Selection of the Best LNG Natural Gas Supplier with Multi-Criteria Decision-Making Techniques: Turkey Example in Current Conditions

Öz:
Decision of supplier selection has a crucial importance for a firm to succeed. Liquefied Natural Gas (LNG)is a crucial alternative to ensure the safety of natural gas supply in today's conditions, especially for the stateof natural gas supply security. LNG supplier selection constitutes the most important key point of thisprocess. This study aims to make the selection of the best LNG natural gas supplier for Turkey using theAnalytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution(TOPSIS) methods according to the current conditions. For this purpose, expert opinions, activity reportsand literature reviews were made to determine main and sub criteria. AHP method is applied by using ExpertChoice Software and TOPSIS was analyzed with Microsoft Excel for the best supplier choice. In addition,it has been shown that which criteria brings which alternatives forward, which criteria are decisive in theresult and which are not decisive.

Çok Kriterli Karar Verme Teknikleri ile En İyi LNG Doğal Gaz Tedarikçisinin Seçimi: Mevcut Koşullarda Türkiye Örneği

Öz:
Tedarikçi seçimindeki karar, bir firmanın başarılı olması için çok büyük bir öneme sahiptir. Sıvılaştırılmış Doğal Gaz (LNG), günümüz şartlarında, özellikle doğal gaz arz güvenliği durumunda, doğal gaz arz güvenliğini sağlamak için çok önemli bir alternatiftir. LNG tedarikçi seçimi bu sürecin en önemli anahtar noktasını oluşturmaktadır. Bu çalışma, mevcut koşullara göre İdeal Çözüm (TOPSIS) Yöntemlerine Benzerlikle Analitik Hiyerarşi Süreci (AHP) ve Sipariş Tercihi Tekniği kullanılarak Türkiye için en iyi LNG doğal gaz tedarikçisinin seçimini yapmayı amaçlamaktadır. Bu amaçla ana ve alt kriterleri belirlemek üzere uzman görüşleri, faaliyet raporları ve literatür taraması yapılmıştır. Uzman Seçim Yazılımı kullanılarak AHP yöntemi uygulanır ve en iyi tedarikçi seçimi için TOPSIS Microsoft Excel ile analiz edilmiştir. Ayrıca, hangi kriterlerin hangi alternatifleri öne çıkardığı, sonuçta hangi kriterlerin belirleyici, hangilerinin belirleyici olmadığı gösterilmiştir.
