Li (2012) advocated that limited information sharing increases the difficulty of reducing the bullwhip effect and leads to inefficient supply chain management. His research work explored new ways to reduce the bullwhip effect in supply chain systems that face uncertainties with respect to information sharing. Yungao et al. (2012) presented a

Consistent with studies in the literature, an elec-tronic linkage refers to an interﬁrm linkage enabled by an electronic medium (Bakos 1991), including both 1 The bullwhip effect is a supply chain phenomenon because it involves both buyers and suppliers in a supply chain.

upstream the supply chain is amplified at each tier and yields in stock level graphs that look like a bullwhip. Although identified and formalized over 50 years ago, this effect is still frequently discussed [ 4, 9, 10]. Methods for mitigating supply chain disruptions are manifold, but most focus on organizational aspects of the production

key technical challenges of mitigating the Bullwhip effect can be observed as follows. 1.1. Technical challenges 1.1.1. Quality of demand information The Bullwhip effect can be mitigated by reducing the inventory variance (Dejonckheere et al., 2002, 2003) which is achieved through a non-smoothed demand pattern (Dejonckheere et al.,

Behavioral Causes of the Bullwhip Effect and the Observed
the bullwhip effect and under-weighting still occur when all operational causes are removed (i.e., when the demand distribution is stable and known to chain members). Subsequent researchers have used the Beer Distribution Game to test various strategies for reducing the bullwhip effect (e.g., Kaminsky and Simchi-Levi 1998, Gupta et al. 1998).

bullwhip effect is considered as the target objective function where the demand variance equals the order variance (= no bullwhip effect occurs). For optimization and bullwhip reducing purposes one and/or two smoothing parameters, and a factor for calculating the safety stock are used. These are considered as decision input parameters. SC

demand. In other words, the manufacturer would face demand variability identical to the retailer s. However, under certain conditions, the manufacturer s demand variability can be much larger than the retailer s. This phenomenon is called the bullwhip effect and was first observed in Procter and Gamble s diapers business.

well-suited to respond to changes in aggregate demand, thus mitigating the business cycle. Pipeline infrastructure also relieves pressure on other forms of transportation, such as rail and truck (highway use, etc.), and enhances the supply chain by reducing what is often referred to as the bullwhip effect
and inventory variance amplification in a closed-loop supply chain. We adopt a difference equation math approach for analysing a closed-loop supply chain. Results show how the return flow positively affects both the inventory variance and the bullwhip effect independently of the number of echelons. On the contrary, an increasing

makes much variance in demand through the SC upward stages of a company especially at the time of festivals. This variance of demand compels the manufacturers for the extra production & supply up to the retailers. Most of the times these supplies are counted as the redundant/unnecessary supply that occurs as a manufacturer s compensation.

VMI can reduce the Bullwhip Effect, an S&RL system could provide similar benefits in the field of military logistics. Finally, although information sharing reduces the Bullwhip Effect and improves supply chain performance, military communications networks are limited. So, we must also look at ways to reduce reporting volume.

The Bullwhip Effect The variability of replenishment orders tends to increase as one moves up the supply chain, causing the bullwhip effect (Figure 1). The presence of the bullwhip effect in supply chains leads to severe consequences such as stock outs, low service level, and extra transportation and capacity costs. Lee et al.  identified five

One of the main causes of additional costs within supply chains is the bullwhip effect (Lee et al., 1997). Bullwhip effect occurs when the variance of orders placed happens along a supply chain.

In this research, centralized and decentralized model predictive control strategies are applied to control inventory posi-tions and to reduce the bullwhip effect in a benchmark four-echelon supply chain.

The Influence of Retailer Enterprise Marketing Information
The bullwhip effect (Forrester 1961; Lee et al., 1997) has been studied extensively because of its ability to explain the situation of inventory in supply chain. Bullwhip Effect involves risk to manufacturers since it is concerned with the amplification in order-size variance for upstream node in a supply chain (Lee et al., 1997).
