Assessment Modeling for System-of-Systems Capability in Space Information Support Based on Evidence Network
To overcome the information uncertainties in the capability evaluation of space information support system,this paper adopts the method of evidence network to carry out the modeling research.It models the structure of the evidence network with the causality diagram method to create a directed acyclic graph.Besides,the conditional reliability parameter method is used in modeling the evidence network parameters to represent the quantitative relationship between the nodes.Finally,with space navigation and positioning system as an example,the corresponding evidence network model is established and compared with the Bayesian network modeling method.The results show that the evidence network can deal with the cognitive uncertainties in the evaluation on space information support capability and verify the correctness and validity of the proposed methods.
