Supply Chain Bullwhip Effect And Anti Bullwhip Effect Analysis Under The Optimal Inventory Policy

摘要

Member of the supply chain determines the optimal order amount and inventory;according its downstream demands.Its rational choice is to minimize the total cost of inventory.This paper assumes supply chain membe~adopt the optimal inventory policy.The meas~ement ofbullwhip effect is the ratio of order variance to demand variance.Totally when demand correlationcoefficient and order lead time increase，the bullwhip effect in the supply chain has becomeobvious.But in a certain interval of demand correlation coefficient and order lead time.there isanti bullwhip effect phenomenon.This study obtained this interval through numerical example andsensitivity analysis.
