摘要
利用空间价格均衡理论和两层规划理论研究了由供应商和需求市场构成的两级供应链网络,构建了具有变分不等式约束形式的两层供应链网络模型,该模型既能反映同层成员间的非合作博弈关系,又能反映上下层之间的所具有的均衡性,通过算例分别分析了决策函数在对称和不对称情况下的均衡解,并给出了经济解释。
In this paper, using pricing equilibrium theory and method of bilevel programming, a bilevel supply chain network model with variational inequality constraint is constructed. The model not only reflects non - cooperative game of the same layer leaguer but also reflects equilibrium of the superstratum and substratum. The equilibrium solutions are analyzed through a given example in symmetry and asymmetry, respectively, and, the economic interpretations are presented.
