集装箱货运仿真模型在珠三角港港口投资方案评估(英文)

In the Pearl River Delta (PRD), there is severe competition between container ports, particularly those in Hong Kong, Shenzhen, and Guangzhou, for collecting international maritime container cargo. In addition, the second phase of the Nansha terminal in Guangzhou’s port and the first phase of the Da Chang Bay container terminal in Shenzhen opened last year. Under these circumstances, there is an increasing need to quantitatively measure the impact these infrastructure investments have on regional cargo flows. The analysis should include the effects of container terminal construction, berth deepening, and access road construction. The authors have been developing a model for international cargo simulation (MICS) which can simulate the movement of cargo. The volume of origin-destination (OD) container cargo in the East Asian region was used as an input, in order to evaluate the effects of international freight transportation policies. This paper focuses on the PRD area and, by incorporating a more detailed network, evaluates the impact of several infrastructure investment projects on freight movement.     

基于NAPA的船舶结构设计方法研究

以NAPA软件为平台,以某散货船为例,通过对一般构件、肘板、开口的表格化建模方法、图形输出方法和剖面特性输出方法的研究,将三维设计概念引入到船舶结构设计中,进一步阐述了现代结构设计方法,并与传统结构设计方法相比较,发现结构设计效率大大提高。

三用工作船挡货栏杆结构设计与分析

诸多功能集于一身的三用工作船(Anchor Handing Tug Supply Vessel, 以下简称AHTS)在有限的甲板空间内既要保证载货面积,又要预留足够的人员通行和设备空间。挡货栏杆作为甲板上主要的结构件,其设计一直是个难点。本文以某AHTS为例,就挡货栏杆的立柱、顶梁、拦挡构件和设备基座等主要组成部分及其结构特性进行概述,并给出立柱受货物侧向压力和受绑扎件集中力的强度校核方案,为挡货栏杆的设计提供参考和借鉴。     

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.
