Summary: To the generalized hybrid information which is composed of hybrid data, multi-types weighting methods and multi-structure aggregation models, this paper studies the question of their synthetic integration and calculation method. Firstly, the generalized hybrid information is classified and integrated by the traditional decision process, and an associated information integration framework is constructed. Secondly, the solution method of this information integration framework is analyzed from the aspect of stochastic simulation, and the solution steps are summarized. Based on this, the application of this method is illustrated by the example of missile selecting, and the validity is also tested. The problem of multi-types information fusion is solved by an information integration framework, and a more flexible method for the solving of the information integration framework is developed. Therefore, this research can provide technical reference for multi-sources and multitypes information’s fusion in the field of democratic decision-making.
