This paper proposes a robust model for optimizing collaborative reverse supply chains. The primary idea is to develop a collaborative framework that can achieve the best solutions in the uncertain environment. Firstly, we model the exact problem in the form of a mixed integer nonlinear programming. To regard uncertainty, the robust optimization is employed that searches for an optimum answer wi...

we model a real-world case problem as a price competition model between two leader-follower supply chains that each of them consists of one manufacturer and one retailer. t he manufacturer produces partially differentiated products and sells to market through his retailer. the retailer sells the products of manufacturer to market by adding some values to the product and gains margin as a fracti...

Sustainability legislation, new consumer behaviour and the complexity of global trade are increasingly changing the way of designing and managing supply chains. In this context, one should take into consideration sustainability factors, such as minimization of carbon emission, treatment of reverse flows, optimization of energy consumption; etc., simultaneously with the product’s life cycle desi...

In this paper, the competition between two supply chains and their elements is studied. Each chain consisted of a manufacturer and a distributor and the two chains compete in a market with single type of customer sensitive to price and delivery time. Therefore, this is a two-supply chain game and during the competition between two supply chains, elements of each supply chain (manufacturer and/o...

Recently, with the environmental crisis, Green supply chain management (or GSCM), and in particular closed loop supply chain model, has received considerable attention by researchers. Closed loop supply chain model aims at reduction of waste and generating profit for enterprises through integrating forward and reverse logistics. Unfortunately, there is limited research on general models for clo...

today, the global business environment compels enterprises to consider rest of the world in their competitive strategy analysis where firms ignore external factors such as economic trends, competitive positions or technology advancement in other countries. while going truly global with supply chain management, a company develops product in the united states, produce in india and trade in europe...

Environmentally beneficial reverse supply chains for chemicals, materials and devices are enablers of a sustainable future, writes Elsa Olivetti.
