摘要
本文根据风险投资的特点,建立了一个多属性决策问题的模型。利用"奖优罚劣"的转换办法初始化原始决策矩阵,又根据fuzzy相似类、变精度粗糙集和近似分类质量等转化和处理得到属性约简的信息系统,从而求出重要属性的客观权重来评价各个投资方案的优劣。最后利用属性权重完全未知且属性值为实数的多属性风险投资决策案例来验证模型的有效性。
According to the special features of the venture capital, this paper establishes a multi-attribute decision-making model for it. The author initializes the decision-making matrix emphasizes on the principle of "rewarding good and punishing bad", transforms and disposes it to get a information system of attribute reduction based on fuzzy similarity classes of object, variable precision rough set and approximate classification quality, then gets objective weights of main attributes for evaluating investment s...
