Assessing Key Factors in Marine Main Engine Selection using Fuzzy AHP Method

Abstract

The main engine selection is a critical decision in the shipbuilding process, as it impacts the vessel's overall performance, efficiency, and operational costs. In this article, we present a comprehensive evaluation of marine engine selection criteria using Fuzzy Analytical Hierarchy Process (AHP). This approach provides a systematic framework for evaluating the criteria based on their relative importance, incorporating both qualitative and quantitative data. In the selection of the main engine, three main criteria were determined as economic criteria, technical criteria, and company-related criteria, and each main criterion was detailed with four sub-criteria. The results indicated that after considering the relative significance of each sub-criterion, fuel oil consumption emerged as the top priority, accounting for 17.01% of the overall importance. Following closely behind, easy operation held the second position with a rating of 16.11%, signifying its considerable importance.
