Operational excellence in last-mile delivery is becoming increasingly challenging, highlighting the need for a strategic assessment framework to improve decision-making processes. This study aims to provide a strategic assessment tool for last-mile parcel delivery processes, which are critical in terms of service levels, cost management and sustainability. The study presents a comprehensive approach to identify and prioritise feasible strategies by combining qualitative data obtained from expert opinions with Strengths, Weaknesses, Opportunities, and Threats analysis (SWOT) and Multi-Criteria Decision-Making (MCDM) methods. As a result of semi-structured interviews conducted with nine experts, 27 strategic criteria were identified and classified under SWOT dimensions. The 10 strategies developed during the interviews were evaluated by using the Intuitionistic Fuzzy Set (IFS) approach, which considers expert reliability, the Full Consistency Method (FUCOM) for weighting, and the Complex Proportional Assessment (COPRAS) technique for final ranking. There is a clear gap in the literature regarding critical criteria and strategies for last-mile delivery in developing economies. Since it is not possible to implement all strategies simultaneously due to limited resources, the strategies proposed in this study have been prioritised according to their relative importance. While expert-based evaluations in the literature typically assume that experts have equal influence, this study differs from the literature by weighting experts based on their level of experience. This approach not only addresses the gap in strategy and criterion development in the literature but also offers a more realistic and feasible approach from an implementation perspective. The findings show that all strategies are meaningful in improving last-mile performance, but their impact levels vary. "Developing public and corporate strategies for environmental sustainability" stands out as the highest priority strategy with a performance index of 100 points, while "Incorporating parcel transportation-related topics into logistics management education" is considered as the lowest priority strategy with 91.94 points. Limitations of this study arise from the niche nature of the sector and the small sample size.

The main objective of this study is to investigate the effect of freight transportation on foreign trade in the Turkish maritime transportation sector. Data gathered from the Turkish Statistical Institute and the Ministry of Transport and Infrastructure's official websites, between the years 2013 and 2023, were utilized and time series analysis was conducted. The Industrial Production Index was used as a proxy for economic expansion. This research used five variables, all shown in logarithmic form (Export, Import, Volume, Handling, and Index). Unit root tests were done to examine the stationarity of the series. Regression analysis was conducted utilizing the Ordinary Least Squares (OLS) method to ascertain the short-term direction of the relationship between the variables. The findings from the Toda-Yamamoto causality test align with those derived from OLS and affirm that within the maritime sector, sea freight transportation exerts a positive impact on foreign trade, particularly in the short term.
