中文摘要：
客运专线与平行既有线的合理分工及使用,对方便各类旅客出行和增加铁路运营效益有着直接的影响.本文综合分析了影响客运专线与既有线分工的社会因素和经济因素;基于福利经济学原理,论证了客运专线与既有线的合理分工应是一种帕累托的改进过程,合理方案应是实现帕累托最优状态.藉此,提出了兼顾效率与公平的合理分工基本原则.依据分工原则,运用定量优化理论建立了铁路运输收益和旅客收益最大化优化数学模型,并从优选思想与启发算法相结合的角度,提出相应的求解方法.
英文摘要：
Work-division directly influences convenient travel of passengers and railway operating benefit,between existing lines and paralleling passenger dedicated lines. Based on welfare economics, the social and economic influence of reasonable work-division between the passengers dedicated line and the existing one is analyzed. It is demonstrated that reasonable work-division should be the Pareto improving process, and a reasonable scheme is to bring about Pareto optimal condition that let lines be used. As a result, Principles of work- division combined equity and efficiency are put forward. According to the analysis conclusion, an optimal model is established based on revenue maximization of railway enterprise and passengers. Then, an advance solution method and schemes are also present in the guidance of optimal conditions and heuristic algorithm.
