A Mathematical Model Proposal for Sustainable Lean Reverse Logistics System

Öz

Dimensions of logistics can be handled in four different ways. These are inbound logistics, in-plant logistics, outbound logistics and reverse logistics. Reasons such as shortening product obsolescence, manufacturers' desire to reduce costs by using materials in returned products, and customers' purchasing tendencies shifting to electronic commerce have led to reverse logistics, one of the dimensions of logistics, being frequently discussed in academic and industry circles. In this study, a model proposal with sustainable and lean logistics perspective is presented. This model is a mathematical model that expresses the use of Cross-Dock and Milk-Run methodologies, which are lean transportation methods, in reverse logistics operation. This study aims to contribute to the gap in the literature regarding the number of studies with lean perspective among reverse logistics studies and is to reveal the operation structure model that will eliminate waste in reverse logistics operations, accelerate the flow, and provide efficiency with lean logistics techniques.

Sürdürülebilir Yalın Tersine Lojistik Sistem için Matematiksel Bir Model Önerisi

Öz

Lojistiğin boyutları dört farklı şekilde ele alınabilir. Bunlar inbound lojistik, in-plant lojistik, outbound lojistik ve tersine lojistiktir. Ürün eskime sürelerinin kısalması, üreticilerin iade ürünlerdeki malzemeleri kullanarak maliyetleri düşürme isteği, müşterilerin satın alma eğilimlerinin elektronik ticarete kayması gibi nedenler, lojistiğin boyutlarından biri olan tersine lojistiğin akademik ve endüstriyel çevrelerde sıkça tartışılmasına yol açmıştır. Bu çalışmada, sürdürülebilir ve yalın lojistik bakış açısıyla bir model önerisi sunulmuştur. Bu model, yalın taşımacılık yöntemlerinden olan Cross-Dock ve Milk-Run metodolojilerinin tersine lojistik operasyonunda kullanımını ifade eden matematiksel bir modeldir. Bu çalışma, tersine lojistik alanındaki çalışmalar arasında, yalın bakış açısıyla ele alınan çalışmaların sayısına ilişkin literatürdeki boşluğa katkıda bulunmayı ve tersine lojistik operasyonlarında israfı ortadan kaldıracak, akışı hızlandıracak ve yalın lojistik teknikleriyle verimliliği sağlayacak bir operasyon yapısı modelini ortaya koymayı amaçlamaktadır.
