五级供应链网络的建模及订货策略仿真研究

o describe the complexity and dynamic of the supply chain network operation, this paper established the modeling and simulation of five-echelon complex supply chain networks. By comparing the economic order quantity (EOQ) strategy and the minimum and maximum（s,S）strategy on the basis of simulation model, the quantity of various nodes was analyzed as well as DOS, order quantity and the bullwhip effect . Simulation results show that, because supply chain is a complicated network of multi-stage companies，enterprises take different ordering strategy has significant effect on supply chain performance. To study multi-stage supply chain network simulation is an effective approach for the whole optimization and scientific decision
