Measuring and avoiding the bullwhip effect: A control theoretic approach
An important contributory factor to the bullwhip effect (i.e. the variance amplification of order quantities observed in supply chains) is the replenishment rule used by supply chain members. First the bullwhip effect induced by the use of different forecasting methods in order-up-to replenishment policies is analysed. Variance amplification is quantified and we prove that the bullwhip effect i...

A New Approach For The Bullwhip Effect
Supply chains in industry have a very complex structure. The influence of many parameters is not known. Therefore the control of the orders, material flow and stock is rather difficult. In order to recognize the basic relationships between the parameters, a very simple model was set up. It consists of 4 identical stages. In all stages the stock is closed-loop controlled to a nominal stock. Ther...
