备注

基于自动分拣系统的作业原理,研究集中式和分散式自动分拣系统的作业流程、作业步骤和动作组成,剖析各个作业的动作时间,构建两种分拣系统的作业时间模型.根据某轮胎企业的实际数据,利用Matlab软件对两种系统的作业时间进行仿真,对比分析两种系统的分拣效率.调整品规数量进行两种分拣系统的效率仿真,分析品规数量对两种系统分拣效率的影响.结果表明,系统作业效率受品规影响小于集中式系统.

The centralized and decentralized automatic sorting models based on the operating principles of automatic sorting systems are proposed. The detailed studies on the operation processes, operation steps and the compositions of working actions for the two automatic sorting systems are carried out. Through the analysis of every working action time, the operation time models for two sorting systems are developed. Matlab is chosen to simulate the operation time for the two systems based on the actual data of a tire enterprise, and the sorting efficiencies for the two systems are compared. In addition, more efficiency simulation experiments are performed by adjusting the stock keep unit(SKU)quantity, and the effects of SKU quantity on the sorting efficiency for the two systems are investigated. It is found that the influence of SKU quantity on the operation efficiency in decentralized sorting systems is less significant than that in centralized sorting systems.
