摘要
针对同一资产或项目的不同投资方案的风险决策问题 ,采用衡量风险的主要指标(变异系数 ,极差 )对文献 [1 ]中基于信息论中熵值的投资风险决策进行了改进和完善 ,并结合实例应用进行了分析。
In this paper,the problem of venture decision of different investment schemes in one property or project item is discussed and the investment venture decision based on the entropy value of information theory,which was described in reference[1],is perfected with the main indexes(variation coefficient,extreme difference)to judge the venture and analyzed with an example.
