Selecting carriers for overseas tank container transport with sustainability objectives

The logistics industry is increasingly prioritizing sustainability, requiring a comprehensive approach to carrier selection for transporting tank containers overseas. Current studies often focus only on economic factors, but social and environmental aspects are also crucial for sustainable logistics practices. This research introduces a Multi-Criteria Decision-Making (MCDM) framework combining the Best-Worst Method (BWM) and Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS). Through a literature review, expert interviews, and secondary data analysis, relevant criteria are identified. The framework is applied to a case study to evaluate carriers for overseas tank container transport on three major shipping lanes, incorporating sustainability objectives alongside traditional criteria. The results show a balanced and clear carrier selection process aligning with current sustainability goals. The findings highlight the possibility of including sustainability criteria without significant costs, providing practical recommendations for logistics companies to improve their carrier selection practices and support long-term environmental and social benefits.
