Journal Article 2021 03 27 This study aims to provide an integrated decision-making approach in maritime transportation problems. The duty of the hatch cover is to barricade the entrance of water into the load container and insulate the material from being damaged. Hence, it has a considerable influence on the efficiency of maritime transportation systems. Since each hatch cover has distinguished properties with respect to criteria compared to the others, the Hatch Cover Evaluation Problem (HCEP) can be considered as a Multi-Criteria Decision-Making (MCDM) problem. In this paper, Interval Type-2 Fuzzy Sets (IT2FSs) are first used to weight criteria and evaluations of hatch covers with respect to the criteria. In addition, an integrated group Shannon entropy-based Weighted Aggregated Sum Product Assessment (WASPAS) approach is applied to solve the HCEP using the Limit Distance Mean (LDM), in which the Interval Type-2 Fuzzy (IT2F) Shannon entropy approach is used to determine the objective weights, and then they are integrated with the subjective weights. On the other hand, in order to demonstrate the effectiveness and practicability of the proposed method, it is illustrated in an example, and the ranked orders are analyzed with the others. https://scientiairanica.sharif.edu/article_24164_ba8f5d54f513cefec05e255b67cbfeee.pdf
