情报分析中经常会遇到多指标综合评价问题,其中指标权重确定是关键。现有的主观赋值法因过度依赖专家经验而缺乏客观性,一些客观赋值法虽以客观数据分析为基础,但其结果解释性较差。文章引入一种基于粗糙集理论的权重确定方法。该方法不需要任何先验信息,即可完成权重计算,可使情报分析结果更加客观、有效。最后以我国企业海外并购风险评价为例阐释其应用。
Intelligence analysis often encounter multi-index comprehensive evaluation, in which the weight of indicators is the key. The existing subjective valuation method lacks objectivity due to over-reliance on expert experience. Although some objective assignment methods are based on objective data analysis, their results are poorly explained. This paper introduces a weight determination method based on rough set theory. The method does not need any prior information, to complete the weight calculation, the intelligence analysis results can be more objective and effective. Finally, this paper illustrates the application of the risk evaluation of overseas mergers and acquisitions of Chinese enterprises.
