摘要
本文首先建立起风险投资组合问题的线性规划模型 ,然后在通常的起作用约束集法基础上利用等值面上的锥中心线构造出一类起作用约束集法的变型算法 。
In this paper, a model of linear programming model on the combination of risk and investment is established firstly, and then on the basis of ordinary Methods of Active Set, a variation algorithm is provided with the aid of central line of cone on the equivalent plane .Subsequently the above linear programming is solved by using the variation algorithm.
