重庆港危险货物码头安全管理中的问题及对策

分析目前重庆港危险货物码头安全管理中存在的问题,将危险货物从业单位作为安全监管的重点对象,依据危险货物港口作业认可、危险货物港口作业申报和危险货物作业场所建设审批等制度,从安全设施和环保设施的投入、作业范围的许可、人员资质的认定以及安全设备和事故救援体系的建立等环节评价危险货物码头安全管理状况,依据其特点以及存在的关键问题进行总结并提出对策。     

基于突变理论的铁路危险货物办理站安全评价

通过对目前铁路危险货物办理站常用安全评价方法的分析,这些方法存在的缺点主要是评价中参数值的选取、各评价指标权重的确定以及评价因素重要性的确定等问题,因易受到参评人员主观的影响,而导致评价难以获得客观结果.基于突变理论的模糊动态评价方法,通过对评价目标进行多层次分解,根据突变归一公式进行量化递归运算,分别计算出不同时期办理站安全总突变隶属函数值,从而实现对办理站安全状态的模糊动态分析与评价.示例表明,该方法是合理可行的.     

危险品货物运输全程监控分析

在研究危险品货物运输监控现状的基础上,提出基于RFID、GPS、GPRS和GIS的危险品货物全程监控模型以及基于RFID和IC卡的"人、车、货"匹配模型,有效的实现危险品货物运输的全程监控。在此基础上设计车载终端体系结构并开发了显示界面,实现车辆状态信息、货物状态信息的显示和路线三维模拟。最后基于ArcgisEngine开发监控系统的显示界面,实现车辆实时显示、轨迹回放和位置查询等,并用模拟数据进行验证。     

铁路危险货物突发事故应急方案生成及其贝叶斯建模技术分析

随着全路危险货物应急管理工作不断深入开展,铁路危险货物突发事故应急管理缺乏规范标准的问题日益突出,而铁路危险货物在铁路货物运输中占有非常重要的地位。对铁路危险货物应急方案的生成进行分析,针对预案管理的各个环节,制定应急方案的生成流程,在此基础上,应用贝叶斯算法对应急方案生成流程进行建模,为进一步对应急方案生成流程进行分析、优化奠定基础。     

《鹿特丹规则》货物交付制度若干新变化之比较研究

货物交付制度是运输合同法律的重要内容。《鹿特丹规则》系统规定了货物交付制度,确立了收货人接收交付和确认收到货物的义务,规定了不同运输单证下的交付规则,与现行的法律比较存在诸多差异。中国航运企业应研究、借鉴货物交付新规则,完善货物交付制度。     

蒙华铁路高家山危岩特征成因及裂隙变形分析

为研究蒙华铁路高家山隧道洞口危岩的稳定性,利用不连续介质二维离散程序进行模拟分析,选取洞口典型危岩块体,对组成危岩体的泥岩、砂岩按照岩体质量分级进行物理力学参数赋值,得出在初始应力平衡条件下,边坡体仅出现少量裂隙,而在风化卸荷作用下,边坡体表层20 m范围内出现朝临空方向变形的应力张拉区,特别是在泥岩附近的陡崖与陡坡过...     

An advanced solution for efficient logistics management at both company and network level

This paper proposes an advanced solution for efficient logistics management in urban areas based on a unified scheme able to address both static and dynamic decision making at a company and network level. The proposed solution generates the most efficient urban distribution plan utilizing an evolutionary metaheuristic approach and a backpressure framework that provide competitive scheduling and routing decisions. An empirical study based on real data is conducted assessing the performance of the proposed advanced solution and the reported results of the evaluation experiments demonstrate its generality and robustness.     

Reducing the energy consumption of heavy goods vehicles through the application of lightweight trailers: Fleet case studies

Reducing the empty weight of articulated heavy goods vehicle trailers is one avenue that needs to be explored in reducing the carbon footprint of the road freight industry as a whole. A statistical analysis of two heavy goods vehicle fleets operating in the United Kingdom has helped to identify double-deck trailers used in grocery haulage and ‘walking-floor’ trailers used in bulk haulage as two examples of trailers that can benefit significantly from lightweighting. Energy consumption of numerous articulated heavy goods vehicles is quantified through an idealised drive cycle analysis reflecting a long haul journey over a highway. This energy analysis allows for a mass energy performance index to be established. The analysis has shown that reducing the empty weight of trailers by 30% can cause reductions of up to 18% and 11% in mass energy performance index for double-deck trailers and ‘walking-floor’ trailers respectively. Using this approach, trailers that will benefit the most from weight reduction can be identified systematically, allowing for lightweighting strategies to be implemented more effectively. Strategies to reduce empty trailer weight and improve vehicle utilisation are also discussed.     

依托“三互”深化海运危险货物谎报匿报治理工作实践

针对海事机构在海运危险货物谎报匿报查处中存在的缺乏源头信息来源、案件侦办过程复杂、单方面执法缺乏认可度等问题,大连海事局通过与海关部门建立“三互”合作机制,在信息交换、执法互助、联合研判和监管互认等方面进行合作,成立“三互联合查验工作室”,有效解决了上述问题,共同查处了多起谎报匿报危险货物案件,监管成效明显,具有较强的实践指导意义。文中就目前合作中存在的问题进行了分析,提出相应的管理建议,为“三互”合作机制长期运行提供可复制的实践经验。     

A scalable communication middleware for real-time data collection of dangerous goods vehicle activities

Recently, real-time monitoring of Dangerous Goods Transport has drawn a lot of attention, thanks to its capability to provide a better visibility on dynamically moving vehicles, particularly through a Web Mapping application. Yet, one of the challenges to be faced designing such a system is an effective architecture for real-time collection of telemetry and event data conveyed by the vehicle on-board system, such the Global Positioning System coordinates. In this paper, we have focused on optimizing the process for managing a large quantity of data transmitted via network sockets that use the Transmission Control Protocol. Then we prove the process efficiency through performance and scalability tests. The middleware is being implemented as a part of a project that aims to monitor the Italian petrochemical company Eni’s oil trucks shipment along Europe and USA territories.
