Abstract: In the production process of manufacturing workshops, the recovery of material handling equipment is a crucial aspect of workshop logistics management, often overlooked in practical production and related research. An optimization method for workshop material delivery routing is proposed, comprehensively considering both material delivery demands and the recovery tasks of material handling equipment, with a focus on the material distribution process involving towed automated guided vehicles(AGV) combined with material handling equipmen. Firstly, considering the capacity constraints of towed AGVs for material handling equipment, a material delivery routing planning model is established aiming to minimize AGV assignment costs, path transportation costs, and time penalty costs in the workshop material delivery process. A heuristic two-stage distributed optimization algorithm is designed to solve this model. In the first stage, for static material delivery demands calculated based on the production plan, an improved non-dominated sorting genetic algorithm II is employed to generate a sequence of multi-objective material demand delivery tasks. In the second stage, for material handling equipment recovery tasks dynamically arising during the production process, a quadrant optimization strategy is adopted to insert these tasks into the existing delivery sequence, optimizing overall costs and efficiency. Finally, a digital workshop of an armature manufacturing enterprise is used as a case study to verify the effectiveness and feasibility of the proposed optimization method, providing reference and support for logistics management in manufacturing workshops.
