摘要
基于粗糙集理论中信息量的概念提出了一种新的主观定权法,再以优化理论为依据建立了综合定权的优化模型,并给出了模型的精确解,据此推导出了一种兼顾主观偏好和客观信息的综合权重赋值法,最后给出了一个应用实例说明了这种定权方法的有效性.
A new subjective weighting method based on rough sets is present first. Secondly, an optimization model of synthetic weighting based on optimization theory is established, and an accurate solution of the model is given. According to the model, a method to determine the synthetic weights that includes both subjective favoritism and objective information is deduced. Finally, an example is taken to show that this synthetic weighting method is effective.
