Abstract: In the future complex battlefield environment, objective threat level of different target types are difficult to estimate for the uncertainty of information. Aiming at this problem, an information system of threat assessment is built by the theory of granular computing. Then the knowledge in the form of minimized production rules that contain the expert experience is mined by decision logic language. Furthermore, through the analysis of knowledge uncertainty, a strategy of knowledge reasoning is put forward. In this way, the threat of multi-types targets in the complex environment can be effectively evaluated.

Key words: threat assessment, knowledge obtaining, knowledge reasoning, information system, conflict resolving
