在考虑产品寿命次数的基础上,研究了由多个制造商和多个消费市场组成的闭环供应链网络的多期动态均衡问题.采用变分不等式和互补理论获得了制造商和消费市场的最优性条件,进而建立了整个闭环供应链网络的均衡模型.采用定步长的修正投影收缩算法对模型进行求解,通过算例将不同寿命次数结合有关参数对网络均衡状态的影响进行了对比分析,给出了政府有关部门和供应链网络中制造商作决策时需关注的关键问题,本文所得结论为开展相关领域的研究提供一定的借鉴.
Based on the number of product lifetimes, the multi-period dynamic equilibrium problem of closed-loop supply chain networks consisting of multiple manufacturers and multiple consumer markets is studied. The variational inequality and complementary theory are used to obtain the most And then establishes the equilibrium model of the whole closed-loop supply chain network.The fixed projection shrinkage algorithm with fixed step size is used to solve the model, and the effect of different lifetimes with related parameters on the equilibrium state of the network is analyzed by examples , Gives the key problems to be paid attention to when the government departments and the manufacturers in the supply chain network make decisions. The conclusions obtained in this paper can provide some reference for the research in related fields.
