摘要
针对评判指标较多,且指标的权重没有给出的情况,利用粗糙集的相关理论,先对评判指标进行约简,再确定剩下指标的权重,最后利用区间数模糊综合评判方法得出评判结果.
In the light of more indexes , and index weighted isn＇t given. There adopts Rough Sets theories, first of all, to adjudicate the index, then make sure the rest of index weighted, finally, make use of the interval-valued fuzzy comprehensive evaluation to get final result.
