Karar verme ve performans değerlendirme süreçlerinde kriter ağırlıklarının belirlenmesi için kullanılan SWARA yöntemi ile, literatürde 3 ana başlık ve 14 temel parametre altında ele alınan biyofilik tasarım parametrelerinin ağırlıklarının hesaplanması amaçlanmıştır. Bu maksatla, 40 kişilik ulusal ve uluslarası düzeyde akademik ve uygulama yapan mimara bir anket çalışması yapılmıştır. Elde edilen anket sonuçları SWARA yönteminde kullanılmış ve biyofilik tasarım parametrelerinin ağırlıkları belirlenmiştir. Elde edilen sonuçlara göre literatürde yer alan parametrelerden manzara (geniş görüş alanı), doğa ile görsel bağlantı ve doğal sistem ve süreçlerle bağlantı parametreleri en önemli tasarım parametreleri olarak belirlenmiştir. Ayrıca elde edilen bu sonuçların ilerleyen çalışmalarda kullanılması ve “Biyofilik Ayaz İzi” veya “Biyofilik Yeterlilik Katsayısı” gibi kavramların literatüre kazandırılması amaçlanmaktadır.Book Part State of the Art of Apple Waste in the Circular Economy(IGI Global, 2023) Büyükselçuk, E.Ç.; Endüstri Mühendisliği BölümüWith the increasing world population, the use of resources has accelerated, environmental problems have increased, and the climate crisis has been faced. As in many sectors, investments are made for the changing process in industry, food, agriculture, livestock, and similar fields. Studies are carried out to evaluate various fruit and vegetable wastes obtained as a result of agricultural activities all over the world. One of these products is apple. In the literature, there are studies on waste generated after processing apple fruit as fruit juice or other apple products. It would not be correct to qualify these residues as waste. Revaluation of these wastes as a result of certain processes is one of the activities of the circular economy. In this chapter, different evaluation methods such as composting, bioenergy production, biochemical production, landfilling, animal feed production, or vegan leather productions that can be applied to apple waste are introduced. The application of different evaluation methods, their advantages and disadvantages are examined. © 2023, IGI Global.Article Elektrikli Araçların Performanslarının Crıtıc-eatwıos ile Değerlendirilmesi(2022) Büyükselçuk, Elif Çaloğlu; Tozan, Hakan; Endüstri Mühendisliği BölümüKüresel ısınma neticesinde tüm uluslar birtakım önlemler almak üzere harekete geçmişlerdir. Bu önlemler çerçevesinde ülkeler elektrikli araçların üretimi ve satışı üzerine yoğunlaşmışlardır. Ülkemizde de son yıllarda bu araçların kullanımı giderek yaygın hale gelmektedir. Bu çalışma, piyasada mevcut araçların performanslarını değerlendirerek alıcılara karar verme süreçlerinde destek olmayı amaçlamaktadır. Literatürde elektrikli sportif çok amaçlı araçların (Electric Sports Utility Vehicles, e-SUV) verimliliğini bütünleşik Kriterler Arası Korelasyon Yoluyla Kriterlerin Önemi (CRiteria Importance Through Intercriteria Correlation-CRITIC) ve Girdi-Çıktıların Tatminine Dayalı Etkinlik Analizi Tekniği (Efficiency Analysis Technique with Input Output Satisficing-EATWIOS) yöntemlerini kullanarak değerlendiren bir araştırmaya rastlanmamıştır. Bu çalışma bu boşluğu doldurarak, e-SUV’ların verimliliklerini değerlendirmektedir. CRITIC yönteminden elde edilen ağırlıklar EATWIOS yönteminde kullanılarak e-SUV’ların verimlilikleri değerlendirilmiştir. Belirlenen yedi tane girdi ve dört tane çıktı faktörüne göre Türkiye’de satılan beş farklı markaya ait e-SUV’lar performans açısından değerlendirilmiştir. e-SUV satın alma sürecinde enerji tüketiminin, fiyatın ve araç ağırlığının önemli faktörler olduğu sonucuna varılmıştır. Sonuç olarak İngilizler tarafından üretilen e-SUV’un en iyisi olduğu sonucuna ulaşılmış ancak verimliliğin çok yüksek olmadığı, verimliliğin arttırılması için çalışmalar yapılması gerektiği vurgulanmıştır.Article Evaluation of the Barriers to Maintenance 4.0 for the Textile Industry via Pythagorean Fuzzy SWARA(MDPI, 2025) Turan, Hakan; Buyukselcuk, Elif Caloglu; Endüstri Mühendisliği BölümüMaintenance 4.0 studies have become a focus for managers and employees when developing effective and efficient maintenance policies. In this study, the barriers to Maintenance 4.0 applications in the textile industry are investigated, and these barriers are weighted using the Stepwise Weight Assessment Ratio Analysis (SWARA) method based on Pythagorean fuzzy numbers. Solutions to address these barriers are presented. As a result of this study, Organizational and Managerial emerged as the most important main criterion. Operational was identified as the second most significant main criterion, followed by Technical Competence. Data-Related and Cybersecurity ranked fourth in terms of importance. On the other hand, Human Resources and Training and Financial were found to be the least important main criteria. These two criteria received lower importance scores compared to the others, with Financial being the criterion with the lowest overall significance. Sensitivity analyses were performed for six different scenarios by changing the importance weights of the decision-makers. The ranking of the criteria only slightly changed with the weights; this means that the results obtained in Case 1 are robust and reliable. Even in Case 6, where the expert weight ratios were completely reversed, the results did not change significantly. This highlights an important point regarding the reliability of the assessment.Article Citation - WoS: 13Citation - Scopus: 13The Best Whey Protein Powder Selection Via Vikor Based on Circular Intuitionistic Fuzzy Sets(Mdpi, 2023) Buyukselcuk, Elif Caloglu; Sari, Yigit Can; Endüstri Mühendisliği BölümüPeople try very hard to have a symmetrical, strong, and beautiful body. The human body needs high amino acids for muscle protein synthesis. Whey protein is a good choice that contains all amino acids, which increases muscle protein synthesis and improves body shape with resistance exercise. For this reason, those who do sports, especially professionals, prefer to use these products frequently. A large number of commercial whey protein powders are sold on the market, and to achieve maximum purpose, individuals want to use the best one. Intuitionistic fuzzy sets are used in order to minimize the negative effects of the uncertainty environment and ambiguous information encountered in the decision-making process on the solution. In this study, VIKOR, based on the circular intuitionistic fuzzy set, has been used to determine the best whey protein supplement. In line with the comprehensive literature review and expert opinions, the evaluation criteria affecting the selection process have been determined, and the solution of the problem has been focused.Article Integrated Entropy-Edas Methods for the Electrified Car Selection Problem(2022) Tozan, Hakan; Büyükselçuk, Elif Çaloğlu; Endüstri Mühendisliği BölümüIncreasing air pollution affects the environment and life negatively. For a sustainable environment and life, people, voluntary organizations, and governments need to work on the solution of this problem. The biggest sources of air pollution are transportation vehicles. For this reason, many countries in Europe have stated that they will use solely electrified cars to reduce air pollution in the future. Therefore, in this study, it is aimed to determine the best electrified car. The result obtained can support consumers that to intend to buy an electrified vehicle in the decision-making process. This problem is a typical multi-criteria decision making (MCDM) problem and some MCDM techniques are used to solve these problems. Here, the Entropy method was used to determine the weights of the selection criteria. Selection criteria was determined according to comprehensive literature survey and interviews with sales representatives. The EDAS (Evaluation based on Distance from Average Solution) method was used to rank the electrified car alternatives that sold in Turkey. As a result of the evaluation, the most important criteria was determined by the price of the vehicle, the net battery capacity, and the electric motor power. According to these criteria, the electrified car manufactured in China was chosen as the best.Book Part Citation - Scopus: 1Where Are We and What Should We Do in Cleaner Production Transformation(IGI Global, 2023) Büyükselçuk, E.Ç.; Endüstri Mühendisliği BölümüUntil recently, production models developed according to market conditions focused on reducing costs and increasing profitability at the expense of the destruction of natural resources and the deterioration of ecological balance and human health. However, today, with the effects of the deterioration in the ecosystem reaching sensible dimensions and being accepted as a global threat, a new production approach is needed. Due to environmental pressures, new markets and scarce resources, development, and economic growth are being tried to be redefined. Traditional production methods and environmental technologies are no longer sufficient to provide resource efficiency and increase environmental performance. Therefore, the need for new systems, processes and technologies has arisen for the restructuring of the industry and the creation of green business models. In this chapter, it is discussed how the cleaner production approach will contribute to this transformation, considering the green transformation efforts in question and considering the current situation of the Turkish industry. © 2023, IGI Global.Article Citation - WoS: 1Citation - Scopus: 1Analyzing Critical Success Factors of Sustainable Knowledge Management: an Interval-Valued Neutrosophic Approach(Mdpi, 2024) Turan, Hakan; Bulak, Muhammet Enis; Buyukselcuk, Elif Caloglu; Endüstri Mühendisliği BölümüKnowledge management (KM) is a structured approach that includes the organized procedures of generating, capturing, arranging, storing, retrieving, distributing, and harnessing an organization's knowledge resources to attain its goals and improve its effectiveness. Encountering uncertainty and managing imprecise information are fundamental aspects of KM that cannot be avoided. In this context, sustainable KM aims to solve these issues and address prioritizing the long-term sustainability and efficiency of knowledge-related processes within an organization. The aim of this study is to structure a sustainable KM concept for organizations and identify the most common critical success factors (CSFs) with a novel analytical approach. In this context, the Interval-Valued Neutrosophic methodology, which is one of the multi-criteria decision methods (MCDMs), was adopted to evaluate and weight the determined CSFs. Four main headings-KM, environmental, economical, and social criteria-are evaluated along with their subfactors. Our findings show that KM is found to be the most important, and environmental factors followed KM. When the results are examined in terms of subfactors, cleaner production is found to be the most significant, with a global weight value of 11.13.Article Citation - WoS: 2Citation - Scopus: 3Player Selection in Football by Integrated Swara-Vikor Methods Under Fuzzy Environment(Cell Press, 2024) Buyukselcuk, Elif Caloglu; Badem, Eray; Endüstri Mühendisliği BölümüThis study aims to provide an objective evaluation and selection of the most suitable players for the Turkish National Football Team by using multi-criteria decision-making methods, specifically Stepwise Weight Assessment Ratio Analysis (SWARA) and VIsekriterijumsko KOmpromisno Rangiranje (VIKOR) based on neutrosophic numbers. In the initial step of the study, the important criteria for player selection were determined, and a total of 21 and 26 criteria were identified for goalkeeper and players, respectively. Agility, reflexes and jumping ability are very important for goalkeeper whereas marking, passing ability, agility, dribbling, and footwork are the most important criteria for players. The performances of the players were evaluated due to these criteria and finally the Turkish National Football Team was established scientifically because of the best player selection. This decision-making process will be more beneficial in making more informed and effective decisions in the national team's player selection process. The success of the team can be improved by providing an objective and systematic player selection approach.
