Abstract:
n order to study the storage system with high storage density for the intelligent manufacturing line of motor, a multi-module grid-based storage system which is composed of multiple storage modules is put forward. An optimal cyclic moving method is proposed to make the load in the system move and be picked quickly. The storage system is abstracted as a graph model composed of nodes and edges and the concepts of ring and circular movement are proposed. The minimum number of action steps required for a cyclic movement is proved. The results show that a cyclic movement of all loads in the system can be completed within a minimum of 2 steps. Finally, taking a system instance as the object, the proposed method is used to construct the optimal circular movement and realize the fast cyclic moving and picking of all loads in the system. A theoretical basis for the performance analysis and design optimization of multi-module grid-based storage systems is provided.
