Abstract (2. Language): 
The Theory of Constraints (TOC) is a problem solvingapproach implemented in manufacturing and service processes to determine bottlenecks and improve productivity. In this study, TOC is utilized to improve the delivery process in petroleum and petroleum products transportation. The delivery process of petroleum and petroleum products is analyzed and improvements are suggested to shorten the period of importation procedure. The process of proving the fitness of imported petroleum products to the national specifications is called as the “Nationalization Process.” The Company cannot introduce the products to the market before all these analyses are completed. This delay incurs notonly opportunity costs but also waiting costs suchas rent, insurance, and risk. This study is focused onthe “nationalization process” and suggestions are presented to shorten the period. Finally, it is found that if the suggestions are realized, the nationalization process can be shortened
Abstract (Original Language): 
Kısıtlar Kuramı üretim ve hizmet sistemlerine dar boğazları tespit etmek ve verimliliği arttırmak amacıyla uygulanan bir problem çözme yaklaşımıdır. Bu çalışmada petrol ve petrol ürünlerinin dağıtım sürecini geliştirmek amacıyla Kısıtlar Kuramı’ndan yararlanılmıştır. Petrol ve petrol ürünleri dağıtım süreci incelenmişve ithalat sürecini de kapsayan bu süreci kısaltmaya yönelik öneriler mantık ağaçları kullanılarak geliştirilmiştir. Firmanın ithal ettiği petrolün ulusal standartlara uygunluğunu ispat etmek için izlediği sürece “ulusallaştırma” süreci adı verilmektedir. İthal petrol; analiz ve testlerin tamamlanmasından önce pazara sürülememekte ve işlenememektedir. Bu beklemeden kaynaklanan gecikme hem fırsat maliyetine hem de kira, sigorta ve risk gibi kalemlerde maliyetlere neden olmaktadır. Bu çalışma söz konusu ulusallaştırma sürecini incelemekte ve bu periyodu kısaltmayayönelik öneriler sunmaktadır. Bu iyileştirmeler sonucunda süreçte çok önemli bir kısalmanınolabileceği görülmüştür
