Superior supply chains are one of the best ways to compete in today's marketplaces. In Supply Chain Management, overall supply chain evaluation needs to include an important logistical effect known as the Bullwhip Effect. It shows how small changes at the demand end of a supply chain are progressively amplified up the supply chain. Production plans are based on demand forecasting and suppliers ...

T bullwhip effect is a major source of supply chain inefficiency. Whereas prior literature has identified a number of potential contributing factors and recommended such remedies as information sharing enabled by information technology (IT) or electronic linkage (EL), few studies have provided empirical support. We use industry-level data to examine whether EL use with buyer and supplier indust...

This paper proposes an adaptive fuzzy control application to support a vendor managed inventory (VMI). The methodology applies fuzzy control to generate an adaptive smoothing constant in the forecast method, production and delivery plan to eliminate, for example, the rationing and gaming or the Houlihan effect and the order batching effect or the Burbidge effects and finally the Bullwhip effect...

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...

Supply chain management (SCM) aims to efficiently integrate suppliers, manufacturers, warehouses, and retailers, not merely to ensure that merchandise is produced and distributed in the appropriate quantities, to the right locations, and at the right time, but also to minimize system wide costs while satisfying customer requirements. With global transnational enterprise layout trend, data consi...

This paper provides an assessment on the impact of collaboration and smoothing replenishment rules on supply chain operational performance and customer service level. Three supply chain configurations (i.e. Traditional, Information Exchange and Synchronised) in which orders are generated by smoothing (S, R) inventory control policies, are studied for variations of proportional controller for di...

We study the Damped Trend forecasting method and its bullwhip generating behaviour when used within the Order-Up-To (OUT) replenishment policy. Using z-transform transfer functions we determine complete stability criteria for the Damped Trend forecasting method. We show that this forecasting mechanism is stable for a much larger proportion of the parametrical space than is generally acknowledge...

We demonstrate how bullwhip reduction principles generated through generic supply chain modelling have been used to tackle the bullwhip problem within Tesco, the largest UK grocery retailer. In the context of bullwhip research, this bridging between theory and practice has not been extensively demonstrated previously. The research involved examining the automated store ordering system, through ...

T value of information sharing and how it could address the bullwhip effect have been the subject of studies in the literature. Most of these studies used different forms of demand models, assuming that no order smoothing was used by the retailer and that the supplier has full knowledge of the retailer’s demand model and order policy. In this paper, we contribute to the literature by starting w...
