The civil aircraft spare parts support network is a necessary medium for the main manufacturer to provide customers with aviation materials. The rationality of its construction is conducive to improving the service quality of the main manufacturer and the customer"s operational capability. Based on the Kriging method, this paper proposes a qualitative and quantitative combination of qualitative and quantitative methods for weighing the location factors of the civil aircraft spare parts support network. The location factors are sorted and classified, and the data requirements for quantitative analysis of the location are obtained. The aircraft material support network site selection weighs, and then the importance of site selection factors is evaluated. The validity and applicability are verified by comparing the proposed method with response surface method and Monte Carlo method. The results show that the proposed method can effectively evaluate the importance of site selection factors and lay a foundation for the construction of civil aircraft aviation materials support network.
