摘要
研究了在电子商务环境下产品存在现货市场时,由供应商和制造商组成的两层供应链网络在两阶段交易情况下的均衡问题。模型考虑了供应链同一层次企业间存在竞争和不同层次企业间存在交易成本的情况,研究了两阶段交易网络均衡问题,建立了供应商和制造商的决策模型,给出了求解算法并做了算例分析。求解得到的均衡产量、订货量和均衡价格对供应链上企业决定生产规模和销售价格等,均有指导意义。
A two- phase supply chain network equilibrium model was developed in which both physical and electronic transactions could be conducted, and this supply chain network consisted of two layers of suppliers and manufacturers.. Competitions between enterprises in the same tier and transaction cost among enterprises in different tier of supply chain were taken into consideration in this model. Based on these considerations, equlilibrium of two-phase transaction model was studied. Decision-making model for both suppliers and manufacturers were constructed. Solution algorithm to this equilibrium problem was presented and computation examples were analyzed. Equilibrium output, order volume and equilibrium price derived from the proposed algorithm would be helpful for enterprises in supply chain.
