    Türk İnşaat Sektöründe 3B Baski Teknolojisinin Benimsenmesini Etkileyen Ana Etkenler ve Engeller
    (2025) Latifiilkhechi, Leva; Aminbakhsh, Saman; Akçay, Emre Caner
    Bu çalışmada, Türk inşaat sektöründe 3B baskı teknolojisinin benimsenmesini etkileyen temel faktörler incelenmiştir. Bu doğrultuda, kapsamlı bir literatür taraması sonucunda 27 teşvik edici ve 19 engelleyici faktör belirlenmiş olup, bu faktörlerin değerlendirmesi 106 uzmandan oluşan bir anket çalışması ile yapılmıştır. Bu faktörlerin önemi, Göreceli Önem İndeksi (GÖİ) kullanılarak değerlendirilmiş ve ardından Analitik Hiyerarşi Prosesi (AHP) ile faktörlerin önem düzeyleri belirlenmiştir. 3B baskı teknolojisinin daha hızlı inşaat, iş kazalarının azalması, enerji verimliliğinin artması ve karmaşık tasarımların daha kolay uygulanması gibi avantajlar sunduğu görülse de, bu teknolojinin benimsenmesini engelleyen başlıca zorluklar arasında 3B Beton Baskı için yeterli düzenlemelerin ve yapı kodlarının eksikliği, büyük ölçekli uygulamalar konusunda sınırlı bilgi ve yalıtım malzemelerinin yetersizliği yer almaktadır. Araştırma sonuçları, malzeme israfını azaltma ve daha fazla özelleştirme imkânı sağlama gibi faktörlerin 3B baskının inşaat sektöründe benimsenmesinde en önemli etmen olduğunu, gözetim maliyetlerinin azaltılmasının ise en az önemli teşvik edici faktör olduğunu ortaya koymuştur. Diğer yandan, siber güvenlik riskleri, potansiyel iş kayıpları ve basılı yapıların katmanlı ve pürüzlü yüzeyleri, en kritik engeller olarak belirlenmiştir. Bu araştırma, 3B baskı teknolojisinin inşaat sektörüne entegrasyonunun artırılması için bu etmenlerin ve engellerin hedefe yönelik stratejilerle ele alınması gerektiğini vurgulamaktadır.

    Determination of Key Performance Indicators for Measuring Airport Success: a Case Study in Libya
    (Elsevier Ltd, 2018) Eshtaiwi,M.; Badi,I.; Abdulshahed,A.; Erkan,T.E.
    Airports need to evaluate their performance and effectiveness periodically to determine whether objectives are being achieved and how their performance compares to similar best practices. The goals of this paper are twofold: First, to offer a list of essential airport key performance indicators (KPIs) that can provide decision makers in the Libyan airport industry a practical framework to measure and monitor performance over time. The second goal is to use the AHP technique to derive the weights of the KPIs and to select the best international airport in Libya based on the values of the KPIs at each airport according to the judgments of experts. However, the implementation steps of the AHP method will be simplified by using the Expert Choice software. The paper presents the importance weights of seventeen KPIs across five aspects of airport performance. As a result of this study, Libyan airports can benchmark their performance against others or through internal benchmarking. © 2017 Elsevier Ltd

    Combining AHP and ROC with GIS for Airport Site Selection: A Case Study in Libya
    (Mdpi, 2020) Erkan, Turan Erman; Elsharida, Wael Mohamed
    Choosing airport locations requires thorough and comprehensive decisions to be made. To do so in a professional and logical manner is crucial for the social, economic, and logistic settings intended for any region. The present research takes place in Libya, where airports are just as vital for the economy in terms of tourism and investment by allowing for improved transportation throughout the developing market and supplier locations as well as trading between the industrial and financial sectors. For this reason, using the geographic information system (GIS) to determine the appropriate airport site, twenty-three criteria were considered. In addition, two different methods-analytic hierarchy process (AHP) and rank order centroid (ROC)-were utilized to derive the related weights. The comparison of the output maps from these two distinctive approaches shows that both approaches provide identical results. Finally, a sensitivity analysis was carried out to evaluate the reliability of the method used and select the best site among the proposed ones based on the result of the highest suitability index for each candidate site. This research provides a siting approach and substantial support for decision-makers in the issue of airport locations selection in Libya and other developing countries.

    Selecting the Best Warehouse Data Collecting System by Using Ahp and Fahp Methods
    (Univ Osijek, Tech Fac, 2014) Erkan, Turan Erman; Can, Gulin Feryal; Industrial Engineering
    Recently companies have begun to use their storage effectively to attain leadership in the market environment, utilizing Barcode and RFID (Radio Frequency Identification) systems for warehouse management. In this study AHP (Analytic Hierarchy Process) and FAHP (Fuzzy Analytic Hierarchy Process) are used to choose between Barcode and RFID systems for the company warehouse data collection system. This decision is affected by four criteria which are: cost, functionality, sustainability and performance. The barcode system was preferred by 68 % and RFID was preferred by 32 % according to AHP. For FAHP, barcode system was preferred by 72 % and RFID was preferred by 28 %. Consequently AHP values are consistent with FAHP values. Finally barcode system is selected for the company's warehouse data collection system and FAHP is found to be relatively more sufficient in terms of description of this decision-making process because of its fuzziness and vagueness compared to AHP method.
