A Holistic Sustainability Framework for Oil Terminals: The Case of China
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.
Keywords: Sustainability Framework; Sustainable Indicators; Oil Terminal; Port Overproduction.
Integrated dedicated berth allocation and specialized handling equipment assignment in bulk ports
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.
Keywords: bulk port; berth allocation; handling equipment assignment; shipping logistics.
Service recovery and customer satisfaction in container liner shipping industry An ordered LOGIT approach
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.

Risk in Port Logistics: Risk Classification and Mitigation Frameworks
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.
Keywords: port operations; risk classification; risk management; maritime logistics; continuous improvement.
Finding the Optimal Order of Priority for Dry Port Construction: Case Study in the North of Vietnam
by Viet Linh Dang, Gi-Tae Yeo
Abstract: The development of the Vietnam dry port system is facing many difficulties, especially in matters of calling for investment as well as synchronization in developing transport infrastructure, such as between rail systems and dry port networks. The purpose of this study is to apply multiple-criteria decision analysis (MCDA) to investigate the determinants in prior implementations of dry port construction, as well as find the order of priority for dry port construction in Northern Vietnam. The results indicate that the possibility of transportation cost reduction is the most important factor, followed by the accessibility to highway road infrastructure and to seaports. Phu Dong dry port is indicated as the first port that should be invested in, thanks to its superiority in terms of geography, its ability to connect with the means of transportation as well as other factors, followed by the dry ports of Huong Canh, Lang Son, and Cao Bang.
Keywords: Dry port; MCDA; Fuzzy Topsis; Fuzzy Delphi; Optimal Order; Vietnam.

Coordination mechanism framework for container dwelling time reduction
by Femi Yulianti, Senator Nur Bahagia, Andi Cakravastia, Rajesri Govindaraju
Abstract: Dwelling time contributed 36.3% to the total time of land transportation in 2017 and is one of the commercial instruments to attract cargo and generate revenue. The government of Indonesia has attempted to reduce dwelling time by improving infrastructure and reforming bureaucracy but so far has paid little attention to straightening out coordination mechanisms between actors. Few studies have been conducted on port management integrated planning and control of all seaport areas and on coordination mechanisms related to dwelling time. This paper seeks to fill this gap with the question: How can coordination mechanisms between actors be conducted to reduce dwelling time? For answering this question, a coordination framework was built as the basis for the development of three coordination mechanism models.

Evolution and container traffic prediction of Yangtze River Delta multi-port system (2001-2017)
by Hongxiang Feng, Manel Grifoll, Pengjun Zheng
Abstract: Yangtze River Delta (YRD) region is a port agglomeration with the densest port distribution and highest throughput in China. Since 2003, three mega provincial port groups: Shanghai International Port (Group) CO., LTD. (SIPG), Zhejiang Province Seaport Investment & Operation Group Co. (ZPSIOG) and Jiangsu Port Group Co., Ltd. (JPG) formed in YRD multi-port system. Firstly, this contribution investigates the latest concentration tendency of YRD multi-port system with Concentration-Ratio, Herfindahl-Hirschman-Index and Shift-Share-Analysis. Results show that ZPSIOG is the major winner; SIPG is losing its oligopoly since 2012; SIPG, ZPSIOG and JPG are reaching a tripartite equilibrium in market share. Secondly, the contribution uses ARIMA model, linear regression model and GM (1, 1) model to forecast container throughput of SIPG, ZPSIOG, JPG and YRD. By mean absolute percent error (MAPE) criteria, all models have good or reasonable performance, ARIMA model obtains the best performance with MAPE of 2.37%, 2.41% and 6.54% when time series seem linear, however does not have excellent performance (MAPE is 14.26%) when time series is non-linear. Finally, we compare the indirect and direct method to forecast the YRD container throughput. In this case, the MAPE decreases from 6.54% to 3.85% respectively using the ARIMA model, which supports the out-performance of indirect forecast method. The combination of the analysis of the concentration index and forecasting methods has allowed to gain insight in the evolution and prospects of YRD container multi-port system.

International intermodal container shipping network in South Asia: Modelling and policy simulations
by Ryuichi Shibasaki, Tomoya Kawasaki
Abstract: This paper focuses on the international intermodal container cargo shipping network in South Asia. A two-layered network assignment model of international container cargo is applied to this region, for simulating the impact of policies designed to increase the level of international logistics infrastructure. The first simulation, which focuses on the improvements of the road and rail networks around the largest port in this region (Jawaharlal Nehru Port Trust, or JNPT), reveals that Indian west coast ports are very competitive in acquiring cargo both originating from and destined to Delhi. More importantly, these west coast ports face critical capacity constraints for hinterland shipping around JNPT. The second simulation estimates the effect of the recommencement of the international ferry connecting South India and Sri Lanka and suggests that the reduction of cross-border barriers and improving connected rail services are essential for promoting the international ferry service.
Keywords: intermodal transport; global maritime container shipping; network assignment; South Asia; logistics policy simulation.
Solving the Empty Container Problem using Double-Container Trucks to Reduce Vehicle Miles
by Santiago Carvajal, Maged Dessouky
Abstract: This paper proposes a mathematical model for the empty container reuse problem using double-container trucks. The model discretizes time and makes sure demand is met. Several model properties are presented, along with two heuristics that allow the model to be solved. By solving the empty container reuse problem, truck miles can be reduced since less truck trips are needed to satisfy the demand. Furthermore, since double-container trucks can deliver two containers per truck trip, the amount of trucks needed to satisfy the demand is decreased even more, further reducing truck miles. This will in turn make the system more environmental friendly. The model is then tested using the data from the Ports of Los Angeles and Long Beach, and on randomized data sets.

Green Port Performance evaluation under uncertainty: A multiple attribute group decision analysis
by Dan Zhao, Tiantian Bao, Kevin Cullinane, Yuhong Wang
Abstract: This paper aims to assess the performance of a port within the context of its supply chain on the basis of integrating a five-dimensional balanced scorecard with green performance criteria. A multiple attribute group decision making (MAGDM) approach is proposed which encompasses both intuitionistic fuzzy set theory and evidence theory in order to properly represent and aggregate the uncertain information which prevails within any process of such an evaluation. With an empirical application, the evaluation results provide effectively not only the ranking order of all alternative port enterprises, but also the strengths and weaknesses of each one, at the detailed level of individual performance attributes.

Information Sources Used By Charterers to Select Shipowners
by Sedat Bastug, Durmus Ali Deveci
Abstract: This study aims to identify the information search behaviour of charterers in selecting shipowners within a business-to-business framework. It focuses on charterers information sources and how different factors (individual, organizational, and purchase-related) affect the information search since this construct is a major component of comprehensive theories of organizational buying behaviour. Understanding the buying behaviour of charterers also helps marketers to increase customer satisfaction. The analysis is based on questionnaire responses from 141 firms that have recently chartered vessels. From a principal components analysis, the study identified eight sets of information sources, of which impersonal, emails and reference-based information were the most important. The results show that the business-to-business information sources used by ship charterers vary significantly according to organization size, centralization, type of purchase, purchase complexity and experience. Further analyses revealed a significant relationship between these factors and business-to-business information sources, specifically between the importance of the purchase, perceived risk, formalization, standardization, personal stake, specialization, and use of information resources. Finally, the study revealed a significant relationship between business-to-business information sources and customer satisfaction.
Keywords: Information Sources; Ship Chartering; Business to Business services; Industrial Buying.
Emission Accounting of Shipping Activities In the Era of Big Data
by Yuwei Yin, Jasmine Siu Lee Lam, Nguyen Khoi Tran
Abstract: Maritime transportation has generated a considerable amount of emissions and affected the global atmospheric environment. A key step of effective emission control is to construct reliable models of emission accounting. In recent years, there has been a major innovation in emission accounting, the application of big data, especially the data extracted from Automatic Identification System (AIS). In this paper, a dynamic and comprehensive analysis is developed to depict how emission accounting models have been evolved in this era of big data. In the perspective-based review, we thoroughly investigate the geographical coverage and pollutant types involved in the existing emission studies. In the process-based review, this paper establishes a solid knowledge framework of the two basic modelling concepts: top-down and bottom-up approaches. Furthermore, updated emission modelling methodologies and high resolute data sources are introduced. But the latest models are still subject to various sources of uncertainties. Hence, this paper identifies such unsolved problems and sets up a future research agenda.

The Effectiveness of Freight Costs on Trade Potentials Between China and European Union, Middle East, North African Countries Under China-Pakistan Corridor
by Osman Ghanem
Abstract: The study tries to estimate the trade potentials might be raised by comparing the current maritime route of one belt one road initiative and new maritime route in particular with the China-Pakistan corridor as a result of the changing freight costs, shipping period and distance between European Union (EU), Middle East, North African countries (MENA) and China. To estimate trade potentials, qualitative and descriptive statistical methods will be used to compare the real and predicted trade. The results suggest that China and the European Union (EU), Middle East and North African countries (MENA) can increase trade potentials and show that average predicted freight costs, shipping period and distance between china and European Union (EU) are decreased by $1545, 16.3 days and 10084 km respectively, and the average predicted freight costs, shipping period and distance between china and Middle East and North Africa (MENA) are decreased by $1695, 17.2 days and 10477 km respectively.

Economic Route Selection under the Integrated Operation Mode: Case Study of China Railway Express in Zhengzhou
by Xuefeng Wang, Yangyang Gu, Jiawei Ge, Liming Sun
Abstract: As a derivative and symbol of the Belt & Road Initiative (BRI), local governments in China raced to launch block trains to Europe, so called the China Railway Express (CR Express), isolating the economic potential of Euroasia rail transportation. From a logistic integration perspective, this paper establishes a multi-objective optimization model to find the optimal economical route by improving traditional route selection model, where the influence of the transportation mode and route is considered comprehensively. The genetic algorithm is applied to encode and solve the model. A case study is conducted to evaluate the economic benefit of various modes and route choices from Chinas cities to Lodz in Europe via Alataw. The findings show that the performance of an integrated operation in Zhengzhou is better than that of isolated operation. Compared with the isolated operations in various places, overall logistics time of integrated operation in Zhengzhou decreased by 7.14%, while the overall container logistics cost per unit decreased by 13.64%.

A Methodology to Classify Interventions in Ports Demand Series Changes Applyed to Brazilian Ports
by Francisco Gildemir Ferreira Da Silva
Abstract: The institutional, commercial and economic structure in Brazil has changed so far. In recent decades, Brazilian ports have changed operations or infrastructure through government intervention or exogenous disruption. In addition, Brazilian ports suffered some impacts, essentially, on the dynamics of port demands. The assumptions that economic series follow trends that are interrupted by external or intended interventions are very fruitful today. Some empirical approaches to measure the break point or magnitude of the breakdown in an economic series have been proposed by some economists. Notably the analysis of time series interventions was used in this work. Methodologically, the intervention was classified by measuring magnitude, direction and signal via univariate time series models. Following, the common characteristics of each intervention were compared, summarizing the common characteristics of the interventions. The proposal is important for political decision makers, particularly in a regulated market such as the Brazilian port. Classification can guide models of port demands for policy making to increase port efficiency, making ports more operationally effective. Method results can be used to select and use dummies in policy evaluation, such as increased infrastructure investment or protection of the port backwater area.
Keywords: Intervention Impacts Technique; Port Demand; Time Series Analysis.
A fuzzy AHP approach to evaluating differences between ocean container carriers and their customers
by Ayfer ERGIN
Abstract: The study has investigated ocean container carrier selection criteria in order to determine the differences and similarities between carriers and their customers in the Turkish market. In application, four separate groups have used: carriers, freight forwarders, shippers, and consignees. For the first time, differences in perspective between carriers and their customers are studied in Turkey, eliminating the gap in knowledge about this market. It is also the first study to utilize fuzzy Analytical Hierarchy Process (AHP) method to examine the differences in perceptions between ocean container carriers, freight forwarders, shippers, and consignees. This study contributes to the literature by employing both a new region and an unused method. The studys findings are that the most important sub-criterion for carriers and freight forwarders was low freight; meanwhile, the most important criterion for shippers was determined to be equipment availability. The most important sub-criterion of consignees was on-time notification of the customer.
Keywords: ocean container carriers; freight forwarders; shippers; consignees; fuzzy Analytical Hierarchy Process (AHP); Turkish liner shipping market.

Analysis of the Effect of Cruise Service Supply Chain Network Properties on Economic Profits
by Ling SUN, Wei Liu, Hanwen Zhang, Yan Jin, Gaoqiang Zhuo
Abstract: The cruise service supply chain (CSSC) is an integrated supply chain dominated by the cruise tourism service. It consists of a series of demand service providers, such as food, accommodation, transportation, travel, shopping, and entertainment. Based on social network theory, we outline the network properties of CSSCs. Using game theory models, we compute the profit distribution in a simplified version of the CSSC network. After studying different cooperation strategies among network members, we find that the overall network profit and profit distribution change with the network properties. When the network range and scale are fixed, the overall profit of the network increases with the relationship persistence, relationship strength, and cooperation between network members, while it decreases when there is top-down exploitation among network members. After evolving rules of the network structure, this paper This paper further refine the research based on the proposed growth path of CSSC, which is exactly from the centralized network to the distributed network and finally to the interconnection network. It is consistent with the decentralized trend of the block chain. Eventually this paper provides recommendations for the development mechanism of each CSSC network growth stage and for enhancing cooperation among network members.

Model and Algorithm for Vessel Scheduling Optimization through the Compound Channel with the Consideration of Tide Height
by Bin Zhang, Zhongyi Zheng
Abstract: To optimize vessel scheduling passing a compound channel with the water depth influenced by the periodic tide, this study establishes the vessel scheduling model through a typical tidal compound channel. In addition, based on the actual tidal data of the channel, a tide height computation function varying with time is obtained. Then a designed genetic algorithm (GA) is utilized to verify the model by the actual vessels' data through the Tianjin port fairway. The test experiment shows that the organization efficiency is better than other methods, including larger draft vessels first (LDF), First Come First Served (FCFS), random scheduling (RS) and manual scheduling. It can take full advantage of the high tide and improve the vessel scheduling efficiency of a compound channel. With minor alterations, the proposed model and designed algorithm can also serve for vessel traffic organization in other compound channels affected by tide water as well.
Keywords: compound tidal channel; tide height computation; optimization; vessel scheduling model; genetic algorithm.
On the Application of Uncertain Three-player Two-stage Game to the Competition among Shipping Alliances
by Thi Minh Hoang Do, Gyei-Kark Park, Kyoung-Hoon Choi, Xiangfeng Yang
Abstract: The financial crisis in 2008 has had a negative impact across all economic sectors, especially the shipping industry. Consequences of which include low freight rate, decreasing demand, overcapacity, historical low profit and even bankruptcy. Most of the top container lines have formed strategic alliances in order to strengthen their market coverage to avoid collapse; however, the fierce competition among such powerful carrier groups and group members is becoming a major concern. The purpose of this paper is to examine the competition from a pricing perspective and capacity expansion among the recently established alliances namely 2M+H, The Alliance and Ocean Alliance. An uncertain competition game model is built using game theory and uncertainty theory and the Nash equilibrium prices and expansion decisions of the three players are found accordingly. The ideas from experts in the field were employed to measure the uncertain future container demand and real data were used to validate the game model. The results from the research suggest that the forecasted container growth rate in Transpacific trade route is 2.65% in the next five-year period. Such a modest demand growth rate, low vessel utilization, high idle ship expenses and high investment cost discourage all alliances from investing in new ships at the same time to prevent further financial loss. Therefore, it is recommended that the number of new ship orders should be reduced at this moment in time and alliances strategic actions should be made to rebalance the shipping industry.

Simulation of Truck Arrivals at Container Terminal Based on the Interactive Truck Appointment System
by Qianqian Shao, Mingxia Huang, Siqi Zhang, Yunfeng Zhang
Abstract: Truck appointment system (TAS) is used to regulate the number of trucks that can enter the terminal. However, because of the limited number of quotas, TAS is incompetent to fully meet all requirements of time window for individual truckers. In order to avoid the limitation of TAS, a simulation-based truck appointment mechanism named interactive appointment system (IAS) was proposed with the purpose of balancing truck arrival peak and reducing truck turnaround time. IAS allows the trucker to get the estimated truck turnaround time over his preferred arrival time interval when making an appointment application. This can assist him to choose a reasonable appointment arrival time. Moreover, a discrete event simulation model was formulated to estimate truck turnaround time, through describing the tri-stage queuing system (gate-parking lot-yard) of terminals, with considering the interference of block occupying brought by ship discharging/loading operations. Results of a series of experiments demonstrate the effectiveness and robustness of IAS on alleviating congestion inside/outside terminal and decreasing truck turnaround time. In addition, how the parking quantity of parking lot influences the efficiency of terminal queuing system was also discussed in this study.
Keywords: container terminal; container logistics; truck appointment system; terminal parking lot; terminal congestion; truck arrival time; truck arrival peak; simulation modelling; queuing model; turnaround time.
Container barge (un)reliability in seaports: A company case study at the port of Antwerp
by Virzhiniia Oganesian, Christa Sys, Thierry Vanelslander, Edwin Van Hassel
Abstract: Inland waterways and ports play an important role in the entire transport system in the Hamburg Le Havre range, and for the seaports of Antwerp and Rotterdam in particular. The high proportion of inland navigation for both ports can be explained by reasons such as an extensive network along with a safe, reliable, sustainable and cost efficient transport. However, despite all these advantages, container barge transportation still faces certain challenges.
A major challenge relates to the unreliability of barge handling in large seaports, affecting overall performance of barge services essentially. This research shows that barge congestion exists, and it examines the causes of the observed phenomena. Next, it also provides an overview of solutions that are being developed in the port of Antwerp to improve and optimize container barge handling. Last, a case study is developed for a company that is located in the near proximity of the port of Antwerp, where the impact of barge handling unreliability is analysed.

Time Series Forecasting of Domestic Shipping Market: Comparison of Sarimax, Ann-Based Models and Sarimax_Ann Hybrid Model
by Cemile Solak Fiskin, Ozgu Turgut, Sjur Westgaard, A. Güldem Cerit
Abstract: Seaborne transport forecasting has attracted substantial interest over the years because of providing a useful policy tool for decision-makers. Although various forecasting methods have been widely studied, there is still broad debate on accurate forecasting models and preprocessing. The current paper aims to point out these issues, as well as to establish the forecasting model of the domestic cargo volumes using SARIMAX, MLP, LSTM and NARX and SARIMAX-ANN hybrid models. Based on the domestic cargo volumes of Turkey, findings suggest that SARIMA-MLP models can be considered as an appropriate alternative, at least for time series forecasting of shipping. Pre-processed data provides a significant improvement over those obtained with unpreprocessed data, with the accuracy of the models found to be significantly boosted with the Fourier term of decomposition. The results indicate that SARIMAX-MLP, with a mean absolute percentage error (MAPE) of 4.81, outperforms the closest models of SARIMAX, with a MAPE of 6.14 and LSTM with Fourier decomposition with a MAPE of 6.52. Findings have implications for shipping policymakers to plan infrastructure development, and useful for shipowners in accurately formulating shipping demand.

A simulated annealing-based approach for a real case study of vehicle routing problem with a heterogeneous fleet and time windows
by Jose Bernal, John Wilmer Escobar, Rodrigo Linfati
Abstract: We propose a meta-heuristic algorithm for addressing a real case of vehicle routing problem with a heterogeneous fleet and time windows. Our proposal consists of generating an initial feasible solution using the solution of a travelling salesman problem and, subsequently, refining it through simulated annealing. In this work, we evaluate the suitability of our development to planning the distribution of a regional distribution center of a food company to customers within the urban perimeter of Cali, Colombia. Following the companys customer satisfaction goals, our primary aim is to route to reach a service level of 95% while reducing operational costs. Our results on our real case study show that our meta-heuristic algorithm finds better routes than current ones, in terms of costs and service levels, in a relatively short time.
Keywords: Vehicle routing; heterogeneous fleet; time windows; meta-heuristic; simulated annealing.
Nash Bargaining of Transportation Rates with Flow Imbalances
by Marcos Singer, Ignacio Pardo, Ricardo Sánchez
Abstract: Consider two points, A and B, which trade products with a flow imbalance. We postulate that shippers at A face an implicit negotiation with the shippers at B regarding who must bear the cost of a vehicle traveling back and forth. Following the Nash bargaining model, we deduce that the ratio (freight rate A-to-B) / (freight rate B-to-A) changes linearly with the ratio (flow B-to-A) / (flow A-to-B). We validate our model with evidence from previous publications and with quarterly data from the Transatlantic, Transpacific and Europe-Asia maritime routes from 2003 to 2012.

Firms Operational and Logistics Characteristics and Realisation of Business Analytics Benefits: Evidence from Stock Markets
by L. M. Daphne Yiu, Andy C. L. Yeung, Hugo K. S. Lam, T. C. E. Cheng
Abstract: The idea of big data provides practitioners in the logistics industry with valuable opportunities to improve their operational efficiency and economic performance. In fact, business analytics techniques are increasingly being used in international logistics, shipping, and supply chain management. We examine the impact of business intelligence (BI) system adoption on firms market value and the influences of the operating characteristics and contexts of firms. Specifically, we examine whether the impacts of BI adoption is contingent on industry competitiveness, firms operating cycle, and industry munificence. Using the event study methodology, we analyse 272 manufacturing firms in the United States that adopted BI systems from 2005 to 2014. We find that BI adoption does not have an immediate impact on firms stock returns, but such impact is significantly enhanced for firms in highly competitive industries, and those with short operating cycles and high industry munificence, i.e., high-growth industries, suggesting that firms in fast-changing dynamic environments find BI systems much more useful.
Keywords: business intelligence systems; stock returns; industry competitiveness; operating cycle; industry munificence.
DESIGN FOR SUSTAINABLE SHIP DISMANTLING BASED ON TRIPLE BOTTOM LINE PERSPECTIVE
by Yucel Ozturkoglu, Yigit Kazancoglu, Yesim Deniz Ozkan Ozen
Abstract: While ship dismantling is an important economic sector, especially for developing countries, it has severe impacts on human health and the environment. Therefore, it is essential to adopt sustainable approaches to ship dismantling. Considering the entire life cycle of ships, the sustainability of dismantling activities can be affected by the initial ship design phase. This study therefore investigates the relationship between ship design criteria and triple bottom line sustainability dimensions: human, environment and business. A multi-criteria decision-making method, fuzzy TISM, is used to determine the distinct causal relationships between design criteria and effects on humans, the environment and business. This contributes to the literature regarding designing for sustainable ship dismantling. The study recommendations to management, covering the training of designers, work design, material selection, life cycle assessment, standardization of parts and modular design, top management support and governmental support for design for sustainable ship dismantling practices.

Abstract: We develop an evaluation model for the 15 Chinese ports, intended to be the eastern end of Chinas Belt and Road Initiative (BRI). Our aim is to determine those ports respective roles within BRI, so as to also ensure the latters sustainable development. To do this, we introduce the concept of sustainable development capability. We employ principal component analysis and analytic hierarchy process to build an assessment system which evaluates the cooperative sustainability of these ports on the basis of four dimensions: capacity of port operations; (ambient) economic conditions; environmental factors; and human intellect and technology (HIT). Sensitivity- and cluster analysis are used, to classify the 15 ports into four categories (or respective roles): international hub ports; regional hub ports; node ports; and regional gate ports. Our results single out Shanghai as the only international hub port. The ports of Tianjin, Guangzhou, Shenzhen, Dalian, Ningbo and Qingdao come out as regional hubs. The remaining ports are deemed to be able to serve as nodes or regional gate ports, connecting China to MSR. It is hoped that the port system we present and assess here will provide guidance to ports and countries, especially in Europe, leading to the right alliances and partnership agreements among ports, that could turn the Maritime Silk Road into an efficient global transportation system.

Key antecedents to achieving flexibility in maritime logistics industry: empirical evidence from China
by Xiaohui Jia, Zhongzhen Yang
Abstract: The aim of this paper is to recognise key antecedents which are absolutely necessary to achieving flexibility in maritime logistics industry. Methodologically, personal interview and a three-round Delphi survey are used for data collection. We test the key antecedents and derive a ranking of the importance of these antecedents. These findings allowed us to build a model of key antecedents to flexibility in the industry. The canonical correlation analysis reveals that the interrelationships among sets of key antecedents are positive and strong. The results offer managerial insights for companies in the industry to improve their responsibility to uncertainty.

Shipbuilder country and second-hand price
by Floriano C.M. Pires Junior, Ricardo Brito Fiasca, Luiz Felipe Assis
Abstract: The hypothesis that a shipbuilder's 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 ship's 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.
Keywords: second-hand ship price; shipbuilding country and ship value; shipping econometrics; shipping markets; ship price modelling; second-hand ship price influencers.
An evaluation of alliance motives, shipping alliances, and alliance performance in Taiwan
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.
Keywords: shipping alliances; transaction cost; market entry; alliance performance.
Modelling and quantifying the effects of trade facilitation on trade and international transport costs using the logistics performance index
by Harizi Riadh
Abstract: In order to investigate and analyse 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 modelling 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 and 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: 1) an improvement of the logistics performance index leads first to a reduction in transportation costs; 2) 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 optimisation
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 USA
by Grace W.Y. Wang, Wen-Huei Chang, Yue Cui
Abstract: There are more than 50 federally authorised ports in the USA that feature cruise ship operations, 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 an economic impact platform to capture the complexity and 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 is proposed that analyses cruise ports, cruise line operations, and the role of related business in the supporting industries. Through the use of the proposed simulation platform, economic impacts are calculated for one of the busiest cruise ports in the USA, Canaveral Harbor Florida.
Keywords: cruise; economic impacts; cruise operation.

Evaluation of the tram intelligent system management by an analysis of its key performance indicators for an optimal mixed traffic control in Algeria
by Mouloud KHELF, Salim Boukebbab, Neila Bhouri
Abstract: Evaluating the tram intelligent system management by analyzing its keys’ performance indicators is the main target of this paper. A deep analysis of its theoretical and real performance is done, to evaluate the tram’s regularity and the actual timetable. The second important objective is to show how the tram’s performance can influence the traffic control system. To optimize it, an optimal cycle time applying the “Webster” method is combined with the optimal tram timetable at the same time. The results indicate that the tram is unwell operated, the offered capacity is higher than the real demand, besides, the theoretical tram performance that is not respected. Therefore, the traffic jam has increased in common intersections. The suggested solutions, prove the possibility to reduce the traffic congestion yet well refining the management of the mixed traffic systems, simultaneously, without using extra infrastructures or technologies. All this exhibits the value of this paper.
Keywords: tram intelligent system, key performance indicators, traffic control, timetable, intersections, traffic congestion.

Asset Shortages and Economic Operating System Based on Two-stage Least-squares Regression
by Yang Yang, Shuwen Liu
Abstract: The rapid development of information technology and e-business has promoted financial development but has not addressed chronic asset shortages. Asset shortages are an important factor that affects enterprise operating systems and consequently influences economic growth. Using China’s provincial panel data from 2001 to 2014 as sample, we use the overlapping generations model, fixed effect model, two-stage least-squares regression, and quantile regression model to explore the impact of asset shortages on economic growth. Empirical results show that asset shortages have been a perennial problem in China’s provinces, thus having a significantly positive correlation with economic growth. In addition, the moderating effect of asset shortages positively influences the relationship between financial development and economic growth. These findings bear the practical implication that the government should develop information technology to increase the effective supply of sound assets.

Design of Reverse Logistics System for B2C E-commerce Based on Management Logic of Internet of Things
by Li WEI, Zhiqiang MA, Ningning LIU
Abstract: In recent years, the B2C e-commerce industry has developed at a surprising high speed in China, but the return rate of e-commerce is also increasing at the same speed, which makes the demand of reverse logistics of B2C e-commerce difficult to meet under the traditional logistics mode. To solve this problem, based on the logic of Internet of Things management, this paper designs and constructs the collaboration system and information interaction system of reverse logistics in B2C e-commerce, builds the basic framework of reverse logistics system in B2C e-commerce, and discusses the possible system bugs. The reverse logistics system designed in this paper will be more suitable for the local government-led business cooperation platform organizations. It can create a regional B2C e-commerce reverse logistics Consortium for local governments, and even play a positive role in promoting the rapid development of the entire B2C e-commerce industry.
