摘要
针对金融市场的不确定性,利用区间数以及Copula函数的性质,建立了在Copula-CVaR约束下的投资组合模糊选择模型.利用几何方法构造了投资选择区间,从投资者的角度考虑了不同参数下的有效投资策略,使投资过程更接近于实际情况.
Considering the uncertainty of the financial market, a fuzzy portfolio selection model is established under the Copula-CVaR constraint based on interval number and Copula function. The effective scheme based on the different parameters is considered by the investor. Therefore, the investment process is more closer and flexible to the real condition.
