Abstract

Nowadays, where the competitive business environment is getting deeper, improvements in Supply Chain Management (SCM) operations, which fundamentally affect the profitability, supply agility and process optimization of companies, are gaining importance. SCM is a process that aims to reduce costs and increase efficiency by managing the operations from the supply of raw materials to the delivery of final products to customers. SCM includes complex decision problems that require different decisions to be made under conflicting factors such as quality, cost and delivery time, and due to this structure, these problems are suitable to be addressed as Multi-Criteria Decision Making (MCDM) problems. In this study, the improvement of SCM processes of an international company was analyzed, and a solution approach based on mathematical methods was developed for the problem identified as a result of the root cause analysis carried out in the real-life application. In the study, first of all, the SCM process of Turkey-produced export products of a European-based automotive company was examined; root cause analysis was made for the problem with the fastest and least costly solution potential; the decision problem was addressed to eliminate the determined root cause was structured; and than, was solved with an approach based on the Best-Worst Method (BWM) - Combined Compromise Solution (CoCoSo). Multiple decision makers who manage the operations related to the strategic goals were employed in decision process in order to develop a solution that could simultaneously meet all three strategically determined managerial goals of the company. In this context; unlike the existing literature examples, the "K2: size and physical compatibility" criterion had the highest importance value, while, Supplier C was determined as the best alternative. The problem dimensions, factors and parameters considered in the decision problem were explained in depth to the readers, and, the results obtained were supported by detailed visual representations and presented to scientific researchers and field practitioners.

Özet

Rekabetçi iş ortamının gittikçe derinleştiği günümüzde şirketlerin karlılığını, arz çevikliğini ve süreç optimizasyonunu temelden etkileyen Tedarik Zinciri Yönetimi (TZY) operasyonlarındaki iyileştirmeler önem kazanmaktadır. TZY, hammaddelerin tedariğinden nihai ürünlerin müşterilere teslimine kadar olan süreçleri yöneterek maliyetleri düşürmeyi ve verimliliği artırmayı amaçlayan bir süreçtir. TZY içerisinde kalite, maliyet ve teslimat süresi gibi birbiriyle çelişen faktörler altında farklı kararlarının alınmasını gerektiren karmaşık karar problemleri barındırır, ve yapıları gereği bu problemler Çok Kriterli Karar Verme (ÇKKV) problemi olarak ele alınmaya uygundur. Bu çalışmada uluslararası bir firmanın TZY süreçlerinin iyileştirilmesi analiz edilmiş, ele alınan gerçek hayat uygulamasında yürütülen kök neden analizi sonucunda belirlenen problem için matematiksel yöntemleri taban alan bir çözüm yaklaşımı geliştirilmiştir. Çalışmada öncelikle Avrupa merkezli otomotiv firmasının Türkiye üretimli ihraç ürünlerinin TZY süreci incelenmiş, en hızlı ve en az maliyetli çözüm potansiyeline sahip problem için kök neden analizi yapılmış, belirlenen kök nedenin ortadan kaldırılması için ele alınan karar problemi yapılandırılmış ve En İyi-En Kötü Yöntemi (Best Worst Method – BWM) - Birleştirilmiş Uzlaşık Çözüm (Combined Compromise Solution - CoCoSo) temelli bir yaklaşım ile sonuca ulaşturulmıştır. Uygulama çalışmasında firmanın stratejik olarak belirlemiş olduğu üç yönetimsel amacı eşzamanlı sağlayabilecek çözümün geliştirilebilmesi adına bu stratejik hedeflere bağlı operasyonları yöneten birden çok karar verici yer almıştır. Bu bağlamda; mevcut literatür örneklerinden farklı olarak “K2:boyut ve fiziksel uyumluluk” kriteri en yüksek ağırlık değerine sahip olurken, Tedarikçi C en iyi alternatif olarak belirlenmiştir. Karar probleminde ele alınan problem boyutları, faktör ve parametreler okuyuculara derinlemesine açıklanmış ve elde edilen sonuçlar detaylı şekilsel gösterimlerle desteklenerek bilimsel araştırmacıların ve alan uygulayıcılarının kullanımına sunulmuştur.
