Quantifying 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...
متن کاملOn the Bullwhip Effect Measure in Supply Chains with VAR (1) Demand Process
In this paper, a two-echelon supply chain, which includes two products based on the following considerations, has been studied and the bullwhip effect is quantified. Providing a measure for bullwhip effect that enables us to analyze and reduce this phenomenon in supply chains with two products is the basic purpose of this paper. Demand of products is presented by the first order vector autoregr...

متن کاملSystematic Risk and the Bullwhip Effect in Supply Chains∗
The variance of demand can be divided into two components, a systematic risk component that occurs due to economic factors, and an idiosyncratic noise component. Operational hedging addresses the total variance of demand, whereas financial hedging is useful against systematic risk. We investigate the systematic risk component of demand uncertainty using industry-level data for the manufacturing...
متن کاملReduction of the Bullwhip Effect in Supply Chains through Speculation
Agent-based simulations show that some kinds of speculators are able to stabilize the price in a market and to make this market more efficient. Instead of a single market, we consider a supply chain comprising a sequence of three markets in order to check that such speculators can also stabilize a supply chain. Specifically, we verify if these speculators reduce the price fluctuations caused by...
