资金约束下供应链牛鞭效应

Ullwhip Effect in Supply Chain Under Funding Constraints

在不同资金约束下,供应链尽管仍表现出牛鞭效应,但其效果却比资金不受限的情况要弱。如果资金约束过强,牛鞭效应将变得不显著,其关键原因在于资金受限制作为一种产能受限,虽然一方面由于这种带延迟的负反馈回路使得系统振荡行为加强,另一方面,资金由于其本身的流动性使得它同时也增加了正反馈回路的作用,这制约产生牛鞭效应的系统结构,进而弱化牛鞭效应。

Abstract:Under funding constraints,the bullwhip effect is still obvious although it tends to be weaker than it is in the normal situation.When funding constraints are severe,the bullwhip effect becomes unnoticeable,the key reason for this is: funding constraints which are regarded as a kind of production capacity constraints,serve on the one hand to strengthen the system oscillation with the delayed negative feedback loop,while on the other,the mobility of capital intensifies the positive feedback loop in the system.This mechanism impacts the system structure of bullwhip effect and thus weakens the bullwhip effect.
