Abstract

This study aims to provide an integrated decision-making approach in maritime transportation problems. The duty of hatch cover is to prevent the ingress of water into the cargo hold and protect the goods from being damped and damaged. Hence, it has the considerable role in productivity of maritime transportation systems. Since each hatch cover has distinguished properties with respect to criteria than the others, the hatch cover selection problem (HCSP) 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 criteria. In addition, an integrated group Shannon entropy- based weighted aggregated sum product assessment (WASPAS) approach is applied to solve the HCSP using the limit distance mean (LDM) in which the interval type-2 fuzzy 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 fulfilled in a real case study and the ranked results are compared with the others.
