双渠道多期供应链网络均衡模型研究

Multi-period supply chain network equilibrium model with two-channel

为适应信息化和高度动态化的发展,研究了在实体和网上两种交易渠道下,由制造市场、零售市场和需求市场组成的三层动态供应链网络的均衡问题,在静态供应链网络均衡模型的基础上,考虑了库存和网上交易对供应链网络的影响。分别对制造市场、零售市场和需求市场的决策者的独立决策行为及其相互作用进行了分析,构建了各层市场的有限维变分不等式,并将变分不等式问题转化为等价的互补问题的形式,给出了经济解释,得到了最终的双渠道多期供应链网络均衡模型,并给出了算例分析。求解得到的均衡产量、交易量、库存量和均衡价格对供应链上企业的经营具有指导意义。

To adapt to information-oriented and highly dynamic development, under inventory and electronic transaction circumstance, the equilibrium problem of a three-tiered dynamic supply chain network structure consisting of manufacture market, retailer market and demand market were discussed. Based on the static supply chain network equilibrium model, effects on supply chain network from inventory and electronic transaction were considered. The independent decisions of manufactures, retailers and demand markets as well as the effect of their interactions were analyzed. The finite-dimensional variant inequality for different tiers was constructed, which was transformed to equivalent complementary problem, and the economic interpretation was also provided. Finally, the multi-period supply chain network equilibrium model with two-channel was obtained and a numerical example was provided. Equilibrium output, trade volume, inventory volume, and equilibrium price derived from the numerical example would be helpful for enterprises marketing in supply chain.
