The Iranian chicken industry has always been encountered to high and fluctuated chicken prices. The purpose of this article is to find the best choice to prevent chicken prices from increasing more by investments. System dynamics methodology has been used to modeling, evaluating and optimizing chicken supply chain. Considering the existing capabilities for improvement in supply chain and experts opinion, these strategies were proposed; “reduction of breeding period,” “modernization of production facilities,” “Increase in pellet feed production” and “energy conservation.” After implementing the model and testing various scenarios, strategies were prioritized based on key indicators. At last modernization of production facilities is introduced as the best strategy for the next three years.
