Air cargo operations: Literature review and comparison with practices

This study reviews the literature on air cargo operations and compares theoretical studies with the practical problems of airlines, freight forwarders, and terminal service providers. In particular, we review studies in which mathematical models were used to identify the essential characteristics of air cargo operations, such as the intrinsic differences from passenger operations, and to explore the service processes in air cargo operations. The typical models used in previous studies are summarized. We then highlight the insightful findings from an industrial interview and present the gaps between previous research and practical realities. We finally discuss the new research opportunities of air cargo operations according to the gaps.

Status Quo and Future Development of Shanghai Air Cargo Industry

Air cargo industry has become a new growth point of Shanghai economy. It also plays an important role in China's air cargo transport. This paper analyzes the air cargo industry status quo and future trends from the aspects of Shanghai airport, cargo facility, air cargo traffic (ACT) and its structure. Then it prospects Shanghai airport and its cargo facility's future development. After that it completes the regression analysis and elastic analysis of air cargo traffic and total foreign trade value (TFTV) with SPSS software. Based on this, it forecasts the future trend of air cargo traffic. The results show that Shanghai airport serves beyond the scope of Yangtze River Delta, air cargo traffic has significant imbalance and will grow to around 5.3 million tones with TFTV growth by the end of “twelfth five-year” period though slower than TFTV, and the airport cargo facilities can accommodate the air cargo industry development. Finally, some useful countermeasures for stimulating Shanghai air cargo industry are put forward.

打破"诸侯经济"创双赢

上海建设国际航运中心,确定了洋山深水港的建设项目,由此带来了上海港和宁波港激烈的货源之争,而更大的竞争压力来自釜山等东北亚大型港口。面对这样的形势,上海、宁波两港应积极合作,一致对外,争取早日把上海港建成国际航运中心,同时使宁波港得到迅速发展。当“错位发展”的合作形式遇到困难时,以资本为纽带的“港口联盟”可能会是一种好的合作形式。     

9 000 t新型不锈钢化学品船结构设计

为了适应品种繁多的化学品运输,开发了适装性强的9000t不锈钢化学品船。设计时采用了奥氏体-铁素体双金属相不锈钢材料,很好地满足了高蒸气表压、高装运温度、高货品密度的设计要求,明显减轻了不锈钢重量、降低了造价,并改善船厂不锈钢施工的工艺。本文从五个方面讲述了结构设计中所需要特别注意的问题。
