An Application with Ahp – Topsis and Fuzzy AHP – Topsis Integrated Approach in Smartphone Selection
Özet
This study by Hakan Aydoğan evaluates smartphone selection by comparing traditional and fuzzy integrated multi-criteria decision-making approaches, specifically combining the Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Eight informatics experts assessed eight flagship smartphone models—Xiaomi Redmi Note 11 Pro, Oppo Reno 6, Reeder P13 Blue Max Pro, Apple iPhone 13, Casper Via X20, Samsung Galaxy S22 Ultra, General Mobile GM22 Pro, and Huawei P40 Pro—across eight evaluation criteria: Price, Prestige, Camera Resolution, Battery Capacity, RAM Capacity, Internal Storage, Screen Size, and Weight. Both traditional AHP and Fuzzy AHP revealed that Price was the most vital criterion, followed closely by Battery Capacity and Prestige. Nevertheless, the ranking of alternatives differed between the two methodologies: traditional TOPSIS ranked Xiaomi Redmi Note 11 Pro first, followed by Samsung Galaxy S22 Ultra and Apple iPhone 13, whereas Fuzzy TOPSIS positioned Apple iPhone 13 at the top, followed by Xiaomi Redmi Note 11 Pro and Samsung Galaxy S22 Ultra. Ultimately, the research demonstrates that applying fuzzy logic accounts for inherent ambiguity and qualitative uncertainty in expert evaluations, leading to critical rank alterations among alternatives with close numerical scores on a price-to-performance basis.
