Geri dönüşüm sürecinde kusurlu yeniden üretim durumu için yeni bir envanter modeli

Öz

Bu çalışmada, geri dönüşüm sürecinde toplanan ürünlerin yeniden üretim yoluyla geri kazanımı esnasında yeniden üretim sürecine dahil olan ürünlerin bir kısmının kusurlu olabileceği durum için yeni bir envanter modeli geliştirilmiştir. Önerilen model, bilimsel yazında yer alan Dobos ve Richter (2004) geri dönüşüm envanter modelinin kusurlu üretim durumunu ele alan özel bir halidir. Model örnek bir uygulama problemi ile desteklenerek çözümlenmiştir. Ayrıca, marjinal geri alım oranı, kullanım oranı ve geri dönüşüm iyi kalite ürün oranı değerleri için birim zamandaki toplam maliyet, geri dönüşüm ve yeniden üretim parti büyüklüğüne göre değişim sonuçları için üç faktör üç seviye olacak şekilde bir tam faktöriyel L27 deney tasarım uygulaması gerçekleştirilmiştir. Sonuçta, geri dönüşüm sürecinde yeniden üretim işlemlerinin de belirli bir oranda kusurlu olmasının etkileri gösterilmiştir. Bunun yanı sıra modelin gelecek araştırması olarak geri dönüşüm envanter modelleri için araştırmacılar ve endüstri uygulayıcıları için araştırma boşlukları ve fırsatları gösterilmiştir.

A new inventory model for re-production with imperfect items in recycling process

Öz

In this study, a new inventory model has been developed for the case that some of the products involved in the re-production process may be defective during the recovery process of the products collected via the recycling process. The proposed new model is a special case of Dobos and Richter (2004) recycling inventory model in the scientific literature dealing with the defective production situation. The model is solved by supporting wih a numerical instance. 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. 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.
