Abstract
The existing network risk control mechanisms are lack of scientific and normative decision-making and rely too much on subjective judgments, which brings a great uncertainty on network risk management. In this paper, a risk control decision-making mechanism of power data network based on grey relation is put forward, and puts emphasis on the prior risk control based on the prediction results. This mechanism first constructs a matrix of positive and negative ideal measures according to the risk control objective. Then, the grey relation coefficient matrix between the candidate and ideal measures is calculated to evaluate the similarity between measures. Finally, we define the grey relation projection coefficient to evaluate the degree of closeness between the candidate measure and the positive ideal measure and the degree of deviation between the candidate measure and the negative ideal measure. Simulation results show that this mechanism can make timely and accurate decision-making of network risk control measures.
