The supply chain system grow to be foremost division of all business organizations. Each organization pays the concentration to preserve the procession among the organizations’ services. The bullwhip effect is one of the main sweats faced in soft organization of the supply chain management system. This effect can influence the superiority of the services generated by finicky association. Withou...

On the basis of the AR(1) stochastic process model for consumer demand which was introduced by Professor H.L.Lee, qualified and simulation model of bullwhip effect are established when order-up-to inventory policy is employed, which investigate demand variability caused by forecasting technology, such as moving average (MA) method, exponentially weighted moving average (EWMA) method or mean squ...

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...

Sustainable and green logistics concepts are a major trend in global supply chains. An important research question in this context is the topic of a possible interdependence between green logistics measures and overall volatility in supply chains, discussed in logistics literature e.g. as ‘bullwhip effect’. This research paper therefore tries to give an overview about existing knowledge regardi...

We consider how lead-times create the bullwhip effect in an inventory replenishment system. The inventory system is a combination of a specific demand process, a forecasting method, and a replenishment policy. Previous studies have evaluated the bullwhip effect when some of the system parameters such the forecasting model, demand process, or the lead-time are changed. This type of analyses has ...

This paper analyzes the bullwhip effect in decentralized, linear and time-invariant (LTI) supply chains. It generalizes existing results by broadening the class of policies and customer demand processes under consideration. The supply chain is modeled as a single-input, singleoutput control system driven by arbitrary demands. The paper discusses the appropriateness of various metrics for the bu...

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 ...

T bullwhip effect is the phenomenon of increasing demand variability in the supply chain from downstream echelons (retail) to upstream echelons (manufacturing). The objective of this study is to document the strength of the bullwhip effect in industry-level U.S. data. In particular, we say an industry exhibits the bullwhip effect if the variance of the inflow of material to the industry (what m...

Preface This research paper is a compulsory part of the Master's program Business Analytics at the VU University Amsterdam. The student should do research on a business related problem, with a strong mathematical or computer science component. The research could be based on literature, but may also be extended with own research. This research paper presents an elaborate literature overview of t...

The bullwhip effect as a concept has been known for almost half a century starting with the Forrester effect. The bullwhip effect is ‘‘allegedly’’ observed in many supply chains, and it is generally accepted as a potential malice. Despite this the bullwhip effect still seems to be first and foremost a conceptual phenomenon. Some even simply denies that the phenomenon exists at all in practice. ...
