On the Bullwhip Effect Measure in Supply Chains with VAR (1) Demand Process
International Journal of Industrial Engineering and Production Research, 2008 In this paper, a two-echelon supply chain, which includes two products based on the following considerations, has been studied and the bullwhip effect is quantified.

International Transactions in Operational Research, Volume 33, Issue 3, Page 1971-2015, May 2026.Abstract In most blood supply chains, blood centers and hospitals make individual decisions, resulting in an inefficient structure of the blood supply chain, which in turn renders supply and demand matching a challenging exercise. In this work, we make the very first attempt to optimize the interaction between blood centers and hospitals.

Exploring the Bullwhip Effect and Inventory Stability in a Seasonal Supply Chain
International Journal of Engineering Business Management, 2013 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.

Speculative Bubbles and Control Theory—An Endogenous Approach
System Dynamics Review, Volume 42, Issue 2, April/June 2026.ABSTRACT Speculative bubble formation has been a long observed feature of markets, and continues to be a major focus of behavioral finance, economics, marketing, and operations management research. While these bubbles arise from specific physical or informational features of specific markets, their formation is also driven by the interplay between ...

Supply Chain Disruptions and Retail & Wholesale Inventory Dynamics: An Empirical Investigation
Transportation Journal, Volume 65, Issue 2, Spring 2026.ABSTRACT Effective inventory management is critical for retail and wholesale (R&W) firms. Yet, little is understood regarding R&W firm‐level inventory dynamics during supply chain disruptions. Such dynamics have implications for transportation providers tasked with hauling these goods.

SIMULATED CHAOS IN BULLWHIP EFFECT
Pressacademia, 2015 The main purpose of the research is to investigate nonlinear dynamics in bullwhip effect and search chaotic behavior. In the paper, a generalized supply chain model is simulated with safety stock regulations to expose the bullwhip effect. A seasonal demand model which fits Poisson distribution is utilized to generate orders from customers to retailers,
