Network Security Situation Assessment Method Based on Absorbing Markov Chain

Evaluation for space frequency and orbit resources using EWM-AHP

“…Number of 0 degree orbital intervals need to be coordinated Number of (0,0.5] degree orbital intervals need to be coordinated Number of (0.5,1] degree orbital intervals need to be coordinated Number of (1,2] degree orbital intervals need to be coordinated Number of (2,3] degree orbital intervals need to be coordinated Number of (3,5] degree orbital intervals need to be coordinated Number of (5,7] degree orbital intervals need to be coordinated Number of (7,+inf) degree orbital intervals need to be coordinated Table 4 Results of the search 0 (0, 0.5] (0.5, 1] ( The eight tertiary indicators are all negative indicators since more SFOR need to be coordinated, which makes coordination more difficult. The raw data are normalized using Equation (3) to produce the normalization matrix that is shown in Table 5.…”

“…Through the feature analysis of satellite network coordination factors and the use of a convolutional neural network as an algorithmic model, Gao [3] proposes a satellite network orbit evaluation strategy based on a machine learning algorithm for satellite network coordination analysis and resource reserve. Zhou [4] evaluates and analyzes the frequency and orbit information corresponding to the demand band using the AHP method and a fuzzy integrated evaluation approach with a one-vote multiplicative factor.…”
