The Study Of Inventory Control Impact Under Demand Fluctuations For Third-party Automotive Logistics

The third-party automotive logistics in China developed rapidly with automobile industry development in recent years. The volatility of automotive Logistics demand effect logistics management, especially caused inventory control instability. It also increased in operating costs, reduce the level of logistics service.This paper introduces the status of Automotive Logistics China's third-party, on the basis of fluctuations in demand for automotive logistics classification of different types of fluctuations in the impact of factors, characteristics, influence the degree of explanation. The article establishes an ideal state of third-party logistics company car inventory control model.This paper focuses on the demand for quantitative analysis of the cyclical fluctuations in the short-period fluctuations, long-period fluctuations, non-cyclical fluctuations in demand growth fluctuations, fluctuations of the type to reduce the impact of inventory control. The article definits the inventory control function, and establishes mathematical models in view of the impact of four types of fluctuations respectively. Then it converts the time-domain problem to the frequency domain for analysis with Fourier transform and Z transform. An Empirical Analysis through a detailed analysis of the impact of four types of fluctuations, the use of frequency spectrum shows four types of fluctuation inventory control impact of the similarities and differences, and respond to different methods to avoid fluctuations.The end of this article is the summary of this paper. It makes main conclusions on the above brief summary of chapters summarizing, and the yet to be studied.In this paper, including Figure 9, Table 9, and 36 references.
