Abstract

Just-in-Time (JIT) production system has first been used by Toyota Co. of Japan. Its sensitivity to waste and fighting with waste in order to reduce cost makes this production system very popular. In this study, supplier relations in JIT was studied. _The supplier relations of an electrical appliances production company, which has a JIT like production system, is examined. One of its products is chosen and the number of suppliers, which supply this product, are decreased from 83 to 19. Moreover, optimal batch size of the selected product is calculated and this batch size is used in calculating raw materials requirement. As a result of using this batch sizes, an important saving can be achieved in yearly inventory holding cost.

Özet

Tam Zamanında Üretim (TZÜ) sistemi ilk kez Japonya'da Toyota firmasında uygulanmıştır. Bu sisteminin imalat firmaları arasında gittikçe tercih edilmesi, israfa duyarlı olması ve maliyetleri azaltma çabası içinde olması dolayısıyladır. Bu çalışmada, TZÜ'de tedarikçi ilişkisi konusu ele alınmıştır. Elektrikli ev aletleri üreten ve TZÜ yapısına uygun üretim yapan bir firma tespit edilerek tedarikçi ilişkileri değerlendirilmiştir. Seçilen bir ürün için daha önce 83 olan tedarikçi firma sayısı 19'a indirgenebilmiştir. Ayrıca, bu ürün için en iyi üretim parti büyüklüğü hesaplanarak, ürünün bileşen-parça ihtiyaçları buna göre belirlenmiştir. Bunun sonucunda yıllık stok taşıma maliyetinde önemli bir düşüş sağlanabileceği tespit edilmiştir.
