Optimization Method of AGV System of Express Distribution Center Based on Load Balancing
To address the load imbalance in the road network that occurs during the deployment of automated guided vehicles ( AGV) in express distribution center, a multi-objective hierarchical model that considers load balancing is developed.Firstly, in order to introduce node load cost, the model is pre-processed by using the A* algorithm, which considers the cost of turning.Then, to optimize the delivery port layout, the hybrid genetic algorithm used for solving takes the minimum path cost and maximum load balancing degree as optimization objectives.And by adding node load cost to the improved A*algorithm, the evaluation function value is obtained.Finally, simulation experiments are conducted in a grid graph.The results indicate that the proposed model can optimize the layout of delivery ports in express distribution centers and effectively balance the load on the road network.
