【摘要】 阶段计划是编组站作业计划的核心部分,传统手工编制方法的弊端日趋明显。随着我国铁路现代化建设步伐的加快,作为铁路调度指挥自动化重要内容之一的编组站阶段计划的自动化编制辅助决策系统的研究迫在眉睫。 本文从我国编组站的实际出发,利用系统工程的思想,对阶段计划编制系统进行详细的分析,对阶段计划计算机辅助决策系统的结构、功能和实现过程进行了初步探讨。对其中的一些技术问题进行了研究。论文的主要工作为: ● 对我国编组站的实际情况作了概述,以徐州北站为背景,对编组站阶段计划编制的过程、要求、方法进行了系统的分析。论述了阶段计划编制所涉及的基本数学模型。在此基础上,提出了各种模型集成并纳入人的作用的编制思想。 ● 从系统工程角度出发,详细探讨了阶段计划编制系统的结构和功能。研究了系统的模型库、方法库、知识库,为实现阶段计划的计算机辅助决策奠定了基础。 ● 针对实际中存在的跨平台数据访问的问题进行了研究。对客户机/服务器体系作了描述,在FTP的网络文件传输的基础上,利用WindowsSockets网络编程方法,设计实现了网络功能。采用ODBC技术实现了防问数据。 ● 对编制阶段计划人机交互系统进行了研究开发。设计了人机交互系统的功能和合理的人机交互界面,对基于面向对象的阶段计划编调系统框架进行了讨论。最后,重点对系统软件开发过程中的一些技术问题进行了专门研究。包括:动态链接库(DLL)的使用、图形坐标系统的原理方法、图形系统的处理与优化。

【Abstract】 Phase plan, which is the main part of the task in marshalling station has obvious shortcoming in its obtaining way by the means of traditional method. With the fast step of railway’s modernization, the ADSS for the automation of compiling station’s phase plan has been come up with.According to the fact of our marshalling stations, taking advantage of the system engineering, the paper details on the system of compiling phase plan and probes the ADSS’s structure,funtion and achievement .And discusses some technology problems. The main task of the paper is below:Summarizes the real situation of our marshalling stations, and with the example of xuzhou station, analyse the requirement and methods of compiling marshalling stations’ phase plan. Based on this, comes up with the idea of assembling all kinds of models and factitious function.From the aspect of system engineering, details on the structure and function of the phase plan compiling system, researches on the models base, methods base and knowledge base which establish the foundation for the achievement of the ADSS.Aiming for the problem of accessing data on different flats, gives some research, limns the server/client system, and based on the transferring FTP net files,uses the method of windows’ sockets network programming, devises and achieves the network function, fulfill data accessing using ODBC technology.Researches and develops the man-machine dialog system. Devises the system’s function and reasonable man-machine interface, discusses the framework of the phase plan compiling and adjustment system based on OOP.IncIudesing the use of DLL,the principle of diagram and coordinate system, and the management and optimization of diagram system.
