The bullwhip effect (amplification of order variance from a downstream stage in a supply chain to an upstream stage) is widely observed in practice, and is generally considered a major cause of supply chain inefficiencies. But are supply chains always better off with strategies that are designed to dampen the bullwhip effect? This paper considers a model where a single product is sold through m...

Partnerships, alliances and Efficient Consumer Response (ECR) are concepts that have been prominent in the marketing and logistics literature in the 1990s. One element of relationship building between vendor and purchaser is the outsourcing of activities within the supply chain. Although outsourcing was one of the topics discussed in the major retail trade conferences in the US (National Retail...

Radio frequency identification (RFID) is an automatic identification technology making its way to supply chains in Retail, Pharmaceutical, and other industries. RFID extends the reach of supply chain information systems in such a way that it will soon be possible and economically feasible to tag valuable physical objects and then to track and trace them, enabling many novel and useful applicati...

In order to manage medicine distribution in an appropriate manner, there is a necessity of deep understanding of its management. The challenges of the pharmaceutical products supply chain are its specified shelf life and specified storage conditions. Managing quality of medicines during distribution is a critical operation. There are various dosage forms of medicines eg tablets, syrups, injecta...

Supply chain phenomena such as the bullwhip e.ect and boom and bust have been widely studied. However, their interaction with other factors has not been elaborated. We use scenario-based dynamic simulations to study the short product life cycle case, exempli2ed by TamagotchiTM, which was the 2rst of the virtual pet toys. Our model has three components, market, retail and factory. To simulate th...

We consider a series of companies in a supply chain, each of which orders from its immediate upstream collaborators. Usually, the retailer's order do not coincide with the actual retail sales. The bullwhip effect refers to the phenomenon where orders to the supplier tend to have larger variance than sales to the buyer (i.e. demand distortion), and the distortion propagates upstream in an amplif...
