Fuzzy AHP and fuzzy TOPSIS integrated hybrid method for auxiliary systems of ship main engines

Although significant technical precautions have been taken in marine diesel engine and auxiliary systems, unexpected failures can be observed during operation. These failures can sometimes lead to irreversible losses. The purpose of the study is to present fuzzy Analytic Hierarchy Process (AHP) and TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) methods that can be applied for failure detection in auxiliary systems and marine diesel engine determined by group of experts. By evaluating the decision-making groups, the system most affected by failures was determined.
