AB  - Efficient warehouse management is critical for modern supply chain systems, particularly in the era of e-commerce and automation. The Multi-Picker Robot Routing Problem (MPRRP) presents a complex challenge involving the optimization of routes for multiple robots assigned to retrieve items from distinct locations within a warehouse. This study introduces optimized metaheuristic strategies to address MPRRP, with the aim of minimizing travel distances, energy consumption, and order fulfillment time while ensuring operational efficiency. Advanced algorithms, including an enhanced Particle Swarm Optimization (PSO-MPRRP) and a tailored Genetic Algorithm (GA-MPRRP), are specifically designed with customized evolutionary operators to effectively solve the MPRRP. Comparative experiments are conducted to evaluate the proposed strategies against benchmark approaches, demonstrating significant improvements in solution quality and computational efficiency. The findings contribute to the development of intelligent, scalable, and environmentally friendly warehouse systems, paving the way for future advances in robotics and automated logistics management.
