Threat Assessment Algorithm Based on Weight-Variation Fuzzy Comprehensive Judgment
Cai Jia · Electronics Optics & Control · 2009
The threat assessment of air penetration vehicle is studied based on weight-variation fuzzy comprehensive judgment.Firstly,fuzzy transform and fuzzy comprehensive judgement principle,theories of fuzzy mathematics,are introduced.Then taking the Airborne Warning and Control System(AWACS) for example,six key factors related to threat level of the target are analyzed via multi-attribute decision making,and a model of threat assessment is established.Finally,an algorithm for target threat assessment is proposed on the basis of weight-variation fuzzy comprehensive judgment.Weights for each factor in this algorithm are derived from its comparative importance to the threat rule and to other factors,thus the results are more precise.The algorithm also effectively remedies the demerit of expert's subjective evaluation.Example analysis shows the effectiveness and higher precision of this algorithm.
