Simulation-based Analysis of the Bullwhip Effect under Different Information Sharing Strategies
نویسنده
چکیده
This paper describes the impact of two different information sharing strategies – decentralized and centralized information – combined with two inventory control policies – min-max and stock-to-demand inventory control – on the bullwhip effect. To investigate and measure this impact, simulation models are developed using the Arena 5.0 software package for a four-stage supply chain, consisting of a single retailer, wholesaler, distributor and manufacturer. The experiments with the developed models are described and the results are analyzed.

Simulation-based Statistical Analysis of the Bullwhip Effect in Supply Chains
The paper proposes both statistical and simulation-based analysis and evaluation of the bullwhip effect in supply chains. The demand distortion, called the bullwhip effect, is considered as an important characteristic of supply chain operation stability. A mathematical justification of the stochastic demand as a cause of the bullwhip effect is discussed. Results of simulation studies to analyse...
متن کاملControlling the bullwhip effect in a supply chain system with constrained information flows
The bullwhip effect problem is one of the most important issues in supply chain management. Limited information sharing increases the difficulty of reducing the bullwhip effect and leads to inefficient supply chain management. The purpose of this paper is to explore new ways to reduce the bullwhip effect in supply chain systems that face uncertainties with respect to information sharing. We fir...
متن کاملDemand forecasting and sharing strategies to reduce fluctuations and the bullwhip effect in supply chains
Supply chain inventories are prone to fluctuations and instability. Known as the bullwhip effect, small variations in the end item demand create oscillations that amplify throughout the chain. By using system dynamics simulation, we investigate some of the structural sources of the bullwhip effect, and explore the effectiveness of information sharing to eliminate the undesirable fluctuations. E...
متن کاملRisk analysis for cooperation policies benefits in reducing the bullwhip effect in a telecom supply chain
Supply chain demand is often prone to fluctuations and instability. Known as the ‘bullwhip effect’, small variations in end-item demand create order and inventory oscillations that amplify from a downstream site to an upstream site. Applying a risk analysis approach, and assuming the bullwhip phenomenon as a constant reality, this paper will present the profits or losses that can accrue from va...
متن کاملReturns and the bullwhip effect
An almost universal assumption in the bullwhip effect modeling literature is that excess goods may be returned without restriction. We seek to determine if returns impact the level of bullwhip effect observed in a multi-stage supply chain. We build a hybrid agent/ discrete-event simulation model of a supply chain and execute it under various conditions of demand variance, lead-time variance, in...
