We use optimal control theory to determine the manufacturing, remanufacturing, and disposal rates in a closed-loop supply chain. The returned items are of different quality levels. firm grades according their quality. Each class is remanufactured stocked separately. Also, all subject deterioration rate depends on class. Finally, each sold segment customers. An illustrative example presented alo...

Due to increasing environmental awareness, companies have started embracing the green supply chain concept reduce waste of resources. Based on this increased an integrated closed-loop has been developed, which integrates forward and reverse chain. The follows same path as in direction recycle used products. uncertain quality products, not all products can be selected for recycling reproduction,...

Nowadays, enterprises have to be good for society, take care of the environment, and achieve profit at same time. And closed-loop supply chain helps them being so. However, there is a lack bibliometric visualization research in area “Closed-Loop Supply Chain”. Thus, this aims present overview define current state scientific production regarding The review 807 publications from Scopus database (...

This research work develops a decision support model for a network design problem concerning a spare parts closed loop supply chain. It involves the formulation of an optimization model that takes on a mid to long-term planning perspective and covers decisions that have lasting and binding impact on organizational performance. These decisions include investment, location assignment, and invento...

Supply chain management, Network design, Closed-loop supply chain, disruption. This paper presents an optimization model for the design of a closed-loop supply chain network consisting of suppliers, production facilities, recovery centers, disposal centers, and markets. The proposed model is capable of accounting for risks of disruption and investigating the lateral transshipment strategy to re...

With progressing technologies and new features of production, new products compete with older ones in markets. Indeed, new products initiate contest with olden ones and this process repeats in different productions lifetime several times. In this situation recycling the olden products seems to be significant for supply chains. Governments often levy special tariffs for these products as a contr...

In this paper, a novel resilient multi-echelon closed-loop location-allocation-inventory problem (RMCLIP) is addressed that optimizes strategic and tactical decisions simultaneously. In order to represent the purchasing cost of raw material from the supplier, a pricing model under quantity discounts is employed in the closed-loop supply chain (CLSC). Considering the capability of returning the ...
