摘要
为了解决我国铁路货运站数量过多、布局过密、难以产生规模效应等问题,借鉴经典的糖域(Sugarscape)模型,将Agent的智能性和人元模型中主客观属性综合考虑的特性相结合,建立了基于Agent-人元模型的铁路货运站布局模型。该模型将货主视为自主Agent,将货运站作为资源,Agent在寻求资源的过程中能量会发生变化,并根据自己的能量多少来引起货运站价值的变化。按照模型中设定的规则,对该模型进行了仿真分析,得到了一定范围内的货运站布局方案。从仿真结果可以看出,该模型将所研究的车站划分成保留站、待定站和取消站三类,这对于货运站布局优化以及战略装车点的设置具有指导性意义。
In view of the redundancy of railway freight stations in China,their over-densely distribution and inability to generate benefit of scale,the paper draws from the classic Sugarscape model,and,based on the agent-human-element model which incorporates the intelligence of the Agent model into the human-element model characterized in its comprehensive consideration of both the subjective and objective attributes,formulates the arrangement model of railway freight stations.According to the model,the cargo owner is seen as an automatic agent,the freight stations as resources,and in its search of resources,the agent would have its energy varied which would accordingly cause changes to the values of the freight stations.In light of the rules set in the model,the paper analyzes the model in a simulation study and obtains the arrangement scheme for freight stations within a certain range.In the study outcome,the stations are divided into stations to keep,stations awaiting decision,and stations out of commission,which would be of value as guidance to the arrangement optimization of freight stations and the placement of strategic cargo loading points.
