Yayın Selecting an alternative concrete batching plant location using IT2 fuzzy anp methodology(2022) Nalbant, Kemal Gökhan; Özdemir, Şahika; Özdemir, YavuzReady-Mixed Concrete started to be used after the 1970s, and its importance has gradually increased in recent years. The rapid development of the construction industry in our country in recent years has contributed to the rapid development of Ready-Mixed Concrete plants. Because of this reason, in this study, the concrete plant's location is determined using the Interval Type-2 Fuzzy Analytic Network (IT2 FANP) methodology. As a result of this methodology, the ranking of the alternative concrete plant's location is found as Basaksehir, Ikitelli, and Bagcilar, respectively. To the authors’ knowledge, this is the first study in the literature that searches for an alternative concrete batching plant location using Interval Type-2 (IT2) Fuzzy Multi-Criteria Decision Making (MCDM) techniques. The problem may be examined using various MCDM methodologies, and further solutions for selecting alternate concrete plant locations can be researched in the future. The value of this study is that it fills in a gap in the existing literature and serves as a foundation for future research in this sector.Yayın An interval type-2 fuzzy analytic network process for prioritizing of store plan alternatives produced with ruled based design(Pearl Publication, 2021) Özdemir, Şahika; Nalbant, Kemal Gökhan; Özdemir, YavuzThe widespread use of computer technologies in engineering and architecture provides essential contributions to engineers and architects in solving design problems. The computational design approach, which emerged depending on computer science and design theories and software and hardware technologies, is reflected in today's engineering and architectural works. In this study, store plan alternatives were prioritized by the Interval Type-2 Fuzzy Analytic Network (IT2 FANP) methodology, and the best alternative of store plans was selected. In addition, the results obtained for the four methods were compared. Type-2 Fuzzy Set can reduce the effects of vagueness and uncertainties. These sets make it probable to model uncertainties directly. There are very few studies on the IT2 FANP method for architectural design area in the literature. Our aim is to contribute to the literature by increasing the studies in this field.Yayın Fuzzy multi-objective evaluation of tourism investments in Turkey(Isparta Uygulamalı Bilimler Üniversitesi, 2021) Özdemir, YavuzSon yıllarda turizm, ülkeler için önemli iş alanlarından biri olmuştur. Özellikle 1980'lerden sonra turizmin bireysel kazançtan aldığı pay gün geçtikçe artmıştır. Bu nedenle bu sektöre yapılacak yatırımların yapılabilir ve mantıklı olması gerekmektedir. Ancak literatürde, hangi turizm türleri veya hangi yatırım sorularının sayısal olarak tartışılması ve hesaplanması gerektiği ile ilgili neredeyse hiç mühendislik çalışması yoktur. Bu çalışmada sayısal örnek için, ilk olarak mühendislik açısından bulanık ANP ile Türkiye'de yatırım yapmayı planladığımız turizm türüne karar verdik. Daha sonra bu turizm türü için Türkiye'den üç gerçek yatırım projesi bulunmuş ve bulanık ANP kullanılarak önceliklendirilmiştir. Bu projelere ait bu ağırlıkları ve finansal verileri kullanarak, bu üç yatırım arasında en uygun yatırımı görmek için bulanık çok amaçlı karar verme uygulanmıştır. Bu uygulama sadece Türkiye’ye değil, aynı karar verme teknikleri kullanılarak farklı ülkelere de uygulanabilmektedir. Bu makale, turizm literatürüne mühendislik bakış açısı getirmekte ve yatırımcılara yapılabilir yatırımlar konusunda yardımcı olmaktadır. Yazarların bilgisine göre bu çalışma, turizm yatırımlarını mühendislik bakış açısı ile sayısal olarak ele alan ilk çalışma olacaktır.Yayın Evaluating the campus climate factors using an interval type-2 fuzzy ANP(Yildiz Technical University, 2024) Nalbant, Kemal Gökhan; Özdemir, Şahika; Özdemir, YavuzUniversity campuses, characterized by their urban amenities, socio-cultural atmosphere, and diverse user population, play a significant role as public places in small cities. The physical layout of campus locations influences our views toward schooling. The concept of an inclusive campus climate refers to how people and groups perceive and interact with the environment within the campus community. The campus atmosphere encompasses the variety of people, their unique experiences, and the interpersonal contact among them. The membership functions of type-1 (T1) fuzzy sets (FSs) are represented in two dimensions, whereas the membership functions of type-2 (T2) FSs are represented in three dimensions. The introduction of this new third dimension allows for the direct modeling of uncertainties by pro viding more degrees of freedom. In addition, the membership value of T2 FSs is more adept at managing ambiguities. In this paper, an interval type-2 fuzzy analytic network process (IT2 FANP) is used to evaluate the weight of criteria decided by experts in the evaluation of campus climate factors with trapezoidal fuzzy numbers. The aim of this paper is to evaluate the campus climate factors using an IT2 FANP methodology. For this problem, the three main criteria and nine subcriteria were defined by experts. Therefore, the ranking of main criteria is “Physical Environment” > “Conceptual Environment” > “Administrative Environment”, and the ranking of subcriteria is found as “Social Environment” > “Exterior” > “Interior” > “Cultural Environment” > “Psychological Environment” > “Inclusive Goal and Perception” > “Economic Factors” > “Ac creditation” > “Legislation on Inclusive Design” by IT2 FANP methodology.
