摘 要: 企业的投资决策绩效评价是个复杂系统,受多因素影响。针对我国现行企业绩效评价体系还存在指标权重失衡的问题,本文应用模糊聚类技术和粗糙集理论,将大量投资项目样本数据分别去除各个属性后进行模糊聚类,再通过对各个属性条件熵的求解,在信息熵知识的基础上确定了各个属性的互信息量,从而确定各属性的重要性,最后计算出各属性之间的权重分配,从而确定出最优的投资项目。与其它的方法比较,该方法的显著特征是无需提供问题处理的数据集合之外的任何先验信息,实例仿真证明该方法是一种基于客观事实的评价方法,企业绩效评价结果是满意的。
关 键 词: 应用数学;粗糙集;信息熵;绩效评价;模糊聚类;权重

Abstract: Performance evaluation of enterprise is a complicated system, it is effected by many elements. The paper introduced a method of getting the weight allocation based on the information entropy from practical data, so as to solve the problem of performance evaluation of enterprise; using rough set theory and fuzzy aggregation. Comparing other methods, it has the distinguishing characteristic that it needs nothing more known information. It’s proving that the performance evaluation method for investment decision-making based on information entropy of rough set was devise.
Key words: applied mathematics; rough set; information entropy; performance measurement; fuzzy aggregation; weight
