In this article, we presents a two-stage stochastic programming model for the problem of designing a closed-loop supply chain network which is applicable in the context of modular structured products. The model accounts for uncertainty in the quality status of the return stream, modeled as binary scenarios for each component in the reverse bill of material corresponding to such products. The st...

throughout the history, earthquakes led to not only the destruction of many homes and damage to a lot of people, but also homeless of people and in need of medical aid. one of the key issues which have always great importance during the disaster is supply the needed blood of blood units' applicant people. therefore, in this paper with the design of blood supply chain at the time of earthquake d...

Supplier selection and order allocation (SS-OA) are two of the most important strategic decisions for supply chain network design operation. If sustainability resilience criteria taken into consideration together a holistic sustainable resilient SS-OA is carried out, it may enable to perform better when subjected disruption scenarios. In this research paper, novel comprehensive multi-phase, mul...

This paper discusses the optimal pricing and collecting decisions in a fuzzy environment of three closed-loop dual-channel supply chain models where manufacturer produces original product from fresh materials unfashionable products. The sells products to customers using direct retail channels (forward dual channel). In reverse channel, manufacturer, third-party collector retailer individually t...

Along with forward supply chain organization needs to consider the impact of reverse logistics due to its economic advantage, social awareness and strict legislations. In this paper, we develop a system dynamics framework for a closed-loop supply chain with fuzzy demand and fuzzy collection rate by incorporating product exchange policy in forward channel and various recovery options in reverse ...

Maintaining the health of people during and after a disaster is one of the most important issues in disaster management. Blood products are among the essential items needed to save the human life and the lack of them may lead to significant losses in human health. In this paper a comprehensive mathematical model of blood products supply chain is presented to respond the need for blood products ...
