The Research Of SD Model Of Commodity Price Based On Supply Chain

Price is the traditional economic levers and the key elements of modern marketing theory of 4P. The change of Price has an important impact on production, consumption and formulation, implementation and adjustment of economic policy. Depth study and govern the laws of commodity prices operation, find and grasp its trend, it is of great practical significance to effectively enhance the ability to regulate and control the price. This article mainly studies the effect of inventory on commodity prices, using the way of system dynamics to analysis the line of the movement of commodity prices in the dynamic, establish a system dynamics model of commodity prices in supply chain, and use the example to simulation and analysis.After describing the background and significance, and limiting the study scope and study subjects. This paper firstly introduced the related theories of research. As the main content of the paper, in this part, using the theories of supply chain, inventory and price and system dynamics for establishing model of commodity prices in three different modes supply chain. After that, the author simulates the model with example, comparing the price fluctuations situation in different modes of supply chain management. Finally, the writer finds the measures to make the price more stable through the simulation.
