混合评价信息的随机转化方法和应用

Blended evaluation information random transformation method and its application

针对综合评价中混合评价信息共存的问题,提出一种新的处理方式.首先对混合评价信息进行预处理,转化为相同范围内统一的数据形式,在此基础上,按某分布随机生成数据,并计算其对原始评价信息的隶属程度.采用随机模拟仿真的方式对由混合信息组成的评价问题进行整体求解,得到被评价对象之间带有概率特征的可能性排序结论.所提出的方法可以使评价过程不再受单一或有限数据形式要求的局限,能够进一步拓展综合评价的实际应用范围.

To the problem that blended evaluation information exists in a same question, a processing method is proposed. Firstly, the blended information is transformed into uniform form in the same scope. Based on this, random numbers obeying certain distribution are generated, and their membership to initial information is calculated. Then, the stochastic simulation method is used to solve this evaluation question, and the possibility ranking conclusion among evaluation objects is obtained. This method can make the evaluation not be limited by single or finite data forms and can further expand the practical application range of comprehensive evaluation.
