三维紧致化存储系统中出入口位置的优化研究

Optimization of I/O Point in 3D Compact Storage System

目的解决三维紧凑型存储系统的设计问题,寻求系统出入口的最佳位置。方法建立数学模型,并优化求解,研究自动化仓储系统出入口位置的设计问题。结果在双命令存储模式下,当三维紧致化仓储系统的系统出入口位置在货架底端1/2位置时,双命令行程期望时间最少。结论通过假设出入口的位置,列出共计24种双命令下存取货物的期望时间模型,并进行了求导分析,发现在双命令存储模式下系统出入口最优点即为货架底端中点处。

The work aims to solve the design problem of the 3 D compact storage system and seek the best position to enter and exit the system. Mathematical models were established and the solutions were optimized to study the design issues of the entrance and exit position of the automatic storage system. In the dual-command storage mode, the expected time of dual-command travel was the least when the entrance and exit position of the 3 D compact storage system was at the midpoint of the bottom of the shelf. Based on the assumptions on the entrance and exit position, a total of 24 expected time models for delivering and accessing the goods under dual commands are listed, and the derivation and analysis are conducted to find out that the optimal input/output point of the system in the dual-command storage mode is the midpoint of the bottom of the shelf.
