Risk evaluation of navigation environment under composite navigation model

“…Taking the Baise hub project as an example, the data of each risk factor was standardised [9][10] for comparison in order to unify the quantitative scale, as shown in Table 3. U as an example, and derive the classical domains oj R , the nodal domains P R , and the object elements to be evaluated R by using the relevant formulas, in order to better assess the risk characteristics of the project:.…”

(10) (2) According to the association coefficient formula, the association coefficient of 11 23 UU ～ can be calculated as shown in Table 4. The remaining three criterion layer correlations and the target layer risk correlation can be derived from the object element topological model solution, with the risk level being the level corresponding to the maximum correlation value.…”
