摘要
排队论是研究系统由于随机因素的影响而出现排队或拥塞现象的规律性的一门学科,在深入研究了排队论的基础理论后,应用该理论建立了U型自动化立体仓库的数学模型,并给出了该仓库模型的约束松弛条件。根据该模型可以求出自动化立体仓库系统的等待服务的货物数、货物的平均等待时间、系统内存在货物数等作业参数。最后应用建立的数学模型对某U型立体仓库进行了分析,分析结果表明该模型能够很好的计算评估自动化立体仓库系统的作业参数指标,为优化及评估仓库系统的可靠性提供了依据。
The queuing Theory is the subject that studied the influence of random factors then appear queuing or Regularity of choking phenomenon,queuing theory is further studied on the basic theory and then applicated,mathematical model of a ushaped AS/RS is established and Constraint conditions of relaxation is presented.According to this model the number of goods for service,the average waiting time for the goods and goods numbers in system etc operation parameters.Finally one u-shaped AS/RS is analyzed by using the established mathematical model,the results show that this model can calculate the operation parameters of AS/RS system very well in order to provide the reliability and optimization of the AS/ RS system.
