散装水泥码头装卸系统物流仿真研究

Logistics simulation of bulk cement terminal handling system

以A港区某散装水泥码头物流系统为研究对象,基于离散事件动态系统理论,建立实现散装水泥码头物流功能的逻辑模型。针对码头最大装船能力与水平运输能力不匹配的问题,通过对码头筒仓数量和容量、船舶等待时间、泊位利用率、码头通过能力等的分析,给出不同策略组合的水泥筒仓选型方案。梳理码头装卸系统中各子系统的逻辑关系,采用仿真分析技术,确定建设投资合理的筒仓配置,从而提高水泥码头的出运能力和水泥厂总体效益。研究成果可为散装水泥码头出运能力优化提供重要依据,亦可为此类散货码头装卸系统筒仓数量和容量的选取提供参考。

Taking the logistic system of a bulk cement terminal in port area A as the research object,a logical model is established based on the discrete event dynamic system theory to realize the logistics function of the bulk cement terminal.The selection scheme of cement silos with different strategy combinations is given to solve the mismatch between the maximum loading capacity of the terminal and the horizontal transportation capacity through analyses of the number and capacity of terminal silos,vessel waiting time,berth utilization,terminal capacity and so forth.Meanwhile,this paper sorts out the relationship of each subsystem.It uses simulation technology to determine silo configurations to improve the shipping capacity of the cement terminal and the overall benefit of the cement plant.The research results can provide an important basis for optimizing terminal shipping capacity and a reference for selecting the number and capacity of silos in the loading and unloading system of such bulk cargo terminals.
