摘　　要：制定计算机编制全路直通客车方案优化系统设计原则。提出实现客车方案编制的三种基本算法是:以单线会车附加时分系数为基础进行方案铺画的附加时分法;以时间推进、分段切割来预测列车动态轨迹和事件的事件预测法;以客车轮廓图为基础,通过循环求解、层层逼近目标值的层次逼近法。通过对这三种方法的分析和比较,选择了层次逼近法作为客车方案铺画的方法。对系统研究过程中车次的识别、迂回经路处理、北京枢纽间隔检查、图形处理等关键技术进行阐述,并提出设计系统的程序功能。The design principle of computer preparation of the optimized system-wide through passenger train work diagram is regulated. Three basic algorithms for the passenger train work diagram solution are put forward: a) Based on the single-track meeting with additional time system; b) event forecasting system with time approach and segmentation to forecast the train dynamic trajectory and events; and c) the hierarchy approach method which is based on the passenger contour diagram to find the cycle solution, and approach the target value layer by layer. Through comparison, and analysis, the hierarchy approach method is selected to prepare the passenger train work diagram. The paper describes such key technologies as the train identification, route processing, interval inspection of trains in Beijing Junction, and graph processing. It puts forward the programming function of the design system.
