The Calculating Method in Rough Set by Translating Decision Tables and Its Application

摘要/Abstract

摘要:

给出了一种计算U/IND(C)的表上作业方法,该方法无须分别求出U/IND(c1),U/IND(c2)…,U/IND(ck),省略了比较、求交的程序.依据中国科学院可持续发展研究组所提供的评价指标体系和有关数据,对中国区域科技能力水平评价问题进行了聚类实证分析,对各评价因素进行了权重挖掘,发现了各评价因素对总体水平评价的不同贡献.按照所得权重给出了新的评价结果,并根据所得结果对各区域科技能力水平现状进行了综合评判.

Abstract:

A method for calculating in rough set by translating the decision tables is given .This method need not calculate U/IND(c1), U/IND(c2), … , U/ IND(ck), omits the comparison and join calculat ion between them .Simultaneously , clustering analyses and weighting mining on the judgement of the region technology ability evaluation of China based on the judge index system are processed and involved data supported by the research group of continuous development in the Chinese academy of sciences , and new judged results are presented
