集装箱海运网络脆弱性风险控制

为保障集装箱海运网络稳定运行,提出集装箱海运网络的脆弱性风险控制方法。选取集装箱海运网络平均度、集装箱海运网络孤立节点比例、集装箱海运网络效率等作为脆弱性风险控制指标,采用熵权法计算各指标权重,基于指标权重构建脆弱性风险划分模型,将集装箱海运网络的脆弱性风险划分为不脆弱～非常脆弱5个等级,根据脆弱性风险等级划分结果,提出对应的策略与建议,实现集装箱海运网络脆弱性风险控制。实验结果显示该方法可有效获取脆弱性风险等级划分结果,并有效降低集装箱海运网络脆弱性风险。     

新型冷藏集装箱后门设计

冷藏集装箱后门一般采用锁杆控制形式,以确保箱内货物运输安全。随着集装箱用途的多样化发展,集装箱用作仓库的需求上升,这意味着箱门开关的频率增加,而后门的锁杆控制形式不便于开关门操作。针对该问题,本文提出新型冷藏集装箱后门设计方案,使之既能保证集装箱货物运输安全,又能满足集装箱作为仓库使用的要求。     

基于地理信息系统的危险货物集装箱堆存监控系统应用

Recent progress on wave induced loading measurements in warships

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form.

Impact of regulation on the performances of long-distance transport services: A comparison of the different approaches in Sweden and Norway

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.
