Maritime operations include potential human-made hazards. For this reason, evaluating human-made hazards for cost-effective ship management is of vital importance in the maritime industry. From past to present, researchers have attempted to offer preventive approaches to minimise human-made hazards. In this context, the present article proposes a hybrid approach through the integration of the Delphi, Analytic Hierarchy Process (AHP) and Human Error Assessment and Reduction Technique (HEART) methods. With this approach, human-made claims occurring during the handling and transport of steel cargo in bulk carriers were analysed. The outputs of the present article contribute to the improvement of overall safety levels of steel cargo and bulk carriers by considering the potential hazards in risk management.

Ships create a large amount of pollutions to marine and coastal environment where its pollutants have negative effects to human and maritime habitat. Depending on the nature of ship-generated waste, rules and regulations determine discharging procedures. This paper focuses on evaluating of potential hazards of ship-generated wastes on the environment whether it may be discharged into the sea or disposed of on port facilities. Thus, marine and costal environmental effects can be discussed analytically to improve human and ecological health. To achieve this purpose, analytic hierarchy process (AHP) extended with interval type-2 fuzzy sets (IT2FSs) is used. While AHP method is used for prioritizing the potential ship- generated waste, the IT2FSs deal with uncertainty and vagueness in the process of obtaining expert decision. Beside assessment of the environmental impacts, the paper contributes to enhance coastal and marine environmental awareness with respect to the ship-generated waste.

Морская отрасль является важнейшим звеном в международной торговле, так как морские суда представляют собой наиболее рентабельный способ доставки больших партий массовых грузов на значительные расстояния. Современная логистика перевозок массовых навалочных грузов идет по пути увеличения судовых партий и как следствие, за счет экономии издержек на эффекте масштаба последние годы произошел существенный рост размеров универсальных судов. На универсальных судах, за счет роста торговли продовольствием и сужения фрахтового рынка, в последние годы стали активно перевозиться зерновые навалочные грузы. Известно, что смещение навалочных грузов было связано с большими рисками опрокидывания от потери остойчивости для балкеров, где от потери остойчивости происходит более 46 процентов всех серьезных аварийных случаев. Проблема обеспечения остойчивости становится еще более актуальной при перевозке зерновых навалочных грузов, имеющих усадку примерно в два процента от своего объема, за счет чего во время рейса всегда образуются пустоты в трюмах между свободной поверхностью груза и палубой. Предполагается, что при максимально возможном смещении зерна его свободная поверхность образует с горизонталью углы в 15 и 25 градусов для заполненных и соответственно незаполненных отсеков. Для универсальных судов риски потери остойчивости от смещения груза при перевозках зерна, за счет масштабного эффекта большой удельной погрузочной кубатуры трюмов и высоты борта возрастают многократно.The Maritime industry is an important link in international trade because sea vessels are the most cost-effective way to deliver large quantities of bulk cargo over long distances. Modern transportation of cargo in bulk is on the path of increasing of shiploads and as a result, due to effective on scale effect, there has been a significant increase in the size of universal vessels in recent years. Grain bulk cargo has been actively transported on universal vessels in recent years due to the growth of food trade and the segmentation of the freight market. It is known fact that the displacement of bulk cargo in the vessel holds was associated with high risks of overturning from loss of stability for bulk carriers. More than 46 percent of all serious accidents occur from loss of stability. The problem of ensuring stability becomes even more urgent when transporting grain bulk cargo, which has a shrinkage of about two percent of its volume, which is a reason of free surface between the cargo and the deck inside of vessel holds. It is assumed that at the maximum possible displacement of the grain, its free surface forms angles of 15 and 25 degrees with the horizontal for filled and unfilled compartments, respectively. For multipurpose universal vessels, the risks of loss of stability during grain transportation due to cargo displacement and because of the large-scale effect of the large loading cubic capacity of the holds and the height of the side, increase many times.

This research studies heterarchical collaboration in logistical transport. Specifically, it utilizes a hybrid Delphi-Analytic Hierarchy Process (AHP) approach to explore the relevant criteria for the formation and maintenance of a strategic alignment for heterarchical transport collaboration. The importance of this work is that it applies a novel hybrid approach for identifying criteria for success to a little-studied form of supply chain collaboration: heterarchical collaborative transport. The criteria for this form of collaboration identified by the application of Delphi-AHP include ones from the technical, risk, financial, organizational, and operational categories. This novel application of the hybrid approach leveraged the expertise of transportation collaboration experts from the U.K., France, Canada, Sweden, the Netherlands, and Italy to identify key criteria for a strategic alignment between heterarchical collaboration partners. Such collaborative initiatives are important in industry as an environmentally conscious, yet efficient and effective strategy for the transport of raw materials and finished products in the supply chain.

This study proposes a novel evaluation model for lawyer selection incorporating the lawyer’s backbone leadership attitude employing the hybrid multi-criteria decision-making (MCDM) approach. In the proposed approach, the lawyer’s backbone leadership attitude is employed as an evaluation factor in the evaluation model for lawyer selection from law firms’ perspective. In this paper, a hybrid approach based on the Delphi technique and analytic hierarchy process (AHP) is proposed to manage qualitative and quantitative criteria for selecting the best alternative lawyer for law firms in China. Finally, a law firm in China is carried out to verify the feasibility of the proposed approach. Based on the result, the backbone leadership does provide valuable information in the evaluation model for lawyer selection. The results also revealed that the proposed approach would help law firms and human resource managers to understand and develop strategies to hire a lawyer.

Abstract Stringent regulations regarding environmental protection and energy efficiency (i.e., emission limits regarding NOx, SOx pollutants and the IMO greenhouse gases reduction target) will mark a significant shift to the maritime industry. In the first place, the shipping industry has strived to work towards feasible technologies for regulatory compliance. Nevertheless, life cycle cost appraisal attaches much consideration of decision-makers when it comes to investment decisions on new technologies. Therefore, the life cycle cost analysis (LCCA) is proposed in this study to evaluate the cash flow budgeting and cost performance of the proposed technologies over their life cycles. In the second place, environmental regulations may support innovation especially in the era of digitalization. The industrial digitalization is expected to revolutionize all of the aspects of shipping and enable the achievement of energy-efficient and environmental-friendly maritime operations. The so-called Internet of things (IoT) with the utilization of sensor technologies as well as data acquisition systems can facilitate the respective maritime operations by means of vessel operational performance monitoring. The big data sets obtained from IoT should be properly analyzed with the help of Artificial Intelligence (AI) and Machine Learning (ML) approaches. Our contribution in this paper is to propose a decision support framework, which comprises the LCCA analysis and advanced data analytics for ship performance monitoring, will play a pivotal role for decision-making processes towards cost-effective and energy-efficient shipping.
