For the uncertainties of intelligence information during the multi-source information perception, based on grey system theory model, this thesis makes assessment about the ability of the multi-resource intelligence perception of joint tactical formation. The thesis also constructs multi-resource intelligence evaluation of the performance indicators of perception, using AHP to determine weights at all levels. Finally, an example to validate the results that it is feasible to use grey system theory in assessment of multi-resource intelligence perception and the conclusion is reliable.
