本义在分析现行的车站通过能力计算方法的基础上,提出了采用计算机进行系统模拟的基本原则和算法;根据车站作业的特点,将车站元素划分为允许产生延误的基本元素和不允许产生延误的中间元素;分析了办理一次作业的必要和充分条件;提出了有关平行进路,多种作业方案等问题在模拟计算中的处理办法。最后,介绍了模拟计算程序的总体结构、各程序模块的主要功能、基本数据结构以及程序主模块的逻辑框图。
Based on the analysis of the current station capacity calculation method, this paper proposes the basic principles and algorithms of computer simulation system. According to the characteristics of station operations, the station elements are divided into the basic elements that allow delay and the delay is not allowed Middle element. The necessary and sufficient conditions for handling one operation are analyzed. Some solutions to the problems of parallel approach and multiple operation schemes in simulation calculation are put forward. Finally, the general structure of simulation calculation program, the main function of each program module, the basic data structure and the logic block diagram of the main program module are introduced.
