【摘要】 车流组织综合优化是把装车地的始发车流及技术站的改编车流作为一个整体来研究,寻求它们之间的最佳匹配和协调。本文在既有的装车地车流优化模型及技术站车流优化模型的基础上,进行了仔细的筛选、改造及移植,抓住了使两种不同性质车流相容和转化的条件,恢复了它们之间固有的联系和制约。这些,都分别反映在本文提出的线性0-1规划综合优化模型及二次0-1规划综合优化模型之中。由于模型所描述的对象,是一个大规模的铁路网络系统,是否有一个与之匹配的有效算法,至关重要。本文推荐移植的算法及应用软件,稍作修改及补充,即可付诸实用。更多还原

【Abstract】 In the synthetical optimization of wagon flows, the original wagon flows and the technical wagon flows are taken as a whole in searching for their optimal matching and harmonizing with each other. In this paper, through careful selection, improvement and transplantation on various existing models for the optimization of wagon flows, we gain the conditions for the admissibility and transformation between the two different types of wagon flows and reveal their intrinsic connection and mutual restriction, all of which are reflected in the linear and the quadratic 0-1 programming models for the synthetical optimization of wagon flows presented here. An effecient algorithm available to the above quadratic 0-1 programming is recommended.更多还原
