Retailer observes customer demand, Dt. Retailer orders qt from manufacturer. Lead time = L. The Bullwhip Effect Var(q)/Var(D):For Various Lead Times Multi-Stage Supply Chains Consider a multi-stage supply chain: Stage i places order qi to stage i+1. Li is lead time between stage i and i+1. Formula Multi-Stage Systems:Var(qk)/Var(D) The Bullwhip Effect:Managerial Insights Exists, in part, due to the retailer’s need to estimate the mean and variance of demand. The increase in variability is an increasing function of the lead time. The more complicated the demand models and the forecasting techniques, the greater the increase. Centralized demand information can reduce the bullwhip effect, but will not eliminate it. Coping with the Bullwhip Effect Reduce Uncertainty - POS - Sharing Information - Centralizing demand information Reduce Variability Year round or Everyday low pricing Reduce Lead Times - Information lead times: EDI - Order lead times: Cross Docking Alliance Arrangements Vendor managed inventory 文獻探討 長鞭效應( Bullwhip Effect) 供應鏈的變革歷程( Envolution) 供應鏈之績效衡量 ( Measure Performance) 供應鏈作業參考模式( Supply Chain Operations Reference Model) 供應鏈的下一步( Six Sigma / SCOR/ Lean) 文獻探
