需求正态分布条件下基于报童模型的供应链网络均衡模型

Supply Chain Network Equilibrium Model Based on Newsvendor Model under Normal Distribution of Demand

针对不确定性需求引入报童模型到供应链网络均衡模型中,用于供应链网络中厂商的产量和价格决策。考虑到在实际生活中正态分布的更为常见性和重要性,在需求正态分布条件下运用博弈理论、网络均衡理论、报童模型以及变分不等式等方法建立了需求正态分布条件下基于报童模型的供应链网络均衡模型,研究了当需求服从正态分布条件下供应链与供应链之间的竞争行为和竞争结果。

Aiming at the uncertain demand,the Newsvendor model is introduced into the supply chain network equilibrium model,which is used for the production and price decision of manufacturers in the supply chain network.Considering the more common and important normal distribution in real life,a supply chain network equilibrium model based on the Newsvendor model is established under the condition of normal demand distribution by using game theory,network equilibrium theory,Newsvendor model and variation inequality.The competition behavior and results between supply chain and supply chain are studied under the condition of normal distribution of demand.
