Abstract
This paper studies the application of the A* algorithm to optimize the order-picking routes warehouse operation. With the growth of the logistics and e-commerce sectors, the demands for efficiency and speed in warehouse management are becoming increasingly higher. However, identifying the optimal order-picking routes in warehouse remains a significant challenge. By applying the A* algorithm, this research has found a solution to optimize the picking routes, reducing order processing time, operational costs, and enhancing warehouse performance. The results show that this application has improved the order-picking process, minimized congestion, and increased operational efficiency.
