地铁公司行政部门绩效考核研究

地铁公司本身及其员工个人的发展都需要在行政部门引进绩效考核,在把握公平性、连贯性与差异性三大原则的基础上,可以从考核评价指标、考核评价方法、考核评价程序的运用等方面着手来构建行政部门的考核体系。     

北京地铁晚间和非高峰期用作城市物流系统探讨

北京市区物流量越来越大,但受交通拥堵状况影响流通效率低下,而北京地铁四通八达,晚间却在闲置,论文提出把北京地铁在晚间和非高峰期用作城市物流系统的观点,并分析了必要性和可行性,以及北京地铁用作物流系统的技术需求和现实障碍,最后针对性地提出了一些政策建议。     

地铁正外部性作用范围的计量研究

针对地铁正外部性作用范围的问题,在总结同类研究的基础上,提出了站点周边房地产价格受到地铁的影响是通过“人”的因素而产生作用的,这种作用可通过选乘地铁的概率进行考察.本文在分析影响“人”选乘地铁的因素的基础上,构建了地铁选乘的logistic模型.通过北京市调研的数据验证模型,观察通过调整变量X4对选乘概率的影响情况得到...     

北京地铁车站室内设计之构成艺术应用浅析

构成艺术不仅是现代艺术中影响广泛的一种艺术形式,也是自德国包豪斯以来一种重要的现代设计理论体系,它对地铁车站空间的设计起到一定的影响。简要地论述了构成艺术与地铁车站室内设计的关系,同时通过调研北京地铁线路中几个有特色的地铁车站,分析其空间以构成艺术为主要装饰手法的表现方式,提出了结舍地铁车站空间的特点,借鉴和吸收构成艺术的精髓以提高我国地铁车站空间设计水平的观点。     

基于计算实验方法的地铁工程成本管控行为激励机理研究

发展城市地铁是城市轨道交通建设的主导方向,也是地铁建设企业实现可持续发展的重要保障。大规模地铁建设需要对成本管控行为的机理、规律有进一步认识和研究。基于激励视角,识别了我国地铁工程成本管控行为激励因素,运用计算实验方法建立模型,设计实验情景,设置实验参数,研究了激励因素对地铁工程成本管控行为的作用机理。实验结果表明：环境、工作、回报、管理因素对地铁工程成本管控行为变化具有显著影响。其中,环境因素具有调节作用,工作因素具有推动作用,回报因素具有促进作用,管理因素具有引领作用。实验结果可为地铁工程成本管控提供启示与借鉴。     

北京地铁14号线区间隧道下穿卢沟桥 暗涵工程注浆加固

在建的北京地铁14号线03标段是双洞单线隧道,采用暗挖矿山法施工,在北京西南城郊的卢沟桥区域下穿已经建成运行的南水北调中线既有管廊段工程。为保证该管廊段构筑物的绝对安全,地铁隧道工程在暗挖施工中采用了超前预注浆和后续径向补充注浆的施工方案。从工程效果评价检查情况看,后续径向补充注浆工程对管廊段的保护起到了重要的作用。本文主要是对这一专项施工过程进行详细论述,以期为类似的工程施工提供借鉴。     

浅析地铁公司办公室制度建设与服务效能的提升

制度建设是提升办公室服务效能的有效途径,但在具体的制度设计中还存在一些不足,可以从以制度定规范、以制度强职能、以制度优作风等方面着手推动服务效能的提升.     

Forecasting and uncertainty in the economic and business world

Forecasts are crucial for practically all economic and business decisions. However, there is a mounting body of empirical evidence showing that accurate forecasting in the economic and business world is usually not possible. In addition, there is huge uncertainty, as practically all economic and business activities are subject to events we are unable to predict. The fact that forecasts can be inaccurate creates a serious dilemma for decision and policy makers. On the one hand, accepting the limits of forecasting accuracy implies being unable to assess the correctness of decisions and the surrounding uncertainty. On the other hand, believing that accurate forecasts are possible means succumbing to the illusion of control and experiencing surprises, often with negative consequences. We believe that the time has come for a new attitude towards dealing with the future. In this article, we discuss the limited predictability in the economic and business environment. We also provide a framework that allows decision and policy makers to face the future — despite the inherent limitations of forecasting and the uncertainty, sometimes huge, surrounding most future-oriented decisions.     

城市轨道交通对沿线周边住宅价格的影响分析——以北京地铁四号线为例

城市轨道交通是一种公益性、经济外部性都很强的大型公共基础设施,其高效的通达性促进周边住宅升值明显提升。科学地分析城市轨道交通对住宅价格的影响效应,对合理规划沿线住宅项目开发、调整城市空间布局具有重要意义。本文以北京地铁4号线周边住宅作为研究对象,对影响住宅价格的因素进行回归分析,并构建了半对数形式的特征价格模型。经过分析得出住宅距离轨道交通线路的远近、所处的位置、周边1000m范围内公交站点的数量以及住宅至市中心或中央商务区(CBD)的实际距离四个变量对住宅价格的影响比较显著,并且探讨了地铁站点与住宅距离减少,对住宅增值的作用。     

Layer approach to ownership in 3D cadastre in the case of underground tunnels

The paper focuses on approaches to the registration of real property rights in the case of underground or subway tunnels in different EU countries: Austria, Bulgaria, Czech Republic, Croatia, Greece, Poland, Slovenia, and Sweden. The authors conducted analysis on the registration of rights to subway tunnels in the chosen countries, including its effectiveness in ensuring appropriate property rights to construct and exploit tunnels. Special attention was given to limitations related to the lack of legal provisions vertically dividing space, i.e. into layers, and referring to the ownership right to the layers. Benefits which might be achieved by the introduction of a 3D real property subdivision were pointed out. The analysis of the available data concerning the geometry of subway tunnels in particular countries was presented. The authors tried to answer the question whether the accessible data concerning the geometry of subway tunnels allows to generate a 3D geospatial model of a constructed object, and to specify the space which should be determined as a 3D parcel in the 3D real property cadastre, for the purpose of registering property rights for the object (the tunnel).
