Statistical process control approach to reduce the bullwhip effect
The bullwhip effect is a pervasive problem in multi echelon supply chains that results in inefficient production operations and higher inventory levels. The causes of the bullwhip effect are well understood in industry and academia. Quantitative and qualitative solutions to attenuate this effect …

Prediction and prevention of the bullwhip effect in replenishment supply chains
… are particularly susceptible to the risks of the bullwhip effect, where demand information is distorted as it is transmitted up the chain from customers to suppliers. The information distortion leads to a sub-optimal capacity planning and inventory allocation that leads to stock-outs or excess …

Reducing the demand forecast error due to the bullwhip effect in the computer processor industry
… had large amounts of error caused by the bullwhip effect (order amplification in a supply chain). This project creates a new demand forecast model in two phases. The first phase investigated the supply chain of OEMs and Retailers. The second phase of the project used the supply chain …

Downstream automotive supply chain simulation: A system dynamics approach to improve performance
… and fluctuations commonly known as (Bullwhip Effect) have been existing and is known for many years as a problem for companies. The bullwhip effect is an occurrence indicating a situation where there is an amplification of demand fluctuations as orders move upstream from customers to …

Algorithmic intervention to mitigate inventory and ordering amplification in multi-echelon supply chains
The 'bullwhip effect' is a classic, yet persisting, problem with reverberating consequences in inventory management and refers to how forecast errors and safety stock builds yield increasing amplitudes in both orders and on-hand inventory positions the further one moves away from a source of order …

Designing a strategic sourcing process for low volume, high technology products
… business cycle that follows the traditional bullwhip effect - that is, companies further up the supply chain see greater demand variability. As an equipment provider, Axcelis is positioned relatively far up the supply chain and therefore, managing these business cycles is an important …

Forward buying of non-commodity consumer goods
… in a system dynamics model that simulates the bullwhip effect.

Strategic Technology Planning Using Roadmaps in the Value System
… planning process is analogous to the ""bullwhip effect"" in supply chain management (SCM). Therefore, a solution approach similar to the one in SCM was applied. Specifically, research was done in quantifying and modeling this issue, which in this research work it received the name of …

Computerized beer distribution game management flight simulators : a review
The Beer Game has been used to demonstrate the bullwhip effect often observed in supply chains, i.e. the amplification of demand variance upstream in the supply chain in multiple echelon systems. In recent years, computerized Beer Games have been developed at a number of schools to facilitate or …

RFID in the Retail sector: A Bibliographic review of the literature
… some of those problems could be explained by the bullwhip effect or problems in the replenishment policies, such problems are also known as Inventory Record Inaccuracy (IRI), which complicates supply chain management and intensifies inventory losses both materially and financially. To mitigate the …

Beyond Firm Boundaries: Exploring The Interdependence Between Supply Chain Partners
… that focus on an in-depth examination of the bullwhip phenomenon, a study of dyadic bargaining power relationships, and finally an analysis of dyadic financial and inventory performance.</p> <p>Even though a growing body of research has sought to empirically authenticate the existence of the …

Optimizing beer distribution game order policy using numerical simulations
… is uncertain. In this thesis, I analyzed the bullwhip effect in supply chain management using the MIT Beer Distribution Game. I also proposed heuristics and models to optimize the MIT Beer Distribution Game order policy when the customer's demand is both known and unknown. The proposed model …

Building operational excellence in a multi-node supply chain
… "launch-and-expedite" behavior with detrimental effects on operational efficiency. It also demonstrates how it is possible, for an organization that finds itself in such a state, to apply basic operations principles and a data driven approach to systematically get out of the "launch-and-expedite" …

Information Network Design for Lean Logistics
… been limited to explaining phenomenon like the bullwhip effect, and for policy development. We provide a structured approach for policy design, which doesn't rely on any simulation experiments. Further, we study the impact that information network design has on the response of supply chains. We …

RFID-enabled supply chain replenishment
… and software infrastructure could mitigate the bullwhip effect, reducing inventory and improving on-shelf availability rates throughout the entire supply chain. Since this technology is still in the ferment stage of its AIDC lifecycle, Unilever and other industry players are unclear about the …

Balancing product flow and synchronizing transportation
… increase cross-dock productivity, and reduce bullwhip effect upstream in the supply chain. This thesis develops an analytical framework to calculate this steady flow. The determination of eligible SKUs in this approach is performed by analyzing each SKU's historical and forecasted demand. The …

Reducing variations in a highly constrained environment in order to increase production capacity
Variations and the negatives effects it causes on production capacity and planning are topics of significant interest in the manufacturing communities. This research investigates the hypothesis that, when operating in a highly constrained environment, capacity can be gained by reducing the …

A natural language processing approach to improve demand forecasting in long supply chains
… to improve demand forecasting and reduce the bullwhip effect, but it is infeasible to do so effectively in a long supply chain. Using the polystyrene industry as a case study, this thesis explores the usage of modern natural language processing (NLP) techniques in a deep learning model, known …
-
An analysis of engine assembly and component production behavior
… with less variability amplification from the bullwhip effect. Demand Flow Technology is introduced as a means to then affect the entire supply chain, including supporting functions not directly related to manufacturing.

Evaluating demand planning strategy in the retail channel
… the visibility of true demand, resulting in the bullwhip effect. Better collaborative processes such as S&OP and CPFR can improve the channel forecast accuracy, inventory levels, on time delivery, and sales revenue. The personal computer industry has become commoditized; promotions and price have …
