Abstract
The use of System Dynamics Modeling in Supply Chain Management has only recently re-emerged after a lengthy slack period .the propose of this thesis is to use knowledge and techniques in implementation based on recent research .At first we have given an overview of supply chain management and system dynamics and then presented a taxonomy of research and development in System Dynamics Modeling in supply chain management. In this research we have focused on a supply chain as a case study Which produce and distribute healthy products and its main company is darugar. we used System Dynamics techniques to know effective variables in our supply chain and understand how to improve its performance .we started simulation model design by explaining dynamic hypothesis and continued by creating casual loops, stock & flow diagrams and mathematical formulation .our model was tested by famous dynamics and statistical techniques and then we started to investigate causes of supply chain’s behavior by sensitivity analyses. when we understood the main factors and their interactions completely we started to suggest three policies due to supply chain indexes to improve its performance .the policies are missed sale reduction ,inventory reduction and correct information receive which all causes improvement in introduced indexes in our research .what we achieved of this research was our ability of predicting results before any changes in parameters ,relationships or structure of supply chain and it is so important due to its high degree of complicity.
