On the square root law for bullwhip: The case of arbitrary lead-times and AR(1) demand
We develop a model of a divergent distribution network with one distribution centre and n retailers. Each of the n retailers faces a …

The benefit of altruistic behaviour achieved by the OUT policy with unmatched proportional feedback gains in a two-echelon supply chain
We study a two echelon supply chain with AR(1) demand and unit replenishment lead-times. Each echelon of the supply chain uses …
