    摘要:

    针对多模块网格存储系统中的多分拣点货物排列问题,提出一种解耦的分散式控制方法,将问题解耦为各存储模块的独立调度和模块之间的协调调度。模块内采用循环移动方式进行独立调度,模块间通过交换需求和模块状态控制协调过程,在不同参数条件下进行了仿真实验,并与集中式控制方法进行了对比仿真。结果表明:分散式控制方法能在各种工况下稳定有效地求解,且相比集中式控制方法的结果更优,求解时间更短,验证了所提方法的有效性和通用性。

    Abstract:

    To solve the cargo arrangement problem of multiple picking stations in multi-module grid-based storage system, a decoupled decentralized control method is proposed, which decouples the problem into independent scheduling of each module and cooperative scheduling between modules. The cycle movement method is used for independent scheduling within the module, and the cooperative scheduling is realized by exchange requirements and module states. Simulation is carried out under different parameters, and a comparative simulation with centralized control method is carried. The results show that the decentralized control method can get solutions stably and effectively under various conditions, and can get better solutions and shorter computing time than the centralized control method. The effectiveness and universality of the proposed method are verified.
