摘要

摘要:本文研究了机械化仓库大通道拣货路线优化问题。对于不同的拾取密度，比较了三种流行的启发式策略(返回、遍历和z拾取)的效率。提出了一种改进的Z-pick策略，具有灵活的管柱长度，以提高其效率并适应叉车的移动。仿真结果表明，在10 - 15%的拣货密度范围内，三种策略之间没有显著差异。遍历策略在选择密度低于无差异区域时表现更好，而返回策略在更高选择密度时表现优于其他策略。然而，z锥提供了一种可行的通用选择，适用于所有测试过的锥密度。

A Comparison of Three Popular Routing Policies for Lift-truck Order Picking

Abstract:This study addresses order-picking routing optimization in a wide aisle of a mechanized warehouse. Efficiencies of the three popular heuristic policies (return, traversal, and Z-pick) are compared for different pick densities. A modified Z-pick policy with a flexible string length is proposed to increase its efficiency and accommodate lift-truck movement. The simulation-based results show that all three policies are not significantly different in the pick density region of 10–15 percent. The traversal policy performs better at pick densities below the region of indifference, while the return policy outperforms the others at higher pick densities. However, the Z-pick provides a viable universal alternative across all tested pick densities.
