Research On The Inventory Sharing And Optimizing Of Aviation Equipment Parts Based On Virtual Inventory Management

With the development of the economic globalization, the freight volume of our aviation industry increased dramatically, the competition among air transport companies in our country became further exacerbating.The competition reflected not only in the innovation of management mode but also in the control of the management cost.When the new-bulid air transport companies completed the transformation of Market under the severe internal and external environment,how to get the points of the method to innovate the management mode and control the rising cost to improve enterprise core competitiveness in management and operation level.It has become the most fiery topic to make so mang scientists to disscuse.By controlling inventory costs effectively and enhancing the aviation equipment parts turnover, it has been proved to be effective breakthrough during the exploring of the aviation parts management. Generally, the aviation aircraft holded a large amount aviation parts and built maintenance hangar to keep the operation and maintenance of the fault parts replacement. But it leads to a random demand and a huge inventory network which is full of the complexity.The theory of virtual inventory managent is based on distributed network inventory sharing and optimization.lt suites to solve the problem one inventory muilt-levels involved in the principal role, the overall demand for spare parts inventory and more shared optimization. At the sane time, its flattened loose structure suites to build the business models of air spares network.This article applies the virtual inventory management theory to the Inventory management sharing and optimizing, proposes the mode of aviation equipment parts inverntory sharing and optimizing, designes the corresponding business processes. Based on the queuing theory and METRIC-model, the article built the mode of aviation equipment parts inverntory sharing and optimizing.Under the system service level to protect the supply of spare parts, the model establish overall minimum-cost optimization goal.Then, the article combines the PSO and MATLAB software to calculate the total cost of the two models which is the shared and non-shared system.
