【摘要】 本文以铁路旅客出行效用最大化为出发点,建立了基于铁路旅客效用最大化的出行服务方案选择模型,该模型旨在为不同收入水平等级旅客生成符合其自身效用最大化的出行方案,此外,本文理论研究成果将应用到正在开发的铁路旅客出行服务方案查询系统。本文的研究目的是为铁路旅客提供更好的出行查询服务。主要工作概括如下：首先,对影响铁路旅客出行的因素进行了深入分析,认为旅行时间、费用、舒适度、发车时刻和到达时刻是主要影响因素,并对其进行了量化。其次,基于网上列车时刻表,构建了旅客出行的简易换乘服务网络图。基于换乘服务网络图将铁路旅客出行服务方案选择问题抽象为运筹学图论中的最短路问题。建立了基于铁路旅客效用最大化的出行服务方案选择模型,利用Matlab软件实现了求解模型的K最短路算法程序。再次,给出求解模型的具体步骤,对求解过程中关键问题的处理方法做了详细说明。以兰州到福州为例,按照模型的求解步骤,求出了符合不同收入水平等级旅客效用最大化的出行服务方案。最后,介绍了正在开发过程中的铁路旅客出行服务方案查询系统的构建情况,结合本文研究实例,展示了该系统的部分构建成果。更多还原

【Abstract】 The paper is based on maximizing the utility of railway passengers, the author created a choice-model of trip’s planning which based on maximizing the utility of railway passengers, the model aimed at generating the best trip’s planning for passengers of different income levels, moreover, results of theoretical studies will be applied to the inquiring system of trip’s planning of railway passengers. The researching purpose of this paper is to provide perfect inquiry services for railway passengers. The major works is summarized as follows:First, the author analyzed the impact factors of railway passengers’trips, picked up Travel time, Ticket price, Comfort, Departure time and Arrival time as the serious impact factors, then quantified these factors.Second, the author designed a simplified transfer network of railway passengers which based on the online train schedules. Based on the transfer network, abstracted the problem about selecting trip’s plans of railway passengers as the problem about finding the shortest path of graph theory in Operations research. Created a choice-model of trip’s planning which based on maximizing the utility of railway passengers, and based on Matlab, developed the K_shortest path algorithm program which could solve the model.Third, decomposed the specific steps of solving the model, and made some detailed introductions about dealing ways of the key issues in the process of solving the model. The researching case is from Lanzhou to Fuzhou, according to the steps of solving the model, found out the best trip’s plan which maximized the utility of those passengers.Finally, briefly introduced the developing situations of the inquiring system of trip’s planning of railway passengers which being developed at present, and combined the researching case of this paper, showed partial functions of the system in current.更多还原
