摘要: 拣货作业作为在制造企业仓储系统中重要环节,其工作效率直接影响整个仓储系统的运行速度和工作成本。首先基于现有蚁群搜索算法,研究了将原有的二维平面搜索路线空间扩展到三维空间的改进蚁群算法;其次对改进蚁群算法进行仓储三维空间路径优化研究,针对现有仓库货架模型,将蚁群算法中两点间的直线路径转化成水平与垂直的折线路径将概率模型与禁忌表方法加入到改进蚁群算法,避免局部最优解的情况;最后将改进蚁群算法与其他代表性优化算法比较。实例验证结果表明,改进蚁群算法方法能有效地提高在仓储系统三维空间内路径规划的效率与速度。

Abstract: As the important part of manufacturing enterprise storage system,the picking operation directly affects the running speed and working cost of the entire storage system.Based on the existing ant colony search algorithm,the improved ant colony algorithm which had extended the original two-dimensional plane search route space to three-dimensional space was studied.Aiming at the existing warehouse shelves,the improved ant colony algorithm was used to carry out the storage three-dimensional space path optimization research.The model transformed the linear path between two points in the ant colony algorithm into horizontal and vertical polygonal path;then the tabu table idea was introduced into the improved ant colony algorithm to avoid the local optimal solution;the improved ant colony algorithm was compared with other representatives' optimization algorithms.The results showed that the improved ant colony algorithm could effectively improve the efficiency and speed of path planning in three-dimensional space of the warehouse system.
