During information fusion of sensors

sometime object should be observed from different aspects

the goal of data fusion is discriminating the belonging type of the research object.Based on the theory of statistic analysis

coefficient of variance is used

a new fusion arithmetic for fuzzy sensor data is proposed.The method needn’t assume the distribution function

needn’t define the relationship matrix influenced by subjective factor.It can make full use of data and avoid losing the important extreme data

and make the conclusion more suitable for the practice.The simulated experiment shows that the algorithm is not only very efficient but also simple.
