大宗物资运输系统的计算机模拟与优化分析

大宗物资 (如煤炭、石油、钢铁、汽车、矿石、粮食、建筑材料等 )运输系统是对国民经济发展有重大影响的一类物流系统 ,对其进行系统优化分析和优化设计将产生可观的社会与经济效益。各种运输系统本质上都是非常复杂的随机服务系统 ,难以使用通常的解析方法建立系统运行的数学模型。计算机系统模拟是最有效、最经济的定量分析手段 ,利用其模拟运行结果可以方便地分析系统的运行状况并进行优化分析。本文在分析大宗物资水路运输系统的一般运行规则基础上 ,设计了一个较为通用的系统模拟模型 ,并对一个水路运输系统进行了模拟运行和系统优化分…

Computer simulation and optimization about large-quantity cargoes transportation system

Large-Quantity Cargoes Transportation System, which is very important in national economic development, is analyzed and its simulating model is set up with computer system simulating technology. A waterway transportation system is taken as oerating example. The results produced by developing the model are analyzed and optimized and their accuracy are studied with statistics theory. The judgement of system steady state is also successfully supposed.
