Research on D-GERT Model of Joint Operational Situation Assessment Based on Information Flow

Abstract

To solve the problem of inaccurate description of battlefield information changes in the process of joint system operations, this paper constructed a joint operational situation assessment D-GERT network model based on information flow, on the basis of the GERT network. And the calculation method of the threat degree, the increment of battlefield information value and the importance of network nodes were given. Finally, MATLAB was used to simulate and verify the model. The results showed that the method in this paper conforms to objective reality and can provide good method support for the commander's combat decision-making.
