This paper examines the impacts of three factors include the service, price, and discount on the supply chain’s profit. We consider a supply chain, including one traditional retailer and two manufacturers. By using the game-theoretic approach, we d

Metal–organic frameworks (MOFs) are combinations of metal ions or clusters accommodated to organic ligands to shape different dimensional structures. MOFs are considered as a subclass of coordination polymers, with the possible characteristics that
