A Bayesian belief network model for integrated energy efficiency of shipping

Climate change is one of the major problems in today’s world and shipping has a direct influence ... more Climate change is one of the major problems in today’s world and shipping has a direct influence on climate change by the amount of energy consumed and volume of emission generated during shipping and port operations. Energy efficiency and port operation relationship have been widely mentioned in the existing literature under the term of energy efficiency management. However, there is still a need for detailed research on the ship-port interface development regarding holistic energy efficiency. The complex logistic processes should comprise with port performance to avoid the inevitable delays and to obtain a more energy efficient transport system. Therefore, ports and fleet can be managed together within a conceptual communication framework. The primary purpose of this research is to enhance the scientific understanding of port and ship operation inter-operability based on energy efficiency interactions. A theoretical framework is developed to investigate how ports and ships could w...

The complete-perfect information case of the players is taken into account and the Cournot-Nash equilibrium pure strategy solution concept is utilised. The approach developed in this study focuses on the current liner shipping alliance structure and assumes the long term stability of the current alliances. The research steps are mathematically integrated to different methodological outcomes and numerically tested in the given case study. The results suggested that, in a two year period, additional ship capacity deployment would reduce the competitiveness of the alliances. It is proposed that outcomes of this research will provide significant theoretical contribution to the existing literature and will generate a robust tactical decision support rationale regarding to the capacity depl...

Complex adaptive development analysis of marine container transport system

Marine transport is a waterway based, extremely competitive means of transport providing transfer... more Marine transport is a waterway based, extremely competitive means of transport providing transfer of high volume of cargo over long distances in the possible cheapest way. Marine transport system consists of ships, ports, waterways, intermodal connects, supportive systems (e.g. education, finance, customs, insurance etc.), and system users components. As nature of global trade developments, marine transport system components specialise on certain cargo types. Thus, it is possible to differentiate and to categorise marine transport systems for each major cargo types of seaborne trade. Evidently, containers are one of the main cargo types of shipping business at present and around 17% of total seaborne trade volume as weight is carried in container boxes. If we look at the value of cargo carried, we can notice that much higher proportion of seaborne trade as value is carried in container boxes. The marine transport system specialised on container cargo type can be called as “marine co...

Developing a policy management algorithm for ship provision: a Delphi Technique Integrated with Hesitant Fuzzy Set (DTIHFS) approach

Maritime Policy & Management

Specifically, ship provision decision-making consists of many uncertainties and a wide number of decision parameters due to the regional price and product quality differences. The primary objective of this study is to establish a decision support system for provision decision-making process. In order to achieve this, a policy management algorithm framework integrating the Delphi Technique (DT) and the Hesitant Fuzzy Set (HFS) approach was established. In the Delphi process, a survey was distributed to a group of experts from regional shipping companies. The overall consensus revealed that ship location, company policy, and inventory of products could be determined as the main decision-criteria consisting of various attributes which are expressed with linguistic terms. In order to transform linguistics terms to numerical values, the HFS was applied. This integrated methodological framework was also applied to selected case studies of two ships. It was found that it would be possible to reduce daily provision cost per crew from $10.36 to $8.24 and from $16.16 to $11.64, and to save, respectively, $19717.45 and $7404.45 within 453 and 470 days for given ships.

Developing multidisciplinary blended learning courses for maritime education with cross-European collaboration

Furthermore, the introduction of new technologies, the imposition of new regulations in the maritime industry and the growing challenges at port, shipping and logistics level increase the demand for new educational schemes. Concerning the market needs, TrainMoS II and On the MoSway Network (OTMW-N) European projects aimed for the development of student and professional's skills and laid the foundations for a cross-European maritime educational programme. TrainMoS II was the evolution of the TrainMoS project, improving the existing tools and covering a whole new range of technical and operational topics, including alternative fuels and technologies, logistics and safety issues such as damage control, evacuation and crisis management operations. TrainMoS II covered also the provision of blended vocational education to undergraduates and professionals who belong to different sectors in the multimodal transport chain. Both projects focused on the establishment of an educational framework facilitating the collaboration between industry and academia and used advanced ICT tools to match the maritime market needs with the training provision and to develop new and enriched content for the online platform with learning material and knowledge for both professionals and students. In the present study, the outcomes and experiences gathered from running the aforementioned projects are presented and discussed for their potential impact on the maritime industry.

Recent regulative approaches by the IMO are to enforce the shipping industry to become more energy efficient and sustainable. There is a growing amount of literature on the energy efficiency management of ships and ports. However, there is still inadequate research effort on the ship–port interface in order to obtain an Integrated Energy Efficiency framework for marine transport operations. In this research, a theoretical concept is generated to measure holistic energy efficiency in shipping operations. The main purpose of this paper is to identify nodes of the integrated ship-port energy efficiency framework and develop a probabilistic approach, which can help to increase energy efficiency and reduce CO2 emissions for shipping companies. This research generates an application of BBNs on ship–port interface regarding the integrated operational energy efficiency interactions by aiming to optimise holistic operational energy efficiency and CO2 emissions. The outcomes suggest that it would be possible to increase the probability of a more energy efficient and sustainable marine transport operation by integrating the influences of port and ship operation performances and their elements on the related route planning and slow steaming decision-making.

Triopoly Competition Analysis of New Generation Strategic Shipping Alliances in Marine Container Transport Systems

Competition conditions of shipping liners in marine container transport systems are gradually get... more Competition conditions of shipping liners in marine container transport systems are gradually getting tough due to excessive fleet capacity supplied to the container shipping market. As a result of environmental regulative enforcement of international regulatory bodies and economy of scale requirements of cost-reductive operational strategies, spreading of ship size enlargement trends in shipping industry became a known fact. Thus, matching supply and demand in acceptable ocean freights became even more challenging. In this respect, container shipping liners considered significant changes on their strategic shipping alliances. For this they investigated the increase of mutual benefits among cooperative competitors in order to adapt to the dynamically changing system environment. More robust and wider shipping alliances are planned to share and reduce risks of owning oversupply, and increase quality of shipping services by aiming to meet demand expectations optimally. As a response o...

In Izmir province of Turkey, three active container ports and two planned port investments are assumed to serve to shared hinterland in the near future. The methodological approach of this study aims to generate a Hybrid Port Competition Analysis Model (HPCAM) to apply on the port competition dynamics in Izmir with its different aspects. The study divides the HPCAM to two methodological stages. The first stage is application of the Multi Attribute Value Analysis (MAVA) of the decision science in order to determine competitiveness of the given port alternatives from hinterland and shipping liner perspectives. The second stage is the development of a non-cooperative zero-sum game concept to apply on the port competition regarding to inter-port competition strategy pay offs. Integration and comparison of the both methodological approaches by HPCAM present valuabl...
