TAMİR SÜRECİNİ İÇEREN GERİ DÖNÜŞÜM SÜRECİ İÇİN YENİ BİR ENVANTER MODELİ GELİŞTİRİLMESİ

Öz

Bu çalışmada, geri dönüşüm süreci, kusursuz hale getirilmek için toplanan ürünlerin tamamının ya geri dönüşerek ya da kısmı geri dönüşerek işlendiği ve kalan kısmın ise tamir edildikten sonra geri dönüşüme verilmesi durumunu gösteren bir envanter modeli geliştirilmiştir. Önerilen model geri dönüşüm envanter modelinin tamir durumunu ele alan bir modelidir. Model örnek bir uygulama problemi ile desteklenerek çözümlenmiştir. Ayrıca talep, marjinal geri alım oranı ve kullanım oranı birim zamanda toplam maliyet gibi matematiksel maliyetleri ve çevrim sürelerinin değişim sonuçları için üç faktör üç seviye olacak şekilde bir tam faktöriyel L27 deney tasarımı uygulaması gerçekleştirilmiştir. Sonuçta geri dönüşüm ve tamir sürecinde marketlerden geri alınan ürünler hiç atık olmayacak şekilde ya geri dönüşüyor ya da tamir edildiği görünmektedir. Sonraki araştırma konusu olarak; geri dönüşüm envanter modelleri için araştırmacılar ve endüstri uygulamacıları için araştırma boşlukları ve fırsatları gösterilmiştir.

A NEW INVENTORY MODEL TO RECOVERY PROCESS WITH REWORK

Öz

A new inventory model has been developed for the reworked case that some of the products involved in the re-production process may be defective during the recovery process of the collected products on the recovery process in this paper. The proposed model has a reworked case of recycling inventory and it is supported by a numerical problem. In addition, a full factorial L27 test design was performed with three levels for three factors for a total cost per unit time, change in recycling and reproduction by batch size for marginal buyback rate, utilization rate and recycling good quality product ratio values with the different levels of demand. As a result, the effects of some defect of re-production processes in the recycling process have been shown with the proposed inventory model. In addition, research gaps and opportunities for researchers and industry practitioners for recycling inventory models are shown as further research of the model.
