風(fēng)險(xiǎn)投資組合的線性規(guī)劃模型的建立及求解
[Abstract]:When comparing and implementing portfolio strategies between risk-free investments (such as depositing banks) in the market and multiple venture capital portfolios, two goals should be considered. Both goals are difficult to achieve at the same time because high returns mean high risks. This paper discusses these two problems by designing a linear programming model with portfolio. The nonlinearity of risk function is solved by selecting appropriate decision variables. By weighting the factors, we obtain the best scheme and obtain the effective investment curve. Investors according to the effective investment curve combined with their own preferences, choose their own investment direction. Finally, through nonlinear programming, it is shown that the result of linear programming has a certain tolerance to the threshold of transaction fee collection.
