基于嵌套分区算法的立体仓库货位分配优化

Location allocation and optimization of AS/RS based on nested partitions method

根据小型立体化仓库运营特点,基于顺序单目标优化思想,提出一种新的仓库货位分配策略。将考虑存储能耗、货架稳定性、运行效率的多目标仓库货位优化问题,转化为单目标优化,建立了仓库货位优化数学模型。根据数学模型特点,采用嵌套分区算法进行优化求解。通过算例分析证明该分配策略与优化方法,可有效处理多目标仓库库位优化问题,优化效果显著。

According to the operational characteristics of AS/RS, a new storage location allocation strategy is employed based on the sequential single-objective optimization. The method adopts the single-objective optimization through con- sidering the storage energy consumption, shelves stability and operational efficiency. The mathematic model of storage location optimization is established in which the nested partitions method is applied. The calculation analysis shows that the allocation strategies and optimization can deal with multi-objective storage location optimization and the results are comlaarativelv remarkable.
