The effect of rare earth metals on mechanical and corrosion properties of 7085 aluminum alloy (Al-7.5Zn-1.5Mg-1.4Cu-0.15Zr) was investigated by means of optical microscopy (OM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Intergranular, exfoliation corrosion, hardness, tensile test and electrical conductivity test were performed Al alloys on both with and without...
Most of studies of supply-chain uncertainty just consider the demand or supply. This paper adds to this growing literature from operating uncertainty aspect by investigating two-stage supply chain system with one supplier and duopoly manufacturers, which supplies substitutable products. Above all, we introduce a quantity discount pricing model to address equilibrium of supply chain coordination. Then,...
In this paper, we investigate a two-stage supply chain consisting of a TPLSP and two competitive manufacturers. The common logistics outsourcing contract can coordinate the supply chain but has strong limitations. To solve this problem, we turn to the revenue-sharing contract. The dynamic game model demonstrates that this contract can coordinate the supply chain. Moreover, we discuss the revenue-sharing...
