The purpose of the present study was to investigate bullwhip effect on various stages of supply chain and changing inventory control parameters. The results were investigated step by step. To this end, four variants of the main supply chain model were explored and the obtained results were put in bullwhip effect. In the study, we employed a combination of Arena high-level simulation tool and Java programming language to simulate the model. As we observed, bullwhip effect and lead time, periodic review and safety time were directly 58.19, 120.7 and 1498.57%, respectively. Forecast window was the only variation which had a good effect (14.98%, reversely). Regulating these parameters can lead to promising results regarding bullwhip effect and identify the best combination of parameters which lead to the least change in order.
