摘要
牛鞭效应是指供应链中的需求扭曲现象。通过消除或控制这种影响，就有可能提高产品的盈利能力。本文主要研究了基于系统散度的单产品一级供应链的牛鞭效应控制技术，并在此基础上采用了从上到出(order - up - to, OUT)订单策略。首先分析了牛鞭、供应链稳定性和总成本三者之间的关系。其次，应用基于发散的控制策略稳定供应链动态，显著降低总成本(> 30%)，并在相关情况下降低牛鞭效应。
Stability Control in a Supply Chain: Total Costs and Bullwhip Effect Reduction
The bullwhip effect refers to the phenomenon of demand distortion in a supply chain. By eliminating or con- trolling this effect, it is possible to increase product profitability. The main focus of this work is to apply a control tech- nique, based on the divergence of system, to reduce the bullwhip effect in a single-product one echelon supply chain, in which an Order-Up-To (OUT) order policy is applied. First the relationships between bullwhip, stability of the supply chain and the total costs are analyzed. Second the divergence-based control strategy is applied to stabilize the supply chain dynamics with a considerable reduction of the total costs (> 30%) and, in relevant cases, of the bullwhip effect.
