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 order to solve the problems of excessive number of railway freight stations, over-dense distribution and difficulty in generating scale effects, the classic Sugarscape model is used to combine the intelligence of Agent with the characteristics of subjective and objective attributes considered in the meta-model , Established a model of railway freight station layout based on Agent-human element model. The model treats the owner as an autonomous agent and the freight station as a resource. The agent changes energy in the process of seeking resources, and changes the value of the freight terminal according to his own energy. According to the rules set in the model, this model was simulated and analyzed, and a certain range of freight station layout plan was obtained. It can be seen from the simulation results that the model divides the stations studied into three types: reservation station, pending station and cancel station, which is instructive for the optimization of freight station layout and the setting of strategic loading point.
