ABSTRACT As the key member states of the RCEP, China and Thailand will achieve more stable economic cooperation. The further prosperity of the Sino-Thai bilateral trade provides an opportunity for the development of multimodal transport between them. Since selecting a suitable multimodal transport route for the bilateral trade is important, this paper establishes a model based on Analytic Hierarchy Process (AHP) and Zero-One Goal Programming (ZOGP) for evaluating and selecting the multimodal transport route between China and Thailand by taking cost, time and risk as affecting factors into account. A numerical analysis by taking Thailand rubber export to China as an example has been done. The results show that the weight of transportation cost is the largest, followed by the transportation risk. By evaluating the seven typical routes from Songkhla (Thailand) to Qingdao (China), an optimal route is found, which proves the effectiveness and rationality of the modeling, and provides decision basis for decision makers.

ABSTRACT To investigate the distribution and behaviour of ocean vessels in the Arctic region and determine the impacts of their emissions, we examine vessel characteristics in conjunction with a series of Automatic Identification System (AIS) data between 2012 and 2016. These datasets, combined with a bottom-up model for estimating pollution emissions, enable us to analyse the level of pollution generated by vessels in the Arctic region. The results indicate that the movements of the vessels and their emissions increase in frequency and continue to do so unless clean energy or technologies are adopted. More than 80% of the emissions are found to be concentrated in the Norwegian and Barents Seas. Emissions from the Northern Sea Route are comparatively low and those from the Northwest Passage are similarly insignificant. Besides, an empirical analysis of the emissions in the Arctic region is carried out following the more restrictive International Maritime Organization (IMO)’s regulations on sulphur emissions that is implemented in 2020. This investigation supplements the literature analysing Arctic’s pollution emission inventory.

ABSTRACT Competition among academic institutions for students and Industry 4.0 have spurred institutions to actively improve undergraduates’ learning experiences and outcomes. The objectives of this research are to identify the quality dimensions of maritime studies programmes from students’ perspectives and examine their impacts on learning outcomes which include satisfaction, engagement, and academic performance. After reviewing the literature, six quality dimensions containing 29 measurement items were generated. An online survey was conducted on maritime students from Nanyang Technological University, Singapore. Thereafter, exploratory factor analysis and path analysis were used to analyse the survey data. The exploratory factor analysis produces a six-factor solution that confirms the proposed quality dimensions. Further, the quality dimension with the most impact on student satisfaction is (1) technology integration, followed by (2) industrial exposure, (3) learning and teaching environment, (4) industry-aligned & innovative curriculum, (5) faculty member competencies, and finally (6) supporting activities. In addition, student satisfaction positively influences engagement and academic performance. Further, engagement positively influences academic performance. The developed quality dimension model can serve as a measurement tool for maritime institutions to assess the quality of their programme and update their curriculums respectively to meet students’ expectations and learning outcomes.

ABSTRACT This paper aims to examine the main practices that shape sustainable port development in the context of Korean ports and generalize a typology of port–stakeholder decision framework for sustainable port development. First, the main practices of sustainable port development were examined through a comprehensive literature review and a holistic conceptual framework underpinned by sustainable development and stakeholder management theories. Semi-structured interviews were then conducted with 67 port managers in Korea. Lastly, FAHP was performed based on inputs from 18 port managers to analyze the priorities of the proposed sustainable port development practices. It was found that all proposed practices should be used for evaluating sustainable port development. It was also indicated that Optimized Operation Planning is the most important factor while Internal Environment Management is the least important factor perceived by Korean port managers. A typology of port–stakeholder framework for sustainable development was also generalized to assist port managers in making phased investment decisions. This research contributes to theory building by empirically identifying and validating the sustainable port development practices considering all three aspects of sustainability. It has also generalized a typology of port–stakeholder framework for sustainable development which can be used as a guideline for sustainable development decisions.

ABSTRACT Greenhouse gas emissions in the shipping industry have been a major challenge in the sustainability of international transportation. This paper studied shore power management for river shipping, which has become increasingly popular in some international transport networks. We discussed stakeholders’ incentives and concerns regarding shore power and found that vessel owners play one of the dominant roles in the wide implementation of shore power. Then, a mathematical model is developed to show the advantages of shore power by combining it with an analysis of the optimal oil inventory plan for vessels. When the plan of the oil inventory on vessels is well designed, using shore power could be more beneficial than oil even if the shore power has a higher price than the latter because using shore power can provide the vessel with more options to improve the oil inventory plan by reducing oil consumption during berthing and the number of refueling. Sensitivity analyses are conducted to obtain a better understanding of the impact of the parameters on the performance of shore power. Our policy suggestions and findings can shed lights on how to make incentive policies for a wider and easier implementation of shore power under international shipping.

Global trade nowadays faces significant challenges due to the pandemic, geopolitical conflicts, supply chain disruptions, technology innovations, and so on. In response to these challenges, the development of logistics systems continues to drive the recovery and growth of international trade. This leads to even more complex global supply chain networks, typically involving maritime transportation, inland waterways, road, air and rail transportation systems. This special issue aims to bring together recent theoretical and practical research on the development of logistics and maritime systems for global trade. The first article by Sun et al. studies two new shipping routes in response to the retreat of Artic Sea ice caused by global warming. The two new shipping routes, including the Northwest Passage and the Northern Sea Route can significantly shorten the global transportation distance, stimulate trade among countries in the northern hemisphere, and change the hub ports. In order to evaluate the change of hub ports, this study applies a Spatial Computable General Equilibrium (SCGE) by modeling both global seaborne trade behavior and global container flow distributions. The SCGE is calibrated by actual trade and port throughput data, and the results indicate that some southern hub ports will show a declining trend, as some potential hub locations will appear in the northern areas. The second article by Zhang et al. studies the design of a multimodal and multilayer inbound logistics system for the delivery of iron ore from suppliers to steel plants. With demand uncertainty taken into account the study proposes a two-stage nonlinear stochastic programming model to optimize the design of the logistics system. The model is then linearized and reformulated. A scenario-based decomposition algorithm is then developed to solve the model. The proposed model and solution algorithm are applied to a case study of a steel company in China, and numerical experiments are conducted to demonstrate their effectiveness. The third article by Kim et al. studies how to make efficient stowage plans for shipping liners with foldable containers and shift cost-sharing taken into account. Foldable containers have recently been used more and more in maritime transportation systems. On the one hand it brings opportunities for shipping liners to save vessel spaces, but on the other hand it complicates vessel stowage plans. To address such complications, this study proposes a mixed-integer programming model that incorporates foldable containers in stowage plans as well as shift cost-sharing in the redistribution of containers on vessels. Through computational experiments, it has been shown that by applying the newly proposed model, shipping liners can eliminate most unnecessary redistributions of containers on vessels, and that inevitable container redistribution costs can be shared fairly. The next four articles study terminal operations management for logistics and maritime

ABSTRACT Emissions from ships have negative effects on both humans and the environment, particularly in port areas. This paper develops a bottom-up activity-based model to compute emissions from container vessels within the boundaries of the port of Singapore. The input data is nearly 2 million Automatic Identification System (AIS) signals recording ship calls and various ship specifications. The paper analyses the container vessel segment by compiling a comprehensive emission profile by vessel size, port call time and carriers. This generates new insights in the dynamics and sources of ship emissions. The results show that the majority of emissions were produced by ship calls of shorter than 2 days, and 46% of the total emissions were produced by container feeder vessels as a result of Singapore port being a major international transhipment hub and the more frequent visits from such vessels. Our study also indicates stable distribution of emissions over the year, suggesting seasonality does not play a major role in container shipping operations.

ABSTRACT We investigate whether there are consistent misspecifications of volatility in the freight options markets that can be exploited in profitable trading strategies. We derive smooth forward freight rate curves from observed market prices and convert these to term structures of historical volatility for the Capesize, Panamax and Supramax segments of the drybulk shipping market. The differences between the historical and implied volatility term structures form the basis for executing option trading strategies. We find that there exist statistical arbitrage profits in the freight option markets, suggesting a degree of market inefficiency.
