| Abstract: | Uncertainty of return is an obvious character of risk asset.Portfolio problems combined with robust optimization theory have received extensive attention recently.The limitations that the computing risk is greater than the real risk,and the optimal solution of portfolio can not be guaranteed were analysed.These limitations are caused due to the robust optimization procedure.In order to overcome these limitations,a stochastic linear programming method for solving portfolio problems was proposed,based on scen... |
