| 针对自动化立体仓库库区货位分配存在的出入库速度慢、货架稳定性差以及货品相关性低的问题，课题组提出了一种优化方法。首先，进行数学模型的搭建，为各目标函数分配权重，对比较重要的目标函数进行人为增量，提升目标函数的计算值敏感程度，达到自我分辨的目的；其次，通过引入非线性动态移动参数，提出一种改进的海鸥算法，并采用6种基准测试函数来验证改进算法的寻优能力。结果表明改进后的算法在精度以及寻优速度上都优于原始算法。该模型能够提升货物的出入库速度和货品相关性，保证货架稳定性，可有效提升立体仓库利用率。 |

| An optimization method was proposed to solve the problems such as the low speed of loading and unloading, the low stability of shelves and the low correlation of goods. First of all, the mathematical model was built, weights were assigned to each objective function, and artificial increment was made to the more important objective function to improve the sensitivity of the calculated value of the objective function, so as to achieve the purpose of self discrimination. Secondly, by introducing nonlinear dynamic motion parameters, an improved seagull algorithm was proposed, and six kinds of benchmark test functions were used to verify the optimization ability of the improved algorithm. The results show that the improved algorithm is superior to the original algorithm in result accuracy and optimization speed. This model can improve the speed of goods in and out of storage and the correlation of goods, ensure the stability of shelves, and effectively improve the utilization rate of three dimensional warehouse. |
