Evidence Modeling Based on Sensor Credibility

To deal with sensor reliability in evidence modeling, the sensor credibility is evaluated by means of the statistical characters. Then an evidence model based on sensor credibility is established. When modeling, plausibility discount strategy is used to integrate the credibility into the evidence model. The total uncertainty of the evidence model decreases. The simulation example shows that the method of evaluating the credibility is generic and effective, and the evidence model based on sensor credibility gives more reasonable result and improves the decision-making accuracy.
