1自动补货系统补货缓存优化显示文摘为提高自动分拣系统作业效率、降低补货设备投入成本,在对自动补货系统中补货缓存作业过程分析的基础上,建立补货缓存设备输入输出平衡模型,提出补货缓存满足分拣作业的最优条件及临界条件;根据自动备货系统与分拣系统之间的布局关系,建立补货缓存中货物到达过程的数学模型和补货缓存长度的优化模型;设计'先聚类,后排序'的启发式聚类方法对备货系统的品项分配进行优化,仿真结果显示,优化后的品项分配与按照总量排序分配方法相比,补货缓存长度减少约9%。王艳艳 吴耀华 吴颖颖 牟善栋 2012机械工程学报2012,48,24:5
2A MODEL AND AN ANALYTICAL METHOD FOR CONVEYOR SYSTEMS IN DISTRIBUTION CENTERS显示文摘The design and operation of high volume conveyor systems in distribution centers are important due to its high cost, large footprint and critical role in the system. However, there is no analytical model available. In this paper, we study the characteristics of the conveyor sortation system, develop a generic model of a complex conveyor network. We then use the Delay and Stock abstraction to develop an approximate analytical method using sample path analysis and dynamic network flow model. The decision variables include length of accumulation segments and the speeds of conveyor components aforementioned decision variables. This analytical solution provides faster analysis, insights and useful subgradient with respect to the decision variables.Ying WANG Chen ZHOU 2010Journal of Systems Science and Systems Engineering2010,19,4:2
