Abstract

China's forestry is in a critical period of transition from traditional forestry to modern forestry and forest products industry is in a boom period. Forestry logistics research is the weak link in the current logistics research areas, thus strengthening forestry logistics research has important significance. At present, the number of forest industrial enterprises increasing number of intense competition every year, combined with wood instead of material development, exacerbated by the extent of its competitive, showing uncertainty, diversity and dynamic user demand, resulting in many forest workers enterprises are facing a test of survival. Thus, the forest industrial enterprises and how to adapt to the market impact and seek their own development innovation has become the top of the agenda of the current business and researchers. Inventory management of the supply chain as a state-of-the-art management techniques can significantly improve business performance and improve the management level, and by the extensive attention of academia and the business community. Thus, the positioning of the main object of study in the forest products industry supply chain inventory control mode, as the research method and system dynamics theory. This paper briefly describes the system dynamics theory, and discusses the feasibility of its application in the supply chain, inventory control. The then macro perspective, the analysis of the market of the industrial forest workers living environment - timber supply and demand relationship, forecast supply, demand, and price trend of the three. Finally, in the context of the macro environment, from the microscopic perspective of depth the main body of the forest-industries - wood processing enterprises, analysis of its operating environment, build traditional inventory management model (Customer Managed Inventory, CMI) and vendor-managed inventory mode (Vendor Managed Inventory VMI) dynamic model and simulation are two modes in the case of different needs, the actual operation of comparing two modes different impact on the level of business inventories. In this paper, the method of model building using the system dynamics modeling and analysis methods, different from the traditional pure mathematical modeling method. Through the establishment of the system flow diagram, statistical or empirical methods to quantify the causal relationship, thereby establishing a series of system dynamics equation model validity test run last simulation inventory system. This method makes clearer the internal structure of the inventory system, the interaction between the various factors, the mutual influence of the causal relationship is becoming better known, but also to avoid the excessive pursuit of the \Of this use of the basic principles and methods of system dynamics simulation study of the forest products industry supply chain inventory control mode, a new attempt to forestry logistics research. Understanding of the logistics of forestry is a deepening of the process of modern forestry logistics system still need to further improve for forestry logistics research, the future has yet to be further explored.
