风险投资项目评估的模糊多目标群决策方法

在对影响风险投资项目评估的各种因素进行分析的基础上,依据各因素之间的隶属关系,按照系统分析方法,建立了风险项目的风险评估和效益评估指标体系。并且,运用模糊数学理论构造了风险投资项目评估的模糊多目标群决策模型。此决策方法运用不规则四边形模糊数对定性指标的语言变量值进行处理,以及对定量指标进行无量纲处理,保证了综合评估时定性指标和定量指标的兼容性。并且,运用模糊数排序乐观指数法,形成多专家多方案多指标的风险项目评估的确定性群体意见。

Evaluation of Venture Investment Project: Decision-making Based on Fuzzy Multiple Attribute Group

Based on the influential factors on evaluation of the venture investment projects, the attribute systems for venture and benefit evaluations and the method to system analyzing are presented according to the relationships of the factors. Application of fuzzy theory, a new method of venture investment evaluation, is also given based on fuzzy multiple attribute group decision-making. This method has solved the compatibility of quantitative and qualitative attributes. In addition, this method has brought the certainty result of group decision-making in multi-specialist, multi-project and multi-attribute venture investment project evaluation by fuzzy composite optimist attribute method.
