Abstract: Hierarchical division of regional national defense highway network nodes is the primary work of the layout optimization. The hierarchical division standard is different for national defense highway network compared with ordinary national highway network, thus the targets determination and method adoption are different accordingly. First, the paper defined the principle of the hierarchical division. Then, it put forward the new method of hierarchical division based on grey clustering. The paper formulated the grey clustering of whitenization weight function model, and provided an actual calculation example. The results of the example show that the proposed model is scientific and reasonable, and the calculation process is compact and easy to program. Therefore, this method can be applied in layout optimization of regional national defense highway network.

Key words: grey clustering, whitenization weight function, regional national defense highway network, highway nodes, hierarchical division
