为研究与电机智能制造生产线相匹配的高存储密度仓储系统,提出一种由多个回型存储模块连接而成的多模块网格仓储系统,并提出一种最优循环动作方法,使系统内的负载快速地循环移动出库。将系统抽象为节点和边组成的图模型,提出环和循环移动的概念,证明得到一次循环移动所需的最少动作步数。结果表明:在规定的负载配置下,最少可通过2步动作完成一次全库负载的循环移动。最后以一个系统实例为对象,利用所提方法构建最优循环移动,实现系统全负载的快速循环移动与拣选。研究结果可为多模块网格仓储系统的性能分析和设计优化提供理论依据。

[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.
