The closed-loop supply chain considers conceptually the possibility of reverse logistics with use recycling, remanufacturing and disposal centers. This study contributes for first time a green framework ventilators, which are highly important in case COVID-19 pandemic. proposed model simulates Iranian medical ventilator production. includes environmental sustainability to limit carbon emissions...

design of a logistics network in proper way provides a proper platform for efficient and effective supply chain management. this paper studies a multi-period, multi echelon and multi-product integrated forward-reverse logistics network under uncertainty. first, an efficient complex mixed-integer linear programming (milp) model by considering some real-world assumptions is developed for the inte...

in this research, we address the application of uncertaintyprogramming to design a multi-site, multi-product, multi-period,closed-loop supply chain (clsc) network. in order to make theresults of this article more realistic, a clsc for a case study inthe iron and steel industry has been explored. the presentedsupply chain covers three objective functions: maximization ofprofit, minimization of n...

The rapid advancements of Information Communications Technology (ICT) are leading to extreme improvements in computing power and to the design and development of innovative products and new improved versions of the existing ones. As a result, ICT products become obsolete more quickly and in increased quantities resulting to ever-increasing waste of electrical and electronic equipment (e-waste)....

in this paper, firstly by using a mixed linear programming a new model of locating facilities with limited capacity is presented to design a closed-loop supply chain in a multi-product and multi-period mode. then, using a robust optimization approach, the proposed model decreases in non-deterministic expansion. the results show that the proposed model can handle facility capacity in a closed lo...

Environmental problems are recognized as one of the most serious issues in these last few decades. Green supply chain management and sustainable supply chain management have gained increasing attention within both academia and industry. Previous studies proposed a closed-loop supply chain model and a negotiation protocol for increasing the amount of reused products and reducing waste products. ...

Nowadays, researches pay more attention to environmental concerns consisted of various communities. This study proposes a multi-echelon, multi-period closed-loop supply chain (CLSC). A comprehensive model considers the selection of selection of technology and environmental effects. The supply chain is under a build-to-order (BTO) environment. So, there is not a final product inventory. Also, th...

Remanufacturing is an industrial process that makes used products reusable. Remanufacturing is a way to establish a closed-loop supply chain. One of the important aspects in both reverse logistics and remanufacturing is pricing of returned and remanufactured products (called cores) that it has been noticed in this paper. In addition, in this paper the researchers have tried to present a mathema...
