Vendor Managed Inventory and bullwhip reduction in a two level supply chain
This paper compares the bullwhip properties of a Vendor Managed Inventory (VMI) supply chain with those of a traditional “serially-linked” supply chain. The emphasis of this investigation is the comparative impact the two structures have on the “Bullwhip Effect” generated. Particular attention is paid to the manufacturer’s production ordering activities as demonstrated using a simulation model ...
متن کاملControlling the Bullwhip Effect in a Supply Chain Network with an Inventory Replenishment Policy by a Robust Control Method
This paper develops a mathematical model using differential equations and considers a bullwhip effect in a supply chain network with multiple retailers and distributors. To ensure the stability of the entire system and reduce the bullwhip effect, a robust control method and an inventory replenishment policy are proposed. This shows that the choice of the output matrix may reduce the bullwhip ef...
متن کاملBullwhip Effect Reduction: the Impact of Supply Chain Flexibility
The study addresses the impact of flexibility on the bullwhip effect, i.e. the increase of demand variability moving upstream along the SC. With this aim, a three stages SC is investigated, where producers/suppliers/retailers are connected by appropriate inventories. A reorder quantity ROQ (constant time interval) as stock policy has been adopted. The analysis takes into consideration two extre...
متن کاملExploring the Bullwhip Effect and Inventory Stability in a Seasonal Supply Chain
The bullwhip effect is defined as the distortion of demand information as one moves upstream in the supply chain, causing severe inefficiencies in the whole supply chain. Although extensive research has been conducted to study the causes of the bullwhip effect and seek mitigation solutions with respect to several demand processes, less attention has been devoted to the ...
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 ...
