Stability Control in a Supply Chain: Total Costs and Bullwhip Effect Reduction
The bullwhip effect refers to the phenomenon of demand distortion in a supply chain. By eliminating or controlling this effect, it is possible to increase product profitability. The main focus of this work is to apply a control technique, based on the divergence of system, to reduce the bullwhip effect in a single-product one echelon supply chain, in which an Order-Up-To (OUT) order policy is a...
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 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 کاملMeasuring and Analyzing the Bullwhip Effect in a Two-Product and Two Echelon Supply Chain Using Control Theory Approach
Coordination is very important in supply chain management and it is one of the main factors in supply chain profitability. Bullwhip effect is one of the basic obstacles to achieve coordination in supply chains and reduction of this phenomenon has an important role in supply chain harmony. The other side, costs of supply chain can be mitigated and customer service level can be increased by reduc...
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...
