Abstract: This paper studies density operator of blended data information form by using stochastic simulation method on the basis of Monte Carlo simulation. First, the blended data are transformed into interval numbers, which are in the same scope after parallel translation and enlargement or contraction. Then, the stochastic numbers are given through stochastic number generator, which obeys some distribution. A clustering method and density weights determination method are provided. Based on this, the stochastic simulation method is used for information aggregation model of density operator, which can generate conclusion with reliable information. At last, an example is given to illustrate the effectiveness of the proposed method.
