数学规划在证券组合优化投资中的应用

证券市场信息是一种具有不确定性的缺失信息．证券组合投资的收益是一个动态的波值。即模型要满足(达到)两个目标：利润最大化和风险最小化。他们是互为前提的。没有绝对意义上的最优解。最优是相对的，也就是多目标决策下的次优解空间(或非劣解集)。在本文中我们在进行分析的基础上，建立一个合理的多目标初等模型，利用数学的方法将模型进化，使得模型易于求解。在此基础之上对模型做进一步的改进，使其趋于合理。

Mathematics Programming In The Application Of Investment Securities Optimization Grouping

The market information of the securities is that one kind can not have deterministically disappearance information. It is a dynamic wave value that the securities make the income invested up. On the basis of analysing , set up effective risk evaluate the mechanism in the article originally, set up one reasonable elementary model, method to utilize mathematics evolve the model, get a model which meets the general situation. Utilize this model to ask solving to the real data that is gathered , and then according to asking the result of solving to do further improvement to the model, make it tend towards it rationally.
