Situation Assessment Based on Group Decision and Rule Fusion

摘要

Evidence theory is one of the main methods to achieve rule-based situational awareness. However, in the combination of multiple sources, the theory of evidence can result in paradox. To resolve this problem, a situation assessment fusion method based on group decision making and rules fusion is proposed. The method includes three stages, which are the measurement of rules importance, rules fusion based on improved evidence theory and situational decision-making. Experimental results show that this method can avoid the paradox, the fusion efficiency and accuracy is superior to existing typical method.
