呼和浩特铁路局货运营销管理信息系统

铁路货运营销管理信息系统是呼和浩特铁路局于2003年建立的面向"铁路跨越式发展"的大型综合铁路货运营销管理系统.系统工程将重点围绕货运营销业务的综合管理和可视化分析,以现有的贷票系统和贷运营销与生产管理系统(FMOS)为基础,对相关信息系统进行整合,结合Web-GIS技术强大的空间分析处理能力,分别建立路局级、站段级货运营销管理信息系统.系统实现了货运收入统计分析、货运吸引区电子地图、基于货运计划、货票和重点货主的营销分析等功能,并结合客户关系管理(CRM)理念,着重体现了对重点货主的营销分析.这一系统的建设将大大提高呼和浩特铁路局货运营销管理水平,为提高铁路运输企业市场开发能力提供强有力的手段.

The future of trucking technology in Brazil: results of a technology forecasting model

Abstract

The aim of this article is to identify a set of technological events related to the Brazilian truck fleet that are well placed hierarchically regarding their possibility of occurrence and pertinence for the horizon year of 2021. For this we propose and apply a Technology Forecasting Model for trucks (called TFM/Trucks) based on the Delphi technique, considering 28 technological events associated with six internal forecasting dimensions: safety, efficient use of energy and alternative fuels, materials technology, operational schemes, comfort and environment. The ranking of the technological events, considering hypothetical situations for analysis, indicate significant concern over the safety dimension, with four of the five events (passive safety and active safety) classified among the 10 events with the greatest chance of occurring and pertinence, irrespective of the panelists' degree of specialization. The environmental dimension, with respect to the predominance of electric powered trucks with lower level of atmospheric pollutants, was always in one of the first two positions, regardless of the situation studied. In the final ranking, the five best-classified events represented the dimensions of safety, environment, materials technology and comfort, with environment and passive safety predominating.     

铁路货车重车重心合理限高的研究与试验

重车重心限制高度是我国铁路基本技术标准之一，起着指导现场装车、保障行车安全的重要作用．本文分析了影响货物列车安全运行的因素，给出衡量车辆倾覆稳定性的主要指标，并论述了双层集装箱重车重心高度运行试验，遂渝线提速综合试验及胶济线列车交会试验的试验方案和试验过程．在分析试验数据的基础上，得出了双层集装箱重车重心高度为2400mm时能够保证行车安全的结论．此外，根据敞车、平车和棚车等主要车型在环形试验线和运营线路上进行的重车重心高度试验，分析了敞车和平车重车重心高度设置为2400mm、棚车重车重心高度设置为2200mm时的运行稳定性和平稳性的要求．

A case study on the coordination of last trains for the Beijing subway network

Passengers may make several transfers between different lines to reach their destinations in urban railway transit networks. Coordination of last trains in feeding lines and connecting lines at transfer stations is especially important because it is the last chance for many travellers to transfer. In this paper, a mathematical method is used to reveal the relationships between passenger transfer connection time (PTCT) and passenger transfer waiting time (PTWT). A last-train network transfer model (LNTM) is established to maximize passenger transfer connection headways (PTCH), which reflect last-train connections and transfer waiting time. Additionally, a genetic algorithm (GA) is developed based upon this LNTM model and used to test a numerical example to verify its effectiveness. Finally, the Beijing subway network is taken as a case study. The results of the numerical example show that the model improves five connections and reduces to zero the number of cases when a feeder train arrives within one headway’s time after the connecting train departed.
