摘要
在对客运专线线路走向决策的特点进行深入细致分析的基础上,围绕客运专线线路走向方案优选系统的建立,开展了理论与应用研究工作;运用系统工程和软件工程理论与方法,采用数据仓库技术提出了客运专线线路走向方案优选系统中数据管理方法,并构造了相应的数据仓库结构以及客运专线线路走向方案优选系统功能结构,实现了客运专线线路基本走向决策支持系统关键技术;运用开发的"客运专线线路方案优选系统",实现计算机辅助进行成都至重庆客运专线线路走向方案的多目标决策分析。经反复筛选确定了成都至重庆客运专线线路走向的五个非劣方案,建立决策指标体系,进行权重计算和分析,确定了客运专线线路走向方案的优先顺序。
Based on the detail analysis of the characteristics of decisionmaking for the alignment of dedicated passenger line, the thesis studies the theory, methodology and application focusing on optimizing the solutions for the alignment of the line. The theory and methodology of system engineering and software engineering are applied, data management method for the alignment optimization system put forward by using the data warehouse. The data warehouse structure and system functional structure for the alignment optimization are designed and key technologies of decisionsupport system for the alignment of dedicated passenger line are developed. The computeraided multiobjective decision making analysis for alignment optimization of Chengdu-Chongqing dedicated passenger line is fulfilled. Finally, five pareto solutions are determined, decisionmaking indexing system is built up and weighing calculation and analysis are carried to finalize the priority sequence of the solutions for dedicated passenger line.
