Managing the Bullwhip Effect
The bullwhip effect is the inherent increase in demand fluctuation up the supply chain (i.e., away from customer). Managing the bullwhip effect is minimizing the fluctuation and variation of the demand (i.e., orders from one stage of a supply chain to the next stage of the supply chain) throughout the supply chain. This paper will offer a literature review of this topic, note the key contributi...
متن کاملReturns and the bullwhip effect
An almost universal assumption in the bullwhip effect modeling literature is that excess goods may be returned without restriction. We seek to determine if returns impact the level of bullwhip effect observed in a multi-stage supply chain. We build a hybrid agent/ discrete-event simulation model of a supply chain and execute it under various conditions of demand variance, lead-time variance, in...
متن کاملPrevalence of Bullwhip Effect in Hospitals
Growing concern about health care costs in developed countries in the past two decades has spawned extensive research on the industry and, in particular, hospital management. The literature on the subject is extensive and covers a wide range of themes that include application of operational research-based tools, redesign/re-engineering of delivery systems and clinical procedures, and so forth. ...
متن کاملThe Bullwhip Effect in Supply Chain
In a supply chain the variability of the orders received by the supplier can be greater than the demand variability. This phenomenon is named bullwhip effect. Some researchers are quantified the bullwhip by measuring the differences between observed variances in the different stages of the supply chain. The bullwhip effect refers to the phenomenon of amplification and distortion of demand in a ...
متن کاملQuantifying the bullwhip effect in supply chains
Consider multiple companies operating as a serial supply chain. Within this environment, end users form the demand for the last company in the supply chain, but the demand for upstream companies is formed by the companies in the immediate downstream supply chain link. It has been shown that demand seasonality and forecast error can increase as we proceed up the supply chain. These demand distor...
