  • Dynamic Vehicle Routing Problem with Cooperative Strategy in Disaster Relief   Order a copy of this article
    by Seyed Mohammad Gholami-Zanjani, Ruholla Jafari-Marandi, Mir Saman Pishvaee, Walid Klibi 
    Abstract: Many studies have focused on static vehicle routing problems (VRP) in which all information is known in advance. However, in recent years, the growth of technology has brought about a new range of problems, referred to as dynamic vehicle routing problems. In these problems, a part of the orders are received in advance before departure of vehicles from depots, but some new orders will come in after the vehicles departure. In both situations utilizing multiple vehicles and cooperative strategy can decrease costs. Although cooperative strategy has not received considerable attention in the literature, it could be a possibility in practice which can help reduce costs. Multiple vehicles in this strategy are allowed to travel and they can transfer goods between one another (from the main vehicle) when they meet in demand points so as to better satisfy the late demands. The benefits of such optimizations, which consider dynamic orders, are evaluated in case of emergencies far from the expected zones and the distribution centers. A mixed integer nonlinear mathematical model is proposed for multi-vehicle routing problem considering product transshipment between vehicles in dynamic situations. The objective function is to minimize the total cost of transportation as well as the number of lost sales. A robust genetic algorithm is then developed to deal with the complexity of the problem. The experimental results show that cooperative strategy is an attractive possibility to reduce unsatisfied late received demands and costs.

  • Analysis of risk factors influencing the safety of maritime container supply chains   Order a copy of this article
    by Zaili Yang, Chengpeng Wan, Xinping Yan, Di Zhang 
    Abstract: This paper aims to identify the major risk factors influencing the safety and security of maritime container supply chains (MCSCs) to aid the effective management of the associated risks. By doing so, the definition and classification of supply chain risks in a general context are first reviewed to provide a reference for the understanding and analysis of risk factors in MCSCs. A novel risk classification framework, incorporating a Delphi survey and a risk matrix approach, is proposed to identify the major risk factors of significant safety concerns from five perspectives, including society, natural environment, management, infrastructure and technology, and operations. As a result, different types of risk factors in MCSCs are identified through a systematic review of previous studies. Then, a Delphi expert survey is undertaken to explore the emerging hazards that have not yet been raised/studied in the literature. The survey is carried out by interviewing different groups of maritime stakeholders, who own the world leading commercial container fleets and container ports. Relevant data for the assessment of all identified risk factors are collected through a large-scale questionnaire survey, and the identified risk factors are quantitatively evaluated regarding their occurrence likelihood and consequence severity. This paper extends the risk analysis from the segment level (e.g. nodes and links) to a supply chain level, and realises the hazard identification and risk evaluation of different MCSC segments on the same plate so that they can be better understood and managed from a systematic perspective. The research results will provide useful insights for risk control and accident prevention, which is beneficial to different types of stakeholders involved in the shipping industry.

    by Xun Tong, Chris K.Y. Lo, Kee-hung Lai, T.C.E. Cheng 
    Abstract: Security management has become a topical issue in supply chain management (SCM) and operations and production management (OPM). Researchers are keen to address issues related to the prevention, mitigation, and recovery from security incidents and to the development of security management systems with cost efficiency consideration. This study presents a citation network analysis (CNA) of supply chain security (SCS) by analyzing 143 sample SCS articles. Specifically, we conduct a cluster analysis and a main path analysis to identify the research clusters in SCS literature and show knowledge transformation in SCS chronically. We identify four research clusters, which are (1) SCS Conceptualization and Application, (2) Security Management Systems, (3) Transportation Security, and (4) Terrorism, and the research gaps in each cluster are discussed in this review through an in-depth analysis of the articles in each cluster. This study helps scholars in SCM and OPM reveal the current trend in SCS management research and suggest potential research directions for future study in SCS.

  • A Tabu Search Approach to the Cargo Prioritization and Terminal Allocation Problem   Order a copy of this article
    by Jingjing Tong, Heather Nachtmann 
    Abstract: To mitigate inland waterway disruption impacts, we develop a tabu search (TS) approach to solve the cargo prioritization and terminal allocation problem (CPTAP) to minimize the total value loss of disrupted barge cargoes by offloading the cargoes to the land transportation modes. CPTAP is formulated as a nonlinear binary integer program, and problems of realistic size can be efficiently and effectively solved with an efficient heuristic approach. Given different neighborhood structures, multiple TS variants are attempted and compared. Solving CPTAP with our TS heuristic leads to the lowest cargo value loss and the shortest response time for the disrupted barges compared to a genetic algorithm approach and a na

  • Evaluation of Key Success Factors of Port-City Waterfront Development   Order a copy of this article
    by Kamonchanok Suthiwartnarueput, Paul Tae-Woo Lee, Krisana Visamitanan, Zaili Yang, Adolf K.Y. Ng 
    Abstract: This paper further investigates the key successful factors in waterfront port development (WPD). Consistent Fuzzy Preference Relation(CFPR), with the combination of the Preference Ranking Organization METHods for Enrichment Evaluation (PROMETHEE), is applied to six ports, namely Busan, Incheon Inner Port, Bangkok, Kaohsiung, Montreal and Liverpool. The latter technique is to evaluate performance of the WPD among the studied cases, while the former to draw KSFs of the selected ports. To draw meaningful comparison with the test results from Lee et al. (2014; 2016), this paper takes the same evaluation hierarchy in the questionnaire form in the previous studies. With a further validity of the previous findings in WPD studies, this paper does not only provide insight on exploring the generalization of KSFs in WPD in a longitude manner, but also contributes to the literature of WPD and port-city interplays.

  • Hedging Voyage Charter Rates on Illiquid Routes   Order a copy of this article
    by Andres G. Mirantes, Javier Poblacion, Gregorio Serna 
    Abstract: Freight prices are heterogeneous, and not all the routes have the same liquidity of spot or futures prices; therefore, sometimes there are problems related to one, or more, route hedges. In this paper, we develop a methodology to hedge the price risk of one route using other routes futures contracts. The main result of this paper is that we can hedge, with a great fit, the price risk of one route using other routes futures contracts. The hedging results obtained with our methodology outperform those obtained with standard simple regression procedures.

  • Quantitative evaluation of dual operational-environmental port performance in the Pearl River Delta   Order a copy of this article
    by Yifei Zhao, Qinghua Zhu, Ying Kou, Y.H. Venus Lun 
    Abstract: This study quantitatively evaluates the dual operational-environmental performance of the ports in the Pearl River Delta (PRD) region in China. Factor analysis is first applied to identify the common factors for comprehensively ranking the level of dual operational-environmental performance of each port. Environmental treatment, port conditions and development potential are identified as the common factors. The Port of Shenzhen is found to have the best performance in environmental treatment and development potential, while the Port of Guangzhou has the best fundamental conditions. Cluster analysis is then applied to compare the clusters of ports in the PRD region with and without green elements. It is found that small and medium-sized ports need to respond the call of Chinese government on provincial-level unified port platform to realize dual operational-environmental performance.

    by Sedat Baştuğ, Gamze Arabelen, Ceren Altuntas Vural, Durmus Ali Deveci 
    Abstract: The main aim of this study is to reveal the role and contribution of Industry 4.0 in the value chain of seaports. It first reviews the literature to identify value chain activities in the port industry. It then explores the Industry 4.0 applications utilized by ports through content analysis of the websites of ten (10) major innovative seaports. Seven main technological characteristics of Industry 4.0, namely digitalization, autonomization, transparency, mobility, modularization, network-collaboration and socializing, are used as the main research main categories. The findings show that ports engage with Industry 4.0 in four different modules namely port community systems, cyber-physical systems, internet of things and big data. These four modules enable ports to achieve cost leadership advantages in their quest for competitiveness. To achieve differentiation, on the other hand, they need to increase connectivity with customers and stakeholders through communication channels such as social media.

  • Integrated dedicated berth allocation and specialized handling equipment assignment in bulk ports   Order a copy of this article
    by Dolores Perez, Jian Gang Jin 
    Abstract: This paper addresses the berth allocation problem in bulk ports to enhance the operation efficiency of a bulk cargo terminal by integrating the berth allocation and handling equipment assignment decisions. Apart from deciding where to berth a bulk carrier, ports must allocate specialized equipment based on the type of cargo the vessel carries. The proposed mathematical optimization model considers a discrete berth layout and specific transfer rates of handling equipment such as conveyor, pipelines, grab cranes and cement facilities, with the objective of minimizing the overall port stay time. The developed optimization model was tested with data retrieved from real-world bulk ports and it can be efficiently solved by the commercial solver CPLEX. Results show that it successfully assigns vessels to dedicated berths evading congestion. Furthermore, the model properly allocates berth positions and specialized handling equipment reducing the overall turnaround time, thus improving customer service.

  • Shipbuilder country and second-hand price   Order a copy of this article
    by Floriano Pires Jr, Ricardo Fiasca, Luiz Assis 
    Abstract: The hypothesis that a shipbuilders country influences the second-hand price of ships is tacitly accepted by most market analysts and practitioners. This article presents an econometric analysis to test this hypothesis. The analysis is based on econometric modelling of second-hand ship prices. The regressors include ship deadweight, ship age, indexes of earnings and newbuilding prices, LIBOR, and dummy variables that represent the build country or region. Models specific for tankers, bulk carriers and containerships were estimated. The analysis has generally shown that the effect of a ships build country on the second-hand price may be statistically significant. Additionally, an assessment of the time evolution of this effect has been performed on bulk carriers built in Japan that were sold from 2003 to 2017. The results indicated some negative correlation between the market state and the price differentials associated with the build country.

  • An evaluation of alliance motives, shipping alliances, and alliance performance in Taiwan   Order a copy of this article
    by Chung-Shan Yang 
    Abstract: We introduce the transaction cost and market entry views as two critical motivations for shipping alliances and argue that shipping alliances increase alliance performance (i.e., improve oversupply, financial distress, and excessive competition). This study empirically evaluated the effects of transaction cost, market entry, and shipping alliances on alliance performance in a maritime shipping context. Data were collected from a survey of the Directory of the National Association of Shipping Agencies and Companies. A factor analysis was employed to identify the key dimensions, and a subsequent analysis was conducted using a structural equation model to test the research hypotheses. The findings show that shipping alliances act as a mediator variable between transaction cost, market entry, and alliance performance. The theoretical contributions and managerial implications are proposed to serve as a basis for a wider discussion of shipping alliances.

  • Modeling and quantifying the effects of trade facilitation on trade and international transport costs using the Logistics Performance Index   Order a copy of this article
    by Riadh Harizi 
    Abstract: In order to investigate and analyze the factors behind the promotion of international trade, we propose the Logistics Performance Index (LPI) as a way to measure the facilitation of international trade. We suggest modeling transportation costs and their impact on trade according to a gravity approach. The impact of the LPI appears to be robust to the preferred specification (basic or with fixed effects) and to the different implemented econometric techniques (OLS, Tobit, PMLT), to the extent that we always obtain a significantly positive impact of the LPI for both the importing and exporting countries. Our results reveal two major mechanisms: (i) an improvement of the logistics performance index leads first to a reduction in transportation costs, and (ii) it further results in the expansion of trade. Econometric tests also show that a 10% increase in the index positively affects the probability of trade occurring, with it increasing by 30% in the importing country and by 40% in the exporting one.

  • Modelling Inland Terminal Locations Based on Transport Cost Optimization   Order a copy of this article
    by Tomislav Rožić, Kristijan Rogić, Božidar Ivanković 
    Abstract: The position of inland terminal in transportation network depends on several elements. Selection of these elements has significant influence on its final location. This paper presents the quantitative method to define the optimal location of inland terminal in a node of railway network, primarily based on transportation cost savings. The key condition of the model is that all containers that are currently transported by road are to be transported primarily by rail from the seaport to the proposed location of the inland terminal. Onward transport to the destination can occur by road, rail or inland waterway where possible. The model was validated on a real network, where the first point of entry is the Port of Rijeka (seaport) in Croatia, and the possible location of inland terminal is in the Port of Rijeka hinterland (inside the Croatian borders). The application of the model on a real network has proven its usefulness, especially in the case when there is need for additional criteria in the decision process of determining the inland terminal location.

  • Economic Impacts and Significance of the Cruise Ports in the United States   Order a copy of this article
    by Grace Wang, Wen-Huei Chang, Yue Cui 
    Abstract: There are more than 50 federally authorized ports in the U.S. with presence of cruise ships, where the US Army Corps of Engineers (USACE) is responsible for construction, operations, and maintenance. However, federal budgetary funds are allocated mostly based on tonnages and commodities shipped rather than the number of passengers served. We aim to establish the economic impact platform to capture the complexity and the uniqueness of a cruise port in the value-added chain. From what comprises a cruise maritime cluster and to what extent core cruise business are integrated, the economic impact of a cruise port is much different from the existing literature considering only passenger consumption. A comprehensive model with port, cruise line operation, and the role of related business in the supporting industries is proposed. Through the simulation platform proposed, economic impacts on one the busiest cruise ports in the United States, Canaveral Harbor Florida, is calculated.

  • Risk in Port Logistics: Risk Classification and Mitigation Frameworks   Order a copy of this article
    by Kee-hung Lai, Markus Vejvar, Venus Y. H. Lun 
    Abstract: Ports are important nodes in maritime transportation networks. However, port managers face different types of risks in port operations which may disrupt cargo flows in the logistics chain. These risk factors are expected to increase in view of such global issues as climate change and geopolitical changes. An overview of risk classifications and mitigation strategies in port logistics can help academics and practitioners prepare for managing port logistics risks. This paper identifies and classifies risk in port logistics and proposes frameworks for managing risk and formulating mitigation strategies based on the two examples of the Ports of Rotterdam and Hong Kong. Our findings advance knowledge on the different risk factors with a practical step-by-step approach for addressing the risk in port logistics.

  • The impact of operational strategies on vessel handling times: a simulation approach   Order a copy of this article
    by María D. Gracia, Julio Mar-Ortiz, Rosa G. González-Ramírez 
    Abstract: This paper reports a study of the ship loading and discharging process at a container terminal. Our objective was to analyse the impact of different operational strategies on vessel handling times in order to derive managerial insights that can be used by terminal operators to manage this key performance indicator. As a basis for our study, a simulation model was implemented, validated, and verified to gain insight into the containers loading and discharging process. Four scenarios were constructed to resemble possible instances under which a vessel would operate at a Mexican container terminal, with the different operational strategies that were designed and evaluated for each scenario. An experimental framework was proposed, based on comparisons of scenarios and search experimentation, and employing a fractional factorial design to evaluate the impact of several factors on the vessel handling times. Our results emphasise that with an adequate design of the operation parameters, combined with the implementation of efficient stacking policies; it is possible to keep VHT under control. Conclusions and recommendations for further research are also discussed.

  • A statistical forecasting model applied to container throughput in a multi-port gateway system: the Barcelona-Tarragona-Valencia case   Order a copy of this article
    by Manel Grifoll 
    Abstract: This contribution investigates the container throughput flow in a multi-port gateway system: Barcelona-Tarragona-Valencia (BTV). First, the paper examines the recent dynamics of the total and transhipment flow showing a relevant shifting of traffic share from Barcelona to Valencia. A novel model based on a two-state Markov model in conjunction with a Monte Carlo experiments is implemented to estimate the predictions of annual growth in container throughput. Verification tests show how the predictions are reasonably good with error metrics similar to other methods based on timeseries analysis (trend projections and ARIMA). The strength of the method relies in the statistical nature of the predictions provided (i.e., mean and data dispersion). The method is considered suitable for short-term forecasting. The practical application of the method considers separately the import/export and transhipment container throughput, revealing a different dynamics in both container flows.

  • Development of a maritime safety management database using relational database approach   Order a copy of this article
    by Siyu Xu, Hao Hu 
    Abstract: Many types of maritime incident databases have been established that allow people to learn from past incidents and develop corresponding mitigation measures. However, our investigation of multiple international and national databases shows that most existing databases only record basic information regarding incidents in a single table. Lots of useful information is not included in the database (i.e., limited extension of the database). Meanwhile, some basic information is recorded tautologically (i.e., data redundancy). In this paper, two widely used databases are taken as examples, the Global Integrated Shipping Information System and the Lloyd's List Intelligence, to explain these common problems of existing databases. To overcome these limitations and improve the efficiency of data maintenance, this paper develops a relational maritime safety management database. The entity-relationship model is first used to depict the inter-related semantic information surrounding maritime incidents, and a relational database model is subsequently formed. Microsoft Access is employed to implement the proposed database, and a database application is also designed to demonstrate the utility of the database. Our preliminary study shows that the proposed database is implementable and has potential usage for both industry and academic research.

    by Lin Ma, Chun Jin, Yunfu Huo 
    Abstract: This paper focuses on the selection of e-commerce logistics service modes that is becoming more and more prominent as its importance. The current researches are mainly limited by using the empirical method but rarely considering the multi-oligopolies competition and comparison among modes. Four modes are modelled in this paper based on multi-oligopolies Cournot competition theory. The results show that the improvement of logistics service management and technological progress are the basis, the marginal service cost is the most important, then the transaction cost and the scale effect in the mode selection. When the logistics service ability is given, the mode of opened platform provides to online stores (PO) is an advantage strategy for e-commerce platform and common online stores. The mode of opened 3PL providers provide to online stores (TO) is an advantageous strategy with competitive price for opened platform and is more attractive to small online stores.

  • The Impact of Information Sharing on Installation Processes of Offshore Wind Farms – Process Modelling and Simulation Based Analysis
    by Thies Beinke, Moritz Quandt, Abderrahim Ait-Alla, Michael Freitag 
    Abstract: The installation of offshore wind energy turbines is accompanied by great challenges arising from the dynamic environment, which influences logistics processes. Communication plays a major role for cost-efficient installation processes, due to the coordination needed between different partners involved in the offshore wind energy supply chain. A detailed process analysis revealed the importance of shared information about weather conditions, storage capacities and vessel availabilities. By applying a simulation study, which evaluates eight Information Sharing scenarios, the influence of the following execution time-related performance measures is investigated: average time in manufacturer storage, average time in port, total installation time and average vessel usage time. As a result, the simulation study verifies that sharing information between supply chain partners can contribute to more efficient logistics processes. However, the achievable prediction accuracy and the interdependencies between the information items have a major influence on the quality of results.

  • Remote Interactive Platform for Matching Design of Ship Screw Propeller and Diesel Engine Based on Internet Plus   Order a copy of this article
    by Kun Yang, Biao Hu 
    Abstract: In order to meet the requirements of the remote ship propeller matching design, and can feed the measurement data to the offshore calculation model to guide the design of the ship propulsion system, this paper designed a screw propeller matching computing platform based on the Internet. The platform was built on the B/S architecture, combined with MATLAB and C# for mixed programming, and used Easyui plug-in set to design user interface. The open water characteristics of the ship were selected as the fundamental data of the whole process of matching calculation. The platform was tested by three parts: the preliminary matching, ultimate matching and cavitation checking. By comparison, the difference between calculated value and actual value is very small, which can meet the accuracy requirements. This platform can provide an engineering basis for the online working condition monitoring of the ship power system and the dynamic matching of the ship propeller in the "Internet plus" environment in future.

    Abstract: With the development of the international ocean shipping and the increase in the automatic identification systemreceiving equipment, the availability of ship trajectory data has shown explosive growth. To reduce the uncertainty in the application of sparse ship trajectory data in the open sea, this paper proposes the use of an ant colony algorithm based on node weights and edge weights for ship trajectory reconstruction. First, the extracted ship stop areas are used as the starting and ending marks of the ship's voyage, and the ship's trajectory is cut to form a plurality of consecutive voyages and stored in the prior knowledge base. Second, the navigational habits of the voyagers is attributed to the data mining problem based on the ship's trajectory point directed neighbourhood density map, and the density-weighted ant colony algorithm is used to extract the trajectory density centerline of each route. Finally, the matching degree is used to associate the single-voyage trajectory points with the corresponding centerline, and the trajectory reconstruction of the single-voyage segment is realized by the spatial transformation of the geometry of the centerline. In addition, in order to further experiment the proposed method for the reconstruction of trajectory in the large scale, this paper also uses the reconstructed trajectory to extract the distribution of ship traffic flow in the study area. The experimental results show that compared with the piecewise cubic spline interpolation method, the variance, standard deviation and mean of the proposed trajectory reconstruction method are improved by 96.18%, 80.47% and 85.10%, respectively. In summary, the proposed trajectory reconstruction method can reconstruct ship trajectories in open seas more accurately.

  • Risk Analysis of Petroleum Transportation using Fuzzy Rule-Based Bayesian Reasoning   Order a copy of this article
    by Ayman Alghanmi, Zaili Yang, Eddie Blanco-Davis 
    Abstract: Petroleum Transportation Systems (PTSs) play a critical role in the movement of crude oil from its production sites to end users. Such systems are complex because they often operate in a dynamic environment. Safe operations of the key components in PTSs such as port and shipping are vital for the success of the systems. Risk assessment is a powerful tool to ensure the safe transportation of crude oil. This paper applies a mathematical model to identify and evaluate the operational hazards associated with PTSs, by incorporating a Fuzzy Rule-Based (FRB) method with Bayesian Networks (BNs). Its novelty lies in the realisation of risk analysis and prioritisation of the hazards in PTSs when historical failure data is not available. This hybrid model is capable of assisting decision-makers in measuring and improving the PTSs safety, and dealing with the inherent uncertainties in risk data.

  • Solving inland container ship stowage planning problem on full route through a two-phase approach   Order a copy of this article
    by Jun Li, Yu Zhang, Lanbo Zheng 
    Abstract: Inland container ship emphasizes capacity utilization due to its limited capacity. Its stability is very sensitive to the stowage plan. The shipping line planners are under pressure to make efficient stowage plan on full route. This paper proposes adopts a two-phase approach to separate the problem into two planning levels: Multi-Port Master Bay Plan Problem (MP-MBPP) on full route and Slot Plan Problem (SPP) for each bay at each port. The mathematical models are proposed respectively for both sub-problems based on mixed integer programming. For each sub-problem, the Greedy Randomized Adaptive Search Procedure (GRASP) and the Heuristic Evolutionary Strategy Algorithm (HES) algorithm are proposed respectively. The Grey Entropy Parallel Analysis Method (GEPA) method is presented to guide HES in multi-objective optimization. Experimental results based on real-world scenarios are presented to show the efficacy of proposed algorithms and method.

  • Analysis of performance influence factors on shipboard drills to improve ship emergency preparedness at sea.   Order a copy of this article
    by Burcu Ozturk Tac, Emre Akyuz, Metin Celik 
    Abstract: Emergency preparedness is a critical aspect of ship management. It is required to establish strict procedures including drill and exercise programs to response emergency situations at any time. This study develops an approach to identify and quantify the influence factors to ship emergency preparedness demonstrated in drills on-board. A fuzzy DEMATEL (Decision Making Trial and Evaluation Laboratory) method is considered as a suitable method for the problem. As the DEMATEL method enables to identify and analyse the potential critical factors with respect to causal-effect relation, fuzzy sets tackle the uncertainty in decision-making. As a case study, the affecting factors to predefined steps (i.e. time of sounding the fire alarm) of an operational firefighting drill organization is analysed. The study is expected to contribute to the forthcoming studies on prediction of ship emergency preparedness level on-board ships.
    Keywords: ship emergency preparedness; firefighting drill; ship operation management.

  • A Holistic Sustainability Framework for Oil Terminals: The Case of China   Order a copy of this article
    by Xuemuge Wang, Shaofeng Liu, Jingjing Xu, Michael Roe 
    Abstract: This research provides a sustainability framework for the Chinese oil terminal sustainability performance evaluation in oil terminals operational and managerial conditions. Due to the lack of holistic oil terminal sustainability research in the existing literature and the increasing demand for sustainability pursuits, the developed sustainability framework is expected to be able to act as holistic guidance for port managers to systematically improve oil terminal sustainability performance by showing which indicators and groups should be considered. In the beginning, a rich amount of comprehensive existing Sustainability Performance Indicators from the literature are identified. Then, by the conduction of semi-structured interviews with 34 experts within the field, omitted practical or included unpractical indicators are added to / eliminated from the framework to finalise a holistic and practical Chinese oil terminal sustainability framework. After the thematic analysis of interview results, 14 categories and 65 indicators are identified for the practical holistic sustainability framework. Convincingly, this research emphases combining theories into practices via the validation and replenishment of the existing Sustainability Performance Indicators by experts to enhance the reliability and feasibility of the forwarded sustainability framework. As a result, this research contributes to the existing literature a holistic oil terminal sustainability framework, and for the first time assimilates the overproduction issue into terminal sustainability management.

  • Service recovery and customer satisfaction in container liner shipping industry An ordered LOGIT approach   Order a copy of this article
    by Enna Hirata 
    Abstract: This paper assesses the responsiveness of service recovery process to customer satisfaction in container liner shipping (CLS) industry. The research deals with real-world business events, conducted using a survey method, in which customers evaluate service recovery scenario and complete a questionnaire with respect to CLS carriers they had recently patronised. Estimated by ordered logit regression method, the results show that timeliness of communication is the most significant service recovery attribute. It also finds that customers in different segments prefer receiving recovery resources in different ways; effective service recovery could help improve customer satisfaction and service recovery paradox exists in the industry. The findings contribute to the understanding of theoretical explanation of service recovery attributes and provide managers with useful guidelines for establishing effective recovery process. Unlike other research, this paper draws on data from actual customers in CLS industry and therefore benefits from increased external validity.

  • Principles in Practice: An Examination of Cascading   Order a copy of this article
    by Trevor D. Heaver 
    Abstract: This article examines the concept of cascading of container ships and the relationship of cascading to fleet management. It is written to apply two of the legacies that Richard Goss left to the maritime community: discussion of maritime topics through conferences and journals; and the application of basic economic principles to shipping. Richard had a special interest in the many aspects of the economics of ship size. The increases in the size of container vessels on the East Asia to Northwest Europe route since 2000 gives rise to the type of concept that Richard might have examined; the cascading of ships. The concept of cascading is examined in the light of basic aspects of the economics of ships size. It is shown that cascading does not take place simply because of the displacement of large vessels from certain routes but is dependent on the presence of various dynamic forces affecting the fleet deployment decisions of lines. Cascading is shown to be a process guided by management decisions affected by financial as well as economic considerations. It is not as simple as water running downhill.
    Keywords: Ship cascading; container vessel deployment; optimal ship size.

  • Goss and ensuing research in shipping and port   Order a copy of this article
    by Young-Tae Chang, Paul Tae-Woo Lee 
    Abstract: The late Professor Richard Goss published twenty-five journal papers and edited two books and three monographs during his academic life of three decades. This paper revisits his work and examines whether ensuing research in shipping and port areas have been aligned with his academic thought and ideology. To this end, we first review his work to identify key concepts, theories and methodologies underlying his academic reasoning. Moreover, we utilize Chang et al. (2018)s research outcomes to examine whether his theoretical propositions are still valid today in terms of both theory and empirical findings. We discuss whether there is a foregone conclusion on Goss major themes and propositions or requires further empirical testing, and whether there exists the possibility to develop new theories and hypotheses. Based on our findings, we suggest future research directions in the shipping and port sectors.

  • International port investment of Chinese port-related companies   Order a copy of this article
    by Weiwei Huo, Shu-Ling Chen, Wei Zhang, Kevin X. Li 
    Abstract: The devolution of Chinese port governance since the 1990s has resulted in not only private sectors involvement in Chinese port investment and development but also allowing local port groups and terminal operators to implement international strategies to expand their business. This paper overviews the current implementation on international port investment of these two types of Chinese port-related companies. By analysing 39 international port investment cases, this paper finds the Belt and Road Initiative (BRI) may promote China's investment in foreign ports. In addition, four main investment modalities are adopted i.e. acquisition, joint venture, concession and build-operate-transfer (BOT). The companies mainly form a partnership for investment, and some of the investment projects involve an integration of the development of ports, industrial parks and cities. Of notice is that some investment projects are through a public-private partnership (PPP) model, i.e. Chinese companies as private entities and public sectors in the host countries.

  • Port Policy: Are The Goss Principles Still Relevant Today?   Order a copy of this article
    by Mary R. Brooks, Sheila Farrell 
    Abstract: In 1990 Richard O. Goss wrote four seminal articles about the economic principles underlying port policies, which were published in Maritime Policy and Management under the title Economic Policies and Seaports. These explored the economic functions of seaports, the diversity of port institutions, the need for port authorities, and the strategies that ports might adopt to promote port efficiencies. Economic principles included the existence of seaports for the benefit of traders, the use of competition to maximise public welfare, the customisation of port institutions to meet local circumstances, and the need to involve all levels of government in seaport governance. This paper looks at the relevance of these principles today, and asks what further research is needed to fully understand that relevance.
