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.

Gemi Ana Makine Seçiminde Temel Faktörlerin Bulanık AHP Yöntemi ile Değerlendirilmesi

Öz

Gemi ana makine seçimi, geminin genel performansını, verimini ve işletme maliyetlerini etkilediği için gemi inşa sürecinde kritik bir karardır. Bu çalışmada Bulanık Analitik Hiyerarşi Sürecini (AHP) kullanarak gemi ana makine seçim kriterlerinin kapsamlı bir değerlendirmesi yapılmıştır. Bu yaklaşım, nitel ve nicel verileri içeren kriterleri göreceli önemlerine dayalı olarak değerlendirmek için sistemli bir çerçeve sunmaktadır. Ana makine seçiminde, ekonomik, teknik ve şirketle ilgili kriterler olmak üzere üç ana kriter belirlenmiş ve her bir ana kriter dört alt kriter ile detaylandırılmıştır. Sonuçlar, her bir alt kriterin göreceli önemini birlikte değerlendirildiğinde, yakıt tüketiminin genel önemin %17.01'ini oluşturan en yüksek öncelik olarak ortaya çıktığını göstermiştir. Bunu yakından takip eden makinenin kolay kullanımı ise %16,11'lik oranla ikinci sırayı alarak büyük önem arz etmiştir.
