基于总成本最小的多式联运运输方式选择

运输总成本是多式联运企业选择运输方式最优先考虑的因素,而总成本最小是目前大多数多式联运企业追求的目标。通过运筹学中的网络图理论构建多式联运运输网络图,基于总成本最小建立模型,将求解最短路径的Dijkstra算法用来求解模型,在求解实例问题过程中印证了整个模型的可行性。

基于作业流程的国际海空联运航线成本分析

根据海空联运的操作流程,海空联运航线成本可分为海运段成本与空运段成本,每个阶段的成本又由始发地费用、运费、目的地费用三部分组成,所有成本按重量分等级计算海空联运航线单一费率,最后以上海-迪拜-汉堡航线海空联运的案例作了进一步说明．     

协同理论在公路运输领域的应用

把协同理论应用到运输领域产生了协同运输理论,协同运输定量分析运量、运力的最优配置,并运用GIS为运输协同体的信息平台搜寻运输最短路径。协同运输组织系统需要以运输组织为核心,寻找市场机会、选择协同伙伴、制订协同方案,最终形成自组织运行系统。我国目前可以从协同运输最原始的雏形－货运合并开始,培养公路货运中间层、发展运输信息化,构建立体化、多元化的公路运输系统。     

多式联运同盟敏捷性评价研究

敏捷性是多式联运同盟的核心能力。在建立多式联运同盟敏捷性评价的综合评价指标体系基础上,利用层次分析法分析各指标的权重,然后采用灰色多层次关联分析评价不同多式联运同盟的敏捷性,用实例表明了该算法的有效性和实用性。

Sustainability reporting,materiality, and accountability assessment in the airport industry

Air travel is, nowadays, recognized as being one of the most popular modes of transport. Air transport is among the most significant contributors to the world gross domestic product and is accountable for a great environmental and social impact. Driven by the well‐established sustainability discourse and the vital role businesses can play in disseminating the sustainable development concept, this paper attempted to map airport industry's most material operational aspects and assess airport operators' accountability level on disclosing corporate information regarding airports' economic, environmental, and social performance. In this context, 33 reports and 903 material issues representing 193 international airports were reviewed and assessed, and a methodology for benchmarking the accountability level of best reporting airport operators was developed, showcasing materiality assessment as a useful management tool for strengthening airport operators' business strategy and enhancing their corporate performance. The paper indicated that (a) customer focus (i.e., health, safety and satisfaction), economic viability, and business continuity and preparedness are operational aspects of high materiality and (b) the disclosure level, especially concerning specific performance indicators, is still moderate. In conclusion, this study has shown that materiality assessment gains ground as a management tool among airports' management teams and the completeness of Sustainability reports is positively correlated with the “level” of adherence as described by the Global Reporting Initiative.     

中蒙俄经济走廊建设中内蒙古与蒙、俄产能一体化分析——以钢铁、水泥为例

在“一带一路”倡议背景下,内蒙古凭借地缘优势、人文优势正在积极参与中蒙俄经济走廊的建设,并发挥着重要作用。内蒙古通过对蒙、俄输出钢铁和水泥,对促进内蒙古的经济增长起到了一定的积极作用。本文利用TVP－VAＲ模型实证检验证实,内蒙古对蒙、俄在钢铁、水泥的产能输出,短期内对第二产业的增长影响较为显著,但中期影响减弱,长期影响不明显。因此,内蒙古应抓住机会,通过产能一体化进一步化解钢铁、水泥过剩产能,从而实现产业结构升级和创新发展。     

THE LIMITS OF INFRASTRUCTURE: Public Transport in a Post-colonial City

Since the 1940s, the people of the neighbourhoods (kampungs) around Surabaya's derelict Ngagel industrial estate have made a living by repurposing the remains of what was once one of Asia's most modern road, rail and industry networks. The remains—in the form of leftover fuel, labour and factory parts—are used to rebuild and repair improvised transport vehicles like bicycle-taxis (becak), minibuses (bemo) and motorbike-taxis (ojek). The repurposing happens at the limits of a capital-intensive heavy infrastructure of factories, trams and buses. The limits are those points where such infrastructure fails and a household-funded mosquito-fleet of light vehicles succeeds. Repurposing gives those who do it a right to infrastructure by providing the city with much-needed public transport. In Surabaya, public transport begins at its limits through the improvisations of people who live in the productive remains of capital-intensive heavy infrastructure. These people live in Surabaya's deindustrialized urban core, where life is made in the ruins of infrastructure through the breaking-down of it, the reworking of it, the right to it, and the leakage of it—the means through which rank-and-file people rather than states and corporations forge infrastructure.
