| Abstract | Bullwhip effect is a phenomenon that information transferred in the form of orders from the down stream members to upstream members in a supply chain tend to be distorted, and hence, misguide upstream members in their inventory and production decisions. Yet, in different supply chain models, the bullwhip effect behaves in a different way. In this research, I have developed a simulation model by using @Risk software to investigate the influence of some parameters, such as mean of demand, standard deviation of demand, and order quantity, on the bullwhip effect in a simple two-stage supply chain with one supplier and one retailer in which the supplier employs the reorder point-order quantity inventory (),QR policy, and the demand is assumed to be identically and normally distributed. The model has been tested with different combinations of parameters, i.e.,,,ddQμσ, and the results show that the reorder point-order quantity inventory (),QR policy usually results inhigh values of bullwhip effect observed in most cases. |
