关 键 词：D/S theory fuzzy number BPA 

摘      要：There exists lots of fuzzy and imprecise information with the development of society and *** to combine and evaluate these information becomes *** paper takes the proportion of the membership function values into consideration and makes use of each interval area value compared with the whole area of fuzzy number to measure the distribution of the membership function values.A triangular membership function was used to represent the fuzzy ***,the BPA of each point selected can be gained through multiplying the membership function values with their proportion *** last,the D/S Theory was used to aggregate the fuzzy *** an instance,we get an acceptable result.
