以变分不等式为工具建立双渠道双目标的多期供应链网络均衡模型.在传统实体交易和电子网上交易的双渠道环境下,考虑时间因素与库存变量的影响,提出由制造商、零售商和需求市场组成的三层多期供应链网络均衡问题,其中制造商和零售商均追求经济利润最大化与风险最小化的双重目标.分别对各系统成员的独立决策行为及其相互作用进行分析,得到各层决策成员的均衡条件并给出相应经济解释,推导与双渠道双目标的多期供应链网络均衡问题等价的有限维变分不等式模型.在证明其解在一定的假设条件下存在的基础上,构造数值算例以验证模型的正确性与合理性.
A dual-channel and dual-objective multi-period supply chain network equilibrium model is established by using variational inequality as a tool.Under the dual-channel environment of traditional physical transaction and electronic online transaction, considering the influence of time factor and inventory variables, it is proposed that manufacturers and retailers And the demand market, aiming at the dual goal of maximizing economic profit and minimizing the risk, both manufacturers and retailers are seeking to balance the independent decision-making behaviors of the system members and their interactions , We obtain the equilibrium conditions of decision-making members at all levels and give the corresponding economic explanations to derive the finite dimensional variational inequality inequality model which is equivalent to the dual-channel bi-objective equilibrium problem of multi-period supply chain networks. After proving that the solution is under certain assumptions On the basis of existence, numerical examples are constructed to verify the correctness and rationality of the model.
