| Abstract: | Based on considering the fuzzy property of the expected profitrates and investment risk for portfolio investment and using diversification selection constraints to counteract the non-system risk, this paper presents a new fuzzy multiple objective programming model for the decision of securities investment with maximum of the expected rate of return and mimimum of the investment risk measured byβ, and the method of solution is proposed. |

| Keywords: | portfolio investment expected rate of return risk fuzzy multiobjective programming |
