Complex equipment simulation system credibility evaluation method based on uncertainty measurement

The invention provides a complex equipment simulation system credibility evaluation method based on uncertainty measurement. The method comprises the steps that a model information interaction credibility evaluation network is constructed based on all nodes and all edges in a to-be-evaluated simulation system, the nodes are units executing a certain function in the simulation system, and the edgesare information interaction relations among all the units in the simulation system; obtaining model information interaction credibility based on uncertainty measurement to evaluate credibility of allnodes in the network; obtaining initial credibility of the simulation system based on the credibility of all the nodes and the importance degree of all the nodes; and comparing the preliminary credibility of the simulation system with the credibility range of the simulation system, and determining the final credibility of the simulation system according to a comparison result. The credibility evaluation method can solve t
