Query: Bullwhip effect attenuation in supply chain management via
  control-theoretic tools and short-term forecasts: A preliminary study with an
  application to perishable inventories   Supply chain management and inventory control provide most exciting examples
of control systems with delays. Here, Smith predictors, model-free control and
new time series forecasting techniques are mixed in order to derive an
efficient control synthesis. Perishable inventories are also taken into
account. The most intriguing "bullwhip effect" is explained and attenuated, at
least in some important situations. Numerous convincing computer simulations
are presented and discussed.
