摘要
文中采用模糊数集来描述先验信息,用模糊贴近度来衡量先验信息的可靠性,给出了可信度的计算公式,将其以权阵的形式纳入参数估计中,以平衡不同可信度的先验信息在参数估计中的作用。最后通过算例分析了该算法的可行性。
In this paper, the prior information was described using the fuzzy set and the reliability of prior information was measured using fuzzy closeness,and the calculate credibility of the formula was given, the obtained credibility could be constructed as a weight matrix to balance the effect of prior information with different confidence. Finally, the example analysis showed that the proposed algorithm was feasible.
