Application of Fuzzy AHP for Assessment of Transitional Barriers to
Electronic Bill of Lading
- Authors: Bünyamin Kamal; Ozan Bayazit
  Abstract: Advances in technology have converted the traditional paper-based bill of lading into an electronic bill of lading (eBL) format in recent years. In this regard, different eBL systems have been introduced and are increasingly being employed in the maritime transportation industry. In line with this, some major container shipping lines have started to declare their eBL services to their customers recently. However, it has been observed that there have not been come across any Türkiye origin container shipping lines to utilize eBL systems. Therefore, considering container shipping lines of Türkiye, this paper sought to disclose the barriers to the transition of eBL systems in Türkiye. The barriers have been revealed through literature review and confirmed by industrial experts. Following that Fuzzy-AHP method was performed to prioritize their importance quantitatively. It was revealed that the legal barrier among the main barriers appeared as the most important barrier.

Evaluation of Historical Changes Landing Data of Three Important Demersal
Fish Species of Black Sea
- Authors: Serap Samsun
  Abstract: In this study, the spatial and temporal changes in the landings of whiting (Merlangius merlangus), red mullet (Mullus barbatus) and turbot (Scophthalmus maximus) caught in the Black Sea were discussed using the open access data set of officially recorded landing statistics published by Turkish Statistical Institute (TUIK). The landings of whiting in Turkish seas increased steadily from 1981 to 1988, reaching the highest amount in the 56-year period in 1988. In order years, fluctuation was observed in the production. The catch quantity of red mullet, which continued to increase until 1989, has been decreasing since then and reached its lowest catch amount since 1971 in the year 2022. Turbot, which had the highest catch in 1983, has a catch amount of less than 1000 tons since the early 2000s. In the period between 1967 and 2022, when comparing the production amounts of the Eastern and Western Black Sea, it was found that the majority of the red mullet and turbot catch was obtained from the Eastern Black Sea. Although the catch amount of whiting was high in the Eastern Black Sea until 2017, it has been determined that the Western Black Sea has had more catch since 2017.

The Factors of Port Congestion and the Analysis of Strategies Towards
Solution
- Authors: İlke Sezin Ayaz; Umur Bucak
  Abstract: As a result of the rapidly increasing competitive conditions in the port industry, the concept of port performance has gained great importance. The concept of port congestion, which has been experienced frequently in recent years and deeply affects port performance, also comes to the fore as a problem that needs to be addressed in terms of port competition. Starting from this point in the study, firstly, semi-structured interviews were conducted with the managers of the ports operating in various regions of Türkiye, and the reasons for port congestion and the most frequent periods, the measures that can be taken against port congestion, and the strategies that can be developed were investigated. Then, port congestion factors and preventive strategies were prioritized using Fuzzy AHP-TOPSIS hybrid method. When the results of the semi-structured interviews were analyzed, it was determined that there was a lack of capacity; when the fuzzy AHP-TOPSIS results were examined, it was concluded that unexpected trade density was the most important underlying reason for port congestion. Moreover, according to both the semi-structured interview and Fuzzy AHP-TOPSIS results, it was concluded that cooperation with stakeholders and investment in qualified human resources would be the most effective measures to prevent port congestion. It is thought that the determined and prioritized measures and strategies against port congestion as a result of this exploratory study will benefit the port industry.

Forecasting Ro-Ro Freight Transportation Demand at Samsun Port: A Hybrid
Method Approach
- Authors: Tayfun Şimşek; Fırat Sivri, Özkan Uğurlu, Mehmet Aydın
  Abstract: Türkiye's extensive coastline and geopolitics position necessitates the importance of Ro-Ro transportation with neighbouring countries. Türkiye's rapidly growing Ro-Ro transportation significantly contributes to imports and exports, which is of great importance to the national economy. Samsun Port is one of the most active ports in Türkiye's Ro-Ro transportation sector, operating in the Black Sea region. This study examined Ro-Ro transportation at Samsun Port, and future cargo forecasting was conducted. For this purpose, artificial neural networks and time series analysis methods were combined. Input variables used in the study included the number of Ro-Ro ships arriving at the port between 2009 and 2021, population figures, a specialized CPI indicator (fresh fruits and vegetables), and export values. The output variable was the amount of cargo carried by Ro-Ro ships. According to the results obtained, it was observed that Samsun Port would have sufficient capacity for Ro-Ro transportation in the next 27 months in terms of wharf, port area, and operational space.

Analysis of Internal and External Factors Affecting Liquid Chemical Cargo
Port Efficiency
- Authors: Ercan Yüksekyıldız
  Abstract: The measurement of port efficiency is a crucial requirement in the maritime sector and has been the subject of numerous studies due to its direct impact on international trade. The methods used to determine port efficiency vary depending on the characteristics of the operations under investigation. Depending on which port operations are assessed, port adequacy can be measured in various ways. In the literature, it is evident that port efficiencies are mostly determined using numerical methods. However, when analyzing port efficiency, measuring it solely through numerical processes can lead to misleading results in some cases. To avoid this, it is necessary to analyze non-numerical internal and external factors that affect port efficiency. In this study, non-numerical internal and external factors influencing port efficiency in liquid chemical cargo ports were identified through a literature review and by experts. The identified factors were evaluated through surveys conducted with experts specializing in liquid chemical cargo ports. The survey results were analyzed using SPSS 21.0 statistical software. According to the results obtained from the surveys, factors such as the location and dimensions of the port area, the adequacy of hinterland connections and logistic facilities, well-organized physical surroundings of the port, the use of technological innovations, and the proper functioning of the quality control system were identified as significant factors affecting port efficiency. In addition to these factors, accurate job analysis in the port, satisfactory wages, sufficient education levels, and morale of port personnel were also found to be crucial factors influencing port efficiency.
